V9 issues with jest and typescript

[Fredsters]

Hi, I updated from 8.3.1 to 9.0.9.
My tsconfig:
"target": "ES2022", "module": "commonjs",
I face some issues now.

1. When trying to run my app, I got an error: "file ending .ts not supported" for the file where I use redis-smq. Solved by using tsx instead of tsc. Server runs.
2. When I tried to execute jest tests I got the same error, I solved it by adding redis-smq as exception in the transform step of jest. Usually node modules are not transformed. But it needed transformation
3. The tests start now, but I still get errors during test execution with my application framework.
   Cannot set property strategy of #<Object> which has only a getter
   So somehow the app framework has issues now that I use the version 9. I tried mocking stuff away and got some steps further but finally I need some functionality from the app framework in the test that I can't mock.

So my question. Did anything change from version 8.3.1 to 9.0.9 in terms of typescript/modules/dependencies/export. I don't know what.
Or is it even the case that commonjs is not supported anymore? Do you have any idea?

Hello,

I want to clarify that RedisSMQ itself does not throw the error "file ending .ts not supported." Both ESM and CommonJS are fully supported.

Upon reviewing the changes from v8 to v9 regarding TypeScript and module exports, it appears that there haven’t been any modifications in that regard.

It's important to note that Jest typically does not transform files within node_modules, which can sometimes lead to unexpected errors. I suspect the issue may stem from a configuration mismatch between Jest and TypeScript in your application.

Could you please provide sample code that reproduces the issue?

Hi, thanks for your answer. I got the test running by mocking redis-smq and app framework completely. I probably won't have time to provide sample code.

Still thanks for your answer :)
