In this article, we are going to create a Web API with the help of node.js, Express, and MySQL. Web API is an application which serves HTTP based requests by different applications on different platforms, such as web, Windows, and mobile.
Routes. In order to implement our form handling code, we will need two routes that have the same URL pattern. The first (GET) route is used to display a new empty form for creating the object.The second route (POST) is used for validating data entered by the user, and then saving the information and redirecting to the detail page (if the data is valid) or redisplaying the form with errors (if.
Simple to use, blazing fast and thoroughly tested websocket client and server for Node.js.Express 5.0 alpha documentation is now available. The alpha API documentation is a work in progress. For information on what’s in the release, see the Express release history. Web Applications Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. APIs With a myriad of HTTP utility methods and middleware at.GET and POST is two common HTTP Requests used for building REST APIs. Both of these calls are meant for some special purpose. As per the documentation GET requests are meant to fetch data from specified resource and POST requests are meant to submit data to a specified resource. LIVE DEMO DOWNLOAD. Express framework provides router() method to create HTTP endpoints.
The first endpoint is for GET requests which returns all the posts, second is also GET request but returns a single post by ID, the ID is sent through params. Third is a POST request, which is adding a new post, next is the PUT request, for updating posts, and the last one is DELETE request. After we have added our first router module we need to update the.Read More
I just came across this while looking for a solution for getting route params in the middleware. So according to this, if I want to apply a middleware that needs the req.params object, I'll have to apply that middleware individually to each route? I thought that if I had set mergeParams: true, I'm supposed to get the whole route.params object in the middleware.Read More
The res object in Express.js, short for response, gives you a simple interface to respond to HTTP requests.In this article, we’ll cover the most important parts of res. Check-out this sister post if you’re interested in the req counterpart for access to information about the request. Basics of res res.send. send is perhaps the most well-known method that’s used on res.Read More

For example the express-params defines the following callback which allows you to restrict parameters to a given regular expression. This example is a bit more advanced, checking if the second argument is a regular expression, returning the callback which acts much like the “user” param example.Read More
I hope that by now the NodeJS server is up and running on your systems. So it’s best to jump directly to the point where one can send and receive form data from the client to the server. In this article, we will collect client’s data from one page using HTML forms and then display that data on other page using first the GET and then the POST methods in Node.js. Along the way, I will try to.Read More

We use the users array as our in-memory data-store. It gets initialized with an admin user. Next, we create our Express server and use the JSON middleware of the bodyParser package; it allows us to access the values of a JSON string stored in the body of a POST HTTP request. Then, we create three API-endpoints. Two GET endpoints so we can request a list of all users and one specific user by.Read More
