复制代码

npm add @vue-flow/core

javascript 复制代码

npm install @vue-flow/background @vue-flow/minimap @vue-flow/controls

VueFlow 负责画布本体

nodes 负责节点数据

edges 负责连线数据

Background 负责网格背景

MiniMap 负责右下角缩略图

Controls 负责缩放、重置等控制

type

这是节点类型。

Vue Flow 里有默认类型，比如：

input：起始节点

output：结束节点

default：普通节点

it-view-on-init

这个参数表示：

页面初始化完成后，自动把画布内容缩放到合适的可视范围。
