Deployment

Let's deploy the todo app to railway.app.

Prepare for Production

In order to deploy to a Node.js environment, you need to change Sveltekit's adaptor to @sveltejs/adapter-node.

1. Install adapter-node:

npm i @sveltejs/adapter-node --save-dev

2. In svelte.config.js, change the adapter:

svelte.config.js

import adapter from '@sveltejs/adapter-auto'
import adapter from '@sveltejs/adapter-node'
import { vitePreprocess } from '@sveltejs/kit/vite'

In order to deploy the todo app to railway you'll need a railway account. You'll also need Railway CLI installed, and you'll need to login to railway from the cli, using railway login.
