speeding up builds with tsc in child process

[ORESoftware]

I have this line of code in Node.js which sends stdin to a bash child process

shell.stdin.write('tsc --jsx react --module amd --target es5 ' + path + '\n');

even transpiling 1 file takes about 1.5 seconds. Is there anyway I could somehow speed this up? the only thing I can think of is to have tsc be already running as a server and send it an ipc or socket message.

The problem with using tsc --watch is that I need to add a hook, such that when tsc is done with a transpilation I can run some other code. I would be happy to use tsc --watch to speed this up but I don't know how in this case.

thanks, looking at that convo, it appears that --skipLibCheck is the best option for my needs, but I will keep researching
