Fenris.OneOfContrib.Blazor 0.1.13-alpha

Fenris.OneOfContrib.Blazor

A collection of Blazor components for working with OneOf types in your Blazor project.

🤔 Why?

I was working on a project where I needed to render different components based on the value of a OneOf. I couldn't get the OneOf.Switch() method to work in Blazor, and writing switch statements over and over again was annoying and looked messy.

Instead I made a component library, which is actually just a switch statement in disguise, and found it made my Blazor components much more readable and in general nicer to work with.

⭐ Features

• Blazor components for OneOf types with up to 8 type parameters.
• Blazor components for types that inherit from OneOfBase, also with up to 8 type parameters.

That's it. It's a pretty simple library 😁

💿 Installation

Install the Fenris.OneOfContrib.Blazor NuGet package.

dotnet add package Fenris.OneOfContrib.Blazor

🚀 Usage

See the Examples project for a full, simple example.

Let's make a small example where we have to deal with a OneOf<string, int>.

First, add the using either to your _Imports.razor file, or directly in your specific pages/components:

@using Fenris.OneOfContrib.Blazor.Components

Then use the component in your blazor pages or components

<OneOfSwitch2 Value="myOneOf">
    <T0Template>
        <p>It's a string and the value is @context!</p>
    </T0Template>
    <T1Template>
        <p>It's an int and the value is @context!</p>
    </T1Template>
</OneOfSwitch2>

@code {
    private OneOf<string, int> myOneOf = "Hello World!";
}

If you are using a OneOfBase type, you need to use the <OneOfBaseSwitch2> component instead. Everything else is identical.

If your union contains more than two types, you need to use the <OneOfSwitchN> or <OneOfBaseSwitchN> components, where N is the number of types in your union. E.g. <OneOfSwitch5>
