@preact/preset-vite

An all in one preset for writing Preact apps with the vite bundler.

Features:

• Sets up Hot Module Replacement via prefresh
• Enables Preact Devtools bridge during development

Installation

First intall the preset package from npm:

npm install --save-dev @preact/preset-vite
# or
yarn add -D @preact/preset-vite

Enhance your vite config with the Preact preset plugin in your vite.config.ts or vite.config.js:

import { defineConfig } from "vite";
import preact from "@preact/preset-vite";

export default defineConfig({
  plugins: [preact()]
});

Options

Options can be passed to our preset plugin via the first argument:

export default defineConfig({
  plugins: [
    preact({ devtoolsInProd: true })
  ]
});

Available options

| Option | Type | Default | Description | |---|---|---|---| | devtoolsInProd | boolean | false | Inject devtools bridge in production bundle instead of only in development mode |

Babel configuration

The babel option lets you add plugins, presets, and other configuration to the Babel transformation performed on each JSX/TSX file.

preact({
  babel: {
    presets: [...],
    // Your plugins run before any built-in transform (eg: Fast Refresh)
    plugins: [...],
    // Use .babelrc files
    babelrc: true,
    // Use babel.config.js files
    configFile: true,
  }
})
