Supports [`node:` protocol imports](https://nodejs.org/dist/latest-v16.x/docs/api/esm.html#node-imports). ## Why do I need this? ``` Module "stream" has been externalized for browser compatibility. Cannot access "stream.Readable" in client code. ``` Since browsers do not support Node's [Core Modules](https://nodejs.org/dist/latest-v16.x/docs/api/modules.html#core-modules), packages that use them must be polyfilled to function in browser environments. In an attempt to prevent runtime errors, Vite produces [errors](https://github.com/vitejs/vite/issues/9200) or [warnings](https://github.com/vitejs/vite/pull/9837) when your code references builtin modules such as `fs` or `path`. ## Getting Started Install the package as a dev dependency. ```sh # npm npm install --save-dev vite-plugin-node-polyfills # pnpm pnpm install --save-dev vite-plugin-node-polyfills # yarn yarn add --dev vite-plugin-node-polyfills ``` Add the plugin to your `vite.config.ts` file. ```ts import { defineConfig } from 'vite' import { nodePolyfills } from 'vite-plugin-node-polyfills' // https://vitejs.dev/config/ export default defineConfig({ plugins: [ nodePolyfills(), ], }) ``` ### Customizable when you need it The following options are available to customize it for your needs. ```ts import { defineConfig } from 'vite' import { nodePolyfills } from 'vite-plugin-node-polyfills' // https://vitejs.dev/config/ export default defineConfig({ plugins: [ nodePolyfills({ // To add only specific polyfills, add them here. If no option is passed, adds all polyfills include: ['path'], // To exclude specific polyfills, add them to this list. Note: if include is provided, this has no effect exclude: [ 'http', // Excludes the polyfill for `http` and `node:http`. ], // Whether to polyfill specific globals. globals: { Buffer: true, // can also be 'build', 'dev', or false global: true, process: true, }, // Override the default polyfills for specific modules. overrides: { // Since `fs` is not supported in browsers, we can use the `memfs` package to polyfill it. fs: 'memfs', }, // Whether to polyfill `node:` protocol imports. protocolImports: true, }), ], }) ``` ### All polyfills - If protocolImports is true, also adds node:[module] ```js [ '_stream_duplex', '_stream_passthrough', '_stream_readable', '_stream_transform', '_stream_writable', 'assert', 'buffer', 'child_process', 'cluster', 'console', 'constants', 'crypto', 'dgram', 'dns', 'domain', 'events', 'fs', 'http', 'http2', 'https', 'module', 'net', 'os', 'path', 'process', 'punycode', 'querystring', 'readline', 'repl', 'stream', 'string_decoder', 'sys', 'timers', 'timers/promises', 'tls', 'tty', 'url', 'util', 'vm', 'zlib', ] ``` ## About the author Hello!
