reqvsnode-fetch
The Go library "req" is a simple and easy-to-use library for making HTTP requests in Go. It is designed to make working with HTTP requests as simple as possible, by providing a clean and consistent API for handling various types of requests, including GET, POST, PUT, and DELETE.
One of the key features of req is its support for handling JSON data. The library automatically serializes and deserializes JSON data, making it easy to work with JSON data in your Go applications. Additionally, it supports multipart file uploads and automatic decompression of gzip and deflate encoded responses.
req also includes a number of convenience functions for working with common HTTP request types, such as sending GET and POST requests, handling redirects, and setting headers and query parameters. The library can also be easily extended with custom middleware and request handlers.
Overall, req is a powerful and flexible library that makes it easy to work with HTTP requests in Go. It is well-documented and actively maintained, making it a great choice for any Go project that needs to work with HTTP requests.
node-fetch is a lightweight library that provides a fetch()-like API for making HTTP requests in Node.js. It is a light-weight implementation of the Fetch API, which is mostly compatible with the browser's version.
node-fetch is primarily known as almost identical package fetch() is included in web browsers so it shares the same use common API. It's great starting point for people coming from front-end environment.
Highlights
Example Use
req.DevMode() // Use Client.DevMode to enable debugging details
// There are 2 ways to use req (like many other http clients)
// First way is to create a persistent session client:
client := req.C(). // defaults like timeout and headers can be set for the whole session
SetUserAgent("my-custom-client").
SetTimeout(5 * time.Second)
// defaults can be overriden and extended in each request
resp, err := client.R(). // Use R() to create a request and set with chainable request settings.
SetHeader("Accept", "application/vnd.github.v3+json").
SetPathParam("username", "imroc").
SetQueryParam("page", "1").
SetResult(&result). // Unmarshal response into struct automatically if status code >= 200 and <= 299.
SetError(&errMsg). // Unmarshal response into struct automatically if status code >= 400.
EnableDump(). // Enable dump at request level to help troubleshoot, log content only when an unexpected exception occurs.
Get("https://api.github.com/users/{username}/repos")
// Alternatively, it can be used as is without establishing a client
resp := client.Get("https://api.github.com/users/{username}/repos"). // Create a GET request with specified URL.
SetHeader("Accept", "application/vnd.github.v3+json").
SetPathParam("username", "imroc").
SetQueryParam("page", "1").
SetResult(&result).
SetError(&errMsg).
EnableDump().
Do() // Send request with Do.
const fetch = require('node-fetch');
// fetch supports both Promises and async/await
fetch('http://httpbin.org/get')
.then(res => res.text())
.then(body => console.log(body))
.catch(err => console.error(err));
const response = await fetch('http://httpbin.org/get');
// for concurrent scraping Promise.all can be used
const results = await Promise.all([
fetch('http://httpbin.org/html'),
fetch('http://httpbin.org/html'),
fetch('http://httpbin.org/html'),
])
// POST requests
await fetch('http://httpbin.org/post', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ name: 'John Doe' }),
})
// Proxy use:
const agent = new https.Agent({
rejectUnauthorized: false,
proxy: {
host: 'proxy.example.com',
port: 8080
}
});
await fetch('https://httpbin.org/ip', { agent })
// setting headers and cookies
const headers = new fetch.Headers();
headers.append('Cookie', 'myCookie=123');
headers.append('X-My-Header', 'myValue');
await fetch('https://httpbin.org/headers', { headers })
