将lodash注入Angular provider

Question

I've seen several questions about injecting lodash/underscore into controllers, but I need to put it into a custom provider. I can't seem to figure out how to do that. There is a similar question here that has an accepted answer, but I can't figure out how to re-purpose that technique for my situation.

I'm injecting lodash into angular as a separate module:

angular.module("lodash", [])
.factory("_", ($window) => {
    return $window._;
});

How would I modify or add to this in order to make lodash injectable into my provider?

Answer 1

To inject Lodash to both service providers and service instances use

angular.module("lodash", [])
.constant("_", window._);

instead . There are scenarios where using $window abstraction may be beneficial, but here it can be safely omitted.
