    Great resource!

    Write database migrations in both directions so people can downgrade on failures.

    Good point. Personally, I take backups before upgrades and restore if anything goes wrong. But, I understand how downgrading sometimes is just easier.

    I have trouble coming up with a migration procedure that makes sense to me. I have the following in mind:

    1. Provide init scripts that produce a schema that matches beginning state of the current major.
    2. Provide major to major migration scripts.
    3. For every major, provide minor to minor migration scripts.
    4. Schema changes require at least a minor release.

    Make it possible to configure your system via ENV variables, ENV files and config files.

    I am bit worried about this one, environment variables can be a security concern. Specifically, I am not sure if I should allow providing secrets (like db connection strings) through environment variables. I am inclined to let people do what they want to, but issue a warning.

    Make it possible to disable authentication to add Authelia or LDAP through the webserver. Make clear that this is only to be used for external authentication.

    I am considering adding support for oauth through keycloak. My assumption is that if you are going to host your own LDAP, you can probably configure keycloak too. Do you think that makes sense?

    Make it possible to run multiple parallel instances of your software without affecting the database consistency, e.g. for high availability or horizontal scaling.

    Ideally, an instance shouldn’t be big enough to need it. I know, famous last words, but in my case I think it’s a bad problem to have. I am going out of scope, but I am wondering where is the line between discouraging large scale deployments and designing something pre-destined to obscurity.

    Telemetry

    Not even on my radar, thanks for bringing it into my attention 🙏





  • Most people get over it during uni when everyone is arguing over “X vs Y” language or “vim vs productivity”. At some point you realize how pointless these debates are and continue with your life.

    For anyone wanting to publish their code, remember it’s probably better than most OSS code. If you don’t believe that go read a python or js library:

    1. python’s celery for example has hard coded timeouts on every control operation
    2. react mui has so overcomplicated types that they break webstorm inspections
    3. I once found a typing hack on an python library where they reversed a string in order to conditionally import types only when mypy was running in order to avoid cyclic imports.

    I still love those libraries, use them at my work and will recommend them to anyone with similar needs as I.

    Last but not least, if you aren’t using git something is wrong with you 🤣.
