This is a simple example of authentication in Next.js, using NextAuth.js with Spotify.
Go to the Spotify for Developers Dashboard, creating an account if necessary, and create an app.
Create a .env.local file at the app root and add the Client ID and Client Secret as SPOTIFY_ID and SPOTIFY_SECRET.
Click on Edit Settings and add http://localhost:3000/api/auth/callback/spotify as a Redirect URI to allow local testing, then click save. You will need to add redirect URIs for each deployed application.
Generate a secred with openssl rand -base64 32 (for example) and add it to .env.local as SECRET.
Finally, run the development server:
npm run devOpen http://localhost:3000 with your browser to see the result.
You can start editing the page by modifying pages/index.tsx. The page auto-updates as you edit the file.
API routes can be accessed on http://localhost:3000/api/hello. This endpoint can be edited in pages/api/hello.ts.
The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.
