Fundamentally every application consist of two parts: the frontend and state machine.If yours has three, you have one too many.

noBackend

Welcome, to the wonderful world of noBackend,
where frontend developers build full stack apps,
without thinking about the backend.

Frontend-Driven API

  • Provide API rather than protocol
  • Tennant oriented
  • simple JSON-Oriented Data Format
  • Async with Promises

For Profile Management

// sign up
account.signUp('joe@example.com', 'secret');

// sign in
account.signIn('joe@example.com', 'secret');

// sign out
account.signOut();

// reset password
account.resetPassword('joe@example.com');
[...]

Data Storage

// add a new object
var type = 'note';
var attributes = {color: 'red'};
store.add(type, attributes)
  .done(function (newObject) {});
  .fail(function (error) {});

// update an existing object
var type = 'note';
var id = 'abc4567';
var update = {size: 2};
store.update(type, id, update)
  .done(function (updatedObject) {});

Data Retrieval

// find one object
var type = 'note';
var id = 'abc4567';
store.find(type, id)
  .done(function (object) {});

// Load all objects
store.findAll()
  .done(function (objects) {});

// Load all objects from one type
var type = 'note';
store.findAll(type)
  .done(function (objects) {});

// remove an existing object
var type = 'note';
var id = 'abc4567';
store.remove(type, id)
  .done(function (removedObject) {});
