39_To be enriched in Phase 1B with deep code analysis_
39### GitHub Actions Workflows
40
41This repository provides shared GitHub Actions for **package maintainers** building native modules across multiple platforms.
42
43**Available Actions:**
44
45#### 1. compile-prebuilds
46
47Compiles native addons for specific platform/architecture combinations.
48
49**Inputs:**
50- `platform` (required) - Target platform: `linux`, `darwin`, `win32`, `android`, `ios`
51- `arch` (required) - Target architecture: `x64`, `arm64`, `arm`, `ia32`
52- `flags` (optional) - Additional build system flags
53- `tags` (optional) - Additional tags for uploaded prebuilds
54- `upload` (optional) - Upload compiled prebuilds (default: `false`)
55
56**Process:**
571. Installs `bare-make` globally
582. Generates build files for platform/arch
593. Compiles with `bare-make build`
604. Installs artifacts locally
615. Optionally uploads via `upload-prebuilds` action
62
63**Example Usage:**
64```yaml
65name: Build Prebuilds
66
67on: push

187 with:
188 platform: ${{ matrix.platform }}
189 arch: ${{ matrix.arch }}
190```
191
192**Use Case:** Reduce build time by targeting only necessary platforms.
193
194### Example 3: Custom Build Flags
195
196```yaml
197jobs:
198 build:
199 uses: holepunchto/actions/.github/workflows/compile-prebuilds.yml@v1
200 with:

202 arch: x64
203 flags: --debug # Custom bare-make flags
204 tags: debug,nightly
205```
206
207## Package Size Impact
208
209**Why This Matters for App Developers:**
210
211When you `npm install` packages like `sodium-native`, `bare-tls`, or `hyperswarm`, you download **all 13 platform prebuilds** that were created using these GitHub Actions.
212
213**Size Breakdown:**
214- Each native module: ~1-2 MB per platform × 13 platforms = 13-26 MB
215- Typical app with 20+ native modules: 260-520 MB
216- **After platform-specific pruning:** 20-40 MB
217
218**Optimization Strategy:**
219
2201. **Package Maintainers (using these actions):** Build all 13 platforms for maximum compatibility
221
2222. **App Developers (using the packages):** Prune to single platform before deployment
223
224```bash
225# Remove 12 other platforms before pear stage
226node prune-prebuilds.js
227pear stage myapp .
228# Result: 82% size reduction
229```
230
231See: [pear](../pear/skills.md) and [pear-pack](../pear-pack/skills.md) for optimization guides.
232
233## Workflow Comparison
234
235**For Package Maintainers:**
236```
237Code → holepunchto/actions → Build 13 platforms → Publish to npm
238```
239
240**For App Developers:**
241```
242npm install → Download all platforms → Prune to 1 platform → pear stage → Deploy
243```

54### `bundle(opts) -> Buffer`
55
56Generates a bare-bundle from a Pear application entrypoint.
57
58**Options:**
59- `cache` - Enable caching (default: `false`)
60- `prebuilds` - Path to prebuilds directory
61- `entry` - Application entrypoint (default: `/boot.js`)
62- `builtins` - Array of builtin modules
63
64**Returns:** Buffer containing bundled application

58_To be added in Phase 1B_
68### Example 1: Basic Bundle Generation
69
70```javascript
71import bundle from 'pear-bundle'
72
73const opts = {
74 cache: false,
75 prebuilds: 'path/to/prebuilds',

