# Bundle Size Investigation
## Current State
**Package sizes on disk (in github-ui node_modules):**
- `@actions/languageservice`: **7.9M**
- `@actions/workflow-parser`: **1.5M**
- `@actions/expressions`: **560K**
- **Total: ~10M**
**Largest files:**
| File | Size | % of total |
|------|------|------------|
| `languageservice/dist/context-providers/events/webhooks.json` | 6.2M | 62% |
| `languageservice/dist/context-providers/events/objects.json` | 948K | 9.5% |
| `workflow-parser/dist/workflow-v1.0.json` | 112K | 1% |
| `languageservice/dist/context-providers/descriptions.json` | 20K | <1% |
## JSON File Analysis
### What `webhooks.json` is used for
Provides autocomplete and validation for `github.*` context expressions. When you type `${{ github.event.` the language service uses this data to:
- Suggest available properties based on event type (push, pull_request, etc.)
- Provide descriptions for hover tooltips
- Validate property access is valid for the event type
### Field usage analysis
| Field | Location | Size | Used for Autocomplete | Used for Validation | Used for Hover |
|-------|----------|------|----------------------|---------------------|----------------|
| `bodyParameters[].description` | Inside each param | Part of bodyParams | ✅ Documentation popup | ✅ Property existence | ✅ Descriptions |
| `bodyParameters[].name/type/etc` | Inside each param | 1.55 MB total | ✅ Property names | ✅ Property existence | ✅ Structure |
| `description` | Top-level on event | 17 KB | ❌ Defined but unused | ❌ | ❌ |
| `summary` | Top-level on event | 155 KB | ❌ | ❌ | ❌ |
| `availability` | Top-level on event | 7 KB | ❌ | ❌ | ❌ |
| `category` | Top-level on event | 3 KB | ❌ | ❌ | ❌ |
| `action` | Top-level on event | 2 KB | ❌ | ❌ | ❌ |
**Key insight:** `bodyParameters` (including nested `description` fields) is used for ALL features. The **top-level** fields (`summary`, `description`, `availability`, `category`, `action`) are defined in the TypeScript types but never actually accessed in code - they can be stripped.
### Why top-level `description`/`summary` shouldn't be used for workflow events
**Question:** Could we use the webhooks.json top-level `description` or `summary` fields to enhance autocomplete/hover for the `on:` field?
**Answer:** No - they serve different purposes and the existing solution is better.
**Comparison:**
| Source | Example for `push` | Purpose |
|--------|-------------------|---------|
| `workflow-v1.0.json` (current) | "Runs your workflow when you push a commit or tag." | **User-facing** - explains what triggers the workflow |
| `webhooks.json` description | "A push was made to a repository branch..." | **API-facing** - describes the GitHub API event |
| `webhooks.json` summary | "This event occurs when a commit or tag is pushed. To subscribe to this event, a GitHub App must have at least read-level access..." | **App developer-facing** - API permissions info |
**The current solution is correct:**
- `workflow-v1.0.json` contains workflow-specific event descriptions written for GitHub Actions users
- These are shown in autocomplete/hover when completing `on: push`, `on: pull_request`, etc.
- Located in `languageservice/src/value-providers/definition.ts` line 46: `description: def.description`
**The webhooks.json descriptions would be wrong:**
- Written for GitHub App developers, not GitHub Actions users
- Include irrelevant details (API permissions, subscription info)
- Don't explain what happens in the context of a workflow
**Conclusion:** Keep the top-level fields stripped - they're not needed and would be confusing if used.
### Minification analysis
| File | Pretty Size | Minified Size | Savings |
|------|-------------|---------------|---------|
| `webhooks.json` | 4.1 MB | 1.6 MB | **2.5 MB (60.5%)** |
| `objects.json` | 666 KB | 325 KB | **341 KB (51.3%)** |
| `workflow-v1.0.json` | 91 KB | 70 KB | **22 KB (23.5%)** |
**The files are NOT minified!** Just minifying saves 60%.
### Compression analysis (gzip)
Production servers typically gzip assets. Here's what matters for network transfer:
| File | Original | Minified | Gzipped | Min+Gzip |
|------|----------|----------|---------|----------|
| `webhooks.json` | 4.0 MB | 1.6 MB | 198 KB | **90 KB** |
| `objects.json` | 651 KB | 317 KB | 38 KB | **23 KB** |
| `workflow-v1.0.json` | 91 KB | 70 KB | 13 KB | **13 KB** |
**What matters for different concerns:**
| Concern | What matters |
|---------|--------------|
| **Network transfer** | Compressed size (gzip/brotli) - already small (~126 KB total) |
| **npm package size** | Uncompressed size on disk - affects install times |
| **Memory usage** | Parsed JSON object size in memory |
| **Parse time** | Uncompressed size (must decompress before parsing) |
**Key insight:** Network transfer is NOT the main concern (~126 KB gzipped). Minifying still matters for:
- Smaller npm package size (better install times)
- Less to decompress on client
- Faster JSON parsing (less text to parse)
## How the files are generated
The JSON files are **auto-generated** from GitHub's official REST API description:
```
npm run update-webhooks
```
**Source:** `github:github/rest-api-description` (GitHub's OpenAPI spec)
**Generation script:** `languageservice/script/webhooks/index.ts`
- Reads webhook definitions from the dereferenced OpenAPI schema
- Extracts body parameters, descriptions, summaries
- Runs deduplication to create `objects.json` (shared parameters stored once, referenced by index)
- Outputs pretty-printed JSON (not minified)
