Debugging & Resilience

Give users, processes, and components only the permissions and access they absolutely need. Reduces the risk of unintended behaviors and increases security.

Design systems and processes that catch errors early, ideally at compile or test time rather than at runtime. Implement strict type checks and use automated testing to catch potential issues before code even reaches production. If there's a situation you think should never happen, but the types suggest that it is in fact possible, rather than glazing over the type warnings, add code to handle that case and throw an error with a useful error message indicating that things are in an unusual state.

Write code that is easy to debug and troubleshoot. This can mean adding meaningful error messages, clear logging, or using tools that make debugging easier. You want to do the setup for these kinds of things now, before production is on fire.

No matter how well you write your code, eventually disaster will strike and you want to have processes and automations in place to make it as easy as possible for recovery. Automatic backups with simple restore automations you can run is an example of how to do this.
