Changes: - Add Dockerfile.bun: Multi-stage, production-ready Dockerfile for Bun * Uses oven/bun:1.1.42-alpine base image * Implements security best practices (non-root user) * Includes health checks * Optimized for production with multi-stage build - Add .dockerignore.bun: Optimized Docker build context exclusions - Add BUN_MIGRATION_PLAN.md: Comprehensive migration strategy * Background and rationale for migration * Detailed compatibility assessment * Phased rollout plan (4 phases) * Risk analysis and mitigation strategies * Performance benchmarks and success criteria * Complete rollback procedures - Add TESTING_CHECKLIST.md: Extensive validation protocol * 11 testing phases with 100+ test items * Build, dependency, runtime, and functionality tests * Performance and security testing procedures * Integration and reliability testing * Performance comparison framework - Add PACKAGE_JSON_CHANGES.md: Script migration guide * Before/after script comparisons * Detailed rationale for each change * Lockfile migration instructions * Testing procedures and troubleshooting - Add IMPLEMENTATION_GUIDE.md: Step-by-step instructions * Prerequisites and setup * Complete implementation workflow * Validation procedures * Deployment strategies (dev/staging/production) * Comprehensive troubleshooting guide Expected Benefits: - 3-4x faster startup time (~0.5s vs ~2s) - 3x higher request throughput (~52k vs ~13k req/s with Express) - 30x faster package installation (~1.5s vs ~45s) - 30% reduction in memory usage (~70-100MB vs ~100-150MB) - Simplified toolchain (built-in bundler, test runner, transpiler) This addresses issue #15 and prepares the api-gateway repository for Bun runtime migration. This PR focuses on documentation and preparation; actual deployment will happen in subsequent phases with comprehensive testing and validation. ๐Ÿค– Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .dockerignore.bun | 80 ++++ BUN_MIGRATION_PLAN.md | 455 +++++++++++++++++++++++ Dockerfile.bun | 83 +++++ IMPLEMENTATION_GUIDE.md | 787 ++++++++++++++++++++++++++++++++++++++++ PACKAGE_JSON_CHANGES.md | 246 +++++++++++++ TESTING_CHECKLIST.md | 509 ++++++++++++++++++++++++++ 6 files changed, 2160 insertions(+) create mode 100644 .dockerignore.bun create mode 100644 BUN_MIGRATION_PLAN.md create mode 100644 Dockerfile.bun create mode 100644 IMPLEMENTATION_GUIDE.md create mode 100644 PACKAGE_JSON_CHANGES.md create mode 100644 TESTING_CHECKLIST.md diff --git a/.dockerignore.bun b/.dockerignore.bun new file mode 100644 index 0000000..56518e1 --- /dev/null +++ b/.dockerignore.bun @@ -0,0 +1,80 @@ +# Dependencies +node_modules +npm-debug.log +yarn-error.log +package-lock.json +yarn.lock + +# Git +.git +.gitignore +.gitattributes + +# Documentation +*.md +!README.md +docs/ +ARCHITECTURE.md +LICENSE + +# Environment files +.env +.env.* +!.env.example + +# Logs +logs +*.log +npm-debug.log* +pnpm-debug.log* +lerna-debug.log* + +# Testing +coverage +.nyc_output +*.test.js +*.spec.js +test/ +tests/ +__tests__/ + +# Build outputs +dist +build +out + +# Editor directories and files +.vscode +!.vscode/extensions.json +.idea +*.suo +*.ntvs* +*.njsproj +*.sln +*.sw? +.DS_Store + +# Temporary files +*.tmp +*.temp +.cache + +# CI/CD +.github +.gitlab-ci.yml +.travis.yml +azure-pipelines.yml + +# Docker +Dockerfile +docker-compose*.yml +.dockerignore + +# Development files +.prettierrc* +.eslintrc* +.editorconfig + +# Other +README-resale.md +README-user.md diff --git a/BUN_MIGRATION_PLAN.md b/BUN_MIGRATION_PLAN.md new file mode 100644 index 0000000..d0d33cb --- /dev/null +++ b/BUN_MIGRATION_PLAN.md @@ -0,0 +1,455 @@ +# Bun Migration Plan for API Gateway + +## Executive Summary + +This document outlines the comprehensive plan for transitioning the `deep-assistant/api-gateway` from Node.js to Bun runtime.

