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.
Nestful is a Ruby library for making HTTP requests. It is designed to provide a simple, easy-to-use interface for making requests and handling responses. Nestful is often used for making requests to RESTful APIs.
One of the main features of Nestful is its ability to automatically parse JSON and XML responses and return them as Ruby objects.
This allows developers to easily access the data returned by an API without having to manually parse the response.
Netful is aimed at interacting with rest APIs and provides a convenient interface (see example below)
```javascript
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 })
```
```ruby
require 'nestful'
# GET request
response = Nestful.get('http://httpbin.org/get')
puts response.body
puts response.code
puts response.headers
# POST request
response = Nestful.post(
'http://httpbin.org/post',
:format => :json, :payload => { :title => 'foo', :body => 'bar', :userId => 1 }
)
puts response.body
# establish interface to a specific API
class Charge < Nestful::Resource
endpoint 'https://api.stripe.com/v1/charges'
options :auth_type => :bearer, :password => 'sk_bar'
def self.all
self.new(get)
end
def self.find(id)
self.new(get(id))
end
def refund
post(:refund)
end
end
Charge.all #=> []
Charge.find('ch_bar').amount
```
