rollup-plugin-install

0.0.5 verified Fri May 01 auth: no javascript deprecated

A Rollup/Vite plugin that automatically installs missing dependencies during the build process. Version 0.0.5 (stable, no recent updates) integrates into Vite or Rollup config and triggers npm/yarn install when an imported module is not found. Differentiator: eliminates manual install steps during development, but limited to simple use cases and may not handle edge cases like version conflicts. Alternative to manual dependency management or tools like pnpm.

Common errors

error Error: Cannot find module 'some-package' ↓

cause Plugin did not run because options misconfigured or plugin not applied correctly.

fix

Ensure autoInstallPlugin is in the plugins array and options.bin is set correctly (npm/yarn).

Warnings

gotcha Plugin only triggers on build, not in dev server's hot reload. ↓

fix Manually install dependencies before starting dev server.

deprecated Package has not been updated since 2020; use at your own risk. ↓

fix Consider using alternative solutions like pnpm or manual install steps.

Install

npm install rollup-plugin-install

yarn add rollup-plugin-install

pnpm add rollup-plugin-install

Imports

autoInstallPlugin

wrong

const { autoInstallPlugin } = require('rollup-plugin-install')

correct

import { autoInstallPlugin } from 'rollup-plugin-install'

ESM import is preferred; CJS require works but may have issues in strict ESM projects.

default import (autoInstallPlugin)
wrong
```
const autoInstallPlugin = require('rollup-plugin-install')
```
correct
```
import autoInstallPlugin from 'rollup-plugin-install'
```
Both named and default imports export the same function; default import is simpler.

Quickstart

Configures Vite to automatically install missing dependencies using npm.

// vite.config.js
import { defineConfig } from 'vite';
import { autoInstallPlugin } from 'rollup-plugin-install';

export default defineConfig({
  plugins: [
    autoInstallPlugin({ bin: 'npm' }),
  ],
});
