@reboost/plugin-prefresh v0.21.0

Prefresh Plugin

Enables support for hot reloading Preact components, so that you can develop your app faster.

Usage

Setup

Install it using npm

npm i -D @reboost/plugin-prefresh

Import it from the package

const { start } = require('reboost');
const PrefreshPlugin = require('@reboost/plugin-prefresh');

Add it to the plugins array

const { start } = require('reboost');
const PrefreshPlugin = require('@reboost/plugin-prefresh');

start({
  plugins: [
    PrefreshPlugin({
      // Options
    })
  ]
})

Options

excludeNodeModules

Type: boolean\ Default: true

Excludes all files which match /node_modules/. Disabling it will decrease performance.

Minimal setup needed

If you want this plugin to work, please part up your components and renderers to different files.

This won't work

index.jsx

import { h, render } from 'preact';

const App = () => {
  return (
    <div>Hi there!</div>
  )
}

render(<App />, document.querySelector('#app'));

This works

index.jsx

import { h, render } from 'preact';
import { App } from './App';

render(<App />, document.querySelector('#app'));

App.jsx

import { h } from 'preact';

export const App = () => {
  return (
    <div>Hi there!</div>
  )
}

Example

Improving performance by excluding unrelated files

By default, it runs the transformation on all files. You can run the transformation only on the files which need it by using UsePlugin.

const {
  start,
  builtInPlugins: {
    UsePlugin
  }
} = require('reboost');
const PrefreshPlugin = require('@reboost/plugin-prefresh');

start({
  // Other options
  plugins: [
    // Other plugins
    UsePlugin({
      include: /\.[jt]sx?$/, // Selects only the files with .js, .ts, .jsx or .tsx extension
      use: PrefreshPlugin()
    })
  ]
  // ...
})
