Recommended way to include bootstrap library in Em

Question

I am trying to install properly Twitter Bootstrap in my current ember-cli project. I did install bootstrap with bower :

bower install --save bootstrap

Now the library is downloded in /vendor/bootstrap/dist/(css|js|fonts) I tried what is mentioned here : http://ember-cli.com/#managing-dependencies replacing path and css files names but I get errors regarding the Brocfile.js file. I think the brocfile format has changed too much compared to the example.

I also tried to @import with the /app/styles/app.css file after moving the stylesheets in the /app/styles/ directory :

@import url('/assets/bootstrap.css');
@import url('/assets/bootstrap-theme.css');

But it did not work. The files are visible true dev server : http://localhost:4200/assets/bootstrap.css

Can someone throw me a bone here ?

Thx

Edit :

ember -v

Answer 1

$> bower install --save bootstrap

Afterwards add following two lines to your ember-cli-builds.js (or Brocfile.js if you are using an older version of Ember.js):

app.import(app.bowerDirectory + '/bootstrap/dist/js/bootstrap.js');
app.import(app.bowerDirectory + '/bootstrap/dist/css/bootstrap.css');

And voilà, ready to go!

updated 08/18/2015: adapted to new scheme introduced in Ember.js 1.13

Answer 2

On the terminal (For those using Node Package Manager)

npm install bootstrap --save

Using ember-cli, to import your installed bootstrap

Open the ember-cli-build.js file

module.exports = function(defaults) {
  let app = new EmberApp(defaults, {
    // Add options here
  });
app.import('node_modules/bootstrap/dist/css/bootstrap.min.css');
app.import('node_modules/bootstrap/dist/js/bootstrap.min.js');

That will do it if bootstrap is installed via the NPM installer.

Do not do this:

app.import('./node_modules/bootstrap/dist/css/bootstrap.min.css');
app.import('./node_modules/bootstrap/dist/js/bootstrap.min.js');

Update 3/30/15

plus ça change... I use ember-cli-bootstrap-sassy now, it seems to bring along minimum cruft while still letting me customize Bootstrap's variables.

Update 1/22/15

You should probably use Johnny's solution above instead of the lib I originally mentioned. I also like ember-cli-bootstrap-sass, because I can customize Bootstrap's variables directly in my project.

Original 7/11/14

If you're using a version of ember-cli that supports addons (0.35+, I believe), you can now use the ember-cli-bootstrap package. From the root of your app,

npm install --save-dev ember-cli-bootstrap

That's it!

Note: as @poweratom points out, ember-cli-bootstrap is somebody else's library which chooses to also include bootstrap-for-ember. Thus, this lib could get out of sync with official bootstrap version. However, I still find it a great way to get prototyping fast on a new project!
