|
An **EXPERIMENTAL** Webpack plugin to enable "Fast Refresh" (also known as _Hot Reloading_) for React components.
|
||
|
|
||
|
> This plugin is not 100% stable.
|
||
|
> We're hoping to land a v1 release soon - please help us by reporting any issues you've encountered!
|
||
|
|
||
|
## Getting Started
|
||
|
|
||
|
### Prerequisites
|
||
|
|
||
|
Ensure that you are using at least the minimum supported versions of this plugin's peer dependencies -
|
||
|
older versions unfortunately do not contain code to orchestrate "Fast Refresh",
|
||
|
and thus cannot be made compatible.
|
||
|
|
||
|
We recommend using the following versions:
|
||
|
|
||
|
| Dependency | Version |
|
||
|
| --------------- | ---------------------------- |
|
||
|
| `react` | `16.13.0`+, `17.x` or `18.x` |
|
||
|
| `react-dom` | `16.13.0`+, `17.x` or `18.x` |
|
||
|
| `react-refresh` | `0.10.0`+ |
|
||
|
| `webpack` | `4.46.0`+ or `5.2.0`+ |
|
||
|
|
||
|
<details>
|
||
|
<summary>Minimum requirements</summary>
|
||
|
<br />
|
||
|
|
||
|
| Dependency | Version |
|
||
|
| --------------- | -------- |
|
||
|
| `react` | `16.9.0` |
|
||
|
| `react-dom` | `16.9.0` |
|
||
|
| `react-refresh` | `0.10.0` |
|
||
|
| `webpack` | `4.43.0` |
|
||
|
|
||
|
</details>
|
||
|
|
||
|
<details>
|
||
|
<summary>Using custom renderers (e.g. <code>react-three-fiber</code>, <code>react-pdf</code>, <code>ink</code>)</summary>
|
||
|
<br />
|
||
|
|
||
|
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.
|
||
|
|
||
|
</details>
|
||
|
|
||
|
### Installation
|
||
|
|
||
|
With all prerequisites met, you can install this plugin using your package manager of choice:
|
||
|
|
||
|
```sh
|
||
|
# if you prefer npm
|
||
|
npm install -D @pmmmwh/react-refresh-webpack-plugin react-refresh
|
||
|
|
||
|
# if you prefer yarn
|
||
|
yarn add -D @pmmmwh/react-refresh-webpack-plugin react-refresh
|
||
|
|
||
|
# if you prefer pnpm
|
||
|
pnpm add -D @pmmmwh/react-refresh-webpack-plugin react-refresh
|
||
|
```
|
||
|
|
||
|
The `react-refresh` package (from the React team) is a required peer dependency of this plugin.
|
||
|
We recommend using version `0.10.0` or above.
|
||
|
|
||
|
<details>
|
||
|
<summary>Support for TypeScript</summary>
|
||
|
<br />
|
||
|
|
||
|
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`:
|
||
|
|
||
|
```sh
|
||
|
# 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
|
||
|
```
|
||
|
|
||
|
> **:memo: Note**:
|
||
|
>
|
||
|
> `type-fest@2.x` only supports Node.js v12.20 or above.
|
||
|
> If you're using an older version of Node.js, please install `type-fest@1.x`.
|
||
|
|
||
|
</details>
|
||
|
|
||
|
### Usage
|
||
|
|
||
|
For most setups, we recommend integrating with `babel-loader`.
|
||
|
It covers the most use cases and is officially supported by the React team.
|
||
|
|
||
|
The example below will assume you're using `webpack-dev-server`.
|
||
|
|
||
|
If you haven't done so, set up your development Webpack configuration for Hot Module Replacement (HMR).
|
||
|
|
||
|
```js
|
||
|
const isDevelopment = process.env.NODE_ENV !== 'production';
|
||
|
|
||
|
module.exports = {
|
||
|
mode: isDevelopment ? 'development' : 'production',
|
||
|
devServer: {
|
||
|
hot: true,
|
||
|
},
|
||
|
};
|
||
|
```
|
||
|
|
||
|
<details>
|
||
|
<summary>Using <code>webpack-hot-middleware</code></summary>
|
||
|
<br />
|
||
|
|
||
|
```js
|
||
|
const webpack = require('webpack');
|
||
|
|
||
|
const isDevelopment = process.env.NODE_ENV !== 'production';
|
||
|
|
||
|
module.exports = {
|
||
|
mode: isDevelopment ? 'development' : 'production',
|
||
|
plugins: [isDevelopment && new webpack.HotModuleReplacementPlugin()].filter(Boolean),
|
||
|
};
|
||
|
```
|
||
|
|
||
|
</details>
|
||
|
|
||
|
<details>
|
||
|
<summary>Using <code>webpack-plugin-serve</code></summary>
|
||
|
<br />
|
||
|
|
||
|
```js
|
||
|
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),
|
||
|
};
|
||
|
```
|
||
|
|
||
|
</details>
|
||
|
|
||
|
Then, add the `react-refresh/babel` plugin to your Babel configuration and this plugin to your Webpack configuration.
|
||
|
|
||
|
```js
|
||
|
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('babel-loader'),
|
||
|
options: {
|
||
|
plugins: [isDevelopment && require.resolve('react-refresh/babel')].filter(Boolean),
|
||
|
},
|
||
|
},
|
||
|
],
|
||
|
},
|
||
|
],
|
||
|
},
|
||
|
plugins: [isDevelopment && new ReactRefreshWebpackPlugin()].filter(Boolean),
|
||
|
};
|
||
|
```
|
||
|
|
||
|
> **:memo: Note**:
|
||
|
>
|
||
|
> Ensure both the Babel transform (`react-refresh/babel`) and this plugin are enabled only in `development` mode!

|
|
||
|

|
||
|
|
||
|
Install [`react-refresh-typescript`](https://github.com/Jack-Works/react-refresh-transformer/tree/main/typescript).
|
||
|
Ensure your TypeScript version is at least 4.0.
|
||
|
|
||
|
```sh
|
||
|
# 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`:
|
||
|
|
||
|
```js
|
||
|
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),
|
||
|
};
|
||
|
```
|
||
|
|
||
|
> `ts-loader` won't work with HMR unless `transpileOnly` is set to `true`.
|
||
|
> You should use `ForkTsCheckerWebpackPlugin` 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:
|
||
|
|
||
|
```js
|
||
|
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`.
|
||
|

### Overlay Integration
|
||
|
|
||
|
This plugin integrates with the most common Webpack HMR solutions to surface errors during development -
|
||
|
in the form of an error overlay.
|
||
|
|
||
|
By default, `webpack-dev-server` is used,
|
||
|
but you can set the [`overlay.sockIntegration`](docs/API.md#sockintegration) option to match what you're using.
|
||
|
|
||
|
The supported versions are as follows:
|
||
|
|
||
|
| Dependency | Version |
|
||
|
| ------------------------ | ----------------- |
|
||
|
| `webpack-dev-server` | `3.6.0`+ or `4.x` |
|
||
|
| `webpack-hot-middleware` | `2.x` |
|
||
|
| `webpack-plugin-serve` | `0.x` or `1.x` |
|
||
|
|
||
|
