Recurrence in the sandbox

Specifier: @nodetool-ai/sandbox-rrule. One module, rrule. Import it at the top of the body.

Build a rule and expand it

import { RRule } from "@nodetool-ai/sandbox-rrule";

const rule = new RRule({
  freq: RRule.WEEKLY,
  interval: 1,
  count: 4,
  dtstart: new Date(inputs.start)
});
return { dates: rule.all().map((d) => d.toISOString()) };

Parse an RRULE string

import { rrulestr } from "@nodetool-ai/sandbox-rrule";

const rule = rrulestr(inputs.rrule);
return { dates: rule.between(new Date(inputs.from), new Date(inputs.to)).map((d) => d.toISOString()) };

Gotchas

• UTC. Same guest limit as date-fns.
• Cap count / between. An unbounded all() can allocate without end.
