crons

# Add scheduled jobs (crons) Define recurring jobs in convex/crons.ts targeting internal functions, with sane intervals and idempotent handlers. ## Steps 1. Create convex/crons.ts with cronJobs(). 2. Schedule internal functions (never public api.*) at the right interval. 3. Make handlers idempotent (safe to re-run); keep each run small. 4. Verify the job appears in the dashboard schedule. ## Rules - Schedule internal.* functions, never api.*. - Keep cron handlers small + idempotent. - Don't poll tight intervals for things a subscription can push.
