Automerge-CodeMirror

Automerge-CodeMirror brings collaborative editing to CodeMirror by linking it to an Automerge.Text object.

You can have as many Automerge.Text objects as you want inside a single Automerge document, and link each of them to a separate CodeMirror instance. This is useful for applications that render many editable text areas (such as a Trello-like application with multiple cards).

It ships with a React component, but can also be used without React.

Installation

npm install automerge-codemirror

To run it locally:

yarn storybook

General Usage

import { connectAutomergeDoc } from 'automerge-codemirror'

// Create a connect function linked to an Automerge document
const connectCodeMirror = connectAutomergeDoc(watchableDoc)

// Connect a CodeMirror instance
const getText = (doc) => doc.text
const disconnectCodeMirror = connectCodeMirror(codeMirror, getText)

// Disconnect the CodeMirror instance
disconnectCodeMirror()

React Usage

```typescript jsx import { connectAutomergeDoc, AutomergeCodeMirror } from 'automerge-codemirror'

// Create a connect function linked to an Automerge document const connectCodeMirror = connectAutomergeDoc(watchableDoc)

// Connect a CodeMirror instance const getText = (doc) => doc.text const acm = ( CodeMirror(element)} connectCodeMirror={connectCodeMirror} getText={getText} /> ) ```

Synchronisation with other peers

Automerge-CodeMirror is agnostic of how you choose to synchronize the linked Automerge document with other peers. Just register a handler with the WatchableDoc that does the synchronization.
