Vite inlines VITE_-prefixed variables into the browser bundle at build time. This note covers a minimal design that keeps secrets in Node-side config, operational checks to prevent leaks, and failure modes to avoid.
Vite pre-bundles your dependencies with esbuild at dev-server startup, turning hundreds of module requests into one per package. Here's how it works, how to verify it, and when to tune optimizeDeps.
Vite’s Hot Module Replacement uses native ES modules to update only changed parts of an app, preserving state with React Fast Refresh. See a concrete example, how to use <code>import.meta.hot</code>, and common pitfalls.
Learn how to use the import.meta.hot API in Vite to create HMR boundaries, prevent full page reloads, and properly clean up side effects during development.
Learn how Vite automatically treats files ending in .module.css (and variants) as CSS Modules, how to import them, tweak the hash format, and what to watch out for when mixing global and module styles.
Vite's SWC-based React plugin replaces Babel with a Rust compiler for faster JSX transforms. Here's the migration, how to measure the gain on your own codebase, and the Babel-plugin trade-offs that decide whether it's worth it.
Vite serves source as native ES modules, eliminating dev-time bundling. HMR updates only the changed module chain, preserving state. Trade-off: first-run dependency pre-bundling can be slow for large projects.
Vite speeds up dev server startup by pre‑bundling node_modules with esbuild, caching the result, and letting you control the process via optimizeDeps. Learn how it works, its limits, and practical checks.
A concise diagnostic guide for Vite environment variable handling: identify missing variables, root causes, ordered checks, fixes, and escalation criteria.
