Endpoints

Simple helper library for HTTP service clients. Endpoints works in the browser and in Node, using RequestAdapter to expose a common interface for Request Response objects, and superagent for Node and browser AJAX.

View the Endpoints API Reference.

tl;dr

var Endpoints = require('endpointsjs');

var myEndpoint = Endpoints.create('/some/url/pattern')
  .header('Content-Type', 'application/json')
  .methods(['get', 'post']);

myEndpoint.get()
  .send()          // Returns an Q Promise (Promises/A+)
  .invoke('text')  // You may invoke any method a RequestAdapter implements
  .done(console.log);

Install it

npm install endpointsjs

Usage

Use Endpoints to create an endpoint pattern, then call methods on that pattern and get promises back. No pyramid of doom. Code over configuration.

var Endpoints = require('endpointsjs');

var myEndpoint = Endpoints
  .create('/some/url/pattern')
  .header('Content-Type', 'application/json')
  .methods(['get', 'post']);

var promise = myEndpoint
  .get()
  .send(); // Returns an Q Promise (Promises/A+)

// You can do something like this
promise
.then(function(requestAdapter) {
  return requestAdapter.text();
})
.done(function(text) {
  console.log(text);
});

// Which is equivalent to
promise
.invoke('text')
.done(console.log);

Sending data to the server is also easy

var myOtherEndpoint = Endpoints.create('/some/other/url/pattern')
  .methods(['options', 'post', 'delete']);

myOtherEndpoint.post()
  .data({myData: 123})
  .send()
  ...
  .done();

It is also possible to build a URL by passing arguments

var myOtherEndpoint = Endpoints
  .create('/users/[userId]-[username]')
  .methods('get');

myOtherEndpoint
  .post()
  .param('userId', 123)
  .param('username', 'kahnjw')
  .send() // GETs the URL: /users/123-kahnjw
  ...
  .done();

Development

Bug fixes, new features, doc fixes are welcome and ecouraged. Open your pull early, make sure the code lints without error and the tests pass.

Setup

$ git clone [email protected]:kahnjw/endpoints.git
$ cd endpoints
$ npm install

Lint and test

$ gulp lint
$ gulp browserspec
$ gulp nodespec

Or just use the watch task

$ gulp watch

If new features are added or a bug is fixed, please cover them with new tests.

Footprint

Keep in mind this library is targeting both browser and Node environments. Footprint size should be as small as possible. To help with this there is a footprint task:

This prints out the minified size of the library, and the dependency tree to ensure that no libraries are double included.
