From CommonJS to ES modules (ESM) in TypeScript 

The main drawback of transitioning to ESM (ECMAScript Modules) at the moment is the inability of jest.mock to mock ES modules without Babel: github.com/jestjs/jest/issues/10025

thanks buddy that worked really well

One thing that bothers me about modules is .js extension inside the import statement of the TS file. Another is that the pure esm library is not compatible with commonjs project, so I have to use an older version or skip that library and use a different one.

How can we migrate an existing project with large codebase as I don't want to edit each and every file
