Elysia HMR HTML Plugin

This plugin adds fast-refreash using Server Sent Events to your html files.

You can view a example in example directory (is explained in this file).

Requisitos

• Browser with Server Sent Events Support
• Elysia package installed
• Bun. Not tested with NodeJS, but probably you will need some wrappers, Elysia/node package and HTMLRewriter package.

Installation

bun add --exact @gtrabanco/elysia-hmr-html

Usage

import { Elysia } from 'elysia';
import { staticPlugin } from '@elysiajs/static'
import { hmr } from '../src';

const app = new Elysia()
  .use(hmr({
    prefixToWatch: 'example/public' // Local path to watch for changes
  }))
  .use(staticPlugin({
    assets: 'example/public',
    prefix: '',
  })).listen(process.env.PORT || 0, ({ hostname, port }) => { console.log(`Elysia server started http://${hostname}:${port}`) });

Run the included example

git clone https://github.com/gtrabanco/elysia-hmr-html
cd elysia-hmr-html
bun install
PORT=3000 bun example

After that open https://localhost:3000/index.html in your browser and open ${EDITOR} example/public/index.html

Change something and save, you will see the changes in the browser :)
