Watch Error Request Handler Express Video Tutorials & Courses

Learn how to standardize error handling in Express.js using ds-express-errors. In this tutorial, I demonstrate how one global error handler can recognize errors from different libraries and convert them into a consistent response format for your application. 0:00 Intro 0:41 Installation and First setup 1:17 Error mapping 1:46 Strict error handling 2:18 Configuration: strict error handling 3:30 Configuration: mapping only installed libraries 4:04 Configuration: setting response format 5:19 Configuration: setting dev environments 6:36 Ending of part 1 7:09 Thank you for watching You will see how to add ds-express-errors to an existing Express.js project, reproduce real errors through Postman, enable stricter error recognition, and fully customize the final API response. The video covers: - Global Express.js error handling with `errorHandler` - Automatic error recognition - Duck typing and strict error detection - Selecting library mappers with `needMappers` - Passing original library objects through `errorClasses` - Strict Prisma and Zod error handling - Zero-dependency library architecture - Custom API response structures with `formatError` - Creating a JSON:API-style error response - Using the `err`, `req`, and `isDev` parameters - Configuring development environments with `devEnvironments` - Protecting sensitive error details in production - Development and production error responses ds-express-errors has zero dependencies. Instead of installing supported libraries internally, it allows you to pass the original objects from the libraries already used in your project. This makes it possible to use strict error checks while keeping full control over your project dependencies.
