Frontend Implementation
Authentication / Authorization
The frontend uses the Auth.js @auth/sveltekit library for for authentication and authorization.
- a single Keycloak provider is used
- the env vars
AUTH_CLIENT_ID
,AUTH_CLIENT_SECRET
,AUTH_ISSUER
andAUTH_SECRET
are used as config - the authorization code flow is used
- at sign-in the access token and refresh token are stored in a secure, HTTP only, encrypted JWT session cookie
- nobody can access the tokens in the session cookie, because it is encrypted and only the server-side of the frontend has the secret
- the session cookie is transferred for every request (the frontend is stateless)
- the access token will be refreshed via the refresh token if possible
- the session will expire at the same time as the last successful refreshed access token will expire
