request

Simple HTTP GET requests

This code performs a simple HTTP GET request to Google's homepage and logs the error, response status code, and the response body.

const request = require('request');
request('http://www.google.com', function (error, response, body) {
  console.log('error:', error);
  console.log('statusCode:', response && response.statusCode);
  console.log('body:', body);
});

Streaming data

This code demonstrates how to stream data from an HTTP request directly to a file, which can be useful for downloading files or handling large amounts of data.

const request = require('request');
const fs = require('fs');
const stream = fs.createWriteStream('file.txt');
request('http://www.google.com').pipe(stream);

Custom HTTP headers

This code shows how to send a custom HTTP header (in this case, the User-Agent header) with a request. This is often required when using certain APIs, like GitHub's.

const request = require('request');
const options = {
  url: 'https://api.github.com/repos/request/request',
  headers: {
    'User-Agent': 'request'
  }
};
function callback(error, response, body) {
  if (!error && response.statusCode == 200) {
    const info = JSON.parse(body);
    console.log(info);
  }
}
request(options, callback);

Handling POST requests

This code snippet demonstrates how to send a POST request with form data, including how to upload a file as part of that form data.

const request = require('request');
const options = {
  method: 'POST',
  url: 'http://service.com/upload',
  headers: {
    'Content-Type': 'multipart/form-data'
  },
  formData: {
    key: 'value',
    file: fs.createReadStream('file.txt')
  }
};
request(options, function (error, response, body) {
  if (error) throw new Error(error);
  console.log(body);
});
