In Class Bootstrap

Bootstrap allows you to create great projects with beautiful CSS that looks good on a PC, a tablet or a phone.

To get started using bootstrap, create a new express project called Week02InClassBootstrap.

Step One: Install

There are two several ways to get Bootstrap. For now, I want you to use bower to install it. However, as an FYI, I will also provide a link that allows you to download bootstrap from their website. Download

Download with Bower

First copy our default bower.json and .bowerrc files from JsObjects.

cp $ELF_TEMPLATES/bower.json .
cp $ELF_TEMPLATES/.bowerrc .
bower install bootstrap --save

Remember that we define $ELF_TEMPLATES in our .bash_alias file. That file is maintained on JsObjects.

Download directly

Now we will add in bootstrap.

There are multiple ways to link in bootstrap. The two we care about are:

In this exercise, I want you to link in Bootstrap directly in the header. As an FYI, I will include information about use requirejs.

Link directly

We need to link in three files:

Here is what layout.jade looks like when you are done:

doctype html
html
  head
    title= title
    link(rel='stylesheet', href='/stylesheets/style.css')
    link(rel='stylesheet', href='/components/bootstrap/dist/css/bootstrap.css')
    script(src="components/jquery/dist/jquery.js")
    script(src="components/bootstrap/dist/js/bootstrap.js")
  body
    block content

With Require

Please skip this section. In Main.js we need to shim in bootstrap by adding it to the end of our list of shims in require.config:

paths: {
        "jquery": "javascripts/jquery-2.1.1",
        "bootstrap": "javascripts/bootstrap.min",
        // Lots omitted here
    },
    shim: {
        // Lots omitted here
        'bootstrap': {
            deps: ['jquery']
        }
    }
});

Since bootstrap depends on jquery, if we load bootstrap, then we are loading jquery. So we can change our require statement at the bottom of Main.js. Right now perhaps it looks something like this:

require(['jquery', 'MarkdownExtra', etc....

We should edit it so it looks like this:

require(['bootstrap', 'MarkdownExtra', etc....

Create

You need to create some files. You can just make a copy of index.jade and name it About.jade, then make a copy of index.js and name it About.js, then make a copy of layout.jade and name it BootstrapLayout.jade. You'll need to edit these files, as explained below, but making these copies gets you started.

So now that you have those files you need to tell Express that it should load the About page when it is requested. To do this, you need to add the following to app.js:

var about = require('./routes/About')
app.use('/About', about);   

Here is the contents of BootstrapLayout.jade:

doctype html
html
  head
    title= title
    link(rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css")
    link(rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap-theme.min.css")
    link(rel='stylesheet', href='/stylesheets/style.css')
    script(src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js")
    script(src="javascripts/require.js" data-main="javascripts/Main")

  body
  div.navbar.navbar-inverse.navbar-fixed-top(role='navigation')
    div.container
      div.navbar-header
        button.navbar-toggle(type='button', data-toggle='collapse', data-target='.navbar-collapse')
          span.sr-only Toggle navigation
          span.icon-bar
          span.icon-bar
          span.icon-bar
        a.navbar-brand(href='#') Prog282-Calvert

  block content

Or alternately, put this in it, which is probably a bit easier to use. It is only the last few lines that differ from above:

doctype html
html
  head
    title= title
    link(rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css")
    link(rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap-theme.min.css")
    link(rel='stylesheet', href='/stylesheets/style.css')
    script(src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js")
    script(src="javascripts/require.js" data-main="javascripts/Main")

  body
  div.navbar.navbar-inverse.navbar-fixed-top(role='navigation')
    div.container
      div.navbar-header
        button.navbar-toggle(type='button', data-toggle='collapse', data-target='.navbar-collapse')
          span.sr-only Toggle navigation
          span.icon-bar
          span.icon-bar
          span.icon-bar
        a.navbar-brand(href='#') Prog282-Calvert
      div.collapse.navbar-collapse
        ul.nav.navbar-nav
          li.active
            a(href='/') Home

  block content

When creating Jade from HTML you find on the bootstrap site, don't forget about: http://html2jade.org/.

And here is your About.js file:

var express = require('express');
var router = express.Router();
var fs = require('fs');

/* GET home page. */
router.get('/', function(req, res) {
  res.render('About', { title: 'About BridgePattern' });
});

module.exports = router;

Please note the changes to the line that begins res.render.

And here is About.jade:

extends BootStrapLayout

block content
  h1= title
  p Welcome to #{title}
