vite-plugin-externalise-dependencies

A Vite plugin that automatically externalizes all packages listed in the dependencies field of your package.json file. Useful for building libraries that should not bundle their dependencies such as server side / node packages.

Installation

npm install @itxch/vite-plugin-externalise-dependencies --save-dev

Usage

Add the plugin to your vite.config.ts:

import { defineConfig } from "vite";
import externaliseDependencies from "@itxch/vite-plugin-externalise-dependencies";

export default defineConfig({
  plugins: [externaliseDependencies()],
});

How It Works

The plugin reads your project's package.json file and automatically adds all packages listed in the dependencies field to Vite's external configuration. This is useful when:

• Building libraries that should not bundle their dependencies
• Creating packages that rely on peer dependencies
• Reducing bundle size by excluding dependencies

Options

| Option | Type | Default | Description | | ----------------- | -------- | --------------------- | ------------------------------------- | | packageJsonPath | string | {root}/package.json | Custom path to your package.json file |

Requirements

• Node.js >= 22
• Vite >= 5
