lib folder and is a lightweight
alternative to a traditional addon. It is not published to npm and is extremely
lightweight, only containing an
index.js and a
An in-repo addon can be used for several reasons.
Project Specific Addons
You may find that you have sections of your app that are good candidates for being addons, but they are not something you can make public, so rather than creating a traditional addon, you could make it an in-repo addon.
In repo addons are created in the
lib folder and are a good way to organize
your code by various features or sections of your app. An example of this would
be creating a
navigation addon and putting all of your navigation related
components and such inside that addon. This helps to keep related code all in
the same place.
Quick Addon Prototyping
If you have a quick idea for an addon, and want to iterate on it directly in your current Ember app, you can do this with an in-repo addon. Then, if you decide you want to make it a full fledged addon, you is easy to copy your work over.
Managing Vendor Code
You can take advantage of all available addon hooks. The
included hook allows
you to specify what vendor libraries should be pulled in and added.
