Best way to resolve circular dependencies in TypeScript

Question

I'm working on a simple API for a website in TypeScript, the code works well but I've a circular dependency that I need to fix.

A (very) minimal example of the project can be found here: https://codesandbox.io/s/dreamy-perlman-lpq6gh

Which is the best way to fix circular dependency of api/index.ts in this example?

I've tried to use an inherit class, but I don't know the best way to call a class child from another child.

Thanks!

No really. I thought about using a third file but I don't like that solution. Thanks anyway! — secdef, Sep 10 '22 at 05:14

Firstly run the following cli command to get a list of circular dependencies, then you will notice what to do: Further instruction for madge here

npx madge --circular --extensions ts ./

Well, according to madge, I don't have circular dependencies. But clearly in the codesandbox I am importing two files that import into each other. – secdef Sep 10 '22 at 05:18
then you have found the cyclic – jmvcollaborator Sep 10 '22 at 05:58
So cyclic dependencies and circular dependencies are not the same? – secdef Sep 10 '22 at 06:01
isnt a synonym? It isThanks! – jmvcollaborator Sep 10 '22 at 06:18
Thank you too. But I'm confused rn, they are synonym, but they are not the same. – secdef Sep 10 '22 at 06:26
