What are the best practices for using JWT with TypeScript and Express?

When using JWT with TypeScript and Express, consider the following best practices: 1. Use strong secret keys. 2. Set appropriate expiration times for tokens. 3. Validate tokens on every request. 4. Use HTTPS to protect token transmission. 5. Store tokens securely on the client side.

How can I securely store JWTs on the client side?

You can store JWTs in HttpOnly cookies to prevent access via JavaScript, or use secure storage mechanisms like local storage with caution.

What libraries do you recommend for implementing JWT in a TypeScript Express app?

I recommend using libraries like jsonwebtoken for creating and verifying tokens, and express-jwt for middleware to protect routes.

Can you explain how to refresh JWTs?

To refresh JWTs, implement a refresh token mechanism where the client can request a new access token using a valid refresh token.
