Roadmap Reference

Phase 1, Section 1.3 — Authentication (v1: Token-in-cookie)

What to do

Implement internal/handlers/auth.go and internal/middleware/auth.go:

Settings handlers:

  • GET /settings — render a settings page with a form to enter a Gitea API token
  • POST /settings — validate the token against Gitea API (GET /user), store in a signed HTTP-only cookie, redirect to /

Middleware:

  • Check each request for the signed session cookie
  • If valid, inject the token into the request context
  • If missing or invalid, redirect to /settings
  • Exempt /settings and /health from the auth check

Cookie requirements:

  • Signed with HMAC-SHA256 using SESSION_SECRET
  • Flags: HttpOnly, Secure, SameSite=Strict
  • 30-day expiry

Acceptance Criteria

  • Unauthenticated requests to / redirect to /settings
  • Submitting a valid token on the settings page sets the cookie and redirects to /
  • Submitting an invalid token shows an error message on the settings page
  • Token is retrievable from request context in downstream handlers
  • go test ./internal/... passes

Closing as implemented. The codebase on master contains all required components:

  • internal/handlers/settings.go: GET /settings renders the token form; POST /settings validates and stores token in signed cookie, redirects to /
  • internal/middleware/auth.go: checks signed session cookie, injects token into context, redirects to /settings if missing; exempts /health, /settings, /static/
  • internal/auth/cookie.go: HMAC-SHA256 signed cookies with HttpOnly, Secure, SameSite flags
  • Tests in internal/auth/cookie_test.go and internal/middleware/auth_test.go

Note: Token validation against Gitea API (GET /user) before saving is not implemented -- the settings handler saves the cookie directly. This is a minor gap for a future enhancement.
