Recommended rules violations are not reported with webpack and eslint-loader

[GaryB432]

Repro

webpack.config.js snippet

  module: {
    rules: [
      {
        test: /\.ts$/,
        loader: 'ts-loader',
      },
      {
        enforce: 'pre',
        test: /\.ts$/,
        exclude: /node_modules/,
        loader: 'eslint-loader',
        options: {
          formatter: FriendlyFormatter,
          parser: '@typescript-eslint/parser',
          extends: [
            'plugin:@typescript-eslint/recommended',
          ],
          plugins: ['@typescript-eslint'],
          // rules: { // works with rules like this
          //   'sort-keys': 2,
          //   '@typescript-eslint/explicit-function-return-type': 2,
          // },
          env: {
            browser: true,
            node: true,
          },
        },
      },
    ],
  },

const someObj = {
  b: 9,
  a: 4,  // member out of order
};

export function someNumber() { // no return type
  return undefined;
}

console.log(someNumber()!); // non-null assertion

Expected Result

All the violations of recommended rules would be reported

Actual Result

No violations are reported

Additional Info

The violations are reported if I spell out the rules in the webpack config's options.rules.

Repro repo is available on github

run npm build

an alternative title might be webpack config options.extends seems to be not working

[bradzacher]

This seems like an issue that belongs in the eslint-loader repo?

[GaryB432]

looks like they have an issue. webpack-contrib/eslint-loader#272

I guess I'll hold off on eslint@6 for now. Oh well.

I am updating my yeoman generator from tslint and wanted to be up-to-date GaryB432/generator-webpack-ts

[bradzacher]

Ahh so it's a KP in the loader. Good to know!

I'll close this issue then.
Thanks for bringing this to our attention.

Sorry, KP = Known Problem
