An implementation of a http webhook-calling cron service running on Convex. This
was built as a demo app for userspace crons that are implemented in
cronlib.ts. We'll eventually port these directly into Convex but in the
meantime you can copy this file if you want to add userspace crons to your own
Convex project.
A userspace cron, as opposed to the built-in crons defined in crons.ts in a
Convex project, allow declaration of crons at runtime. The built-in crons in
Convex must be defined statically in the crons.ts file.
Note that it's possible that a cron will be lost is the system grinds to a halt so much that the rescheduler function hits a user timeout. We can add a cleanup job for this.
See http://cronvex.com for a live demonstration of this service.
