Auth0 node package doesn't work unless I add "DOM" to my "lib" array in tsconfig. Why do I need to do this for purely backend service?

Question

I have a nodejs backend service, and I want to use the auth0 management API to do some things like manually creating users.

Unfortunately, this library doesn't work unless I add "DOM" to my tsconfig.json.

Otherwise, I get the following errors:

Is there some way I can avoid adding DOM to my tsconfig?

Answer 1

Unfortunately, the auth0 package depends on the Response interface, which is defined in the dom lib.

You either have to add dom to the lib array, or specify skipLibCheck: true in compilerOptions. According to the TypeScript documentation:

Rather than doing a full check of all d.ts files, TypeScript will type check the code you specifically refer to in your app’s source code.

Check this answer for more details about the pros/cons of using skipLibCheck.
