## 1. What is Vite and what is its main advantage in development?

**Answer**

Vite is a modern build tool that uses the browser's native ES modules in development, eliminating the need for bundling and enabling near-instant Hot Module Replacement. Unlike Webpack which bundles all code at startup, Vite only compiles files on demand. This approach drastically reduces startup time for Vue and Nuxt projects, especially on large codebases.

## 2. Which bundler does Vite use for production?

**Answer**

Vite uses Rollup for production bundling. This choice leverages Rollup's mature plugin ecosystem and advanced optimizations like efficient tree-shaking and automatic code splitting. In development, Vite uses esbuild for fast transpilation, but in production, Rollup provides better control over optimized bundle generation.

## 3. How to configure custom path aliases in a Vite project with Vue?

**Answer**

Path aliases are configured in the vite.config.ts file via the resolve.alias property. This configuration allows defining shortcuts like @ to point to the src folder, avoiding complex relative imports. It is also necessary to synchronize this configuration with tsconfig.json so TypeScript recognizes these aliases and provides correct autocompletion in the editor.
