app-to-addon-migrator

An opinionated cli tool to migrate Ember components from app to addons within a Yarn workspace.

NOTE: This cli tool works only with the following conventional folder structure for your Ember app.

|-app
|-packages
| |-addons
| |-engines
| | |-dashboards-engine
| | |-tickets-engine

Assumptions made by this tool

• Your Ember app lives in the root of your project folder.
• Engines live under packages/engines folder.
• Addons live under packages/addons folder.
• You are using Yarn workspaces.
• You are using POD structure for your components.

Install

npm i -g app-to-addon-migrator

Usage

1. ateam (wizard UI)

ateam

2. atam (classic CLI)

atam [entity] [entity-name] [dest-folder]
atam route default packages/engines/dashboards-engine

After running the above command, the route default from app/routes/default.js will be moved to packages/engines/dashboards-engine/addon/routes/default.js

Dry-run

If you just want to see/verify the movement use the --dry-run or -d option.

atam route default packages/engines/dashboards-engine -d

This will print something like (without actually copying the files):

Moving route.js
---------------
app/routes/helpdesk/default.js
packages/engines/dashboards-engine/addon/routes/default.js


Moving route template.hbs
-------------------------
app/templates/helpdeskdefault.hbs
packages/engines/dashboards-engine/addon/templates/default.hbs

...

Folder namespace

If your source entities are namespaced within a folder you can use the -f option to specify the same before copying. Say for example you want to move a component called widget from app/components/dashboards

atam component widget packages/engines/dashboards-engine -f dashboards