**Current deduplication strategy (`deduplicate.ts`):**
- Finds body parameters that appear in multiple webhooks
- Stores them once in `objects.json` array
- Replaces duplicates with numeric index references in `webhooks.json`
**Optimization opportunities in generation:**
1. Add minification step (remove whitespace) - easy, ~60% savings
2. Strip unused fields (`summary`, `availability`, `category`, `action`) - ~10% additional savings
3. Consider more aggressive deduplication (e.g., dedupe descriptions, nested objects)
### `workflow-v1.0.json` (workflow schema)
**Hand-authored** - not generated. Located in `workflow-parser/src/`.
Optimization: Minify at build time (112K pretty → smaller minified).
### Other Small JSON Files
| File | Purpose | Pretty | Minified | Further Optimized |
|------|---------|--------|----------|-------------------|
| `descriptions.json` | Hover descriptions for contexts/functions | 18 KB | 17 KB | N/A (all used) |
| `schedule.json` | Sample `github.event` for schedule trigger | 5.7 KB | 5.1 KB | **1.8 KB** (strip values) |
| `workflow_call.json` | Sample `github.event` for reusable workflows | 7.3 KB | 6.5 KB | **2.3 KB** (strip values) |
**Why `schedule.json` / `workflow_call.json` exist:**
These events are NOT webhooks - they're internal GitHub Actions triggers that don't appear in the REST API webhook definitions. The files provide sample `github.event` payloads so the language service knows what properties to autocomplete:
```
User types: ${{ github.event.repository.owner.login }}
Language service walks schedule.json to find valid property names
```
The code (`eventPayloads.ts` lines 109-116) uses `mergeObject()` to recursively extract property **names** - the actual values are never used.
**Key insight for `schedule.json` / `workflow_call.json`:** These files provide sample event payloads. The code only uses property **names** (for autocomplete like `github.event.repository.owner.login`), not values. The actual values (URLs, IDs, emails) can be replaced with `null`:
```javascript
// Original (5.1 KB)
{"repository":{"id":186853002,"name":"Hello-World","owner":{"login":"Codertocat",...},...},...}
// Stripped (1.8 KB) - same autocomplete functionality
{"repository":{"id":null,"name":null,"owner":{"login":null,...},...},...}
```
**Savings:** ~65% smaller for these files.
## JSON File Maintenance & Documentation
### TODO: Document maintenance procedures
| File | Source | How to Update | Documented? |
|------|--------|---------------|-------------|
| `webhooks.json` + `objects.json` | `npm run update-webhooks` from `rest-api-description` | Run script | ⚠️ Partial (in script) |
| `workflow-v1.0.json` | Hand-authored | Manual edits | ❌ No |
| `descriptions.json` | Hand-authored | Manual edits | ❌ No |
| `schedule.json` | Hand-authored sample payload | Manual edits | ❌ No - unclear origin |
| `workflow_call.json` | Hand-authored sample payload | Manual edits | ❌ No - unclear origin |
### Historical context (from git history):
- **`schedule.json`** - Added in commit `b68ac91` (Dec 2022) by Beth Brennan in "Use payload schema for events"
- Uses "Codertocat/Hello-World" sample data (appears to be from GitHub's webhook documentation examples)
- No documentation on where this came from or how to update it
- **Question:** Is this based on a real scheduled workflow run? How do we know it includes all possible properties?
- **`workflow_call.json`** - Same commit, similar questions
- **Many other event JSON files** were added in that same commit, but were later replaced by the generated `webhooks.json` system. Only `schedule.json` and `workflow_call.json` remain as manual files because they're not real webhooks.
### Questions to answer:
1. **`schedule.json`** - Where did this sample payload come from? Is it based on a real event? How do we know it's complete/accurate? Does it need updating when GitHub adds new repository properties?
2. **`workflow_call.json`** - Same questions. Was this captured from an actual workflow run?
3. **`descriptions.json`** - Are these descriptions synced from docs.github.com or manually maintained? How do we keep them up to date?
4. **`workflow-v1.0.json`** - What's the process for adding new workflow syntax (new keys, new event types)?
### Recommended actions:
1. **Add README files** - Each JSON file should have documentation explaining what it's for, how to update it, and who maintains it
2. **Automate where possible** - Could `schedule.json` be generated from a real scheduled workflow run's `github.event`? Could we capture a sample automatically?
3. **Add tests** - Validate that sample payloads match expected structure
### ⚠️ BUG: `workflow_call.json` may be incorrect/useless
**Finding:** For `on: workflow_call` (reusable workflows), the `github.event` context is **inherited from the calling workflow**. If the caller was triggered by `push`, then `github.event` contains push data. If by `pull_request`, it contains PR data.
