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.
