# App load order
|
|
|
|
**Dev note**: As of March 2022, the skin is no longer part of the app load order at all. The document's graphs have
|
|
been kept untouched for posterity.
|
|
|
|
Old slow flow:
|
|
|
|
|
|
Current more parallel flow:

Key:
|
|
|
|
- Parallelogram: async/await task
|
|
- Box: sync task
|
|
- Diamond: conditional branch
|
|
- Egg: user interaction
|
|
- Blue arrow: async task is allowed to settle but allowed to fail
|
|
- Red arrow: async task success is asserted
|
|
|
|
Notes:
|
|
|
|
- A task begins when all its dependencies (arrows going into it) are fulfilled.
|
|
- The success of setting up rageshake is never asserted, element-web has a fallback path for running without IDB (and thus rageshake).
|
|
- Everything is awaited to be settled before the Modernizr check, to allow it to make use of things like i18n if they are successful.
