When building applications in Node.js, making HTTP requests is a fundamental task, whether you’re interacting with external APIs, fetching data, or communicating between services. While Node.js has a built-in http module for making requests, it’s not the most user-friendly or feature-rich solution. That’s where libraries like Got come in.
Got is a lightweight, feature-rich, and promise-based HTTP client for Node.js. It simplifies the process of making HTTP requests, providing a clean API, automatic retries, support for streams, and more. In this article, we’ll explore how to use Got for making HTTP requests and handling errors.
Before diving into the code, it’s important to understand why Got is a preferred choice for many developers:
To get started with Got, you’ll first need to install it in your Node.js project. If you haven’t already set up a Node.js project, follow these steps:
mkdir got-http-requests cd got-http-requests npm init -y
This command creates a new project directory and initializes it with a package.json file.
npm install got
Got is now added to your project, and you can start using it to make HTTP requests.
Got makes it easy to perform various types of HTTP requests. Let’s walk through some common use cases.
A GET request is the most common type of HTTP request, typically used to retrieve data from a server. With Got, making a GET request is straightforward:
const got = require('got'); (async () => { try { const response = await got('https://jsonplaceholder.typicode.com/posts/1'); console.log('GET Request:'); console.log(response.body); } catch (error) { console.error('Error in GET request:', error.message); } })();
A POST request is used to send data to a server, often to create a new resource. With Got, you can easily send JSON data in a POST request:
const got = require('got'); (async () => { try { const response = await got.post('https://jsonplaceholder.typicode.com/posts', { json: { title: 'foo', body: 'bar', userId: 1 }, responseType: 'json' }); console.log('POST Request:'); console.log(response.body); } catch (error) { console.error('Error in POST request:', error.message); } })();
Network issues or server errors can occur during HTTP requests. Got provides a simple way to handle these errors:
const got = require('got'); (async () => { try { const response = await got('https://nonexistent-url.com'); console.log(response.body); } catch (error) { console.error('Error handling example:', error.message); } })();
Got isn’t just about making simple GET and POST requests. It comes with several advanced features that can help you handle more complex scenarios.
Got allows you to customize requests by setting headers, query parameters, timeouts, and more:
const got = require('got'); (async () => { try { const response = await got('https://jsonplaceholder.typicode.com/posts/1', { headers: { 'User-Agent': 'My-Custom-Agent' }, searchParams: { userId: 1 }, timeout: 5000 }); console.log('Customized Request:'); console.log(response.body); } catch (error) { console.error('Error in customized request:', error.message); } })();
Got supports streaming, which is useful for handling large data or working with files:
const fs = require('fs'); const got = require('got'); (async () => { const downloadStream = got.stream('https://via.placeholder.com/150'); const fileWriterStream = fs.createWriteStream('downloaded_image.png'); downloadStream.pipe(fileWriterStream); fileWriterStream.on('finish', () => { console.log('Image downloaded successfully.'); }); })();

Got is a versatile and powerful library for making HTTP requests in Node.js. It simplifies the process of interacting with web services by providing a clean and intuitive API, while also offering advanced features like error handling, timeouts, and streams. Whether you’re building a simple script or a complex application, Got is an excellent choice for handling HTTP requests.
By using Got, you can write cleaner, more maintainable code and take advantage of its robust feature set to meet the needs of your application. So the next time you need to make an HTTP request in Node.js, consider using Got for a hassle-free experience.
