@intouchg/fastify-webpack-hot

Allows using a NodeJS Fastify server for development with Webpack hot reloading when NODE_ENV=development

Register the plugin with Fastify and set the configPath option to the absolute filepath of your Webpack config file

Make sure the output.publicPath option has been set in your Webpack config

yarn add fastify
yarn add --dev @intouchg/fastify-webpack-hot nodemon

// package.json
{
	"scripts": {
		"dev": "NODE_ENV=development nodemon -w server.js"
	},
	"dependencies": {
		"fastify": "3.25.1"
	},
	"devDependencies": {
		"@intouchg/fastify-webpack-hot": "latest",
		"nodemon": "2.0.15"
	}
}

// server.js
const fastify = require('fastify')({ logger: true })
const path = require('path')

// Only require the plugin when NODE_ENV=development.
// This is not strictly necessary, the plugin does its
// own internal check for NODE_ENV=development.
if (process.env.NODE_ENV === 'development') {
	fastify.register(
		require('@intouchg/fastify-webpack-hot'),
		{ configPath: path.resolve(__dirname, 'webpack.config.js') }
	)
}

fastify.get('/', (request, reply) => reply.send({ hello: 'world' }))

fastify.listen(3000, (error, address) => {
	if (error) throw error
	console.log('Fastify server is listening on ' + address)
})
