The fifth lifecycle event to trigger overall and the third to trigger inside the main Mosaic process.
It is called every time any source emits new pages and should return a boolean to indicate if other sources that share the same source namespace should re-run afterUpdate.
The shouldUpdateNamespaceSources lifecycle event is called with:
- updatedSourceFilesystem - Immutable filesystem for the source that changed i.e, not the source filesystem
- helpers - an object with useful methods
- options - the options specified for the plugin in the mosaic config file
The helpers provided with this lifecycle event are listed in the table below.
