Webpack to Vite: Improving Speed and Performance

说明与用途

将项目从 Webpack 迁移到 Vite，将构建时间降至 5 秒以下，提升了 HMR 并简化了配置。

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 ~30–45 seconds to under 5 seconds, HMR became more responsive, and the configuration became easier to maintain.

工作流

• 1. Installed Vite and required plugins.
• 2. Replaced Webpack config with Vite config, mapping aliases and environment variables.
• 3. Updated npm scripts to use Vite dev and build commands.
• 4. Adjusted import paths and updated any Webpack‑specific loaders to Vite equivalents.
• 5. Ran tests and verified functionality.
• 6. Deployed the new build to production and monitored performance.

证据

We saw a dramatic drop in build times from 30–45 seconds to under 5 seconds after switching to Vite.