**Current behavior in `github.ts`:**
```typescript
// Line 87-89 - For VALIDATION mode, returns Null (any value allowed)
if (eventsConfig.workflow_call && mode == Mode.Validation) {
return new data.Null();
}
// But for COMPLETION/HOVER mode, falls through and uses workflow_call.json!
```
**Problem:** `workflow_call.json` contains generic repo/sender/org data, but this is WRONG for autocomplete. When you type `${{ github.event.` in a reusable workflow, showing `repository`, `sender`, etc. is misleading because:
- The actual properties depend on how the workflow was called
- Could be push properties, PR properties, or anything else
**Recommendation:**
- Either return `Null` for completion/hover too (show nothing, since we can't know)
- Or remove `workflow_call.json` entirely since it's actively misleading
- This would save 7KB and fix a bug!
## npm Package Sizes
The actual npm package sizes (gzipped tarballs) are much smaller than disk size:
| Package | Disk Size | Package Size (gzipped) | Unpacked |
|---------|-----------|------------------------|----------|
| `@actions/languageservice` | 7.9M | **368 KB** | 7.7 MB |
| `@actions/workflow-parser` | 1.5M | **98 KB** | 548 KB |
| `@actions/expressions` | 560K | **34 KB** | 153 KB |
| **Total** | ~10M | **~500 KB** | ~8.4 MB |
**Key insight:** npm install downloads ~500KB gzipped. The disk/memory impact is ~8.4 MB unpacked.
## Dependencies Analysis
**Direct dependencies:**
| Package | Disk Size | Used By | Notes |
|---------|-----------|---------|-------|
| `yaml` | 1.4 MB | workflow-parser, languageservice | Full YAML parser, well-structured |
| `cronstrue` | 1.4 MB | workflow-parser | Cron → human text. Main: 44KB (no i18n) |
| `vscode-languageserver-types` | 396 KB | languageservice | Type definitions for LSP |
| `vscode-languageserver-textdocument` | 72 KB | languageservice | Text document handling |
| `vscode-uri` | 256 KB | languageservice | URI parsing |
**Observations:**
- `cronstrue` has a 44KB main entry (without i18n) vs 238KB with i18n. Bundlers should use the smaller one.
- `yaml` is necessary - no lighter alternative for full YAML parsing
- `vscode-*` packages are minimal and necessary for LSP compatibility
## Areas to Investigate
1.**Total bundle size** - Analyzed above
2.**Specific heavy dependencies** - `cronstrue` and `yaml` analyzed
3. **Tree-shaking** - Whether unused code is being properly eliminated
4.**Load time impact** - Lazy-loaded in github-ui via dynamic import()
5.**JSON files for event validation** - Main culprit (6.2MB webhooks.json)
6.**Minifying the workflow schema JSON file** - 112K → can be minified
## Potential Optimizations
### High Impact
1. **Drop 31 unused webhook events** - Events like `installation`, `marketplace_purchase`, `sponsorship`, `star`, `team`, etc. are in `webhooks.json` but cannot be used as workflow triggers. Confirmed against [GitHub's official docs](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows).
| Metric | Before | After | Savings |
|--------|--------|-------|---------|
| Events | 63 | 32 | 31 dropped |
| Size | 1.76 MB | 1.42 MB | **19%** |
**Events to drop:**
```
code_scanning_alert, commit_comment, dependabot_alert, deploy_key,
github_app_authorization, installation, installation_repositories,
installation_target, marketplace_purchase, member, membership, meta,
org_block, organization, package, ping, projects_v2, projects_v2_item,
pull_request_review_thread, repository, repository_import,
repository_vulnerability_alert, secret_scanning_alert,
secret_scanning_alert_location, security_advisory, security_and_analysis,
sponsorship, star, team, team_add, workflow_job
```
2. **Strip unused fields** - Remove `summary`, `availability`, `category`, `action` fields that are never used by the language service. Only `bodyParameters` and `descriptionHtml` are needed.
3. **Minify JSON files** - Currently pretty-printed with whitespace. Minifying saves ~60%.
4. **Combined impact estimate:**
| Optimization | webhooks.json | objects.json |
|--------------|---------------|--------------|
| Original | 6.2 MB | 948 KB |
| Drop unused events | 5.0 MB (-19%) | 770 KB (-19%) |
| Strip unused fields | 3.0 MB (-40%) | 460 KB (-40%) |
| Minify | 1.2 MB (-60%) | 225 KB (-52%) |
| **Gzipped (network)** | **~60 KB** | **~20 KB** |
5. **Add `"sideEffects"` to all package.json files** - Enable tree-shaking across all packages:
- `expressions/package.json`: `"sideEffects": false`
- `workflow-parser/package.json`: `"sideEffects": false`
- `languageservice/package.json`: `"sideEffects": ["./dist/context-providers/events/eventPayloads.js"]`
### Medium Impact
6. **Minify `workflow-v1.0.json` schema (112K)** - Strip whitespace. Note: This file is hand-authored, not generated from webhook data.
