IntelliSage is a standalone Blazor API served through an iframe as a purely clientside solution for intellisense in the Monaco editor.
The Blazor app is compiled as a standalone website running WASM--no backend involved. This is hosted statically at any CDN. This repo is synced with a deployed site with the published contents and is open to use from the public as an interface: https://intellisage.vercel.app/ The web app's main work is done in a WebWorker with some further optimizations around JS <-> WASM marshalling to provide non-blocking behavior for the consumer while working in the Monaco editor.
A demo site with a Monaco editor can be found here: https://intellisage-demo.vercel.app/ The demo's repo can be found here: https://github.com/knervous/intellisage-demo
If you want to use this in an existing JS client that uses Monaco, integration is simple. Look at the example listed under Examples/client. The interface itself is all in monaco.js which is framework-independent, i.e. works in React, Angular, Vue, vanilla js. The pattern is as follows:
import { MonacoService } from "./monaco";
const monacoService = new MonacoService();
// Somewhere later in the code when we have a reference to `monaco` whose language is `csharp`
await monacoService.initialize(monaco, /** optional param for another URL other than the default https://intellisage.vercel.app */)
// monaco instance is now wired up to csharp intellisense!Much of this project was bootstrapped with existing projects, notably https://github.com/Apollo3zehn/MonacoBlazorSample which laid the foundation for interacting with OmniSharp and Roslyn