77 builtins: []
78}
79
80const packed = await bundle(opts)
81console.log('Bundle size:', packed.length)
82```
83
84### Example 2: Cached Bundle Build
85
86```javascript
87const packed = await bundle({
88 cache: true, // Reuse previous build artifacts
89 entry: '/index.js'
90})
91```
92
93**Use Case:** Speed up repeated builds during development.
94
95### Example 3: Custom Builtins
96
97```javascript
98const packed = await bundle({
99 entry: '/boot.js',
100 builtins: ['hypercore', 'hyperswarm'] // Pre-bundle these modules
101})
102```
103
104## Bare-Bundle Format
105
106Pear-bundle generates **bare-bundle** format, inspired by Electron's ASAR:
107
108**Benefits:**
109- Single-file distribution
110- Fast module resolution
111- Potential compression (unexplored)
112- Content-addressable modules
113
114**Format:** Per [bare-bundle](https://github.com/holepunchto/bare-bundle) specification.
115
116## Optimization Potential (Unexplored)
117
118**Theory:** bare-bundle format might provide additional compression beyond file-level optimization.
119
120**Comparison:**
121
122| Approach | JavaScript Size | Notes |
123|----------|-----------------|-------|
124| Raw files | ~6 MB | Individual .js files |
125| bare-bundle | ~6 MB | Single bundle file |
126| bare-bundle + compression | ??? | Not tested |
127
128**Status:** Compression potential not yet tested in production. Manual prebuild pruning achieves 82% size reduction - bare-bundle compression might provide additional 10-20% JavaScript savings.
129
130**Worth Exploring:** For production deployments where every MB matters.
131
132## Integration with pear-pack
133
134pear-bundle focuses on **JavaScript bundling**, while pear-pack handles both:
135- JavaScript bundling (via pear-bundle internally)
136- Prebuild management (native modules)
137
138**Workflow:**
139```
140pear-bundle → JavaScript bundle
141pear-pack → JavaScript bundle + filtered prebuilds
142pear stage → Upload to DHT (uses pear-pack internally)

58_To be enriched in Phase 1B with deep code analysis_
58### `pearPack(drive, opts) -> { bundle, prebuilds }`
59
60Creates a bundle buffer and Map of prebuild buffers from a Pear application.
61
62**Options:**
63
64- `target` - Target host architecture(s), may be single value or array
65 - Examples: `'linux-x64'`, `['linux-x64', 'darwin-arm64']`
66 - **Use this to filter prebuilds to specific platforms!**
67- `builtins` - Array of builtin modules to include
68- `entry` - Bundle entrypoint (default: `/boot.js`)
69- `conditionals` - Additional prefixed conditionals (default: `['node', 'bare']`)
70- `extensions` - Supported addon extensions (default: `['.node', '.bare']`)
71
72**Returns:**
73```javascript
74{
75 bundle: Buffer, // Bundled JavaScript code
76 prebuilds: Map<key, Buffer> // Platform-specific native modules
77}
78```

