This tool allows automating the migration from Cesium.defaultValue to javascript's nullish coalescing operator ?? (see Cesium Issue #11674 and PR #12507).
It worked as is on Cesium repository, but you may need to adapt it for your personal use case. Some known limitations are:
- comments inside
defaultValuecalls, - more than 2 intricate calls to
defaultValue, - works only for ES6
imports, not forrequire, - ...
Source code has no comment nor documentation (sorry about that 😕) but if you have any question don't hesitate to ask...
To work properly, you will need prettier installed, either globally, or in your project. This is to get rid of extraneous parenthesis introduced by the migration tool.
