arcgis-js-api @types

[JesseAdams]

Hello,

I'm trying to utilize Angular CLI with the with newest version of the JS API (4.9) along with Typescript and @types/arcgis-js-api (4.9.0).  I'm running into a build issue that can be repeated on multiple machines.  There appears to an issue with the "AbortSignal" variable in the typescript definition file.  Here is the error thrown:

I can get around this issue by commenting out the AbortSignal variable in the definition file:

However, this doesn't help during automated builds.

Is this a bug with typescript definition file?  Any suggestions would be greatly appreciated.

Thank you,

Try updating to the latest version of TypeScript in your application per this post in this thread.

I think the ng-cli comes with an older version of TS by default.

That worked to upgrade to Typescript 2.9 and Angular CLI version 6.x.

Thank you!
