When using azure-maps-control with Next.js 15.5.3 in a Turborepo monorepo, the build fails with the following error:
`Module parse failed: Identifier 'e' has already been declared (3644:109)
/node_modules/azure-maps-control/dist/atlas-esm.min.js
3644 | let [e, t, r, n] = param;
3645 | let i, o;
3646 | var a = ut((.2225045 * (e = ct(e)) + .7168786 * (t = ct(t)) + .0606169 * (r = ct(r))) / Qe), e = (e === t && t === r ? i = o = a : (i = ut(.4360747 * e + .3850649 * t + .1430804 * r) / Je), ...
`
This occurs as soon as the component imports:
import * as atlas from 'azure-maps-control';
Steps to Reproduce :
- Create a Turborepo monorepo using create-turbo.
- Add a Next.js app (next@15.5.3).
- Install Azure Maps:
npm install azure-maps-control
Add a simple map component:
`import { useEffect, useRef } from 'react';
import * as atlas from 'azure-maps-control';
export default function Map() {
const ref = useRef(null);
useEffect(() => {
if (!ref.current) return;
new atlas.Map(ref.current, {
authOptions: {
authType: atlas.AuthenticationType.subscriptionKey,
subscriptionKey: process.env.NEXT_PUBLIC_AZURE_MAPS_KEY!,
},
});
}, []);
return <div ref={ref} style={{ height: 500 }} />;
}
`
Run npx next dev.
Expected behavior
The Azure Maps SDK should build and run without syntax errors under modern bundlers like Next.js Webpack/Turborepo.
Actual behavior
Webpack parsing fails on atlas-esm.min.js with the error above.
