scheduled-job-schedule-valid-cron - ESLint plugin rules

This rule requires a scheduled job's config.schedule string to be a valid cron expression.

Severity#

error. This rule is enabled in the recommended preset.

What it Targets#

This rule targets files in your project's src/jobs directory. It reports a config.schedule whose string value isn't a valid cron expression. Interval-based schedules, such as { interval: 60000 }, aren't checked.

The following code is reported by the rule:

src/jobs/sync-products.ts
1export const config = {2  name: "sync-products",3  schedule: "not-a-cron",4}

Instead, use a valid cron expression:

src/jobs/sync-products.ts
1export const config = {2  name: "sync-products",3  schedule: "0 0 * * *",4}

Why it's Important#

Medusa uses the schedule value to determine when to run the job. An invalid cron expression means the job is never scheduled correctly.

Learn more in the Scheduled Jobs documentation.

Fixable#

This rule isn't auto-fixable.
