The req object represents the incoming request and contains properties such as the request method, URL, headers, and query parameters. Request and Response: Express provides a simplified API for handling HTTP requests and constructing HTTP responses.Middleware functions can be used for tasks like logging, authentication, error handling, parsing request bodies, and more. They are functions that have access to the request and response objects and can perform actions, modify the request/response, or pass control to the next middleware function in the chain. Middleware: Middleware functions are a core concept in Express.Routes are used to map specific URLs to specific handler functions, allowing you to handle incoming requests and generate appropriate responses. Routing: Express allows you to define routes to handle different HTTP methods (GET, POST, PUT, DELETE, etc.) and URL patterns.Here are some key features and concepts of the Express framework: It provides a simple and minimalistic approach to building web applications and APIs. Handling GET-POST-PUT-DELETE requests with Express TypescriptĮxpress is a popular web application framework for Node.js, which is built on top of Node.js’s HTTP module.Working with Express Router in Typescript.Add Express and Typescript into Node.js Project.Prune() that you can use to manually remove only the expired entries from the store. StartInterval() and stopInterval() methods to start/clear the automatic check for expired. Memorystore implements all the required, recommended and optional methods of the express-session store. serializer An object containing stringify and parse methods compatible with Javascript's JSON to override the serializer used.If you set this option, dispose() will only be called when a key falls out of the cache, not when it is overwritten. noDisposeOnSet By default, if you set a dispose() method, then it'll be called whenever a set() operation overwrites an existing key.Get a stale entry, as if it had already been deleted.
