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.

yarn add @dvgis/dc-sdk
-------------------------
npm install @dvgis/dc-sdk
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)

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
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'

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

// 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

// 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

// 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

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
})
