The only exception is that these callbacks might invoke next('route') to bypass the remaining route callbacks. You can provide multiple callback functions that behave like middleware to handle a request. app.all('/secret', (req, res, next) => instead of *. For example, the following handler is executed for requests to the route “/secret” whether using GET, POST, PUT, DELETE, or any other HTTP request method supported in the http module. There is a special routing method, app.all(), used to load middleware functions at a path for all HTTP request methods. GET method routeĮxpress supports methods that correspond to all HTTP request methods: get, post, and so on.
CB2 BOOK END CODE
The following code is an example of routes that are defined for the GET and the POST methods to the root of the app.
respond with "hello world" when a GET request is made to the homepageĪ route method is derived from one of the HTTP methods, and is attached to an instance of the express class. The following code is an example of a very basic route. With multiple callback functions, it is important to provide next as an argument to the callback function and then call next() within the body of the function to hand off control In fact, the routing methods can have more than one callback function as arguments.
In other words, the application “listens” for requests that match the specified route(s) and method(s), and when it detects a match, it calls the specified callback function. These routing methods specify a callback function (sometimes called “handler functions”) called when the application receives a request to the specified route (endpoint) and HTTP method. Specify middleware as the callback function (See Using middleware for details).
You can also use app.all() to handle all HTTP methods and app.use() to You define routing using methods of the Express app object that correspond to HTTP methods įor example, app.get() to handle GET requests and app.post to handle POST requests.
