vite-plugin-node-polyfills

• fix: Make sure all modules under buffer are exported

• Fix global polyfill import error (#74)

• Add end-to-end tests with Playwright
• Add unit/integration tests with Vitest
• Fix imports for global polyfills (buffer and process) when a trailing slash is used (e.g. import process from 'process/')
• Replace the IIFE banner with import statements (avoids name conflicts)

• Improve the shim process so that polyfilled globals are not statically replaced in libraries (#47).
• Internalize buffer and process shims so that conflicting install versions are no longer a concern with Yarn v1 (#61).

• Add support for Vite v5 (and make it the default)
• Configure CI to run checks on PRs and commits to main

• Reduce the package size by removing unnecessary files
• Correctly call the preconfigured onwarn handler when available

• Ensure the predefined onwarn handler is invoked if it exists
• Use env.command instead of env.mode so that alternative modes work properly

Add support for overriding default polyfills

Add the include option to only polyfill the specified modules. Thanks @leticiavna for the PR!

• Add a workaround for a Yarn v1 bug

v0.11.2

• Make sure globals (Buffer, global, and process) are properly shimmed in all environments.
• Replace upstream global shims with newer dependencies

Allow globals (Buffer, global, and process) to be disabled for build, dev, or both.

import { defineConfig } from 'vite'
import { nodePolyfills } from 'vite-plugin-node-polyfills'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    nodePolyfills({
      // Whether to polyfill specific globals.
      globals: {
        Buffer: 'dev', // defaults to true
        global: false, // defaults to true
        process: 'build', // defaults to true
      },
    }),
  ],
})

Update usage examples
