What did you expect to happen?

While attempting to implement the Yoast SEO package in a Node.js environment, I expected to be able to run it without errors.

What happened instead?

While attempting to run my own script (i.e. node index.js ), I was presented with the following error:

/Users/theuser/projectdir/node_modules/yoastseo/index.js:1
(function (exports, require, module, __filename, __dirname) { import { AnalysisWebWorker, AnalysisWorkerWrapper, createWorker } from "./src/worker";

SyntaxError: Unexpected token {

Please note: This issue occurs because the index.js file in the package does not get Bablified, but it should.

How can we reproduce this behavior?

• Create an empty, standalone environment in a new directory.
• Run yarn init and go through all the steps.
• Run yarn add yoastseo.
• Create a new file in the directory named index.js and paste the following code in the file:

// Altered the import to this to ensure compatibility with Node.
const { Paper, Researcher } = require( "yoastseo" );

const paper = new Paper( "Text to analyze", {
	keyword: "analyze",
} );
const researcher = new Researcher( paper );

console.log( researcher.getResearch( "wordCountInText" ) );

• Run node index.js.
• See error appear.
