> we can drop 4 lines into an JS/TS repo and have it publish

Could you talk a bit about this, or link out to any docs they've got for this? I'm curious about setting that up

I will give a high-level overview. Essentially, it is a workflow runner. You can set up "jobs" in a "pipeline" (dependency graph of jobs), and each job is just a bit of yaml. This yaml has individual keys controlling things like running a script, configuring the environment, controlling the docker image executing the job, etc..

These jobs / yaml blobs can be included into other files / projects using another one of these keys, "including" another job/pipeline via configuring the path to the repo & path to the file you want to import. You can override any properties really easily on these includes as well. Anyways, my .gitlab-ci.yml for building a container (any repo containing a top-level Dockerfile works zero-config, non-top-level can be configured) looks like this

    include:
      - project: 'public-tools/gitlab-extensions'
        ref: master
        file: '/.gitlab/ci/Docker-build.gitlab-ci.yml'

Then of course that file does the things to run a `docker build` script with secrets passed as build args etc

You don't even need to do that. Gitlab has repository configuration option to take CI config from another place. So you can have code only repo being built by a CI pipeline described elsewhere.
