+
+# 简介
+
+思维导图是一种常见的表达发散性思维的有效工具，市面上有非常多的工具可以用来画思维导图，百度一下，整页都是广告可供选择，此外也有一些可以用来帮助快速实现的`JavaScript`类库，如：[jsMind](https://github.com/hizzgdev/jsmind)、[KityMinder](https://github.com/fex-team/kityminder)。
+
+本文会介绍如何从头实现一个简易的思维导图。
+
+
+
+# 技术选型
+
+这种图形类的绘制一般有两种选择，`svg`与`canvas`，因为思维导图主要是节点与线的连接，使用与`html`比较接近的`svg`比较好操作，`svg`类库也有挺多，在试用了[svgjs](https://svgjs.dev/docs/3.0/)和[snap](http://snapsvg.io/)后，有些需求在`snap`里没有找到对应的方法，所以最终选择了`svgjs`，视图库使用的是`vue2.x`全家桶。
+
+
+
+# 数据结构
+
+这里主要指每个节点的数据结构，大概需要包含是否是根节点、节点层级、节点内容（包括文本、图片、图标等固定格式）、节点展开状态、子节点、父节点等等，此外还包括该节点的特定样式，用来覆盖主题的默认样式：
+
+```js
+
+```
+
+每次操作都会修改这份配置数据，然后整体刷新，有点数据驱动的意思，好处很明显，只用维护数据就行了，不用陷入对视图的操作。
+
+
+
+# 逻辑结构图
+
+思维导图常见的有几种变种，我们先看最基础的【逻辑结构图】如何布局，其他的可以在末尾小节查看。
+
+
+
+## 节点定位
+
+
+
+## 节点连线
+
+
+
+# 支持图片、图标
+
+
+
+# 展开收缩
+
+
+
+# 文字编辑
+
+# 拖动、放大缩小
+
+# 主题
+
+# 节点样式编辑
+
+# 快捷键
+
+快捷键就是监听了到特定的按键来执行特定的操作，包含单个按键和组合键，我们可以使用一个对象来保存快捷键和对应的命令，`key`代表按键，`value`代表要执行的命令，比如：
+
+```js
+const shortcutKeys = {
+	'enter': 'addSiblingNode',
+    'ctrl+b': 'bold'
+}
+```
+
+包含两种类型，单个按键、以`+`拼接的组合键，接下来只要监听`keydown`事件来检查即可，首先要说明的是组合键一般指的是`ctrl`、`alt`、`shift`
+
+
+
+# 实现过渡效果
+
+# 回退
+
+# 导入导出、其他格式
