Build Pipeline Debugging

Note: This is only for debugging purposes and should not be relied upon.

To gain more visibility into what broccoli trees Ember CLI operates on, you can run the following command:

BROCCOLI_DEBUG="bundler:*" ember build

Fish equivalent is:

env BROCCOLI_DEBUG="bundler:*" ember build

For a brand new ember application (ember new your-app-name), DEBUG/ folder is going to be created with the following contents:

DEBUG/
└── bundler:application-and-dependencies
    ├── addon-tree-output
    ├── tree-shake-test
    └── vendor

addon-tree-output is the folder that contains all trees from Ember CLI add-ons; your-app-name is an application tree and vendor contains imported external assets.

Ember CLI uses broccoli-debug to generate debug output mentioned above.

More tips can be found in our PERF_GUIDE under DEBUG logging section.
