openlayers-5.3.0 create react app

Hi.

I’m trying to integrate this js into a project but when I import the library I get a lot of errors like:

./src/OSMBuildings-OL5.js

  Line 859:9:    Expected an assignment or function call and instead saw an expression  no-unused-expressions

Search for the keywords to learn more about each error.

It’s a create react app project, but it should work I think.

thanks

From what I see code did not get properly transpiled into ES6. Ideally you could fine tune this process.

Resulting tasks would be refactoring to a modern code base + providing an npm module.

It works perfectly in standalone app.I’m going to make an example
