Problem: Property 'user' does not exist on type 'Request<ParamsDictionary, any, any, ParsedQs, Record<string, any>>'

When working with Express and jsonwebtoken, it's better to use res.locals to store user-related data rather than modifying the req object directly. This approach adheres to best practices and avoids potential issues with modifying the req object.

Here’s why:

Separation of Concerns: res.locals is designed for passing data to subsequent middleware or templates. It keeps the request object clean and unmodified.
Middleware-Safe: Using res.locals ensures that the data is available to other middleware without interfering with the original request object.

Instead of:

node -e "console.log(require('crypto').randomBytes(64).toString('hex'))" | wl-copy

CORS in Depth: The Last Word for Web Developers

By now, every web developer has heard of Cross-Origin Resource Sharing-or CORS for short-but few actually understand it. In this post, we attempt to explain CORS from the very ground zero up to the most common pitfalls and the best practices using the technology. Be it an experienced developer or a candidate aiming to ace your software engineering interview; this article will equip you with the knowledge needed to handle CORS.

What is CORS? The Same-Origin Policy Before explaining CORS, there is a need to have an understanding of the Same-Origin Policy. The Same-Origin Policy is a security policy implemented in all web browsers. It confines how resources from one origin interact with resources from another. An origin is defined as the combination of: Protocol, for example - https:// Domain, for example - example.com Port, for example - :3000
