Allow cors on localhost

Question

I know it has kinda been answered already, but i don't understand how to fix my issue. I'm developing a static website using webpack 4, and i'm having issues when trying to load images (locally and from my online server).

How do you fix the Access to XMLHttpRequest at 'XXX' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource error when using webpack? I'm not using express (still learning webpack) and all the answers i find are quite a bit complicated for me and uses custom servers, which i don't..

Is there a simple method to bypass this?

By the way, i'm using <img src="XXX" alt="" crossorigin="anonymous"> with my images. Sometimes it works, sometimes it doesn't.. the articles i've found are way too technical for me at this point..

I've tried to add the following to my webpack.config.dev.js file, but it doesn't work either :

devServer: {
    headers: {
      'Access-Control-Allow-Origin': '*',
      'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, PATCH, OPTIONS',
      'Access-Control-Allow-Headers': 'X-Requested-With, content-type, Authorization',
    },
(...)
}

I think your images loaded from your online server cause the CORS warning and your webpack conf has nothing to do with it.

If you're using Chrome you can bypass CORS by using an extension like this or using Chrome's --disable-web-security argument explained as here