7. **Minify and strip small JSON files** - `schedule.json`, `descriptions.json`:
- Minify all (remove whitespace)
- Strip values from `schedule.json` (only property names are used)
8. **Investigate `workflow_call.json` usage** - See bug section above. This file may be incorrect/useless:
- For `on: workflow_call`, `github.event` is inherited from the calling workflow
- Current code returns `Null` for validation (correct) but uses `workflow_call.json` for completion (incorrect?)
- Options: Remove file entirely, or fix code to return `Null` for all modes
- Saves 7KB + potentially fixes misleading autocomplete
9. **Lazy-load event validation data** - Refactor `eventPayloads.ts` to load JSON on first use instead of at import time.
### Low Impact / Further Investigation
10. **Tree-shake unused exports** - Ensure webpack is eliminating dead code.
11. **Evaluate `cronstrue` size** - Check if it's worth keeping or replacing with lighter alternative.
11. **Bundle analysis** - Run webpack-bundle-analyzer to see actual bundled sizes after minification/compression.
## Implementation Plan
### Phase 1: Update generation script (`languageservice/script/webhooks/index.ts`)
1. Add list of valid workflow trigger events (whitelist)
2. Filter out events not in whitelist during generation
3. Strip unused fields (`summary`, `availability`, `category`, `action`)
4. Output minified JSON (`JSON.stringify(data)` instead of `JSON.stringify(data, null, 2)`)
### Phase 1b: Minify/optimize small hand-authored JSON files
1. Minify `descriptions.json` (18 KB → 17 KB)
2. Strip values & minify `schedule.json` (5.7 KB → 1.8 KB)
3. Strip values & minify `workflow_call.json` (7.3 KB → 2.3 KB)
4. Minify `workflow-v1.0.json` (112 KB → ~90 KB)
### Phase 2: Add sideEffects to all package.json files
1. Add `"sideEffects": false` to `expressions/package.json`
2. Add `"sideEffects": false` to `workflow-parser/package.json`
3. Add `"sideEffects": ["./dist/context-providers/events/eventPayloads.js"]` to `languageservice/package.json`
### Phase 3: (Optional) Refactor for lazy loading
1. Move JSON imports inside functions
2. Remove top-level hydration code, make it lazy
### Phase 4: Automated JSON updates via GitHub Actions
Create workflows to automatically keep JSON files up to date:
#### 4a: Webhook JSON auto-update workflow
```yaml
# .github/workflows/update-webhooks.yml
name: Update webhook definitions
on:
schedule:
- cron: '0 0 * * 1' # Weekly on Monday
workflow_dispatch: # Manual trigger
jobs:
update:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
- run: npm ci
- run: npm run update-webhooks
- name: Create PR if changes
uses: peter-evans/create-pull-request@v5
with:
title: "chore: Update webhook definitions"
body: |
Automated update from `rest-api-description` package.
This PR was created automatically by the update-webhooks workflow.
branch: auto/update-webhooks
delete-branch: true # Delete old branch, creates fresh PR each time
commit-message: "chore: Update webhook definitions"
```
#### 4b: Schedule/workflow_call JSON auto-update workflow
Create a workflow that runs an actual scheduled workflow and captures `github.event`:
```yaml
# .github/workflows/capture-schedule-payload.yml
name: Capture schedule event payload
on:
schedule:
- cron: '0 0 1 * *' # Monthly on the 1st
workflow_dispatch:
jobs:
capture:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Capture github.event
run: |
echo '${{ toJSON(github.event) }}' > /tmp/schedule-event.json
# Strip to just property structure (values → null)
node -e "
const fs = require('fs');
const strip = (o) => {
if (Array.isArray(o)) return o.length ? [strip(o[0])] : [];
if (o && typeof o === 'object') return Object.fromEntries(
Object.entries(o).map(([k,v]) => [k, strip(v)])
);
return null;
};
const data = JSON.parse(fs.readFileSync('/tmp/schedule-event.json'));
const stripped = strip(data);
fs.writeFileSync(
'languageservice/src/context-providers/events/schedule.json',
JSON.stringify(stripped, null, 2)
);
"
- name: Create PR if changes
uses: peter-evans/create-pull-request@v5
with:
title: "chore: Update schedule.json payload structure"
body: |
Captured fresh `github.event` structure from a real scheduled workflow run.
This ensures autocomplete suggestions match the actual event payload.
