5 Essential `req` Object Methods in Express.js

- The req object in Express is essential for handling HTTP requests and accessing data sent by the client. - req.param() retrieves parameters from the route, query string, or body (deprecated, use specific methods). - req.params accesses route parameters defined in the URL path. - req.query retrieves key-value pairs from the URL query string. - req.body accesses the body of the request, typically for POST/PUT/PATCH requests (requires middleware). - req.get(headerName) retrieves the value of a specific HTTP header sent by the client. - The deprecated req.param() method should be replaced with req.params, req.query, or req.body for specific access. - req.ip is a property that provides the client's IP address, useful for logging or security. - Understanding these req object methods enhances handling incoming requests in Express applications. - Developers are encouraged to share their favorite req methods or tips for working with Express.
