cos-request

1.1.0 verified Sat Apr 25 auth: no javascript deprecated

cos-request is a fork of the popular (now deprecated) request package, providing a simplified HTTP client for Node.js. Version 1.1.0 supports Node >= 8 and offers streaming, Promises, authentication, OAuth, proxying, and TLS/SSL. It aims to be the simplest way to make HTTP calls, with a callback-based API similar to the original request. The package is a drop-in replacement but is no longer actively developed; users are encouraged to migrate to modern alternatives like node-fetch or undici. Release cadence is sparse; last update is unknown.

Common errors

error Cannot find module 'request' ↓

cause Using require('request') but the package is named cos-request.

fix

npm install cos-request then require('cos-request').

error request is not a function ↓

cause ESM import default incorrectly (import request from 'cos-request' may not work).

fix

Use CommonJS require: const request = require('cos-request');

Warnings

deprecated cos-request is a fork of the deprecated 'request' package. It is not actively maintained. ↓

fix Migrate to modern HTTP clients like node-fetch (ESM), got, or undici.

gotcha Import using 'cos-request' not 'request'. Using 'request' will install the deprecated original package. ↓

fix Use 'const request = require('cos-request');'

gotcha Callback signature is (error, response, body) - response is an http.IncomingMessage, body is a string/Buffer. ↓

fix Ensure correct parameter order and types.

Install

npm install cos-request

yarn add cos-request

pnpm add cos-request

Imports

request
wrong
```
const request = require('request');
```
correct
```
const request = require('cos-request');
```
CommonJS require with the correct package name 'cos-request', not 'request'.

request.get

wrong

request.get('http://example.com', (err, res, body) => console.log(body))

correct

request.get('http://example.com', callback)

Convenience methods like get/post are directly on the request function.

request.defaults

wrong

request.defaults({baseUrl: 'http://api.com', function(err, res, body){}})

correct

const req = request.defaults({baseUrl: 'http://api.com'}); req.get('/endpoint', callback)

defaults returns a new request function with preset options; do not pass a callback directly.

Quickstart

Shows basic HTTP GET request with callback. Note the use of 'cos-request' package name.

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