Authenticating Sveltekit Applications

Based on the svelte application detailed on this blog to authentic a Svelte application with Auth0

Environment Variables

Create a .env file in your root directory and enter your credentials as shown below:

VITE_AUTH0_DOMAIN =xxx-xxxxxxxxx.xx.auth0.com
VITE_APP_CLIENT_ID =xxxxxxxxxxxxxxxxxxxxxxx

Add .env to your .gitignorefile

Developing

Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:

npm run dev

# or start the server and open the app in a new browser tab
npm run dev -- --open

Building

Svelte apps are built with adapters, which optimise your project for deployment to different environments.

By default, npm run build will generate a Node app that you can run with node build. To use a different adapter, add it to the devDependencies in package.json making sure to specify the version as next and update your svelte.config.cjs to specify your chosen adapter. The following official adapters are available:

• @sveltejs/adapter-node
• @sveltejs/adapter-static
• @sveltejs/adapter-netlify
• @sveltejs/adapter-vercel
• ...more soon

See the adapter documentation for more detail
