Usage

You'll need the following:

• MirrorSharp.AspNetCore on the server (MirrorSharp.Owin if .NET Framework)
• mirrorsharp.js — client library that provides the user interface

Server

MirrorSharp.AspNetCore

Install-Package MirrorSharp.AspNetCore

If using Endpoint Routing (3.0+ only):

app.UseEndpoints(endpoints => {
    // ...
    endpoints.MapMirrorSharp("/mirrorsharp");
});

If not using Endpoint Routing:

app.MapMirrorSharp("/mirrosharp");

MirrorSharp.Owin

Install-Package MirrorSharp.Owin

In your Startup:

app.MapMirrorSharp("/mirrosharp");

Client

Library	Type	NPM
mirrorsharp-codemirror-6-preview	Latest
mirrorsharp	Stable

npm install mirrorsharp-codemirror-6-preview --save

Note: The name is temporary — once all testing on 6-preview is completed, it will become mirrorsharp 3.

Breaking Changes

Version mirrorsharp-codemirror-6-preview (future mirrorsharp 3.0+) includes a number of breaking changes — see migration-from-2.md for the full migration guide.

Build

Since mirrorsharp JS files are not bundled, you'll need to use a bundler such as Webpack, Parcel or ESBuild.

You can see a Parcel example in AspNetCore.Demo.

Note that mirrorsharp is written in TypeScript, and the package includes full TypeScript types.

Note: You need to manually require/import mirrorsharp/mirrorsharp.css into your bundle.

Usage

import mirrorsharp from 'mirrorsharp-codemirror-6-preview';

mirrorsharp(container, { serviceUrl: 'wss://your_app_root/mirrorsharp' });

If you're not using HTTPS, you'll likely need ws:// instead of wss://.

Note that the container is an actual HTML element, and not a CSS selector.

API

TODO. In general the idea is that "it just works", however customization is a goal and some options are already available.

Demos

You can check out the demos if you clone the repository locally.
After cloning, run ms setup to build and prepare everything.

Testing

TODO, but see MirrorSharp.Testing on NuGet.