branch: auto/update-schedule-json
delete-branch: true
commit-message: "chore: Update schedule.json from live event"
```
#### 4c: Workflow_call payload capture
Similar approach - create a reusable workflow that calls itself and captures `github.event`:
```yaml
# .github/workflows/capture-workflow-call-payload.yml
name: Capture workflow_call event payload
on:
workflow_call:
workflow_dispatch:
jobs:
capture:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Capture and update workflow_call.json
if: github.event_name == 'workflow_call'
run: |
# Similar to schedule capture above
echo '${{ toJSON(github.event) }}' | node -e "..." > workflow_call.json
- name: Trigger self as reusable workflow
if: github.event_name == 'workflow_dispatch'
uses: ./.github/workflows/capture-workflow-call-payload.yml
```
**Benefits:**
- JSON files stay up to date automatically
- PRs are created for review (not auto-merged)
- Captures real event structures, not guessed samples
- Weekly/monthly schedule catches GitHub API changes
## Validation Stages Analysis
The current `validate()` function does everything in one pass. We could split it into stages that load progressively:
### Current Loading Cascade
```
validate() called
└─ imports workflow-parser
└─ imports workflow-v1.0.json (112KB) ← loaded immediately
└─ parseWorkflow() → YAML parse + schema validation
└─ additionalValidations()
└─ getContext() → imports github.ts
└─ imports eventPayloads.ts
└─ imports webhooks.json (6.2MB) ← loaded immediately
```
### Potential Validation Stages
| Stage | What it validates | Data needed | Size |
|-------|-------------------|-------------|------|
| **1. YAML Syntax** | Valid YAML? Quotes closed? Indentation? | YAML parser (bundled) | ~0 |
| **2. Workflow Schema** | Valid `jobs:`, `steps:`, `runs-on:`? | `workflow-v1.0.json` | 112KB |
| **3. Expression Syntax** | Valid `${{ }}` syntax? Functions exist? | Expression parser | ~0 |
| **4. Context Validation** | `github.sha`, `env.FOO` exist? | Just code | ~0 |
| **5. Event Payload Validation** | `github.event.pull_request.title` exists? | `webhooks.json` | 6.2MB |
### Key Insight
Stages 1-4 can run with minimal data (~112KB). Only Stage 5 needs the 6.2MB webhook data.
**Expression syntax** (`${{ secrets.FOO }}`) is different from **event payload validation** (`${{ github.event.issue.number }}`):
- Expression syntax: Is this a valid expression? Does the function exist?
- Event payload: Does this specific property exist on the `pull_request` event?
### Options for Progressive Loading
**Option A: Lazy load webhooks.json (simplest)**
```typescript
// eventPayloads.ts - defer import until first use
let webhooksData: Webhooks | null = null;
async function getWebhooks() {
if (!webhooksData) {
const { default: data } = await import("./webhooks.json");
webhooksData = data;
}
return webhooksData;
}
```
- Pro: Minimal code changes
- Con: Still blocks when github.event.* is first accessed
**Option B: Multi-pass validation in languageservice**
```typescript
// New exports from @actions/languageservice
export { validateSchema } from "./validate-schema"; // Fast
export { validateExpressions } from "./validate-expressions"; // Needs webhooks
export { validate } from "./validate"; // Combined (current)
```
- Pro: Clean API, consumer controls loading
- Con: More work, API change
**Option C: Multi-pass validation in github-ui**
```typescript
// github-ui can show partial results
const schemaErrors = await validate(doc); // Returns what it can immediately
// Later, more errors may arrive as webhooks.json loads
```
- Pro: No languageservice changes
- Con: Complex state management in consumer
### Recommendation
1. **Phase 1**: Minify + strip unused data (reduce 6.2MB → ~1.2MB)
2. **Phase 2**: Lazy load webhooks.json in `eventPayloads.ts`
3. **Phase 3** (future): Consider multi-pass API if needed
The lazy loading approach gives 90% of the benefit with 10% of the complexity.
## Side Effects Analysis
Need to verify the packages have no side effects before adding `"sideEffects": false`:
- [x] `@actions/languageservice` - Has ONE file with side effects
- [x] `@actions/workflow-parser` - ✅ No side effects
- [x] `@actions/expressions` - ✅ No side effects
Common side effects to look for:
- Top-level function calls (not just definitions)
- Modifying global objects (`Object.prototype`, `window`, etc.)
- Polyfills
- CSS imports (not applicable here)
### JSON Files Imported at Top Level

| languageservice | `eventPayloads.ts` | `objects.json` | 948 KB | ⚠️ YES (mutation) |

| expressions | (none) | (none) | - | ❌ No |
### Findings
**`@actions/expressions`** - ✅ No side effects
- No JSON imports
- No top-level code execution
- Can use `"sideEffects": false`
**`@actions/workflow-parser`** - ✅ No side effects
- `workflow-schema.ts` imports `workflow-v1.0.json` at top level BUT:
- Only exports a function `getWorkflowSchema()` with lazy initialization
- No top-level function calls or mutations
- Can use `"sideEffects": false`
**`@actions/languageservice`** - ⚠️ HAS ONE FILE with side effects
`descriptions.ts` - ❌ No side effects
- Imports `descriptions.json` (20KB) at top level
- Only exports functions, no top-level execution
`eventPayloads.ts` - ⚠️ HAS SIDE EFFECTS
```typescript
// Lines 3-7: JSON imports at top level (7.2MB total)
import webhookObjects from "./objects.json";
import webhooks from "./webhooks.json";
import schedule from "./schedule.json";
import workflow_call from "./workflow_call.json";
// Lines 85-93: Executes at module load time, mutates data
getWebhookPayload("workflow_dispatch", "default");
const inputs = webhookPayloads?.["workflow_dispatch"]?.["default"].bodyParameters.find(p => p.name === "inputs");
if (inputs) {
delete inputs.childParamsGroups;
}
```
### Recommended `sideEffects` Configuration
**`expressions/package.json`:**
```json
"sideEffects": false
```
**`workflow-parser/package.json`:**
```json
"sideEffects": false
```
**`languageservice/package.json`:**
```json
"sideEffects": ["./dist/context-providers/events/eventPayloads.js"]
```
**Impact:** Allows webpack to tree-shake unused exports. Without this, webpack assumes all imports may have side effects and keeps everything.
