The samples in this repo extend those provided by Esri. The samples integrate the @arcgis/core build of the ArcGIS API for JavaScript with various frameworks, module bundlers and build tools.
Install the modules into your project:
npm install @arcgis/coreThen use import statements to load individual modules.
import EsriMap from '@arcgis/core/Map';
import MapView from '@arcgis/core/views/MapView';
const map = new EsriMap({
basemap: "topo-vector"
});
const view = new MapView({
container: "viewDiv",
map: map
});Make sure to copy the API’s assets, which includes styles, images, fonts, and localization files from the @arcgis/core/assets folder to your build directory. A simple way to accomplish this is to configure an NPM script that runs during your build process. For example, use npm to install ncp and configure a script in package.json to copy the assets folder. Here’s a React example:
// package.json
{
"scripts": {
"copy": "ncp ./node_modules/@arcgis/core/assets ./public/assets",
"postinstall": "npm run copy",
...
},
}The final step is to set up the CSS. Choose a theme and then configure your code to copy the theme files from @arcgis/core/assets/esri/themes/ into your project. Here’s a React example:
// React - index.js
import '@arcgis/core/assets/esri/themes/dark/main.css';
