`DC-SDK` is based on the open source project `Cesium` for the second development of two three-dimensional `WebGis` application framework , the framework optimizes the use of `Cesium` and adds some additional features , designed for developers to quickly build `WebGis` application.

```warning
Tips：This SDK is JS+GIS framework package. Developers need to have some front-end technology and GIS related technology
```


## Run examples

```shell
  yarn run build
  yarn run server
```

## Installation

`NPM / YARN` **_`(Recommend)`_**

Installing with NPM or YARN is recommended and it works seamlessly with webpack.

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

```js
import DC from '@dvgis/dc-sdk/dist/dc.base.min'
import DcCore from '@dvgis/dc-sdk/dist/dc.core.min'
import DcChart from '@dvgis/dc-sdk/dist/dc.chart.min'
import DcMapv from '@dvgis/dc-sdk/dist/dc.mapv.min'
import DcS3M from '@dvgis/dc-sdk/dist/dc.s3m.min'
import '@dvgis/dc-sdk/dist/dc.core.min.css'
```

`NPM / YARN` **_`(On-demand)`_**

```shell
yarn add @dvgis/dc-base
yarn add @dvgis/dc-core
yarn add @dvgis/dc-chart
yarn add @dvgis/dc-mapv
yarn add @dvgis/dc-s3m
-------------------------
npm install @dvgis/dc-base
npm install @dvgis/dc-core
npm install @dvgis/dc-chart
npm install @dvgis/dc-mapv
npm install @dvgis/dc-s3m
```

```js
import DC from '@dvgis/dc-base'
import DcCore from '@dvgis/dc-core'
import DcChart from '@dvgis/dc-chart'
import DcMapv from '@dvgis/dc-mapv'
import DcS3M from '@dvgis/dc-s3m'
import '@dvgis/dc-core/dist/dc.core.min.css'
```

```

```
Please put the resources in the project root directory libs/dc-sdk, if you put it in other directory, the framework will not run properly.
```

## Configuration

> The configuration is mainly used in the `NPM / YARN` way

Since the `DC` framework sets `CESIUM_BASE_URL` to `./libs/dc-sdk/resources/` , you need to copy `Cesium` related static resources files: `Assets` , `Workers` , `ThirdParty `to `libs/dc-sdk/resources` directory of the project to ensure that the 3D scene can be rendered properly. You can also use `DC.baseUrl` to set the static resource base related to `Cesium` .

`Webpack`

[Project Template](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`

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

`Vue3.x`

[Project Template](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 = {
  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'),
          },
        ],
      },
    ])
  },
}
```


## Start

```js
global.DC = DC
DC.use(DcCore) // node
DC.ready(() => {
  let viewer = new DC.Viewer(divId) // divId is the Id attribute value of a div node. If it is not passed in, the 3D scene cannot be initialized
})
```
