I can't find the javascript in main bracket in bower - bower

Question

I already added the dependency of blueimp-file-upload in my bower file. ( bower.json)
{
"name": "redca-admin-web",
"version": "0.0.1",
"description": "RedCA Admin frontend implementation",
"authors": [
"redca <redca#samsung.com>"
],
"main": "index.html",
"license": "MIT",
"ignore": [
"**/.*",
"node_modules",
"bower_components",
"test",
"tests"
],
"dependencies": {
"jquery": ">=1.6",
"jquery-ui": ">=1.6",
"rdash-ui": "1.0.*",
"angular": "~1.2.21",
"angular-cookies": "~1.2.28",
"angular-bootstrap": "~0.11.0",
"angular-ui-router": "^0.2.10",
"bootstrap": "~3.2.0",
"font-awesome": "~4.1.0",
"angular-route": "~1.2.28",
"angular-resource": "~1.2.28",
"font-awesome": "~4.1.0",
"blueimp-file-upload" : "9.9.3"
},
"repository": {
"type": "git",
"url": "https://github.com/rdash/rdash-angular"
}
}
and I installed the dependency with the command, "bower install" and I can confirmed the dependencies in the folder, "src/components". But I can't find the
classes in main bracket in the followings. I saw the explanation of bower main page that the java script files in the main bracket are heavily used files.
main string or array: The primary acting files necessary to use your
package.
I am confused whether or not I misunderstood. Should I download the library that contains java-script files in main bracket separately?