### Optional: Refactor `eventPayloads.ts` to Remove Side Effects
To allow `"sideEffects": false` for the entire languageservice package, refactor the mutation code:
```typescript
// Before: Top-level mutation
getWebhookPayload("workflow_dispatch", "default");
const inputs = webhookPayloads?.["workflow_dispatch"]?.["default"].bodyParameters.find(p => p.name === "inputs");
if (inputs) {
delete inputs.childParamsGroups;
}
// After: Lazy initialization inside function
let initialized = false;
function ensureInitialized() {
if (initialized) return;
initialized = true;
// ... mutation code here
}
export function getEventPayload(...) {
ensureInitialized();
// ... rest of function
}
```
This would allow full tree-shaking AND defer the 7.2MB JSON load until first use.

# Bundle Size Optimization Plan
## Goal
Reduce `@actions/languageservice` package size from **7.9 MB** to **~1.5 MB** (80% reduction).
## Summary
| Phase | Change | Savings | Effort |
|-------|--------|---------|--------|
| 1a | Minify all JSON | 60% | Low |
| 1b | Strip unused fields | 10% | Low |
| 1c | Drop unused events | 19% | Low |
| 2 | Lazy-load webhooks.json (optional) | Faster initial load | Medium |
## Phase 1: Optimize JSON files
### What each JSON file is used for
| File | Package | Purpose |
|------|---------|---------|
| `webhooks.json` | languageservice | Autocomplete/validation for `github.event.*` expressions. Contains event payload schemas from GitHub's REST API. |
| `objects.json` | languageservice | Deduplicated parameter definitions shared across webhooks (reduces duplication in webhooks.json). |
| `workflow-v1.0.json` | workflow-parser | Workflow schema defining valid YAML structure (`jobs`, `steps`, `runs-on`, event triggers, etc.). |
| `descriptions.json` | languageservice | Hover descriptions for contexts (`github`, `env`, `secrets`) and built-in functions (`format`, `contains`, etc.). |
| `schedule.json` | languageservice | Sample `github.event` payload for `on: schedule` trigger (not a real webhook, manually authored). |
| `workflow_call.json` | languageservice | Sample `github.event` payload for `on: workflow_call` trigger (not a real webhook, manually authored). |
### Impact table
| File | Original | Strip | Drop | Minify | Gzip | All (no Gzip) | All (w/ Gzip) |
|------|----------|-------|------|--------|------|---------------|---------------|
| `webhooks.json` | 6.2 MB | 5.6 MB | 5.0 MB | 2.4 MB | 188 KB | **1.0 MB** | **50 KB** |
| `objects.json` | 948 KB | N/A | 770 KB | 460 KB | 36 KB | **180 KB** | **18 KB** |
| `workflow-v1.0.json` | 112 KB | N/A | N/A | 70 KB | 13 KB | **70 KB** | **12 KB** |
| `descriptions.json` | 18 KB | N/A | N/A | 17 KB | 3 KB | **17 KB** | **3 KB** |
| `schedule.json` | 5.7 KB | N/A | N/A | 5.1 KB | 1 KB | **5.1 KB** | **1 KB** |
| `workflow_call.json` | 7.3 KB | N/A | N/A | 6.5 KB | 1 KB | **6.5 KB** | **1 KB** |
| **Total** | **7.3 MB** | | | | **~240 KB** | **~1.3 MB** | **~85 KB** |
- **Strip** = Remove unused fields (`summary`, `availability`, `category`, `action`)
- **Drop** = Remove 31 non-trigger events (`installation`, `star`, `team`, etc.)
- **Minify** = Remove whitespace (`JSON.stringify(data)` instead of `JSON.stringify(data, null, 2)`)
- **Gzip** = Network transfer size (free - handled automatically by browser/server)
### 1a. Minify all JSON files
**Generated files** (`webhooks.json`, `objects.json`):
- Update `languageservice/script/webhooks/index.ts`
- These are generated via `npm run update-webhooks` from GitHub's REST API spec
- Use `JSON.stringify(data)` instead of `JSON.stringify(data, null, 2)`
**Hand-authored files** (`workflow-v1.0.json`, `descriptions.json`, `schedule.json`, `workflow_call.json`):
- Add minification step to build scripts
### 1b. Strip unused fields from webhooks.json
Remove before writing:
- `summary`
- `availability`
- `category`
- `action`
### 1c. Drop non-trigger events from webhooks.json
Keep only events that can trigger workflows ([docs](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows)). Drop 31 events:
```
code_scanning_alert, commit_comment, dependabot_alert, deploy_key,
github_app_authorization, installation, installation_repositories,
installation_target, marketplace_purchase, member, membership, meta,
org_block, organization, package, ping, projects_v2, projects_v2_item,
pull_request_review_thread, repository, repository_import,
repository_vulnerability_alert, secret_scanning_alert,
secret_scanning_alert_location, security_advisory, security_and_analysis,
sponsorship, star, team, team_add, workflow_job
```
**Expected result:** Total JSON 7.3 MB → ~1.3 MB (82% reduction)
---
## Phase 2: Lazy loading (optional)
Refactor `eventPayloads.ts` to load JSON on first use:
```typescript
let webhooksData: Webhooks | null = null;
async function getWebhooks() {
if (!webhooksData) {
const { default: data } = await import("./webhooks.json");
webhooksData = hydrate(data);
}
return webhooksData;
