3. Follow the specific instructions in that example file for syntax, structure, and best practices

   Important Notes:

   • Rspack is compatible with most Webpack plugins and loaders
   • Configuration format is similar to Webpack
   • Rspack provides better performance than Webpack
   • Examples include both JavaScript and TypeScript versions
   • Each example file includes parameters, returns, common errors, best practices, and scenarios

4. Reference the official documentation when needed:

   • Guide: https://rspack.rs/zh/guide/
   • Configuration: https://rspack.rs/zh/config/
   • Plugins: https://rspack.rs/zh/plugins/
   • API: https://rspack.rs/zh/api/

Best Practices

1. Use TypeScript for configuration: Better type safety and autocomplete
2. Leverage built-in plugins: Use Rspack plugins when available
3. Optimize for production: Use production mode for builds
4. Code splitting: Use optimization.splitChunks for better performance
5. Cache configuration: Enable persistent caching for faster rebuilds
6. Use HMR: Enable Hot Module Replacement for better DX

能力边界

✅ 适用场景

• 当你需要使用此技能对应的技术栈时
• 当项目需要遵循最佳实践时
• 当需要快速上手或深入理解核心概念时

⚠️ 需要注意

• 复杂业务逻辑需要结合具体场景调整
• 性能优化需要根据实际数据量评估

❌ 不适用场景

• 不相关的技术栈或框架
• 需要完全自定义的特殊场景

常见陷阱 (Gotchas)

1. 版本兼容性：注意框架版本与依赖库的兼容性，不同版本 API 可能有差异
2. 配置文件格式：配置文件格式错误是最常见的问题，建议使用编辑器的语法检查
3. 环境变量：确保所有必要的环境变量已正确设置，敏感信息不要硬编码
4. 依赖冲突：多版本共存时注意依赖冲突，使用 lock 文件锁定版本
5. 性能陷阱：大数据量场景下注意性能优化，避免 N+1 查询等常见问题

使用流程

Step 1: 环境准备

确保开发环境已安装必要的依赖和工具。

Step 2: 配置初始化

根据项目需求进行基础配置。

Step 3: 核心功能使用

按照示例代码实现核心功能。

Step 4: 测试验证

运行测试确保功能正常。

Step 5: 部署上线

完成开发后进行部署和监控。
