Jest: Cannot find module 'helmet' or its corresponding type declarations #435

Closed thorstenfleischmann closed 1 year ago

thorstenfleischmann commented 1 year ago

I try to run a ts-jest tests with supertest. The test fails with "Cannot find module 'helmet' or its corresponding type declarations".

helmet ^4.0.0 does not throw this error. Any idea what to look for?

Thanks so much.

What version of Helmet are you using?

Could you share some sample code that reproduces the problem?

thorstenfleischmann commented 1 year ago

I don't know exactly what happened. But I was able to fix the problem by separating tests with jsdom environment from tests with node environment (using jest projects). Somehow jsdom caused this problem.

Sorry for bothering ;-)
