Graviton

=========

Graviton is a headless browser based on [Electron](http://electron.atom.io/).

  

It's very similar to [Nightmare](https://github.com/segmentio/nightmare), but evaluated directly by electron, without process fork and ipc communication.

  

Because graviton work directly over electron, this allows you to use all features of electron.  

For example: listen all available callbacks, use events in callback, manipulate with WindowBrowser, WebContents, and other electron api.  

Adding new features has become much easier.

  

I tried replicate Nightmare API, for simple and fast usage by users which have experience with Nightmare.   

If anybody want to help identical copy Nightmare API, pull request welcome. 

 

## How to use

```

npm install electron-prebuilt

npm install graviton

./node_modules/.bin/electron test.js

```

## Example search in yahoo (like Nightmare yahoo example)

```javascript

    var Graviton = require('./lib/graviton');

    var vo = require("vo");

    

    vo(run)(function (err, result) {

        if (err) throw err;

    });

    

    function *run() {

        var graviton = yield Graviton.new({electron: {

            show: true,

        }});

    

        yield graviton.goto('http://yahoo.com', "dom");

        yield graviton.type('#uh-search-box', 'github nightmare');

        yield graviton.click('#uh-search-button');

        yield graviton.wait('#main');

        console.log(yield graviton.evaluate(function () {

            return document.querySelector('#main .searchCenterMiddle li a').href

        }));

    

        yield graviton.end();

    }

```

## Example 

```javascript

    var Graviton = require("graviton");

    var vo = require('vo');

   

    vo(run)(function (err, result) {

       if (err) throw err;

    });

    

    const GITHUB_LOGIN = '{SOME_LOGIN}';

    const GITHUB_PASS = '{SOME_PASS}';

    

    function *run() {

       var graviton = yield Graviton.new({

           electron: {

               show: true,

           }

       });

    

       try {

           yield graviton.goto("https://github.com/");

           yield graviton.evaluate(()=> {

               document.querySelector(`.header-actions .btn[href="/login"`).click();

           });

           yield graviton.wait();

           yield graviton.evaluate((GITHUB_LOGIN, GITHUB_PASS)=> {

               document.querySelector("#login_field").value = GITHUB_LOGIN;

               document.querySelector("#password").value = GITHUB_PASS;

               document.querySelector(".btn.btn-primary.btn-block").click();

           }, GITHUB_LOGIN, GITHUB_PASS);

    

           yield graviton.wait();

           console.log(yield graviton.evaluate(()=> {

               return document.title;

           }));

       } catch (e) {

           console.log(e);

       }

    

       yield graviton.end();

    }
