Language Server Plugin for CodeMirror 6

This plugin enables code completion, hover tooltips, and linter functionality by connecting a CodeMirror 6 editor with a language server over WebSocket.

How It Works

Usage

npm i codemirror-languageserver

import { languageServer } from 'codemirror-languageserver';

const transport = new WebSocketTransport(serverUri)

var ls = languageServer({
    // WebSocket server uri and other client options.
    serverUri,
    rootUri: 'file:///',

    // Alternatively, to share the same client across multiple instances of this plugin.
    client: new LanguageServerClient({
        serverUri,
        rootUri: 'file:///'
    }),

    documentUri: `file:///${filename}`,
    languageId: 'cpp' // As defined at https://microsoft.github.io/language-server-protocol/specification#textDocumentItem.
});

var view = new EditorView({
    state: EditorState.create({
        extensions: [
            // ...
            ls,
            // ...
        ]
    })
});