}
```
**Benefit:** Faster initial load when `github.event.*` isn't used.
---
## Current github-ui architecture
github-ui lazy-loads the language service via dynamic import:
```typescript
// workflow-editor-next.ts
let languageServicePromise: Promise<typeof import('./workflow-editor-language-service')> | null = null
async function getLanguageServiceModule() {
if (!languageServicePromise) {
languageServicePromise = import('./workflow-editor-language-service')
}
return languageServicePromise
}
```
**What this means:**
- The language service is only loaded when the workflow editor needs autocomplete/hover/validation
- Webpack code-splits it into a separate chunk
- The ~7.9 MB package is NOT loaded on initial page load
**Why Phase 1 is the priority:**
- When the language service chunk IS loaded, it still loads all 7.3 MB of JSON
- Reducing JSON to ~1.3 MB directly reduces this chunk size
- No changes needed in github-ui - the benefit is automatic
---
## Not doing
- **Tree-shaking / `sideEffects`** - github-ui imports `complete`, `hover`, and `validate` together, and all three depend on the same webhook JSON. Tree-shaking can't eliminate any of it.
- **Replacing dependencies** - `yaml` and `cronstrue` are appropriately sized
- **Multi-pass validation API** - Too complex for the benefit
- **Further deduplication** - Current object deduplication is sufficient
---
## Future considerations
- **`workflow_call.json` may be incorrect** - For `on: workflow_call`, `github.event` is inherited from the calling workflow (could be push, pull_request, etc.). The current file shows generic properties which may be misleading for autocomplete. Consider returning `Null` for all modes or removing the file entirely.
---
## Success metrics
| Metric | Before | After |
|--------|--------|-------|
| `webhooks.json` | 6.2 MB | ~1.2 MB |
| `objects.json` | 948 KB | ~225 KB |
| Total package (disk) | 7.9 MB | ~1.5 MB |
| npm tarball (gzipped) | 368 KB | ~80 KB |

**Note:** No stripping applicable - this is a hand-authored schema where all fields are used.
## Recommended Action
**For webhooks.json and objects.json:** Strip + Minify
- Modify `languageservice/script/webhooks/index.ts` to:
1. Strip unused fields (`summary`, `availability`, `category`, `action`) before writing
2. Use `JSON.stringify(obj)` instead of `JSON.stringify(obj, null, 2)` to minify
- Gzip is handled automatically by github-ui's production server
**For workflow-v1.0.json:** Minify at build time
- Add a build step to minify the JSON before publishing
**Expected savings:**
- npm package size: 4.78 MB → 1.77 MB (63% reduction)
- Network transfer (gzip): 224 KB → 91 KB (59% reduction)

# JSON Data Files
This document describes the JSON data files used by the language service packages and how they are maintained.
## Overview
The language service uses several JSON files containing schema definitions, webhook payloads, and other metadata. To reduce bundle size, these files are:
1. **Optimized at generation time** — unused events are dropped, unused fields are stripped
2. **Minified at build time** — whitespace is removed to produce `.min.json` files
The source `.json` files are human-readable and checked into the repository. The `.min.json` files are generated during build and gitignored.
## Files
### languageservice
| File | Description |
|------|-------------|
| `src/context-providers/events/webhooks.json` | Webhook event payload schemas for autocompletion |
| `src/context-providers/events/objects.json` | Deduplicated shared object definitions referenced by webhooks |
| `src/context-providers/events/schedule.json` | Schedule event context data |
| `src/context-providers/events/workflow_call.json` | Reusable workflow call context data |
| `src/context-providers/descriptions.json` | Context variable descriptions for hover |
### workflow-parser
| File | Description |
|------|-------------|
| `src/workflow-v1.0.json` | Workflow YAML schema definition |
## Generation
### Webhooks and Objects
The `webhooks.json` and `objects.json` files are generated from the [GitHub REST API description](https://github.com/github/rest-api-description):
```bash
cd languageservice
npm run update-webhooks
```
This script:
1. Fetches webhook schemas from the GitHub API description
2. **Validates** all events are categorized (fails if new events are found)
3. **Drops** events that aren't valid workflow triggers (see [Dropped Events](#dropped-events))
4. **Strips** unused fields like `description` and `summary` (see [Stripped Fields](#stripped-fields))
5. **Deduplicates** shared object definitions into `objects.json`
6. Writes the optimized, pretty-printed JSON files
### Handling New Webhook Events
When GitHub adds a new webhook event, the script will fail with an error like:
```
ERROR: New webhook event(s) detected!
