Fun with Meteor, React, and React-Bootstrap

React-Bootstrap is pretty cool. I decided to play with it a bit.  Here are the basics.

In an already set up Meteor project (set up for React), it is added thus:

npm install --save react-bootstrap

Once this is done, you also need to add a bootstrap library. It could either be the twitter bootstrap meteor package, or you can link to it. For the purpose of my demo, I just grabbed a couple links from the React-Bootstrap site that they had handy for pulling in from a CMS:

index.html

<head>
    <!-- Latest compiled and minified CSS -->
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/latest/css/bootstrap.min.css" 
          rel="stylesheet">
    </link>

    <!-- Optional theme -->
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/latest/css/bootstrap-theme.min.css" 
          rel="stylesheet">
    </link>
</head>

Now, let's make a layout, and then create a component that we can render into it. We'll make it a modal, with a close button, and a "click me" button that will just add some text inside the modal. From this you can extrapolate how to make use of the framework.

Layout.jsx

import React from 'react';

export const Layout = ({content}) => (
  <div>
    <h1>My React App</h1>
    <hr />
    <div>{content}</div>
  </div>
);

And the component:

Mod.jsx

import React             from 'react';
import { Button, Modal } from 'react-bootstrap';

const handleClick = (event) => {
  event.preventDefault();
  document.querySelector('#foo').innerHTML="Yeah, I pushed it";
};

const handleHide = (event) => {
  event.preventDefault();
  document.querySelector('.static-modal').style.display='none';
}

export const Mod = () => (
  <div className="static-modal">
    <Modal.Dialog>
      <Modal.Header>
        <Modal.Title>Modal Title>
      </Modal.Header>

      <Modal.Body>
        One fine body...
        <p id="foo"></p>
      </Modal.Body>

      <Modal.Footer>
        <Button bsStyle="danger"  onClick={handleHide}>Close</Button>
        <Button bsStyle="primary" onClick={handleClick}>Click Me</Button>
      </Modal.Footer>

    </Modal.Dialog>
  </div>
);

And then just a route to show it:

router.js

import React       from 'react';
import { mount }   from 'react-mounter';
import { Layout }  from './Layout.jsx';
import { Mod.jsx } from './Mod.jsx';

FlowRouter.route("/", {
  action() {
    mount(Layout, {
      content: (<Mod />)
    });
  }
});

Let's talk about what we've got. I re-used/re-purposed some of the code my from last article, and, I modified the code the folks at React-Bootstrap demo on their site. The following will explain each of the code blocks above:

index.html is just to load in bootstrap css and theme from a Content Delivery Network.

Layout.jsx create's a container component that will hold our page content. It's just a div that accepts a component to render within itself.

Mod.jsx is our file of interest.
Note that React-Bootstrap exposes objects we can import and use. The two I'm using here are Button, and Modal. We need to import whatever objects we want to use. I only used two here, but look at their components documentation, there are a lot of goodies there to play with.

The next thing to know about React-Bootstrap components are that they have properties. The only property I used here was bsStyle, to get one each of a bootstrap danger, and success css class.

The click event handlers are just plain old Javascript. In the case of the Close Button, I simply grab the class of the Modal Component's parent, and hide it.  For the Click Me Button, I insert text into the paragraph element with id of "foo".  All very basic.  What is nice, is that using React, the mark-up and the code that it uses can be contained together.  Essentially, one file, one component.

Using Boost on OS X with Jetbrains' AppCode

So, after a serious pain in the butt getting Boost installed using the homebrew boost keg (see my previous post ), I decided to test things out using AppCode. Obviously, since this is a "3rd party library", a little massaging has to be done to get the libraries and headers found, and it's sufficiently obscure to deserve a post. I will list the procedure using my rig (OS X). You can extrapolate from this to your own kit. Right-click on your project icon, and select, "Project Settings..." , and scroll down to the "Search Paths" heading. About the third or so option down is "Header Search Paths" . Open that, and select either or both your type of build (Debug/Release), and then double click to the right of it under the "value" column. This will open up a window where you can add a path. Click the "+" and enter the path to the location of your copy of Boost's Headers. In my case: /usr/local/Cellar/boost/1....

Passing Functions and Lambdas into Functions with Ruby

Ruby's New Style of Lambda Functions f = ->( m ) { p m } f.call( 1 ) #=> 1 Which of course means the same thing as: f = lambda { |n| p n } f.call(1) #=> 1 Ruby Proc Objects p = Proc.new { |n| p n + 2 } p.call(2) #=> 4 Using a Function as a Closure in Ruby def domo( k ) ->(m) { p m + k } end z = domo( 5 ) z.call( 5 ) #=> 10 Function :domo takes a single parameter. Within :domo , we create a lambda that takes a single parameter, and adds that parameter to the value :domo takes in as its parameter. Then, we assign z to be the result of the lambda in :domo with its 'k' parameter loaded with 5. When z is called, we pass (another) 5 to it. This parameter loads the lambdas n parameter. The lambda executes, essentially adding n (5) + k (5) and yielding the result of 10. The thing about closures such as this is, we can load the initial value of the lambda to be whatever we want it to be when assigning the function :domo '...
