#Vej.js (experimental)

Vej.js enables you to create a declarative layer on top of your HTTP library of choice.

Our goal is to allow you to define your resources whithout caring about the underlying HTTP library that's being used. So that you can later on replace it without having to change too much on your own code. You would only tell Vej what proxy to use given your new HTTP library.

##Usage

###Creating a resource Calling the resource function will give you a function with a few inner functions that maps to four default HTTP verbs GET, POST, PATCH & DELETE.

var jedis = vej.resource("jedis", vej.proxies.majaX);

jedis.all(); // GET /jedis
jedis.create({name: "Anakin Skywalker"}); // POST /jedis {name: "Anakin Skywalker"}
jedis("anakin-skywalker").detail(); // GET /jedis/anakin-skywalker
jedis("anakin-skywalker").update({
  name: "Darth Vader"
}); // PATCH /jedis/anakin-skywalker {name: "Darth Vader"}
jedis("anakin-skywalker").remove(); // DELETE /jedis/luke-skywalker

###Extending a resource Vej lets your extend a resource with extra actions:

var jedis = vej.resource("jedis", vej.proxies.majaX, function(){
  this.collection.get("with_experience"); // GET /jedis/with_experience
  this.collection.post("send_to_battle"); // POST /jedis/send_to_battle
  this.collection.patch("stand_your_ground"); // PATCH /jedis/stand_your_ground
  this.collection.remove("fallback"); // DELETE /jedis/fallback

  this.member.get("jedis_killed"); // GET /jedis/:id/jedis_killed
  this.member.post("add_disciple"); // POST /jedis/:id/add_disciple
  this.member.patch("change_lightsaber"); // PATCH /jedis/:id/change_lightsaber
  this.member.remove("remove_rank"); // DELETE /jedis/:id/remove_rank
});

jedis.with_experience({lightsaber: "double"}); // GET /jedis/with_experience {lightsaber: "double"}
jedis.send_to_battle({strategy: "peace & love"}); // POST /jedis/send_to_battle {strategy: "peace & love"}
jedis.stand_your_ground({formation: "cocoon"}); // PATCH /jedis/stang_your_ground {formation: "cocoon"}
jedis.fallback({with: "tail between your legs"}); // DELETE /jedis/fallback {with: "tail between your legs"}

jedis("anakin").jedis_killed({which: "jedi"}); // GET /jedis/anakin/jedis_killed {which: "jedi"}
jedis("anakin").add_disciple({name: "star killer"}); // POST /jedis/anakin/add_disciple {name: "star killer"}
jedis("anakin").change_lightsaber({color: "red"}); // PATCH /jedis/anakin/change_lightsaber {color: "red"}
jedis("anakin").remove_rank({which: "jedi"}); // DELETE /jedis/anakin/remove_rank {which: "jedi"}

###Limiting resource creation

Vej allows you to limit the amount of actions created for a given resource.

####Only

var jedis = vej.resource("jedis", vej.proxies.majaX, {only: ["all", "remove"]});

jedis.all() // GET /jedis
jedis.create // undefined
jedis("anakin").detail // undefined
jedis("anakin").update // undefined
jedis("anakin").remove() // DELETE /jedis/luke-skywalker

####Except

var jedis = vej.resource("jedis", vej.proxies.majaX, {except: ["all", "remove"]});

jedis.all // undefined
jedis.create({name: "Anakin"}) // POST /jedis {name: "Anakin"}
jedis("anakin").detail() // GET /jedis/anakin
jedis("anakin").update({name: "Vader"}) // PATCH /jedis/anakin {name: "Vader"}
jedis("anakin").remove // undefined

##Promises Vej wraps every request with a promise (Promises/A+). We rely on then/promise to provide this functionality.

users("luke-skywalker").detail().then(function(data){
  data // {name: "Luke Skywalker", age: 26, midichlorians: 3000}
}, function(error){});
