    Local emulator for Google Cloud Storage

    What do you mean with running App Engine locally? There used to be a local development server, but that did not survive the 2to3 transition. GCP does ship a datastore and a pubsub emulator, but no Cloud Storage for example (someone wrote this one [1], which sort-of works but it does not behave 1:1 like GCS, so ironically my tests have to work around bugs in the emulator...).

    An EXIF-based photo assistant, organizer and workflow automation tool.

    I have an 8 year old app that reminds me a lot of this article.

    Something that's worked really well for me was that I created a plugin feature and most new features are actually plugins. This lets me add capabilities without touching or adding logic to the core code.

    Last night I added SQLite support as a plugin. 2 code files and one is unit tests.

    I don't know if this is the best approach but it's worked better than others in my 20+ years of writing software.
