About the project

Express middleware that makes handlers safe to retry: a duplicate request with the same Idempotency-Key gets the cached response replayed instead of re-running the handler. Storage is in-memory or Redis.

Useful for

Protect a payment endpoint from double charges when a POST request is retried
Configure RedisStore so idempotency works across multiple app instances
Implement a custom IdempotencyStore backed by Postgres or DynamoDB
