Objectives

• Display the different layers related with income information in Spain, 2020.
• Allow the user to examine all different layers without exiting the application.
• When users switch to a different layer, the view extent shall be maintained.
• When users switch to a different layer, don't re-render the basemap layer.

Setup from scratch

• Use create-react-app to initialize a React app with NPM.

  npx create-react-app
  

• Esri Calcite Icons: https://github.com/Esri/calcite-components-examples/tree/master/react

  • Install Esri Calcite UI Icons https://esri.github.io/calcite-ui-icons

    npm install @esri/calcite-ui-icons
    

  • Install the ncp Node package, and add the postinstall and copy scripts to 'package.json'
  • Install Esri Calcite Components React This package includes the compatible version of the main component library as a dependency, so no need to install @esri/calcite-components separately.

    npm install @esri/calcite-components-react
    

  • Install the Calcite assets locally (this will copy the Calcite assets (the icons, basically) from "node_packages/@esri/calcite-components/dist/calcite/assets" into "public/assets")

    npm run copy
    

  • Install Toastify

    npm install react-toastify
    

  • Serve the app locally with:

  npm start
  

  • The app is automatically redeployed to Vercel upon Git pushes to the remote
  • The app relies on several environment variables with the URLs of the map and feature services.

• Todo

  ☞ In the legend, create a single object with the sublayer names in EN and ES
  ☞ Implement debouncing for click events
  ☞ Alerts about the possibility of clicking on a different location without closing the info table
  ☞ Show an info icon by the cursor when hovering over a queryable area
