JWT Auth Implementation

We implement a production-friendly JWT flow with short-lived access tokens, refresh cookies, protected API middleware, frontend retry behavior, and logout.

ExpressReactJWThttpOnly cookies

Fixed starting scope

Each feature starts with a clear base package, then grows only if your app needs more integrations, screens, or edge cases.

Integrated into your code

We adapt implementation to your stack instead of dropping a generic snippet that still needs hours of cleanup.

Handoff included

You get implementation notes, environment variables, testing notes, and what to watch before pushing to production.

What you get

Login endpoint with password verification.
Access and refresh token helpers.
Protected API middleware.
Refresh-token endpoint and logout endpoint.
Frontend API client pattern for token refresh.

How we implement it

Review existing user model and password hashing.

2

Add JWT secrets and token expiry configuration.

3

Implement login, refresh, logout, and current-user routes.

4

Protect selected backend routes with middleware.

5

Verify expired token, bad token, refresh, and logout flows.
