livestub VS openapi-generator

Recently, inspired by Paul Daniels I added functionality to bootstrap sttp-livestub using openApi specification. More on it here: https://github.com/softwaremill/livestub/blob/master/README.md#openapi-integration

I'm also really happy with spec first. We're using openapi-generator[1] to generate types from a yaml schema (inverting the more standard approach of generating the yaml) in our Typescript (mostly Nest.js) backends, and export those types as packages for use in our frontends.

Manually writing API clients can be time-consuming and result in errors. This is where the OpenAPI specification and tools like OpenAPI Generator are helpful.

With your API defined, use the OpenAPI Generator to generate your code automatically. The PHP Flight generator — documented here — was provided by the author and, although its status is still marked as "experimental", it has been my production workhorse for over a year.

Until now, we relied on an open-source OpenAPI generator to build our SDKs. While it served us well, the maintenance and scalability challenges became apparent as we expanded our platform. Key pain points included:

OpenAPI Generator

Let’s learn how to generate an API client for an Angular project using the open-source OpenAPI Generator program. The OpenAPI Generator project offers a CLI for generating API client modules for multiple language targets by importing a YAML/JSON API specification file.

OpenAPI Generator is a versatile tool that emerged as a fork of Swagger Codegen, offering enhanced support and features. It allows developers to generate API client libraries, server stubs, and documentation for over 30 programming languages.
