问题
I was wondering if there are best practices for avoiding monolithic js files in AngularJS.
I would like to avoid having very large controllers.js/filters.js/services.js files. Instead, for the sake of manageability, I would like to have each controller/filter/service in its own file.
I would like to know, if there is a recommended convention for this approach as far as the directory structure and naming convention is concerned.
Also, what might be the best way to avoid adding a script tag in my app/index.html for each new file I create?

You may check this app: https://github.com/angular-app/angular-app
It is good example to start with.

It can be automated by grunt watcher for example. I use such a config for this task:
grunt.initConfig({
index: {
files: ['app/js/**/*.js'],
tasks: 'index:scripts'
}
})
grunt.registerMultiTask('index', 'Create index.html',
function() {
var files = grunt._watch_changed_files || grunt.file.expand(this.data);
var now = new Date().getTime();
var scripts_str = '';
var tpl = grunt.file.read('app/index.html.tmpl');
files.forEach(function(file) {
file = file.replace(/^app\//, '');
scripts_str += '<script src="' + file + '?bust=' + now + '"></script>' + "\n";
});
grunt.file.write('app/index.html', grunt.template.process(tpl, {
data: {
scripts: scripts_str
}
}))
console.log('File "index.html" created.');
});
index.html.tmpl:
<html>
<body>
...
<%=scripts%>
</body>
</html>

There are a few conventions out there and it doesn't really appear that any "best practice" has emerged yet.
That being said, the two conventions that I like put each controller/filter/service/etc in their own directory. As far as directory structure, for smaller projects I've seen a directory for each type of file. For large projects, I've seen a directory for each module with all controllers/filters/services for that module in that folder. This also forces you to split your app up into modules which is a nice side effect.
