I don\'t want to use serve, I know it watches for changes, builds and serves.
I want to build upon changes.
According to \"ng help\", build takes parameter --watch
I don´t know if it´s a bug or just not documented, but it seems that you need to add a output path for watching with ng build -o dist -w while dist is your output path.
Update:
The command is now: ng build -op dist -w
Update 2:
The command is now: ng build --output-path dist --watch
