Express can handle GET and POST requests without installing any third-party module. GET and POST are the 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 resources and POST requests are meant to submit data to a specified resource.


Please check the below code to know how to use GET/POST methods on Express

Fig 1: Preview of the output that you will get on running this code from your IDE.

const request = await fetch('/api');
try {
    const data = await request.json();
    console.log(data);
    return data;
}catch(error) {
    console.log('ERROR', error);
}

app.get('/api', (req,res) => {
    res.send({key: apiKey})
})

Instructions

Follow the steps carefully to get the output easily.

  1. Install Visual Studio Code IDE on your computer.
  2. Install node JS to run express code
  3. Create a JavaScript file and paste the code under express import statement (refer the output image )
  4. Save and run the code using node filename to generate the output
  5. With '/api' as end point type '/api' on the localhost URL to generate the key

I found this code snippet by searching for ' http get and post request in express js ' you can try any such use case!

Environment tested


I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in Visual Studio Code 1.73.1.


Using this solution, we are able to implement GET/ POST methods on Express with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to implement GET/ POST methods on Express
