Codegen watch skip first run

Is your feature request related to a problem? Please describe. Currently, we run codegen, then codegen watch to ensure that the first run is successful before compiling the project. However, when the codegen watch is started, it runs an extra codegen before starting the watch.

Describe the solution you'd like

It would be nice if we could run the codegen watch and send a flag for it to not run its initial codegen until file changes.

Describe alternatives you've considered

No alternatives thought of
