snowpackjs@snowpack/plugin-react-refresh
Transforms JavaScript files containing React components automatically to enable React Fast Refresh via Snowpack's HMR API.
npm install --save-dev @snowpack/plugin-react-refreshSetup
// snowpack.config.json
{
"plugins": ["@snowpack/plugin-react-refresh", {/* options: see below */}]
}Plugin Options
| Name | Type | Description |
|---|---|---|
babel |
boolean or object |
By default, this plugin uses Babel to add Fast-Refresh code to eligible JS files. If you want to configure & run this yourself, set "babel": false". Alternatively, you can pass a custom Babel configuration object to enhance or override the defaults. Most users won't need this. |
How it Works
This plugin will automatically inject HMR event handlers into any file containing a React component.
In most applications, you'll still want some top-level import.meta.hot handling code in your application for any non-React file updates. In our Create Snowpack App templates, this would be the HMR handling snippet found in src/index.js.
