Jest throws: "SyntaxError: Unexpected token 'export'" with module: commonjs

Describe the bug possible related issue: https://github.com/alexcaza/export-to-csv/issues/87 I know that the new version of export-to-csv has some breaking change which exports ES modules instead of CommonJS now? But that caused our Jest to fail as it by default does not transform the ts files in export-to-csv. Is there a recommended approach to work this around? I saw this post: https://www.sobyte.net/post/2022-06/jest/ but looks like only option 2 is good for export-to-csv.🤔But it will lead to confusions.

To Reproduce Steps to reproduce the behavior: tsconfig.json: "compilerOptions": { "moduleResolution": "Node", "module": "CommonJS", } and package.json does NOT have "type": "module" as i am on commonjs.

Full error Jest encountered an unexpected token

Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.

Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.

By default "node_modules" folder is ignored by transformers.

Here's what you can do:
 • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it.
 • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript
 • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
 • If you need a custom transformation specify a "transform" option in your config.
 • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/configuration
For information about custom transformations, see:
https://jestjs.io/docs/code-transformation
