cf-api-wrapper: A Wrapper for Codeforces API 
cf-api-wrapper is a wrapper for Codeforces API which provides an easy way to use it using Node.js.
Installation
npm install cf-api-wrapper
Usage
cf-api-wrapper provides functions to access all provided Codeforces API.
To use them, simply call the function along with the parameter(s) as an object after require-ing the wrapper.
Example:
var caw = require('cf-api-wrapper');
caw.user.info({handles: '14L'})
.then(function (result) {
// result is a list of User objects
// do something with it.
});
As you see each function returns a Promise, which later can be handled by using .then, .catch, .error, etc.
Every function has a timeout of 60 seconds, after which it will throw an Promise.TimeoutError error. The timeout is necessary as Codeforces API may not respond with the correct JSON/not responding at all because of several reasons such as the JSON object is too big, or any other reason.

A complete description of the API can be read at Codeforces API help page.
