Angular-React

Angular + React

Uso simples do React com Angular (ou outros frameworks)##

Dependências principais (relacionadas ao React)

  • Npm
{
  "coffee-react": "^4.0.0", \\ para uso do react como coffee (.cjsx)
  "gulp-cjsx": "^3.0.0", \\ wrapper para criar task
                          \\ do gulp usando o coffee-react
}
  • Bower
{
  "react": "~0.13.3", \\ dãh
}

React

# src/app/components/react/components.cjsx

ReactComponents = ReactComponents || {}
ReactFactories = ReactFactories || {}
ReactHelpers = ReactHelpers || {}

#ternary like comparison externalized
ReactHelpers.pluralize = (number)->
  return if number > 1 or number is 0 then 'ns' else 'm'


ReactComponents.ChildComponent = React.createClass {
    displayName: 'ChildComponent'
    getDefaultProps: ()->
      return {
        quantity: 0
      }

    # bound to onClick event and calls the fn passed on the attribute
    handleUpdate: ->
      @props.update?()

        <h2>Segundo Componente (Child)</h2>
        <p>
          Array contém {@props.quantity}

          # can only to use ternary comparison if externalized
          ite{ReactHelpers.pluralize(@props.quantity)}
        </p>
        <button onClick={@handleUpdate}>Change</button>

    </div>

  # called on React.render(Component(...))
  componentWillReceiveProps: (props)->

  }


# wrap classes with factory to use as
# Function with React.render(Component(), element)

ReactFactories.ParentComponent = React.createFactory(ReactComponents.ParentComponent)

Usando o component no angular

  # src/app/components/testDirect/controller.coffee

angular.module "HolmesAngularReact.controllers"
.controller "TestDirectiveCtrl", ($scope, $element) ->
  ##################################
  ## Init
  ##################################


  # function passed to React Component to be
  # called when something changed internally by the component
  $scope.changed = (state)->
    $.extend true, $scope, state
    $scope.$apply()

  # Render on directive load
  React.render ReactFactories.ParentComponent($scope), $element[0]

  $scope.$watch 'value', (v1, v2)->
    # Re-render after model has changed from interaction inside angular
    React.render ReactFactories.ParentComponent($scope), $element[0]
