export async function initialize(container, connOptions = {}, renderOptions = {}) {
    const editor = new NodeEditor('retejs@0.1.0', container);

    editor.use(ConnectionPlugin, connOptions);
    editor.use(VueRenderPlugin, renderOptions);

    const engine = new Engine('retejs@0.1.0');
    
    editor.on('process nodecreated noderemoved connectioncreated connectionremoved', async () => {
        if(editor.silent) return;
        
        await engine.abort();
        await engine.process(editor.toJSON());
    });

    return {
        editor,
        engine,

initEditor() {
            this.editor = new NodeEditor(ID, this.$refs.area);
            this.engine = new Engine(ID);

            this.editor.use(VueRenderPlugin);
            this.editor.use(ConnectionPlugin);
            this.editor.use(AreaPlugin);
            this.editor.use(ContextMenuPlugin, { 
                delay: 100,
                allocate(component) {
                    return component.allocation || [];
                }
            });
            this.editor.use(ModulePlugin, {
                engine: this.engine,
                modules: this.$refs.modules.list
            });
