@robhicks/svelte-adapter-gun v0.0.3

@sveltejs/adapter-node

Adapter for SvelteKit apps that generates a standalone Node server.

Usage

Install with npm i -D @sveltejs/adapter-node@next, then add the adapter to your svelte.config.js:

// svelte.config.js
import adapter from '@sveltejs/adapter-node';

export default {
	kit: {
		adapter: adapter({
			// default options are shown
			out: 'build',
			precompress: false,
			env: {
				host: 'HOST',
				port: 'PORT'
			}
		})
	}
};

Options

out

The directory to build the server to. It defaults to build — i.e. node build would start the server locally after it has been created.

precompress

Enables precompressing using gzip and brotli for assets and prerendered pages. It defaults to false.

env

By default, the server will accept connections on 0.0.0.0 using port 3000. These can be customised with the PORT and HOST environment variables:

HOST=127.0.0.1 PORT=4000 node build

You can specify different environment variables if necessary using the env option:

env: {
	host: 'MY_HOST_VARIABLE',
	port: 'MY_PORT_VARIABLE'
}

MY_HOST_VARIABLE=127.0.0.1 MY_PORT_VARIABLE=4000 node build

Custom server

The adapter creates two files in your build directory — index.js and handler.js. Running index.js — e.g. node build, if you use the default build directory — will start a server on the configured port.

Alternatively, you can import the handler.js file, which exports a handler suitable for use with Express, Connect or Polka (or even just the built-in http.createServer) and set up your own server:

// my-server.js
import { handler } from './build/handler.js';
import express from 'express';

const app = express();

// add a route that lives separately from the SvelteKit app
app.get('/healthcheck', (req, res) => {
	res.end('ok');
});

// let SvelteKit handle everything else, including serving prerendered pages and static assets
app.use(handler);

app.listen(3000, () => {
	console.log('listening on port 3000');
});

Deploying

You will need the output directory (build by default), the project's package.json, and the production dependencies in node_modules to run the application. Production dependencies can be generated with npm ci --prod, you can also skip this step if your app doesn't have any dependencies. You can then start your app with

node build
