In this article, we will look at how we can call C# functions from a JS library in Blazor WASM. This can be useful to integrate with existing JS libraries that react to different events. This article is a continuation of a project made in our other article Wrapping JavaScript libraries in Blazor WebAssembly. We will recap what we did in this project first. But if you wish to follow the code examples yourself then it’s recommended to read that article first.

Recap

In the previous article, we made a wrapper for the JS library Popper, which we could parse a typed parameter that fitted the signature for the constructor for the library. This included specifying JSON names for the different fields when serializing and creating a custom serializer that can serialize enums using Description attributes. This left us with the following view which is the result of us constructing the popper from C#.
