System Documentation

What problem does it solve?

It prevents accidental breaking changes when you redesign database schemas, data models, API contracts, and error semantics that existing clients depend on.

Core Features & Use Cases

  • EMC-compliant change planning: Enforces Expand → Migrate → Contract sequencing for breaking changes and staged rollouts.
  • Compatibility-first migration design: Produces forward and rollback migration steps with compatibility classification, consumer readiness, and rollout/rollback ordering.
  • Machine-readable contract quality gates: Ensures RFC 7807-style validation errors, idempotency requirements, and rollback safety are explicitly included in the change plan.

Quick Start

Use data-api-contract-changer to generate a backward-compatible, idempotent, rollback-safe contract change plan for a database schema and API request/response update that must protect existing consumers.
