nodejs-rocks-in-docker's Issues

Patterns for npm watch?

Thank you so much for this write up of your talk. It has been immensely helpful!

Do you have any patterns or suggestions for using npm watch (or other techniques) for local development in Docker on typescript projects? Anything you can share here that meshes well with the your multi-stage approach would be greatly appreciated.

Thanks again!

Using invalid option

Hi!

You are using an invalid option with npm ci here:

nodejs-rocks-in-docker/dockerfiles/5.Dockerfile

Line 23 in 3ec7362

RUN npm install --only=development && npm cache clean --force

Which produces

npm WARN invalid config only="development" set in command line options
npm WARN invalid config Must be one of: null, prod, production

I think the goal here was to make sure that only the dev dependencies were added thus making sure that the non-dev dependencies were the same in your tests and in the final prod stage. But unfortunately, npm will ignore that option.

Cheers

Julien

docker-compose up errors out

Hi - Thanks for this repo. When cloning the repo locally and attempting to spin it up with this command$ docker-compose -f 2.docker-compose.yml up I get an error.

Should I be doing something before I attempt to docker-compose up the project? Thanks!

A small typo in these Dockerfiles on line 2 of each you've got NODE=ENV=production and it should be NODE_ENV=production.
