elucidata-react-coffee

Define React components using natural CoffeeScript syntax.

Example:

{div}= React.DOM

class UserChip extends React.Component
  @staticMethod: -> # becomes a static method on the React Component
    "hello"

  render: ->
    (div null, "Hello")

module.exports= UserChip.toComponent()

Alternate style:

{div}= React.DOM

module.exports= React.Component.toComponent class MyComponent

  render: ->
    (div null,
      "My Component!"
    )

Note

  • You'll need to use the result of .toComponent() in React.
  • When .toComponent() is called a new instance of the component is created. So you can use the constructor to fill any instance properties (specifically for ES6 classes). But don't do anything crazy in there. It's must ONLY be used for this purpose, as the constructor is discarded in the React component.

Installation

For browserify:

npm install elucidata-react-coffee --save

For bower:

bower install elucidata-react-coffee --save

Brunch

If you use brunch, you should look into the react-tags-brunch plugin, it plays wonderfully with react-coffee! The plugin interpolates (@div ...) kinds of calls into React.DOM.div(...).

Example:

class Login extends React.Component

  render: ->
    (@div className:'box',
      (@header null,
        "Login"
      )
      (@section className:'body',
        (@form role:'form',
          # ... etc
        )
      )
      (@footer null,
        (@button onClick:@whatever, "Login")
      )
    )

module.exports= Login.toComponent()

After it has been run through brunch, the output looks like this:

var Login,
  __hasProp = {}.hasOwnProperty,
  __extends = function(child, parent) { for (var key in parent) { if (__hasProp.call(parent, key)) child[key] = parent[key]; } function ctor() { this.constructor = child; } ctor.prototype = parent.prototype; child.prototype = new ctor(); child.__super__ = parent.prototype; return child; };

Login = (function(_super) {
  __extends(Login, _super);

  function Login() {
    return Login.__super__.constructor.apply(this, arguments);
  }

  Login.prototype.render = function() {
    return React.DOM.div({
      className: 'box'
    }, React.DOM.header(null, "Login"), React.DOM.section({
      className: 'body'
    }, React.DOM.form({
      role: 'form'
    })), React.DOM.footer(null, React.DOM.button({
      onClick: this.whatever
    }, "Login")));
  };

  return Login;

})(React.Component);

module.exports = Login.toComponent();

JSX and ES6

If you are using JSX and enable the --harmony flag, you can use react-coffee with ES6 classes as well:

class Test extends React.Component {

  static message() {
    return "Hello, mate."
  }

  getInitialState() {
    return {
      hello: 'Howdy'
    }
  }

  render() {
    return (
      <div>
        You said: { this.type.message() }<br/>
        I said: { this.state.hello }
      </div>
    )
  }

}

module.exports= Test.toComponent()
