Highly Composable UI Components

Astarisx View's are stateless and completely decoupled from their Owner Component, making them highly composable. Without changing a line of code, Astarisx Views can be moved anywhere within your application. A View can even be completely removed without breaking your application. Teams can work independently of one another with the confidence that their work will easily integrate into the larger application.

Single Source of Truth

State is presented to Views as a single data model. It is the Single Source of Truth (SSoT). The SSoT is the Application's Data Context and is accessible from anywhere within the application. Communicating between components is no longer an issue, as every component has knowledge of the entire Application's state at any one time. You are guaranteed to have the latest copy of the Application's state when and where you need it.

Built in PushState Router

Astarisx comes with an optional pushState router out of the box and reduces the complexity in integrating client-side pushState routing into your application. Routing configuration and logic is moved out of the View and into the Business Logic Layer where it belongs. Astarisx uses Page, a micro client-side router inspired by the Express router, written by TJ Holowaychuk the creator of Express, amongst other things.

MediaQueryList Notifications

Astarisx is able to receive MediaQueryList Notifications within JavaScript. So as screen size or orientation changes, the application can be notified and respond to it from within your JavaScript code. This may be handy, for example, if you would like to make an ajax request based on a screen's orientation. You could even do some, or all, of your Responsive Design in JavaScript rather than in CSS.

Example Code

Create your Model

/* todo.js */
var Todo = Astarisx.createModelClass({
  description: {
    get: function(){
      return this.$state.description;
    }
  }
});

Create your ViewModel

/* todos.js */
var TodoModel = require("../models/todo");

// Model Constructor
var Todo = function(){
  return new TodoModel().apply(this, arguments);
};

var TodosViewModel = Astarisx.createViewModelClass({
  todosList: {
    kind: 'array',
    get: function(){
      return this.$state.todosList;
    }
  },

  addTodo: function(){
    var newTodo = new Todo({
      description: this.currentDescription
    });
    var next = this.$state.todosList.concat(newTodo);
    this.setState({
      todosList: next,
      currentDescription: ""
    });
  },

  currentDescription: {
    get: function(){
      return this.$state.currentDescription;
    },
    set: function(newVal){
      this.setState({
        currentDescription: newVal
      });
    }
  }
});

Create a ControllerViewModel

/* controllerViewModel.js */
var CVM = Astarisx.createCVMClass({
  //Specify a ViewModel's dataContext
  //This is referenced from the View
  todos: {
    viewModel: require('./todos'),
    get: function(){
      return this.$state.todos;
    }
  }
});

Build your View Components in React

class TodoList extends React.Component {
  constructor(props){
    super(props);
    this.state = {
      todos: Astarisx.state.appContext.todos
    };
  }
  componentDidMount(){
    Astarisx.register(this);
  }
  componentWillUnmount(){
    Astarisx.unregister(this);
  }
  render(){
    /*
      No props are passed in.
      All state is stored
      in this.state.appContext
    */
    // reference the todos data context
    let todos = this.state.todos;
    let list = todos.todosList.map(function(todo){
      return <li>{todo.description}</li>;
    });
    return <ul>{list}</ul>;
  }
};

var cvm = require('../viewModels/controllerViewModel');
class UI = React.createClass({
  componentWillMount(){
    //Initialize the application context
    Astarisx.init({
      controllerViewModel: cvm
    });
  }

  componentWillUnmount(){
    Astarisx.dispose();
  }

  addTodo(e){
    e.preventDefault();
    //Invoke action on dataContext
    this.state.todos.addTodo();
  }

  updateDescription(e){
    /*
      Assign value to currentDescription
      defined in the todos dataContext.
      This would usually be a field
      in a Model. We're doing this here
      to keep the demo simple.
    */
    let todos = this.state.todos;
    todos.currentDescription = e.target.value;
  }

  render(){
    //reference the todos dataContext
    let todos = this.state.todos;
    return (<form>
      <fieldset>
        <label htmlFor="task">TODO</label>
        <input ref="inputFld"
        id="task"
        type="text"
        placeholder="Enter Task"
        onChange={this.updateDescription}
        value={todos.currentDescription} />
        <button
        onClick={this.addTodo}>Add</button>
      </fieldset>
      {/*
        No props are passed
        to the TodoList component
      */}
      <TodoList />
    </form>);
  }
};
