Using .js files inside Power BI custom visual

[DevForDay]

Is it possible to use .js files inside a custom visual? Every time I try to make .js files that contains React component i get the following error

Also if I rename file from .js to .tsx everything works fine. I tried to install babel and diffrent types of loaders but I get the same error.

HI @DevForDay,

You can take look at the following link about add external library support in custom visual:

This does not fix my problem. I Want to write my custom code and store it as .js file. This link is just an explanation for adding external libraries which does not fix my problem.
