Possibility: Use global npm cache

[rfay]

I see this in the post-start:

    - exec: bash -ci 'worker=/mnt/ddev_config/diffy-worker-main; ( [ ! -d $worker/node_modules ] && npm install --prefix $worker && chown -R $DDEV_UID:$DDEV_GID $worker/node_modules ) || rm -rf $worker/node_modules'

You're doing an npm install without caching.. but you have ddev-global-cache mounted. And there's a whole npm_config_cache already built and waiting that could be used there (and cached). So you could add the environment variable

    - npm_config_cache=/mnt/ddev-global-cache/npm

And I don't think you'd have to chown or anything. (BTW, I think your chown is from an earlier version of this when you were running the container as root, so that should be removable now.)

@rfay addressed in #3. Indeed chown is not needed (just tested it). Please confirm I do not need anything else to use cache for npm.

I guess you're using it! Looks like it's doing fine!
