On latest version of TS -

I am calling tsc like so:

 shell.stdin.write('tsc --jsx react --project tsconfig-fe.json ' + path + '\n');

I get an error saying:

error TS5042: Option 'project' cannot be mixed with source files on a command line.

this seems like an unncessary error. I would really like to be able to specify which tsconfig file to use ( I use one for backend and a different one for frontend ).

Is there any workaround for this besides taking all the settings from my tsconfig and putting them on the command line?
