![]() ![]() ![]() To extract that data from the request, we use the body-parse middleware functions. To exchange a large amount of data between the client and server, we use the POST method. ConclusionĪs you know, we can use URL query strings and parameters to transfer data from a client to the server. Now you know why and how we get data from the request body in the Express server. If the information is correct, it will redirect to another route using the Express res.redirect() method. I will get those data from the req.body and validate the data. In this example, I have a POST /login route where a user will send email and password to log in. Now I will be able to access any data from the request body using the req.body object. ![]() I am getting the package and using both urlencoded() and json() methods so that I can parse JSON and URL-encoded data in my server. If the client uses the fetch() API or Axios to send the request, they set the content-type header as application/json because they send data in JSON format.įor URL-encoded data: app.use(bodyParser.urlencoded(`) If you know that your server will only get data in a JSON format from the users, you will use this method. This json() method will parse any type of JSON data from the request body in the Express server. For that, you have to use two methods from this package to handle these two types of data.įor JSON data: app.use(bodyParser.json()) Most of the time, we parse JSON and URL-encoded data in our servers. The body-parser package parsers the JSON, raw buffer data, plain text, and URL-encoded data like x-www-form-urlencoded content type. How to Get Data From Request Body in Express Let's see how to apply it as a middleware function and get data in Express. You can use it after the installation by importing this package into your project. You can install this package using the following command: npm install body-parser Now, you need to install this package inside your project. If you don't have the server, you can follow our best setup guide for an Express server with TypeScript. To use the body-parser package, you need to have an Express server. Install body-parser Package to Get Data From req.body But you have to follow techniques to extract them. You can also use URL query strings and parameters in Express to get information from users to your server. In this lesson, you will learn how to extract those data from the request and access it through the req.body object inside a Node.js and Express server.
