@idempot/core

Core idempotency logic for framework adapters and storage backends.

Usage

Install alongside a framework adapter:

npm install @idempot/hono-middleware @idempot/sqlite-store

import { idempotency } from "@idempot/hono-middleware";

For Package Maintainers

Framework adapters and storage backends depend on this package for:

• Request fingerprinting (generateFingerprint)
• Validation logic (validateIdempotencyKey, checkLookupConflicts)
• Resilience patterns (withResilience)
• Default configuration (defaultOptions)
• Store interface definition (IdempotencyStore)

TypeScript Support

This library uses JavaScript with JSDoc comments for type information. Each package ships .d.ts declaration files generated from the JSDoc-annotated source. TypeScript picks them up automatically via the types field in each package.json.

import { idempotency } from "@idempot/core";

The declarations are generated at publish time to ensure types match the published version.
