Grunt is removing scripts and css in index.html - angularjs

Question

I have app deployed on heroku for some time. I always add components using bower install and then grunt to minimize, uglify and concatinate.
I have used yeoman to generate my Gruntfile.js
I installed a new library, included it in my index.html and run grunt command, it suddenly got removed from my index.html
On the left side, is what happens after I run Grunt, the right side is before I run grunt command
Here is a diff of the single javascript file removed
Here is the bower.json file

Does anyone know why Grunt is removing this files when I run Grunt?
PS: My code is on github, you can view it there

Answer 1

I will explain it with respect to bootstrap.
The wiredep picks files from bower_components/{bootstrap}/bower.json > "main" value. The bootstrap css file is not listed in that value.
For test/fun edit the above mentioned file as below:
"moduleType": "globals",
"main": [
"less/bootstrap.less",
"dist/js/bootstrap.js",
"dist/css/bootstrap.css"
],...
Notice the dist/css/bootstrap.css in "main" value.
Now run grunt or grunt build. You will find that bootstrap/dist/css/bootstrap.css is injected in app/index.html at the place you are expecting.
This is not the answer to your problem, you can refer to the bug on bootstrap
https://github.com/twbs/bootstrap/issues/16663.
However, my final suggestion would be downgrade to bootstrap 3.3.1 until they decide to resolve it.
Sorry, there is no better solution that I can think of, its "Their" decision.
You can check this for all the libraries that are having issue, either raise an issue at their Repo, or downgrade or wait until it becomes stable.

By looking at your problem, i have strong intuition that your new bower package must be using different version of common dependent,
For example: you new package might have been downloading latest version of common dependent package, i.e. JQuery and might be downloading it also at the time of installing itself.
and when while wiring dependencies you are facing this problem.
I am not sure but it works like this.
