Part 0: Setup

We will need some basic setup to get things going. It is not the topic of this tutorial to explain how to use ASP.NET Core. For that please refer to other sources.

Your find the project RoboPlant

Remarks

So all the initial setup can be seen in Startup.cs:

• Ensure to use only lowercase URLs which is a best practice.
• Tweak the formatters:
  • remove all default formatters because we want only to return JSON for now
  • add a tweaked JSON formatter which will not serialize NULL and default values to reduce the size of the JSON. This is better to read for us humans and will save some bandwidth.
• generously allow CORS so we are able to use the generic HypermediaUi and basically allow other web clients to use the API.
• Add HypermediaExtensions for later use
• Add a basic GlobalExceptionFilter so we ensure that all exceptions are formatted nicely as ProblemJson
• Add a “404” response so if some route is accessed which does not exist we will provide a proper ProblemJson
