Technique

FastifyRefresh automatically injects a WebSocket client to enable live browser refresh—no setup required.

Usage

import fastifyWebsocket from '@fastify/websocket';
import { FastifyRefresh } from 'fastify-refresh';

// Register WebSockets
app.register(fastifyWebsocket);

// Create FastifyRefresh instance
const fastifyRefresh = new FastifyRefresh(app);

// Trigger refresh manually when needed
fastifyRefresh.refresh();

You decide when you trigger the refresh. I usually just trigger it with something like chokidar:

Suggested Usage

if (isDev) {
    app.register(fastifyWebsocket);
    const fastifyRefresh = new FastifyRefresh(app);

    chokidar
        .watch(publicDir, { ignoreInitial: true })
        .on('all', (event, filePath) => {
            fastifyRefresh.refresh();
        });
}

Installation

npm  install  fastify-refresh
