Example Use
const superagent = require('superagent');
// superagent supports both Promises and async/await
superagent.get('https://httpbin.org/get')
.then(res => console.log(res.text))
.catch(err => console.error(err));
const response = superagent.get('https://httpbin.org/get')
// post requests:
superagent.post('https://httpbin.org/post').send({ name: 'John Doe' })
// setting proxy
superagent.get('https://httpbin.org/ip').proxy('http://proxy.example.com:8080')
// settings headers and proxies
superagent.get('https://httpbin.org/headers').set('Cookie', 'myCookie=123').set('X-My-Header', 'myValue')
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 })
