What is got?
The 'got' npm package is a human-friendly and powerful HTTP request library for Node.js. It provides an easy-to-use API for making HTTP requests and supports many features like streams, pagination, JSON parsing, and more.
What are got's main functionalities?
Simplified HTTP requests
This feature allows you to perform HTTP GET requests with a promise-based API. The example shows how to fetch a webpage and log the HTML content.
const got = require('got');
got('https://sindresorhus.com').then(response => {
console.log(response.body);
}).catch(error => {
console.log(error.response.body);
});
JSON support
This feature automatically parses JSON responses. The example demonstrates fetching JSON data from an API and logging the parsed object.
const got = require('got');
got('https://api.example.com/data', { responseType: 'json' }).then(response => {
console.log(response.body);
}).catch(error => {
console.log(error.response.body);
});
POST requests
This feature allows you to send POST requests with JSON bodies. The example shows how to send a POST request with a JSON payload and receive a JSON response.
const got = require('got');
got.post('https://api.example.com/submit', {
json: {
key: 'value'
},
responseType: 'json'
}).then(response => {
console.log(response.body);
}).catch(error => {
console.log(error.response.body);
});
Error handling
This feature provides comprehensive error handling for various types of request failures. The example demonstrates how to handle different error scenarios when a request fails.
const got = require('got');
got('https://api.example.com/wrong-endpoint').then(response => {
console.log(response.body);
}).catch(error => {
if (error.response) {
console.log('The server responded with a non-2xx status code.');
} else if (error.request) {
console.log('The request was made but no response was received');
} else {
console.log('An error occurred when trying to perform the request.');
}
});
Stream support
This feature allows you to use got as a stream. The example shows how to stream a webpage's content and write it to a file.
const got = require('got');
const fs = require('fs');
const stream = got.stream('https://sindresorhus.com');
stream.pipe(fs.createWriteStream('index.html'));
Other packages similar to got
axios
Axios is a promise-based HTTP client for the browser and Node.js. It provides an API similar to got but also works in the browser. Axios has interceptors that allow you to transform requests and responses before they are handled by then or catch.
request
Request is a simplified HTTP request client that was very popular but is now deprecated. It had a callback-based API but also supported promises. Got is considered a modern alternative to Request with promise support by default.
node-fetch
Node-fetch is a light-weight module that brings the Fetch API to Node.js. It is a minimalistic and straightforward API that resembles the Fetch API provided by modern browsers, making it familiar to front-end developers.
superagent
Superagent is a small progressive client-side HTTP request library. It has a fluent API that allows chaining methods to configure requests, and it can be used on both server and client side. Compared to got, it has a more object-oriented style.
