Tips for personalizing the error message displayed on Webpack's overlay

Is there a way to personalize the error overlay output message in order to hide any references to loaders, as shown in this image:

Any suggestions on how to remove the line similar to the one above from the overlay output?

Answer №1

Through my investigation in reverse engineering, I discovered that the culprit behind the display of the information is none other than `webpack-dev-server` itself. Unfortunately, there doesn't seem to be a built-in setting or option to modify this behavior. In order to address this issue, I resorted to implementing a workaround by extending the overlay's `showMessage()` method and removing the initial two lines that contain loader paths. Here is the snippet of the workaround I came up with:

const overlay = require('webpack-dev-server/client/overlay');
const show = overlay.showMessage;
overlay.showMessage = function (messages) {

  const newMessages = messages.map(
     msg => msg
      .split('\n')
      .slice(2)
      .join('\n')
  );

  show(newMessages);
};
