Vite-Plugin-Nodemon

Run a backend server in a Vite project via Nodemon.

Usage

Install the plugin as you would any other Vite plugin:

In vite.config.js:

import {defineConfig} from 'vite';

export default defineConfig({
  plugins: [
    pluginNodemon({
      script: './server.js',
      watch: [
        '.env',
        'package.json',
        'server.js',
        'src/' + '**' + '/*.js', // Watch all JS files (we split the string up like this because those charcaters together can sometimes upset linters)
      ],
      ignore: [
        'src/main.js', // Ignore the Vite main file
      ],
      envInject: { // Inject these environment variables into both Vite + the process
      },
      envInjectVite: { // Inject these environment variables into Vite
        VITE_API_URL_BASE: 'http://localhost:8080',
      },
      envInjectProcess: { // Inject these environment variables into the process
        SERVER_HOST: 'localhost',
        SERVER_PORT: 8080,
      },
    }),
  ],
});
