**_`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
```
## 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 '@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
-------------------------
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'
import DcCore from '@dvgis/dc-core'
import DcChart from '@dvgis/dc-chart'
import DcMapv from '@dvgis/dc-mapv'
import '@dvgis/dc-core/dist/dc.core.min.css'
```
`CDN`
[Resources](https://github.com/dvgis/dc-sdk/releases)
```html
```
```
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 `JSON.stringify('. /libs/dc-sdk/resources/')`, you need to copy `Cesium` static resource files: `Assets`, `Workers`, `ThirdParty` to the `libs/dc-sdk/resources` directory of the project to ensure that the 3D scene can be rendered properly.
`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
})
```
