Over last few years, we've been hard at work on https://typespec.io/, a modern API definition language. This language is designed to meet the evolving needs of API developers, architects, and managers in an environment where the delivery of consistently high-quality APIs and related experiences is b...
Feels weird to introduce something that’s been around for a while. I’ve been using typespec for about a year. Works well but it needs to make some leaps to match with the OpenAPI spec.
As an FYI to myself: the leaps have not been made.
I would love to have TypeSpec enable support for examples, callbacks, and links. If it added those three, it’d be a total game changer (for me).
My position is one of always design an API first (produce the OpenAPI document of what you want to build) and get buy off from your customers/stakeholders. Then when we start coding, we know exactly what well the end result should be.
Even better would have the ability to do request/response validation via a OpenAPI spec in .NET. Still holding out on that pipe dream (I know it’s available via other languages).
