Gain access to TypeScript headers by typing the request (req) object

Is there a way to access headers in a method that is typed with Express.Request?

Here's an example code snippet:

    private _onTokenReceived(req: Express.Request, res: Express.Response): void {
        const header: string = req.headers.authorization;
    }

Unfortunately, in my example, I am unable to reach the headers.

Error: The "headers" property does not exist for the "Request" type.ts(2339)

Answer №1

Referencing a solution found on stackoverflow in regard to working with Express 4.x, the recommended approach is to utilize the req.get(headerName) method outlined within the Express 4.x API Reference.
