ArcGIS for Javascript on ASP.NET Core project

MeloiMagpantay — Thu, 06 Jan 2022 11:41:05 GMT

Is there a way to use ArcGIS Javascript on ASP.NET Core website. I've been trying to use it but it is causing an error like this.

I tried to follow the get started documentation.

Well, I haven't used ASP in years, so I spun up a new project locally and it looks like the default app uses a local jquery and bootstrap. This is where the error comes from because jquery has a require method it uses. We can work around this in the "Pages/Shared/_Layout.cshtml" file with a dojoConfig to define where the local packages can be loaded from.

Then in your "wwwroot/js/site.js" file, when you load the JSAPI and require the modules, you can load the jquery and bootstrap stuff.

require([ "esri/WebMap", "esri/views/MapView", "jquery", "bootstrap" ], function (...) {...})

This fixed the issue in my local app, should fix the issue for you too. Now I feel like I should do something with dotnet...

where should i write the code for map load code.in site.js. write the code like below.

function showMap() {
require([
"esri/config",
"esri/Map",
"esri/views/MapView",
"esri/layers/FeatureLayer",
"jquery",
"bootstrap"
], function (esriConfig, Map, MapView, FeatureLayer) {
const map = new Map({ basemap: "arcgis-topographic" });
const view = new MapView({
container: "viewDiv",
map: map,
center: [-118.80543, 34.02700],
zoom: 13
});

//Trailheads feature layer (points)
const trailheadsLayer = new FeatureLayer({
url: "https://services3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Trailheads/FeatureServer/0"
});

map.add(trailheadsLayer);

//Trails feature layer (lines)
const trailsLayer = new FeatureLayer({
url: "https://services3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Trails/FeatureServer/0"
});

map.add(trailsLayer, 0);
});
}

We are also getting the same issue. While we are using the version "https://js.arcgis.com/4.26/".

Did you find any fix for this

Thanks.

The way to get around this error is to comment out this section of your shared _layout.cshtml view

It appears to conflict with any arcgis sdk of higher than 4.15
