Program the web using APIs in Javascript

Why?



  • API Design & paradigm are too different
  • Client side APIs and Server side APIs are hard to mashup
  • Authorization is a mess and need server side
  • Javascript rules the web

a platform and an API

On top of node.js


  • Platform: discover, try and mash up APIs.

  • Webshell API: integrate easily all your favorite APIs and script them into your apps.

API Endpoints become Javascript objects

CONSOLE - REPL

WEB API



GET or POST on
http://api.webshell.io/?code=SOME_JAVASCRIPT

API Explorer

Javascript SDK



Include this one line...
<script type="text/javascript" src="http://api.webshell.io/sdk/js?key={key}"></script>

... and start making API calls in a <script>

wsh.exec({
    code: function() { 
         apis.google.maps(); 
    },
    process: function(data, meta) { 
         $(body).append(meta.view) 
    }
});


SDK NODE




Std lib



  • Make HTTP request
  • Manipulate your Webshell app from the code
  • Render views
  • Geolocalize your user
  • Other various helper/debugging functions


Those are the building blocks.
All APIs on Webshell are made using them.

HTML View


JSON responses include both data and metadata

in these metadata, there is an important optional field: view

The metadata holds a view field that contains:
  • HTML markup
  • CSS
  • Javascript

Allows us to handle client-side APIs such as Google Maps, Youtube player, etc.

template your api data


var hn = get({
  url: 'https://news.ycombinator.com/rss',
  format: 'xml'
});
render(hn, { view: '<ul>\
<% for (var item in data.rss.channel[0].item) { %>\
<li>\
  <a href="<%= data.rss.channel[0].item[item].link[0] %>">\
    <%= (parseInt(item) + 1) %>. <%= data.rss.channel[0].item[item].title[0] %>\
  </a><br /><span>(<%= data.rss.channel[0].item[item].link[0] %>)</span>\
</li>\
<% } %>\
</ul>' });

exAmples of api with views


var m = apis.google.maps(); 
m.center('paris');

or

var player = apis.youtube.player('BbkE-qN-jOM'); 
player.playVideo();


Storage



Each user has a free workspace

  • Store their API scripts
  • 3rd party libraries
  • assets (img, css, js)

Edit files IN your workspace



Cloud9 Adapted to Webshell

FS Endpoints


All scripts that users make are public at the moment but we're working on private workspaces

To read a file:
http://api.webshell.io/raw/fs/username/path/to/file


or using STD Lib
cat(fs.thyb.helloWorld.sandbox.helloWorld);

Execute script


To access a file using STD Lib you can use fs builtin

fs.username.path.to.file

Execute the file by calling it:

fs.thyb.helloWorld();
or
or

APIs on Webshell


APIs are stored under the @bin account

http://api.webshell.io/raw/fs/bin/facebook/v0.1/facebook

we created the "apis" builtins, a handy shortcut

var apis = fs.bin

You can thus simply do apis.facebook.me();


One-liner authorization


All authorization protocols are implemented on Webshell. You can store your API Key on webshell and connect your user easily

apis.facebook.auth(); //connexion with OAuth2

apis.twitter.auth(); //connexion using OAuth1

Using REST APIs


once authorized, you can make calls without passing any token

apis.facebook.me();

or

apis.twitter.search('@webshell_');

OAuth.io



What's next?



Webshell will be based on OAuth.io for authorization

Webshell views will make use of web components (Shadow DOM, HTML Import, Custom elements ...) cf polymer project
