errata | Language-agnostic toolkit for error code enumeration

errata is a Go library. errata has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

errata is a general purpose, language-agnostic toolkit for error code enumeration (ECE). ECE is the process of defining all the ways in which your software can fail. Think of it as negative documentation (describing how your system fails as opposed to how it works). Consider a web application. Aren't HTTP status codes enough? No. They are sometimes useful (404 Not Found is fairly clear), but others are so vague as to be pretty meaningless (500 Internal Server Error). Often an additional semantic layer is required to communicate what exactly went wrong, and what the caller (be they a human, an API client, etc) can do in response. HTTP status codes are perfect for describing the category of problem (4xx client error, 5xx server error), but insufficient for the complex software of today. Major API vendors such as Twilio, Instagram, and Google Cloud recognise this and use ECE in some form. errata aims to provide a mechanism for any software to deliver world-class error handling.
