react-refresh-webpack-plugin

To ensure full support of “Fast Refresh” with components rendered by custom renderers, you should ensure the renderer you’re using depends on a recent version of react-reconciler.

We recommend version 0.25.0 or above, but any versions above 0.22.0 should work.

If the renderer is not compatible, please file them an issue instead.

TypeScript support is available out-of-the-box for those who use webpack.config.ts.

Our exported types however depends on type-fest, so you’ll have to add it as a devDependency:

# if you prefer npm
npm install -D type-fest

# if you prefer yarn
yarn add -D type-fest

# if you prefer pnpm
pnpm add -D type-fest

[email protected] only supports Node.js v16 or above, [email protected] only supports Node.js v14.16 or above, and [email protected] only supports Node.js v12.20 or above. If you’re using an older version of Node.js, please install [email protected].

const webpack = require('webpack');

const isDevelopment = process.env.NODE_ENV !== 'production';

module.exports = {
  mode: isDevelopment ? 'development' : 'production',
  plugins: [isDevelopment && new webpack.HotModuleReplacementPlugin()].filter(Boolean),
};

const { WebpackPluginServe } = require('webpack-plugin-serve');

const isDevelopment = process.env.NODE_ENV !== 'production';

module.exports = {
  mode: isDevelopment ? 'development' : 'production',
  plugins: [isDevelopment && new WebpackPluginServe()].filter(Boolean),
};

Install react-refresh-typescript. Ensure your TypeScript version is at least 4.0.

# if you prefer npm
npm install -D react-refresh-typescript

# if you prefer yarn
yarn add -D react-refresh-typescript

# if you prefer pnpm
pnpm add -D react-refresh-typescript

Then, instead of wiring up react-refresh/babel via babel-loader, you can wire-up react-refresh-typescript with ts-loader:

const ReactRefreshWebpackPlugin = require('@pmmmwh/react-refresh-webpack-plugin');
const ReactRefreshTypeScript = require('react-refresh-typescript');

const isDevelopment = process.env.NODE_ENV !== 'production';

module.exports = {
  mode: isDevelopment ? 'development' : 'production',
  module: {
    rules: [
      {
        test: /\.[jt]sx?$/,
        exclude: /node_modules/,
        use: [
          {
            loader: require.resolve('ts-loader'),
            options: {
              getCustomTransformers: () => ({
                before: [isDevelopment && ReactRefreshTypeScript()].filter(Boolean),
              }),
              transpileOnly: isDevelopment,
            },
          },
        ],
      },
    ],
  },
  plugins: [isDevelopment && new ReactRefreshWebpackPlugin()].filter(Boolean),
};

It is recommended to run ts-loader with transpileOnly is set to true. You can use ForkTsCheckerWebpackPlugin as an alternative if you need typechecking during development.

Ensure your @swc/core version is at least 1.2.86. It is also recommended to use swc-loader version 0.1.13 or above.

Then, instead of wiring up react-refresh/babel via babel-loader, you can wire-up swc-loader and use the refresh transform:

const ReactRefreshWebpackPlugin = require('@pmmmwh/react-refresh-webpack-plugin');

const isDevelopment = process.env.NODE_ENV !== 'production';

module.exports = {
  mode: isDevelopment ? 'development' : 'production',
  module: {
    rules: [
      {
        test: /\.[jt]sx?$/,
        exclude: /node_modules/,
        use: [
          {
            loader: require.resolve('swc-loader'),
            options: {
              jsc: {
                transform: {
                  react: {
                    development: isDevelopment,
                    refresh: isDevelopment,
                  },
                },
              },
            },
          },
        ],
      },
    ],
  },
  plugins: [isDevelopment && new ReactRefreshWebpackPlugin()].filter(Boolean),
};

Starting from version 0.1.13, swc-loader will set the development option based on Webpack’s mode option. swc won’t enable fast refresh when development is false.
