What is the best way to troubleshoot and resolve TypeScript errors related to Angular in d.ts files, especially when working

I've integrated Msal (https://github.com/AzureAD/microsoft-authentication-library-for-js) with the latest setup in Angular using Typescript 3.1.1, and I encountered the following error:

ERROR in node_modules/msal/lib-commonjs/UserAgentApplication.d.ts(35,9):
error TS2717: Subsequent property declarations must have the same type.
Property 'callBackMappedToRenewStates' must be of type 'any', but here has type '{}'.

Upon inspecting the code in the node module, it's apparent where the issue lies. However, I'd prefer not to modify this file or create a custom typing file just for this problem. Any suggestions on how to handle this?

Answer №1

Using the skipLibCheck property in tsconfig allows for skipping type checking in declaration files. This workaround is temporary until the msal issue is resolved - although it does suppress errors from all packages, which may not be ideal.

Answer №2

Make sure you are using the correct version of Typescript with this library.

If you have confirmed that you are using the right version, you can bypass Typescript errors by using // @ts-ignore or declaring variables as any, then patiently wait for a resolution.
