These clients can be packaged and published through NuGet for easy access to your API’s.

In this blogpost I will show you how to configure Swagger an NSwag so that up to date API clients are generated and compiled each time you build your solution.
#Nswag studio tutorial code#
With NSwag you can generate client code without having your API running, many generators require the swagger.json file that is exposed when you run your API but NSwag doesn’t. Once you have Swagger enabled you can also use the information Swagger exposes about your API to generate clients for the enpoints and operations your aspnet controllers expose. When you create an API using aspnetcore it is very easy to add a Swagger endpoint and SwaggerUI for exploring and testing your API. Want to generate a Typescript client, check out this post Background After achieving the desired output, we should save the current configuration as nswag.json file directly in SampleService.ApiClient project’s directory - NSwag should automatically convert all paths (assembly and references) to the relative form.Want to know how you can generate and compile up to date C# API clients each time you build your solution? Take a look at this example on GitHub. Generate Outputs button allows us to preview the generated client source code. Here’s the minimal configuration required to correctly generate C# client:

The easiest way to generate the manifest file is to use Windows UI application called NSwag Studio. Nswag.json defines a set of parameters required by NSwag for generating client code like input assembly and output file path, as well as other different options allowing to adjust the shape of output code to our needs. Steps to configure automated client generation □︎ Prepare nswag.json manifest □︎ Tested API is always called via client generated by SampleService.ApiClient project

Although there’s plenty of articles about generating C# client using NSwag, it took me a whole day to put all the necessary pieces together, so I decided to write my own description for future reference. Anyway, I decided to use NSwag because it was the easiest one to integrate with MsBuild and allows for generating clients directly from WebAPI server assembly. NSwag is built with dotnet but supports only C# and TypeScript clients generation. Swagger-codegen and openapi-generator are Java based CLI tools, so they require JVM to run but they allow to generate Rest API clients in a verity of programming languages. There’s a couple of existing projects on the market that allow generating C# client from OpenAPI ( Swagger) specification like: Taking into account those disadvantages, it’s worth considering publishing a client proxy alongside the service itself, especially if it’s possible to generate it automatically. Another problem is with propagating information about changes in the API and adjusting all clients to those changes. At the end of the day, we always need to write some set of classes that act as a client proxy, and if there is more than one consumer of a given service, we need to repeat that work in every one of them. Integrating two services using REST protocol doesn’t require any form of shared contract which makes the process extremely easy when both sides are developed in different technologies but it comes at a price. Today, more and more often this type of communication is used to connect backend services, too.

In the era of microservices and distributed systems, web browser applications written in JavaScript are not the only consumers of the REST API.
