Simplifying Angular Development with Swagger: A Step-by-Step Guide
Swagger offers more than just a user-friendly interface for exploring APIs. It also provides multiple generators that can produce code typically written by hand. As an Angular developer, this blog post will focus on the typescript-angular generator.

Generate Kotlin client for a complex web API
Failed to create a client for Java. The generator imports Java's types instead of TeamCity's. There are bugs described for the Java client in both the Swagger generator and the OpenAPI generator. Let's see how the generator behaves when building a Kotlin client.

Recommendations for Rust Open-API client generators? (Looking to experiment with api.congress.gov)
[swagger-codegen](https://github.com/swagger-api/swagger-codegen) generates code from an OpenAPI definition, and it supports Rust code output (client and/or server).

Document your API with OpenAPI standard
Swagger contains three greats tools to work with the specification: Swagger UI, Swagger Editor and Swagger Codegen. The Swagger UI renders OpenAPI specs as interactive API documentation, Swagger Editor is a browser-based editor where you can write OpenAPI specs and Swagger Codegen generates server stubs and client libraries from an OpenAPI spec like the OpenAPI generator.

Using Swagger API
We ran into some minor issues (#1201, #1210, #1355, #1356 and #1769) and fixed some stuff we stumbled upon along the way, although it didn't really bother us as well (#1451 and #1769).

Integrating Swagger/OpenAPI generated python server with existing Flask application
I am interested in integrating a swagger-codegen generated Python server with an existing Flask application. swagger-codegen generates a Python implementation based on the Connexion library from a Swagger API specification.

How to replace type methods in Swift to improve testability
The method takes a query, String, and a completion block, (Result<[String], Error>) -> Void, which is triggered once the request finishes. Its internal implementation doesn't really matter since it could be from an external framework or generated by a code generator from the API specification.

Kiota: OpenAPI-Based HTTP Client Code Generator
we are using the nswag tolchain (https://github.com/RicoSuter/NSwag) for generating c# and typescript clients based on openapi specs generated by swashbuckle. you can tweak some details using config file too.
it works quite well and even has integration in msbuild to avoid manual cli steps.

This week I released v2.1 of my text-templating library Weave that now uses Source Generators by default.
I'm mostly using it for C# API client generation from backend code - sort of similar to what a tool like NSwag Studio will do. I think NTypewriter has more flexibility though, and having a live view with the VS plugin makes development quick.

OpenAPI v4 Proposal
NSwag does a wonderful job of generating TypeScript clients from OpenAPI specs. Definitely give it a shot before killing your current setup.
