xhr.js

xhr.js is a library(< 2Kb) to make AJAX/HTTP restful requests with XMLHttpRequest. It has similar API with Python-requests.

1. Install xhr.js ```sh npm install xhr.js ``` 2. import xhr.js UMD import is supported, then get global object: XHR. ```js import XHR from 'xhr.js'; // or var XHR = require("xhr.js"); ``` or link with script in html files: ```js ``` 3. use class XHR ```js var xhr = XHR(async); // default is async. you can set sync use XHR(false) xhr.on('success', function(result) {

console.log('status_code:', result.status_code);

console.log('status_text:', result.status_text);

console.log('response_type:', result.response_type);

console.log('text:', result.text);

console.log('headers:', result.headers());

console.log('json:', result.json()); // get the json result.

console.log('xml:', result.xml());

}); xhr.get('package.json', params={'a': 'b'}); ```
