# Problem ember-cli-password-strength, since 2.0.0, has support for asynchronous loading of the `zxcvbn.js` library. Since the library is 400k gzipped, it would make sense for us to make use of this. However, the addon does not provide a framework to actually include the library as part of the project. Instead, it assumes, if aync mode is on, that the library is locaded at `${config.rootUrl}/zxcvbn.js` We need to find a way to deal with this and switch to async mode. ## Subtasks - [ ] Turn on async mode for the addon as per instructions, by modifying the app's `ember-cli-build.js` and adding ```Javascript let app = new EmberAddon(defaults, { 'ember-cli-password-strength': { bundleZxcvbn: false } }); ``` - [ ] Provide the library, either at the expected path, or, more likely at our own path, by providing custom async loading facilities, similar to what we do with `ember-stripe-elements` https://github.com/code-corps/ember-stripe-elements/blob/master/addon/utils/load-script.js
