How to disable indexing for certain files in JetBrains IDE?

Question

IntelliJ IDEA

Hello,
I am using Intellij Idea. I write in TypeScript. For several hundred .ts files, there is one .js file each. Every time after compiling ts into js, ​​Idea re-indexes all files, and there is absolutely no reason for it to do this, because I'm only interested in ts and the environment hangs great. Is it possible to disable indexing for js files? I know that you can exclude directories in the module settings, but is it possible not to exclude a directory and only files that I don't need?

Answer 1

for Webstorm/PHPStorm, read Exclude files here , it says about files.

Answer 2

Right click on the folder -> Mask directory as -> Excluded
