DS Express Errors (centralizing errors library) — v1.8.0 & v1.8.1 Release Notes

Source: Dev.to

v1.8.0 – January 11, 2026

New features

• Custom error classes – Provide your own error classes (e.g., Zod, Joi) via setConfig for stricter verification.
• Selective mappers – Enable only the mappers you need through the configuration, reducing unnecessary checks.
• Rate‑limited logger – Added maxLoggerRequests (default 100 requests per minute) to prevent logger overload.
• Colourful logger output – Built‑in loggers now support colour for easier reading.
• New Prisma error codes – Added handling for P2005, P2006, P2007, P2011, P2027.
• Additional error type – Errors.GatewayTimeout(message) is now available.

Mapper improvements

• Express‑validator – Fixed incorrect logic.
• Mongoose – Corrected status code handling and added a check for BigInt in the internal safeStringify method.
• Sequelize – Fixed status code handling and updated mapping to include:
  • SequelizeOptimisticLockError
  • SequelizeEmptyResultError
  • SequelizeDatabaseError
  • SequelizeConnectionError
  • SequelizeTimeoutError
• Prisma – Expanded error handling and refined verification logic.

Logger refactor

• Added support for a custom logger.
• Fixed missing api import for logDebug.
