superagent
Advanced tools
The superagent npm package is a small progressive client-side HTTP request library, and Node.js module with the same API, sporting many high-level HTTP client features. It is designed to make HTTP requests from both Node.js and browsers.
GET requests
This feature allows you to make GET requests to retrieve data from a server. You can include query parameters and handle the response asynchronously.
superagent.get('/search').query({ query: 'Manny' }).end(function(err, res){ /* handling response */ });POST requests
This feature is used to send POST requests to a server. You can send data as part of the request body and set custom headers.
superagent.post('/api/pets').send({ name: 'Manny', species: 'cat' }).set('X-API-Key', 'foobar').end(function(err, res){ /* handling response */ });Handling responses
This feature allows you to handle responses from the server, checking if the request was successful and then acting on the data received.
superagent.get('/some-url').end(function(err, res){ if (res.ok) { console.log('yay got ' + JSON.stringify(res.body)); } else { console.log('Oh no! error ' + res.text); } });Promises and async/await
Superagent can be used with promises and async/await syntax for better asynchronous control flow.
async function getData() { try { const res = await superagent.get('/some-url'); console.log(res.body); } catch (err) { console.error(err); } }Pipelining requests
This feature allows you to pipe the response stream directly to a file or another writable stream.
superagent.get('/some-url').pipe(fs.createWriteStream('result.txt'))Axios is a promise-based HTTP client for the browser and Node.js. It provides a simple API and handles requests and responses in JSON format. Compared to superagent, it has built-in CSRF protection and supports interceptors for request and response transformation.
The Fetch API provides a more modern alternative to XMLHttpRequest for making HTTP requests in the browser. It is not an npm package but a built-in browser API. It returns promises and works with async/await. Unlike superagent, it is not Node.js compatible without polyfills.
Got is a Node.js HTTP request library that is designed to be a simpler and more user-friendly alternative to Node's native 'http' module. It supports promises and async/await, streams, and advanced features like retries and timeouts. It is often compared to superagent for its simplicity and feature set.
node-fetch is a light-weight module that brings the browser Fetch API to Node.js. It is similar to superagent but is designed to mimic the Fetch API as closely as possible. It is promise-based and supports stream consumption.
Request is a simplified HTTP request client for Node.js, but it has been deprecated. It was known for its simplicity and wide adoption. Superagent offers a similar feature set but continues to be maintained and updated.

node:
$ npm install superagent
component:
$ component install visionmedia/superagent
Works with browserify and should work with webpack
request
.post('/api/pet')
.send({ name: 'Manny', species: 'cat' })
.set('X-API-Key', 'foobar')
.set('Accept', 'application/json')
.end(function(err, res){
});
Tested browsers:
Even though IE9 is supported, a polyfill window.btoa is needed to use basic auth.
Superagent is easily extended via plugins.
var nocache = require('no-cache');
var request = require('superagent');
var prefix = require('superagent-prefix')('/static');
prefix(request); // Prefixes *all* requests
request
.get('/some-url')
.use(nocache) // Prevents caching of *only* this request
.end(function(err, res){
// Do something
});
Existing plugins:
Please prefix your plugin with superagent-* so that it can easily be found by others.
