If you have some kind of "ng serve" feature like in Angular you can probably use volumes (bind mounts, to be specific) to bind your code on your host to the code inside your container. Then, every time you do a modification on your code, it will be updated automatically. You can use Watchtower to watch for updates to the image a container is instantiated from and automatically pull the update and restart the container using the updated image.
However, that doesn't solve the problem of rebuilding your own custom images when there's a change to the upstream image it's based on.
