How to make an HTTP request with Node.js?


In Node.js, you can make HTTP requests using various ways such as built-in http module, third-party modules like Axios, node-fetch library, and so on. However, here are the steps with built-in http module:

1. Import The ‘http’ or ‘https’ Module:

```
var http = require(‘http’);
```

1. Create The HTTP Request:

```
var options = { hostname: ‘www.google.com’, port: 80, path: ‘/’, method: ‘GET
};
```

1. Initialize The Request:

```
var req = http.request(options, function(response) { var str = ‘’;

//another chunk of data has been received, so append it to `str` response.on(‘data’, function (chunk) { str += chunk; }); //the whole response has been received response.on(‘end’, function () { console.log(str); }); }); ```

1. Handle Any Errors:

```
req.on(‘error’, function(e) { console.log(‘problem with request: ‘ + e.message);
});
```

1. End The Request:

This is required to actually send the request.

```
req.end();
```

All together:

```
var http = require(‘http’);

var options = { hostname: ‘www.google.com’, port: 80, path: ‘/’, method: ‘GET
};

var req = http.request(options, function(response) { var str = ‘’;

response.on(‘data’, function (chunk) { str += chunk; }); response.on(‘end’, function () { console.log(str); }); });

req.on(‘error’, function(e) { console.log(‘problem with request: ‘ + e.message);
});

req.end();
```

This will send a GET request to google.com and will log the response to the console. Replace the ‘hostname’, ‘path’ and ‘method’ in the ‘options’ object as necessary to fulfill your needs.
