## Setup

### Create an Vue Application

You can use [`Vue CLI`](https://github.com/vuejs/vue-cli) to setup your Vue 2 applications.To install Vue CLI use the following commands.

```bash
npm install -g @vue/cli
vue create quickstart
cd quickstart
npm run serve
```
Initiating a new project prompts us to choose the type of project to be used for the current application. Select the option `Default ([Vue 2] babel, eslint)` from the menu.

### Adding Syncfusion Diagram package

All Syncfusion Vue packages are published in [npmjs.com](https://www.npmjs.com/~syncfusionorg) registry. To install Vue diagram package, use the following command.

```bash
npm install @syncfusion/ej2-vue-diagrams --save
```

### Registering Diagram Component

You can register the Diagram component in your application by using the **Vue.use()**. Refer to the code example given below.

```typescript
import { DiagramPlugin } from '@syncfusion/ej2-vue-diagrams';

Vue.use(DiagramPlugin);
```

> Registering **DiagramPlugin** in vue, will register the diagram component along with its required child directives globally.

### Adding CSS references for Diagram

Add CSS references needed for Diagram in **style** section of the **App.vue** file from **../node_modules/@syncfusion** package folder.

```html
<style>
@import "../node_modules/@syncfusion/ej2-diagrams/styles/material.css";
@import "../node_modules/@syncfusion/ej2-vue-diagrams/styles/material.css";
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-navigations/styles/material.css";
</style>
```

## Add Diagram Component

Add the Vue Diagram by using **ejs-diagram** selector in **template** section of the **App.vue** file.

```html
<template>
    <div id="app">
        <ejs-diagram id="diagram"  :width='width' :height='height' :nodes='nodes' :connectors='connectors'></ejs-diagram>
    </div>
</template>
<script>
import Vue from "vue";
import { DiagramPlugin } from "@syncfusion/ej2-vue-diagrams";

Vue.use(DiagramPlugin);

//Initializes the nodes for the diagram
let nodes: NodeModel[] = [
  {
    id: "begin",
    height: 60,
    offsetX: 300,
    offsetY: 80,
    shape: { type: "Flow", shape: "Terminator" },
    annotations: [
      {
        content: "Begin"
      }
    ]
  },
  {
    id: "process",
    height: 60,
    offsetX: 300,
    offsetY: 160,
    shape: { type: "Flow", shape: "Decision" },
    annotations: [
      {
        content: "Process"
      }
    ]
  },
  {
    id: "end",
    height: 60,
    offsetX: 300,
    offsetY: 240,
    shape: { type: "Flow", shape: "Process" },
    annotations: [
      {
        content: "End"
      }
    ]
  },
];
//Initializes the connector for the diagram
let connectors: ConnectorModel[] = [
  { id: "connector1", sourceID: "begin", targetID: "process" },
  { id: "connector2", sourceID: "process", targetID: "end" },
];

export default {
  data() {
    return {
       width: "100%",
       height: "350px",
       nodes: nodes,
       connectors: connectors
    };
  },
}
</script>
<style>
@import "../node_modules/@syncfusion/ej2-diagrams/styles/material.css";
@import "../node_modules/@syncfusion/ej2-vue-diagrams/styles/material.css";

## Key Features

- [Nodes](https://ej2.syncfusion.com/vue/demos/#/material/diagram/node.html)  - Nodes are used to host graphical objects (path or controls) that can be arranged and manipulated on a diagram page. Many predefined standard shapes are included. Custom shapes can also be created and added easily.
- [Connectors](https://ej2.syncfusion.com/vue/demos/#/material/diagram/connector.html) - The relationship between two nodes is represented using a connector.
- [Labels](https://ej2.syncfusion.com/vue/demos/#/material/diagram/annotation.html)- Labels are used to annotate nodes and connectors.
* [Ports](https://ej2.syncfusion.com/vue/demos/#/material/diagram/port.html) - Ports act as the connection points of the node and allows to create connections with only those specific points.
- [Interactive Features](https://ej2.syncfusion.com/vue/demos/#/material/diagram/drawing-tool.html) - Interactive features are used to improve the run time editing experience of a diagram.
- [Data Binding](https://ej2.syncfusion.com/vue/demos/#/material/diagram/local-data.html) - Generates diagram with nodes and connectors based on the information provided from an external data source.
- [Commands](https://ej2.syncfusion.com/vue/demos/#/material/diagram/keyboard-functions.html) - Supports a set of predefined commands that helps edit the diagram using keyboard. It is also possible to configure new commands and key combinations.
- [Automatic Layout](https://ej2.syncfusion.com/vue/demos/#/material/diagram/hierarchical-model.html) - Automatic layouts are used to arrange nodes automatically based on a predefined layout logic. There is built-in support for organizational chart layout, hierarchical tree layout, symmetric layout, radial tree layout, and mind map layout.
- [Overview Panel](https://ej2.syncfusion.com/vue/demos/#/material/diagram/overview.html) -  The overview panel is used to improve navigation experience when exploring large diagrams.
- [SymbolPalettes](https://ej2.syncfusion.com/vue/demos/#/material/diagram/symbol-palette.html) - The symbol palette is a gallery of reusable symbols and nodes that can be dragged and dropped on the surface of a diagram.
- [Rulers](https://ej2.syncfusion.com/vue/demos/#/material/diagram/drawing-tool.html) - The ruler provides horizontal and vertical guides for measuring diagram objects in diagram control.
- [Serialization](https://ej2.syncfusion.com/vue/demos/#/material/diagram/serialization.html) - When saved in JSON format a diagram’s state persists, and then it can be loaded back using serialization.
- [Exporting and Printing](https://ej2.syncfusion.com/vue/demos/#/material/diagram/print-export.html) - Diagrams can be exported as .png, .jpeg, .bmp, and .svg image files, and can also be printed as documents.
