> DC-SDK 是基于 Cesium 进行二次开发的2、3D一体 WebGis 应用框架,该框架优化了 Cesium 的使用方式和增添了一些额外功能，旨在为开发者快速构建 WebGis 应用。

```warning
Tips：本框架是 JS+GIS 的框架包。开发者需要有一定的前端技术和 GIS 相关技术
```

## 安装

`NPM / YARN` **_`(推荐使用)`_**

NPM / YARN 的方式安装，它能更好地和 `webpack` 打包工具配合使用。

```shell
yarn add @dvgis/dc-sdk
-------------------------
npm install @dvgis/dc-sdk
```

```js
import DC from '@dvgis/dc-sdk/dist/dc.base.min' //基础包
import DcCore from '@dvgis/dc-sdk/dist/dc.core.min' //核心包
import DcChart from '@dvgis/dc-sdk/dist/dc.chart.min' //chart包
import DcMapv from '@dvgis/dc-sdk/dist/dc.mapv.min' //mapv包
import '@dvgis/dc-sdk/dist/dc.core.min.css' // 主要样式
```

`NPM / YARN` **_`(按需安装)`_**

```shell
yarn add @dvgis/dc-base
yarn add @dvgis/dc-core
yarn add @dvgis/dc-chart
yarn add @dvgis/dc-mapv
-------------------------
npm install @dvgis/dc-base
npm install @dvgis/dc-core
npm install @dvgis/dc-chart
npm install @dvgis/dc-mapv
```

```js
import DC from '@dvgis/dc-base' //基础包
import DcCore from '@dvgis/dc-core' //核心包
import DcChart from '@dvgis/dc-chart' //chart包
import DcMapv from '@dvgis/dc-mapv' //mapv包
import '@dvgis/dc-core/dist/dc.core.min.css' // 主要样式
```

```

```
请将 resources 放置工程根目录 libs/dc-sdk 下，如果放置到其他目录下，框架将无法正常运行
```

## 配置

> 配置主要用于 `NPM / YARN` 的方式

由于 DC 框架中将 `CESIUM_BASE_URL` 设置为 `JSON.stringify('./libs/dc-sdk/resources/')`，这样需将 `Cesium` 相关的静态资源文件: `Assets`、`Workers` 、`ThirdParty` 复制到工程的 `libs/dc-sdk/resources` 目录下以保证三维场景能够正常呈现

`Webpack`

[工程模板](https://github.com/cavencj/dc-vue-app)

```js
// webpack.config.js

const path = require('path')
const CopywebpackPlugin = require('copy-webpack-plugin')
const dvgisDist = './node_modules/@dvgis'

module.exports = {
  plugins: [
    new CopyWebpackPlugin([
      {
        from: path.join(dvgisDist, 'dc-sdk/dist/resources'),
        to: 'libs/dc-sdk/resources',
      },
    ]),
  ],
}
```

`Vue2.x`

[工程模板](https://github.com/dvgis/dc-vue)

```js
// vue.config.js

const path = require('path')
const CopywebpackPlugin = require('copy-webpack-plugin')
const dvgisDist = './node_modules/@dvgis'

module.exports = {
  // 其他配置
  chainWebpack: (config) => {
    config.plugin('copy').use(CopywebpackPlugin, [
      [
        {
          from: path.join(dvgisDist, 'dc-sdk/dist/resources'),
          to: 'libs/dc-sdk/resources',
        },
      ],
    ])
  },
}
```

`Vue3.x`

[工程模板](https://github.com/dvgis/dc-vue-next)

```js
// vue.config.js

const path = require('path')
const CopywebpackPlugin = require('copy-webpack-plugin')
const dvgisDist = './node_modules/@dvgis'

module.exports = {
  // 其他配置
  chainWebpack: (config) => {
    config.plugin('copy').use(CopywebpackPlugin, [
      {
        patterns: [
          {
            from: path.join(dvgisDist, 'dc-sdk/dist/resources'),
            to: path.join(__dirname, 'dist', 'libs/dc-sdk/resources'),
          },
        ],
      },
    ])
  },
}
```


## 开始

```js
global.DC = DC
DC.use(DcCore) // Node 方式
DC.ready(() => {
  let viewer = new DC.Viewer(divId) // divId 为一个div节点的Id属性值，如果不传入，会无法初始化3D场景
})
```
