Is there a way to get OSX Finder to search through .ts (textscript) files? I really like using OSX's finder to quickly find a particular file and its content based on search, I need to work on in my web projects. We often have 100s upon 100s of separate files and I need to quickly find files quickly. 

OSX's Finder works on .html and .scss files wonderfully on my system. However, it doesn't seem to want to search inside of .ts files. Is there a way to enable this in OSX?
Unfortunately Quicklook and Spotlight need to know how to look into a ".ts" file. Sounds like they are (essentiually...) a text file but you need a way to tell macOS that.

Over on Stack Exchange there was an answer to a similar question that might be of help to you. It does involve a project on GitHub and may involve some programming skills on your part to make it work with ".ts" files, but it seems like a start, at least...
