Cookie dan sesi for Alpine.js
high5 checks
Session cookies are the keys to an account. Missing attributes turn a single XSS bug into full account takeover.
What Alpine.js must have
- Secure attribute on every cookie
- HttpOnly on session cookies
- SameSite=Lax or Strict on session cookies
- No session identifier in URLs or localStorage
- Session rotation after login and logout invalidation
How to fix it
- 1Set cookie attributes at the framework level so every cookie inherits them
- 2Move tokens out of localStorage to HttpOnly cookies
Alpine.js context
Lightweight reactive attributes for markup-driven interactivity.
x-html bypasses escaping. Keep CSP strict because Alpine evaluates expressions in the page.
