I'm working on an Electron app with React and I'm using Typescript, Webpack, Babel and ESLint. And for some reason I get in my main.js file, which is my bundled file, the following line:
try {
// Optional dependency (as in, doesn't need to be installed, NOT like optionalDependencies in package.json)
// eslint-disable-next-line import/no-extraneous-dependencies
const supportsColor = __webpack_require__(/*! supports-color */ "./node_modules/supports-color/index.js");
if (supportsColor && (supportsColor.stderr || supportsColor).level >= 2) {
exports.colors = [
Which triggers the following error when I run npm run lint:
> biomech@1.0.0 lint
> eslint .

I don't know where the eslint-disable-next-line import/no-extraneous-dependencies line is coming from. If it's from Webpack, or Babel, or something else. But I don't think I actually need it since I never even typed a rule regarding extraneous dependencies. I tried adding an empty rule to the .eslintrc just so that it would at least make sense but I couldn't find anything regarding no-extraneous-dependencies in the ESLint docs, so I could never add it.
The eslint . command will run the linting on all the files including the bundled scripts files too. You should add .eslintignore file and ignore the files on which you wish to run the lint.
In your case ignore add **/*.js to tell eslint ignore linting .js files.
