Quasar compiles one Vue 3 codebase into SPA, PWA, SSR, Electron, Capacitor, and browser extension builds. Here's how the platform isolation model works and where it breaks.
Decide whether to ship ESM, CJS, UMD, or a combination from Vite library mode, see the trade-offs in a compact table, and follow a concrete build-and-validation workflow.
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 Vite exposes only VITE_ prefixed environment variables to client code via import.meta.env, with a worked example, limits, and common pitfalls.
Learn how to implement custom Hot Module Replacement (HMR) in Vite to prevent full page reloads and preserve application state during development.
Vite pre-bundles CommonJS dependencies with esbuild at startup to serve native ES modules instantly. Learn how the cache works, how to tune optimizeDeps, and the trade-offs for dev server speed.
Get a Vite dev server running, prove HMR actually works via the WebSocket check, and fix the common Docker/reverse-proxy cases where hot reload silently fails.
Vitest’s default watch mode launches a Vite dev server, giving tests instant HMR feedback without extra configuration.
Configure Vitest workers, reporters, aliases, and test.fixme so local runs stay fast and CI output stays deterministic and attributable.