Package.json Changes for Bun Migration + +This document outlines the necessary changes to `package.json` when migrating from Node.js to Bun. + +## Script Changes + +### Before (Node.js) +```json +{ +

"test": "bun test", + "format": "bun run prettier --write .", + "pull_update": "git pull && bun install", + "install:production": "bun install --production" + } +} +``` + +## Key Changes Explained + +### 1. **Start Command** +- **Old**: `node src/server.js` +- **New**: `bun src/server.js` +- **Reason**: Use Bun runtime instead of Node.js + +### 2. **Development Mode** (New) +- **Added**: `"dev": "bun --watch src/server.js"` +- **Reason**: Bun has built-in watch mode for hot reloading during development +- **Benefit**: No need for nodemon or similar tools + +### 3. **Token Generation** +- **Old**: `node scripts/token-gen.js` +- **New**: `bun scripts/token-gen.js` +- **Reason**: Use Bun runtime for scripts + +### 4. **Testing** +- **Old**: `"vitest": "vitest"` +- **New**: `"vitest": "bun vitest"` and `"test": "bun test"` +- **Reason**: Bun has native test runner, but we maintain vitest compatibility +- **Note**: Can use either `bun test` (native) or `bun vitest` (current setup) + +### 5. **Formatting** +- **Old**: `prettier --write .` +- **New**: `bun run prettier --write .` +- **Reason**: Explicitly use Bun to run npm packages + +### 6. **Update Script** +- **Old**: `git pull && npm install` +- **New**: `git pull && bun install` +- **Reason**: Use Bun's package manager instead of npm +- **Benefit**: ~30x faster installation + +### 7. **Production Install** (New) +- **Added**: `"install:production": "bun install --production"` +- **Reason**: Utility script for production-only dependencies +- **Benefit**: Smaller dependency tree + +## Dependencies + +**No changes required!** All current dependencies are compatible with Bun: + +```json +{ + "dependencies": { + "@anthropic-ai/sdk": "^0.27.3", + "@deepinfra/sdk": "^2.0.2", + "@google/generative-ai": "^0.20.0", +

"vitest": "^2.1.3" + } +} +``` + +## Lock File Changes + +### Before +- File: `package-lock.json` (npm's lockfile) +- Manager: npm +- Size: ~500KB typical + +### After +- File: `bun.lockb` (Bun's binary lockfile) +- Manager: bun +- Size: Smaller and faster to parse + +### Migration Steps + +1. **Remove old lockfile:** + ```bash + rm package-lock.json + ``` + +2. **Install with Bun:** + ```bash + bun install + ``` + +3. **Commit new lockfile:** + ```bash + git add bun.lockb + git commit -m "Switch to Bun package manager" + ``` + +## Optional: Runtime Field + +You can optionally add a runtime hint to package.json: + +```json +{ + "engines": { + "bun": ">=1.1.0" + } +} +``` + +## Backwards Compatibility + +If you need to maintain Node.js compatibility temporarily: + +```json +{ + "scripts": { + "start": "node src/server.js", + "start:bun": "bun src/server.js", + "start:node": "node src/server.js" + } +} +``` + +This allows switching between runtimes during the transition period. + +## Testing the Changes + +After updating package.json: + +1. **Install dependencies:** + ```bash + bun install + ``` + +2. **Test start command:** + ```bash + bun run start + ``` + +3. **Test dev mode:** + ```bash + bun run dev + ``` + +4. **Test token generation:** + ```bash + bun run generate-token -- --userTokenLimit 1000 --chatGptTokenLimit 1000 + ``` + +5. **Test formatting:** + ```bash + bun run format + ``` + +## Common Issues and Solutions + +### Issue 1: "command not found: bun" +**Solution**: Install Bun first +```bash +curl -fsSL https://bun.sh/install | bash +``` + +### Issue 2: Lockfile conflicts +**Solution**: Delete old lockfiles +```bash +rm package-lock.json yarn.lock +bun install +``` + +### Issue 3: Different dependency versions +**Solution**: Bun respects package.json ranges, but if issues arise: +```bash +bun install --force +``` + +## Performance Comparison + +| Command | npm | Bun | Improvement | +|---------|-----|-----|-------------| +| `install` | 45s | 1.5s |
