What is the "main file" property when doing bower init?
BowerBower Problem Overview
What is the use of property main file when you run bower init? I have been looking and many people says that it currently has no purpose.
Is that true? Bower's documentation doesn't explain it either.

Solution 1 - Bower
According to the Bower.io documentation

I think it's more for the package management, and build tools like Grunt and Brunch. For example, Bootstrap's bower.json
looks like :
{
"name": "bootstrap",
"version": "3.0.3",
"main": [
"./dist/css/bootstrap.css",
"./dist/js/bootstrap.js",
"./dist/fonts/glyphicons-halflings-regular.eot",
"./dist/fonts/glyphicons-halflings-regular.svg",
"./dist/fonts/glyphicons-halflings-regular.ttf",
"./dist/fonts/glyphicons-halflings-regular.woff"
],
"ignore": [
"**/.*",
"_config.yml",
"CNAME",
"composer.json",
"CONTRIBUTING.md",
"docs",
"js/tests"
],
"dependencies": {
"jquery": ">= 1.9.0"
}
}
When I build in Brunch, it pulls these files from my bower_components
folder in my public
folder.
Solution 2 - Bower
According to Bower's JSON Specification (https://github.com/bower/spec/blob/master/json.md#main), the "main" property is used to list the files primarily used in the project. The files listed are not actually used by Bower in any way, they are apparently there for the purpose of being used by other build tools.
Here is the official specification:
> ### main
>
> Recommended
> Type: String
or Array
of String
>
> The primary acting files necessary to use your package. While Bower does not directly use these files, they are listed with the commands bower list --json
and bower list --paths
, so they can be used by build tools.

> * Preprocessor files like CoffeeScript should be compiled.
> * Do not include minified files.
> * Filenames should not be versioned (Bad: package.1.1.0.js; Good: package.js).
