SqlEventLog

The durable half of the store: events are the truth, receipts dedupe by command id, the outbox carries deliveries, and the read model is rebuildable.

Source: packages/paykit/src/Store/SqlEventLog.ts Kind: Primitive

The durable half of the store: events are the truth, receipts dedupe by command id, the outbox carries deliveries, and the read model is rebuildable.

Every method is an Effect: a statement’s answer arrives asynchronously on every target worth supporting (D1 over HTTP, a pg client), and a store that pretends otherwise cannot reach one. append runs as one atomic unit, so the events, the state, the receipt and the deliveries land together or not at all.

Examples

import { SqlEventLog } from "@potion.run/paykit"

const log = SqlEventLog(sql, { now: () => 1_700_000_000_000, schema: "billing" })
const { version } = yield* log.append({ ... })
