wtf is fastify-schedule?

@fastify/schedule is a plugin for Fastify, a popular web framework for Node.js. It lets you set up recurring background tasks, things that need to run on a regular schedule, like checking a database every 20 seconds or sending a daily email. Without a tool like this, you'd have to manage timers and make sure those timers don't keep running after your server shuts down. Under the hood, it wraps a library called toad-scheduler. You create a "job" by defining what the task does, how to handle errors, and how often it should run. Then you hand that job to the scheduler. The main benefit is that when your Fastify server stops, all the scheduled jobs stop automatically, so you don't have to worry about leftover processes or manual cleanup. This is for developers already building apps with Fastify who need periodic background work. For example, if you have an API that needs to poll an external service for updates every few minutes, or a server that should clean up temporary files on a schedule, this plugin gives you a straightforward way to wire that in without standing up a separate task queue or cron system. The project is intentionally lightweight. It doesn't try to be a full job queue with persistence or distributed scheduling across multiple servers, it relies on toad-scheduler for simple interval-based jobs within a single Fastify process. For the details on what kinds of jobs you can create, the README points you to the toad-scheduler documentation, since the plugin is essentially a bridge between Fastify and that library.