6080## Usage Examples
6181
62_To be added in Phase 1B_
82### Example 1: Platform-Specific Bundle
83
84```javascript
85import pearPack from 'pear-pack'
86import Localdrive from 'localdrive'
87
88const drive = new Localdrive('./myapp')
89
90// Create linux-x64 specific bundle
91const { bundle, prebuilds } = await pearPack(drive, {
92 target: 'linux-x64', // Only include linux-x64 prebuilds
93 entry: '/index.js'
94})
95
96console.log('Bundle size:', bundle.length)
97console.log('Prebuilds:', prebuilds.size)
98```
99
100**Use Case:** Build platform-specific distributions programmatically instead of manual prebuild pruning.
101
102### Example 2: Multi-Platform Bundle
103
104```javascript
105// Create bundle for multiple platforms
106const { bundle, prebuilds } = await pearPack(drive, {
107 target: ['linux-x64', 'darwin-arm64', 'win32-x64'],
108 entry: '/index.js'
109})
110
111// This includes prebuilds for Linux, macOS M1/M2, and Windows
112```
113
114**Use Case:** Create universal bundles for specific platform combinations.
115
116### Example 3: Minimal Bundle (No Prebuilds)
117
118```javascript
119// Bundle without any native modules (smallest size)
120const { bundle, prebuilds } = await pearPack(drive, {
121 target: [], // No platform-specific prebuilds
122 entry: '/index.js'
123})
124
125// App must handle missing native modules gracefully
126```
127
128**Use Case:** Distribute minimal JavaScript-only bundle, download natives on-demand at runtime.
129
130## Package Size Optimization
131
132**Problem:** Native module prebuilds bloat package size from ~10 MB → 300+ MB
133
134**Solutions:**
135
136### 1. Use `target` Option (Programmatic)
137
138```javascript
139const opts = {
140 target: process.platform + '-' + process.arch, // Current platform only
141 entry: '/index.js'
142}
143
144const packed = await pearPack(drive, opts)
145// Result: ~50-60 MB for single platform
146```
147
148### 2. Manual Prebuild Pruning (Alternative)
149
150If not using pear-pack programmatically, use a pruning script before `pear stage`:
151
152```bash
153npm run prune # Remove other platform prebuilds
154pear stage myapp .
155```
156
157See: [pear skills](../pear/skills.md) for complete pruning script.
158
159## Performance Comparison
160
161| Method | Size (Linux x64) | Platforms | Notes |
162|--------|------------------|-----------|-------|
163| All prebuilds | 304 MB | 13 | Default npm install |
164| `target: 'linux-x64'` | ~53 MB | 1 | pear-pack filtering |
165| Manual pruning | ~53 MB | 1 | Equivalent to target option |
166| No prebuilds | ~13 MB | 0 | Runtime download needed |
167
168**Recommendation:** Use `target` option when building programmatically, or manual pruning for CLI workflows.

177### Problem: Native Module Prebuilds
178
179Pear apps using native modules (hypercore, hyperswarm, etc.) include prebuilds for **13 platforms**:
180- Android: arm, arm64, ia32, x64
181- iOS: arm64, arm64-simulator, x64-simulator
182- macOS: arm64 (M1/M2), x64 (Intel)
183- Linux: arm64, x64
184- Windows: arm64, x64
185
186**Impact:** A typical app grows from ~10 MB to 300+ MB with all platform binaries.
187
188### Solution: Platform-Specific Pruning
189
190**Script:** Remove prebuilds for platforms you don't need before staging.
164191
165192```javascript
193#!/usr/bin/env node
194const fs = require('fs')
195const path = require('path')
196const os = require('os')
197
198const currentPlatform = `${os.platform()}-${os.arch()}`
199
200function prunePrebuilds(dir, depth = 0) {
201 if (depth > 10) return
202
203 const entries = fs.readdirSync(dir, { withFileTypes: true })
204
205 for (const entry of entries) {
206 const fullPath = path.join(dir, entry.name)
207
208 if (!entry.isDirectory()) continue
209
210 if (entry.name === 'prebuilds') {
211 // Remove other platform prebuilds
212 const platforms = fs.readdirSync(fullPath)
213 for (const platform of platforms) {
214 if (platform !== currentPlatform) {
215 fs.rmSync(path.join(fullPath, platform), { recursive: true })
216 }
217 }
218 } else if (entry.name === 'node_modules') {
219 prunePrebuilds(fullPath, depth + 1)
220 } else if (entry.name.startsWith('@')) {
221 // Scoped package namespace
222 prunePrebuilds(fullPath, depth)
223 } else {
224 // Check for nested node_modules
225 const nested = path.join(fullPath, 'node_modules')
226 if (fs.existsSync(nested)) {
227 prunePrebuilds(nested, depth + 1)
228 }
229 }
230 }
231}
232
233prunePrebuilds('./node_modules')
234```
166235
236**Results:** 82-85% size reduction (300 MB → 50-60 MB)
237
238**Integration:**
239```json
240{
241 "scripts": {
242 "prune": "node prune-prebuilds.js",
243 "stage": "npm run prune && pear stage myapp ."
244 }

277```
278
279**Note:** Never ignore `node_modules` entirely - module resolution under `pear://` protocol requires it.
