A Visual Flow Editor Based on Vue And Antv/g6

Introduction

vue-visual-flowIt is based on antv/g6the configuration of the visualization routine implemented Vuecomponents

Project uses rolluppackaged, are provided cjs esmin two modular form to introduce ways, size is only about 100K

Design ideas

In order to remove the business logic as much as possible, the component shares the G6 instance, as well as the currently operating node and edge instance, for users to complete their own business logic externally

About G6 api: G6

Part of the problem and progress tracking

• Currently antv/g6there will be an updated version of the problem after the disappearance of custom graphics, it does not support the new antv/g6tracking Issue: G6-Issue

issue has been fixed, use antv/g6@3.7.3and above

• Currently does not support simultaneous node configuration settings tipsand anchor configuration labelNamecauses a problem can not be switched prompt information g6-issue

issue has been fixed, use antv/g6@3.8.1and above
