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.

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.

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.
// 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"},
})
