>Node JS library for using HackerEarth API

This library helps you to compile your code with [HackerEarth API v3](https://www.hackerearth.com/docs/api/developers/code/legacy/)

Using HackerEarth API you can compile and run your code using their [codeTable](https://code.hackerEarth.com)

<h2>PreRequisite</h2>
 - Make sure you are using latest version of nodeJS.
 - You have to obtain your client secret key from [HackerEarth Here](http://www.hackerearth.com/api/register/) and voila you are done!

<h2>Install</h2>

>npm install hackerearth-node

<h1>Set Up</h1>

``` js
var hackerEarth=require('hackerearth-node'); //require the Library
//Now set your application 
var hackerEarth=new hackerEarth(
                                '**********',  //Your Client Secret Key here this is mandatory
                                ''  //mode sync=1 or async(optional)=0 or null async is by default and preferred for nodeJS
);
var config={};
config.time_limit=1;  //your time limit in integer
config.memory_limit=323244;  //your memory limit in integer
config.source='';  //your source code for which you want to use hackerEarth api
config.input="";  //input against which you have to test your source code
config.language="C/C++/Py/C#"; //optional choose any one of them or none

```
<h1>Compile Your code</h1>
  - Using Callbacks

      ``` javascript
      //compile your code 
      hackerEarth.compile(config,function(err,response){
            if(err) {
              //deal with error
            } else {
              //deal with response
            }
      });

      ```

  - Using Promises

      ``` javascript
      //compile your code 
      hackerEarth.compile(config)
                              .then(result => {
                                //Handle Result
                              })
                              .catch(err => {
                                //Handle Error
                              });

      ```


<h1>Run Your Code</h1>
  - Using Callbacks

      ``` javascript
      //compile your code 
      hackerEarth.run(config,function(err,response){
            if(err) {
              //deal with error
            } else {
              //deal with response
            }
      });

      ```
  - Using Promises

      ``` javascript
      //compile your code 
      hackerEarth.run(config)
                          .then(result => {
                            //Handle Result
                          })
                          .catch(err => {
                            //Handle Error
                          });

      ```

<h3>Wanna Debug ?</h3>
>Append `debug=HE` before your node server command or whatever is calling HackerEath-node module.

<h1> Todos </h1>

- [x] Use ES6 in source and transpile to babel for older version and put it into distribution/
- [x] Promisify whole package
- [ ] Using travis build tools for testing
