Webpack to Vite: Improving Speed and Performance

说明与用途

将项目从 Webpack 迁移到 Vite，将构建时间缩短到 5 秒以下，提升 HMR 速度并简化配置。

问题

The team’s build times were slow and the development experience was cumbersome due to Webpack’s complexity and long rebuilds.

结果

Build times dropped from 30–60 seconds to under 5 seconds, HMR became instant, and the configuration became a single file. Development speed and overall productivity improved noticeably.

工作流

• 1. Audit current Webpack setup and identify plugins and loaders.
• 2. Install Vite and necessary adapters (e.g., @vitejs/plugin-react).
• 3. Replace Webpack config with Vite config, mapping entry points and aliases.
• 4. Migrate environment variables and asset handling to Vite conventions.
• 5. Update scripts in package.json to use Vite dev and build commands.
• 6. Test the application locally, ensuring HMR and routing work.
• 7. Run CI pipeline to verify build and test passes.
• 8. Deploy to production and monitor performance metrics.

证据

We reduced our build times from 30–60 seconds to under 5 seconds.
