Probably ~2-12 months of full time effort depending on how complete you want to be.  
If u want to utilize all existing libraries and features, we’d need a typescript-\>ruby decompiler and ruby-\>typescript compiler for the subset of ruby you care about. This is how py support works.

Examples:  
.py -\> .ts:
