@form-engine-ts/storage-memory

In-process implementation of the form-engine-ts storage contract. It is useful for tests, demos, and ephemeral server workloads.

Install

pnpm add @form-engine-ts/core @form-engine-ts/storage-memory

Quick start

import { createMemoryStorageAdapter } from "@form-engine-ts/storage-memory";

const storage = createMemoryStorageAdapter();
await storage.saveSchema(schema);
await storage.saveSubmission(submission);

const responses = await storage.listSubmissions(schema.id, schema.version, {
  since: "2026-01-01T00:00:00.000Z",
  until: "2026-01-31T23:59:59.999Z"
});

Date boundaries are inclusive, and results are ordered by submission time and then ID. Data is cleared when the JavaScript process is restarted.

For bounded reads, call listSubmissionPage(formId, { version, pageSize, cursor, since, until, locale }). Pass the returned nextCursor to the next call while hasMore is true. The opaque cursor remains stable when submissions share a timestamp. Use metadataFilters for exact JSON metadata matching or filter for a custom predicate; both run before page sizing.
