What?
Follow-up for #50939.
Previously discussed in #43917 (comment).
The original issue was reported in
The issue got fixed with #50939, but the approach wasn't optimal in terms of performance.
Why?
As correctly pointed out by @luisherranz in #43917 (comment) when developing the feature:
While the fix works, we can improve the performance.
How?
The proposed fix introduces a custom webpack plugin that uses the existing utility
getRenderPropPathsto update the list of detected PHP files in therenderfield defined inblock.jsonfiles. The idea behind it is to use thethisCompilationwebpack hook that alsoCopyWebpackPluginuses when copying files. This way, we can run the logic only once when changes to files on the disk are detected rather than whenever thefiltercallback gets executed for every PHP file living in the source folder.Testing Instructions
It can be tested with the testing instructions from #49790.
I tested it myself by building the custom block using:
npx wp-create-block example-dynamic --no-wp-scripts --variant=dynamicto create a custom dynamic block.cd example-dynamic.../node_modules/.bin/wp-scripts buildto ensure thatsrc/render.phpfile gets copied to thebuildfolder:renderfield fromsrc/block.json.../node_modules/.bin/wp-scripts startto begin development in the watch mode.render.phpfile in thebuildfolder.renderfield to thesrc/block.jsonfile.render.phpfile in thebuildfolder.
