Answer 1

module.exports = {
  ...
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: [
          {
            loader: 'ts-loader',
            options: {
              transpileOnly: true
            }
          }
        ]
      }
    ]
  }
}

Answer 2

use ignoreDiagnostics to ignore certain TypeScript errors, but this is more applicable when you just want to run code

{
  test: /\.tsx?$/,
  use: "ts-loader",
  options: {
    ignoreDiagnostics: [2322]
  }
},
