angularjs - Angular JS naming conventions ($, camelCase and PascalCase)

Question

What is the convention in AngularJS for prefixing providers with $? Should I prefix all custom services in my own code?

Looks like all things that come with angular have prefixed services, e.g. $http. Controllers, however, are not prefixed with $ in most articles. Also, all angular code comes with services named in camelCase, however I've also seen PascalCase in many blogs online. Which one is the convention?

Answer 1

1. Use PascalCase for controllers and for functions which return a constructor function that's supposed to be newed, e.g. var user = new User(). Controllers in Angular are viewed as scope constructor functions--thus the PascalCase.

2. Controllers should have Controller appended in their name. See http://demisx.github.io/angularjs/2014/09/14/angular-what-goes-where.html for naming examples.

3. Use camelCase for everything else.

These follow important Javascript conventions that dev around the world got used to.
