Packages you've used

Name a few libraries you've used and explain their role. Possible categories: HTTP, validation, database, logging, testing, queues.

Structure: “I used [package] for [problem]. We chose it because of [reason]. We ran into [limitation].”

Example categories to jog your memory: Express — routing, Zod — validation, Mongoose — document modelling, Pino — logging, test libraries — checking behaviour.

To be precise: you don't need to pretend to know the whole ecosystem. Being able to describe three real integrations, error configuration and dependency updates beats listing twenty names.
