How does Vite achieve faster development server startup compared to traditional bundlers?

Vite achieves faster startup through several key strategies:

1. No bundling in development: Instead of bundling all files upfront, Vite serves source files directly using native ES modules
2. Dependency pre-bundling: Uses esbuild to pre-bundle dependencies (node_modules) into a single file, which only needs to happen once
3. On-demand compilation: Only compiles files when they're requested by the browser
4. Native ES modules: Leverages the browser's native module system, eliminating the need for complex bundling during development

This approach means the development server starts almost instantly, even for large applications.
