I am editting typescript now, and I'd like to be able to have it so, whenever :w is invoked, the shell runs tsc compiling my new save.

This beats having to !tsc every time.

Does something like this exist? A build or toolchain command is also an acceptable answer, as long as it can be done in one short command.

In Vim this is called an autocommand. The relevant help topic can be found by typing :h autocommand (sic!)

An example code to put into vimrc:

augroup typescript_save | au!
    autocmd BufWritePost *.ts execute '!tsc' expand("<afile>:p:S")
augroup end
