@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,
  }
})
