axios is a popular JavaScript library that allows you to make HTTP requests from a Node.js environment. It is a promise-based library that works in both the browser and Node.js. It is similar to the Fetch API, but with a more powerful feature set and better browser compatibility.
One of the main benefits of using axios is that it automatically transforms the response data into a JSON object, making it easy to work with.
Axios is known for user-friendly API and support for asynchronous async/await syntax making it very accessible in web scraping.
Got is a lightweight and powerful HTTP client for Node.js. It is built on top of the http and https modules and provides a simple, consistent API for making HTTP requests.
Got is one of the most feature-rich http clients in NodeJS ecosystem offering http2, proxy and asynchronous support making it ideal for web scraping.
Got also supports many specific domain integrations like AWS, plugins for various public APIs like github.
Note that Got has some inconsistent behaviors when it comes to web scraping use.
For example, it normalizes http headers
which is undesired functionality in scraping and should be disabled.
Highlights
Example Use
// axios can be used with promises:
axios.get('http://httpbin.org/json')
.then(response => {
console.log(response.data);
})
.catch(error => {
console.log(error);
});
// or async await syntax:
var resp = await axios.get('http://httpbin.org/json');
console.log(resp.data);
// to make requests concurrently Promise.all function can be used:
const results = await Promise.all([
axios.get('http://httpbin.org/html'),
axios.get('http://httpbin.org/html'),
axios.get('http://httpbin.org/html'),
])
// axios also supports other type of requests like POST and even automatically serialize them:
await axios.post('http://httpbin.org/post', {'query': 'hello world'});
// or formdata
const data = {name: 'John Doe', email: 'johndoe@example.com'};
await axios.post('https://jsonplaceholder.typicode.com/users',
querystring.stringify(data),
{
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}
);
// default values like headers can be configured globally
axios.defaults.headers.common['User-Agent'] = 'webscraping.fyi';
// or for session instance:
const instance = axios.create({
headers: {"User-Agent": "webscraping.fyi"},
})
const got = require('got');
// GET requests are default and can be made calling the module as is:
const response = await got('https://api.example.com');
console.log(response.body);
// POST requests can send
const response = await got.post('https://api.example.com', {
json: { name: 'John Doe' },
});
console.log(response.body);
// handling cookies
import {CookieJar} from 'tough-cookie';
const cookieJar = new CookieJar();
await cookieJar.setCookie('foo=bar', 'https://httpbin.org');
await got('https://httpbin.org/anything', {cookieJar});
// using proxy
import got from 'got';
import {HttpsProxyAgent} from 'hpagent';
await got('https://httpbin.org/ip', {
agent: {
https: new HttpsProxyAgent({
keepAlive: true,
keepAliveMsecs: 1000,
maxSockets: 256,
maxFreeSockets: 256,
scheduling: 'lifo',
proxy: 'https://localhost:8080'
})
}
});
