Usage Examples
Prompt Template
Act as an expert in Bun runtime. Provide a step-by-step migration plan for moving a [PROJECT_NAME] from Node.js to Bun in [COMPANY_NAME]'s [INDUSTRY] environment. Include commands to test compatibility with [DATA_TYPE] like APIs, databases, or CLI tools. Use the latest Bun version [BUN_VERSION] and assume [DEPENDENCIES] are listed in package.json. Start with a compatibility check and end with performance benchmarks.
Example Output
# Bun Migration Guide for Acme Corp's E-commerce API ## 1. Compatibility Check ```bash bun init -y bun add [email protected] bunx @bun-compat/check package.json ``` **Results:** - ✅ Express: 4.18.2 → Compatible (v1.0.24+) - ⚠️ Knex.js: 2.5.1 → Needs adapter (use `bun:sqlite`) - ❌ Sharp: 0.32.6 → Replace with `bun:sharp` ## 2. Dependency Updates ```bash # Replace incompatible packages bun add bun:sqlite knex bun add bun:sharp sharp ``` ## 3. Code Adjustments ```javascript // Before (Node.js) const fs = require('fs'); // After (Bun) import { readFileSync } from 'fs'; ``` ## 4. Performance Benchmark (vs Node.js 20) ``` # API Response Time (1000 requests) Node.js: 1245ms Bun: 789ms (37% faster) # Memory Usage Node.js: 180MB Bun: 110MB ``` ## 5. Deployment Notes - Use `bun run` instead of `node` - Replace `npm ci` with `bun install --frozen-lockfile` - Add `.bunfig.toml` for optimized settings: ```toml [install] strict_peer_deps = true ```
