SyntaxError: Cannot use import statement outside a module

[GustavoEklund]

Importing fileTypeFromBuffer using ES6 module with Node + TypeScript + jest throws an error, am I doing something wrong? (I also tried importing fileTypeFromFile and give the same error)

(error throws only while importing modules from 'file-type' package, other packages haven't given any trouble)

● The test suite failed to run

    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.

    Details:

    /urs/src/app/node_modules/file-type/index.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){import * as strtok3 from 'strtok3';

This is a problem with Jest not properly supporting native ESM.
