Why does next.js work so slowly in faced 'Indexing'?

Question

I have worked in 'webstorm IDE', window 10, 8gb ram, i5 cpu.

But, When Webstorm have proceeded 'Indexing(please look down the picture)', My computer always worked so slowly

This is why???

Answer 1

You might need to ignore certain folders from indexing, such as the .next folder. This answer mentions that you can right click on a folder in Webstorm and click "Exclude from Index"
