  • Build a Vite 5 backend integration with Flask
    11 projects | | 25 Feb 2024
    Unlike Webpack, the Vite DevServer only compiles files when they are requested. It leverages ES module imports, which allow JS files to import other files without needing to bundle them together during development. When one file changes, only that file needs to be re-compiled, and the rest can remain unchanged. Project files are compiled with Rollup.js. Third-party dependencies in node_modules are pre-compiled using the ultra-fast esbuild bundler for maximum speed, and they are cached until the dependency version changes. Vite also provides a client script for hot module reloading.

  • Why use Vite when Bun is also a bundler? - Vite vs. Bun

    For production, Vite can use another bundler, esbuild, to speed up transpilation and minification, while it in production also uses the bundler Rollup to create the client side JS bundle, due to Rollup's flexible API. Even though Vite uses ESM in development environment, for speed. In the future Vite may use esbuild entirely for bundling instead of Rollup, due to the speed it would gain.
