Midaz libs bring shared logic, patterns, and integrations into one place so you can focus on building what matters. Whether you’re working with Go, TypeScript, or both, these libraries help you stay consistent, reduce duplication, and move faster across the platform.
ImportantThis is the documentation for a deprecated version of Midaz. While it’s still operational and receives critical security updates, it’s no longer actively maintained or improved.For the best experience and ongoing support, switch to the newest version.
Each library is designed to work seamlessly with Midaz services, offering reusable components that simplify common tasks like error handling, logging, context management, validation, and more. Use them to:
  • Reuse proven business logic across projects.
  • Keep your services aligned with Lerian’s engineering standards.
  • Accelerate development while reducing room for mistakes.
