Implementation should ideally been straightforward. As I could simply have made a client adapter that modifies an internal string.
class HeadlessAdapter implements IEditorAdapter {
protected _content: string;
constructor() {
this._content = "";
}
on(): void {
return;
}
off(): void {
return;
}
registerUndo(): void {
return;
}
registerRedo(): void {
return;
}
deregisterUndo(): void {
return;
}
deregisterRedo(): void {
return;
}
getCursor(): ICursor | null {
return null;
}
setCursor(): void {
return;
}
setOtherCursor(): IDisposable {
return {
dispose: () => {
return;
},
};
}
getText(): string {
return this._content;
}
setText(text: string): void {
this._content = text;
}
setInitiated(): void {
return;
}
applyOperation(operation: IPlainTextOperation): void {
if (!operation.isNoop()) {
return;
}
this._content = operation.apply(this._content);
}
invertOperation(operation: IPlainTextOperation): IPlainTextOperation {
return operation.invert(this._content);
}
dispose(): void {
return;
}
}
const headlessAdapter = new HeadlessAdapter();
const firebaseAdapter = new FirebaseAdapter(dbRef, 0, "#000000", "Admin");
const opts = <IFirepadConstructorOptions> {
userId: 0,
userColor: "#000000",

};
const firepad = new Firepad(firebaseAdapter, headlessAdapter, opts);Unfortunately this errors out with the following
