@rules-cascade/common

The contract the other Rule Cascade packages share. It has no dependencies and evaluates nothing.

| Export | What it is | |---|---| | The types | RuleSetDocument, Rule, Bundle, Manifest, EvaluationRequest, EvaluationResult, Finding, Operators and the rest of the specification's shapes | | @rules-cascade/common/cron | The five-field cron schedule the manifest client and the rule server run on: parseCron, startCronTimer, checkTimeZone, CronSchedule, CronError. Also exported from the main entry | | VERSION | The version every package of this release carries |

import type { Manifest, EvaluationRequest } from '@rules-cascade/common';
import { parseCron } from '@rules-cascade/common/cron';

parseCron('*/15 * * * *').next(new Date('2026-10-05T10:07:00Z'));   // 2026-10-05T10:15:00.000Z

You rarely install it on its own: @rules-cascade/core re-exports everything in it, and @rules-cascade/client and @rules-cascade/server depend on it.
