What s new:

• Added express-validator error mapping

• Improved Mongoose and Prisma error checks

• Safer setConfig validation

• Logger bug fix and internal refactoring

Express apps often end up with scattered error handling. Try catch in routes, inconsistent responses, duplicated logic. Centralizing this logic can make apps more predictable and easier to maintain.

I published a open source error handling library called ds-express-errors that tries to address these issues in a structured, minimal way.
