I work on code generator that creates TypeScript SDKs from OpenAPI specs and Zod (
https://zod.dev/) is a critical building block that I chose to power runtime validation in those SDKs. Depending on the complexity of a Zod schema, the resulting validation error message can contain a wall of JSON text - the serialised issues that were recorded during validation.
I wanted to try and create a small tool to help me better visualise and parse these errors. In code and the command line, we do also have the ability to pretty-print the errors but I still wanted a web UI which can let me share URLs for visualised errors.
I'm still iterating on it but would love any feedback if you do get to try it out.
Zod is such a great tool but its errors can be a bit hard to parse.
Reminds me a lot of https://github.com/yoavbls/pretty-ts-errors
