vite-node

Running Node.js scripts with ES modules

This feature allows you to run Node.js scripts that use ES module syntax, leveraging Vite's module resolution and transformation capabilities.

import { createServer } from 'vite-node/server';

const server = createServer({
  // Vite's options here
});

server.moduleGraph.ensureEntryFromUrl('/path/to/your/module.js');

Hot Module Replacement (HMR)

vite-node supports HMR, enabling developers to have a more interactive development experience by automatically reloading modules when changes are detected.

import { createServer } from 'vite-node/server';

const server = createServer({
  // Vite's options here
});

server.watcher.on('change', (file) => {
  server.moduleGraph.invalidateModule(file);
});

TypeScript support

With vite-node, you can run TypeScript files directly without pre-compilation, as it integrates with Vite's built-in TypeScript support.

import { createServer } from 'vite-node/server';

const server = createServer({
  // Vite's options here
});

server.moduleGraph.ensureEntryFromUrl('/path/to/your/typescript-module.ts');
