Dunno if this is the right place to this, but...
I have struggled with rollup-plugin-replace for half an hour about it being breaking stuff when I put react in my project when reading/watching https://code.lengstorf.com/learn-rollup-js/
The thing is that by default replace will transform node_modules modules too and in order to avoid it we have to add node_modules/** to the exclude option passed to replace.
You could put a tip in your article in order to help others not being trapped in this situation.
Ty 4 the awesome content.
I added a note in jlengstorf/code.lengstorf.com@688e3d7.
Thanks for the heads-up!
fix(replace): updated the replace config to exclude node modules
