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 272:9:    Expected an assignment or function call and instead saw an expression  no-unused-expressions
  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

Sounds familiar.
Can you confirm the library works standalone?
Also, could you provide a running sample with your setup? Demo URL, CodePen etc.

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

[All4Gis]

I created a sample repository

npm install and npm start

[kekscom]

git checkout OSMBuildings

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.

Okay, I shall enquire and I'll try to make a working example. thanks

[All4Gis]

I've finally had time to make some changes. It's working.
Here is a link to the example.
