Loading Arcgis 3.25 and 4.8 at the same time

juanDavid — Wed, 15 Aug 2018 22:16:21 GMT

Hello, actually I have a very big app using 4.8 but now I need some functionality from 3.25 and I'm trying to load both at the same time but failed.

Here's a Sample of what I'm trying to do.

Arcgis problem

I extracted the code from this video:

You need to set up your dojoConfig like in the video, before the CDN script tag. You have it after the CDN script tag, so it doesn't get picked up.

  <script>
    window.dojoConfig = {
      async: true,
      packages: [
        {
          name: "esri4",
          location: "https://js.arcgis.com/4.8/esri"
        }
      ],
      has: {
          "dojo-preload-i18n-Api": false
      }
    }
  </script>
  <script src="https://js.arcgis.com/3.25/"></script>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This way you can reference 3x and 4x correctly.

Here is the demo from the video.

There are limitations, but you can do some stuff.

The sample is actually not working.

I just loaded it, seems to be working ok. I have a 3x map on top and a 4x 3d map on the bottom.

This solution does not work with API > 4.6.

I like to find a solution to use 3.21 / 3.28 and 4.11 in the same application... please share information if you know a solution.