The following events are not categorized:
- new_event_name
Action required:
1. Check if the event is a valid workflow trigger
2. Add the event to DROPPED_EVENTS or KEPT_EVENTS
```
**To resolve:**
1. Check [Events that trigger workflows](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows)
2. Edit `languageservice/script/webhooks/index.ts`:
- Add to `KEPT_EVENTS` if it's a valid workflow trigger
- Add to `DROPPED_EVENTS` if it's GitHub App or API-only
3. Run `npm run update-webhooks` and commit the changes
#### Viewing Full Unprocessed Data
To see all available fields and events before optimization:
```bash
npm run update-webhooks -- --all
```
This generates `webhooks.all.json` and `objects.all.json` (gitignored) containing the complete unprocessed data from the GitHub API.
### Other Files
The other JSON files (`schedule.json`, `workflow_call.json`, `descriptions.json`, `workflow-v1.0.json`) are manually maintained.
## Minification
At build time, all JSON files are minified (whitespace removed) to produce `.min.json` versions:
```bash
npm run minify-json
```
This runs automatically via `prebuild` and `pretest` hooks, so you don't need to run it manually.
The code imports the minified versions:
```ts
import webhooks from "./events/webhooks.min.json"
```
## CI Verification
CI verifies that generated source files are up-to-date:
1. Runs `npm run update-webhooks` to regenerate webhooks.json and objects.json
2. Checks for uncommitted changes with `git diff --exit-code`
The `.min.json` files are generated at build time and are not committed to the repository.
If the build fails, run `cd languageservice && npm run update-webhooks` locally and commit the changes.
## Dropped Events
Webhook events that aren't valid workflow `on:` triggers are dropped (e.g., `installation`, `ping`, `member`, etc.). These are GitHub App or API-only events.
See `DROPPED_EVENTS` in `script/webhooks/index.ts` for the full list.
## Stripped Fields
Unused fields are stripped to reduce bundle size. For example:
```json
// Before (from webhooks.all.json)
{
"type": "object",
"name": "issue",
"in": "body",
"description": "The issue itself.",
"isRequired": true,
"childParamsGroups": [...]
}
// After (webhooks.json)
{
"name": "issue",
"description": "The issue itself.",
"childParamsGroups": [...]
}
```
Only `name`, `description`, and `childParamsGroups` are kept — these are used for autocompletion and hover docs.
To compare all fields vs stripped, run `npm run update-webhooks -- --all` and diff the `.all.json` files against the regular ones.
See `EVENT_ACTION_FIELDS` and `BODY_PARAM_FIELDS` in `script/webhooks/index.ts` to modify what gets stripped.
## Schema Synchronization
The `workflow-v1.0.json` schema defines which activity types are valid for each workflow trigger event. A test in `workflow-parser/src/schema-sync.test.ts` verifies these stay in sync with `webhooks.json`.
### When the Test Fails
If the schema-sync test fails, you'll see an error like:
```
Event "pull_request" is missing activity type "new_activity" in workflow-v1.0.json
```
**To resolve:**
1. Check [Events that trigger workflows](https://docs.github.com/en/actions/writing-workflows/choosing-when-your-workflow-runs/events-that-trigger-workflows) to verify the activity type is a valid workflow trigger:
- Find the event section (e.g., "pull_request")
- Look at the "Activity types" table — it lists which types can be used in `on.<event>.types`
- If the type is listed there, it's a valid workflow trigger
- If the type only appears in webhook docs but NOT in the workflow trigger docs, it's webhook-only
2. If it IS a valid workflow trigger:
- Edit `workflow-parser/src/workflow-v1.0.json`
- Find the `<event>-activity-type` definition (e.g., `pull-request-activity-type`)
- Add the new activity type to `allowed-values`
- Update the `description` in `<event>-activity` to list all types
- Run `npm test` to regenerate the minified JSON
3. If it is NOT a valid workflow trigger (webhook-only):
- Edit `workflow-parser/src/schema-sync.test.ts`
- Add the type to `WEBHOOK_ONLY` for that event
### Known Discrepancies
The test tracks several types of known discrepancies:
| Category | Purpose | Example |
|----------|---------|---------|
| `WEBHOOK_ONLY` | Types in webhooks that aren't valid workflow triggers | `check_suite.requested` |
| `SCHEMA_ONLY` | Types valid for workflows but missing from webhooks | `registry_package.updated` |
| `NAME_MAPPINGS` | Different names for the same concept | `project_column`: webhook uses `edited`, schema uses `updated` |
### Bidirectional Checking
The test checks both directions:
- **webhooks → schema**: Ensures all webhook activity types are in the schema (or listed in `WEBHOOK_ONLY`)
- **schema → webhooks**: Ensures the schema doesn't have types that don't exist in webhooks (or listed in `SCHEMA_ONLY` or `NAME_MAPPINGS`)
