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…

Hey all! At Zuplo, we couldn’t find an open-source documentation solution that met our high standards for both trustworthiness and programmability, so we decided to create our own (you know, as you do). Zudoku is a framework for building high quality, interactive API documentation. We’ve now released it as an OSS project under a MIT license: https://github.com/zuplo/zudoku) It’s predominantly built around a highly interactive API reference powered by OpenAPI (with GraphQL support on the way), but also has MDX support, authentication options such as Auth0 and Clerk,…
