Typescript eslint - Missing file extension “ts” import/extensions

Question

I have a simple Node/Express app made with Typescript. And eslint give me the error

Missing file extension "ts" for "./lib/env" import/extensi         


        

Answer 1

Add the following code to rules:

"rules": {
   "import/extensions": [
      "error",
      "ignorePackages",
      {
        "js": "never",
        "jsx": "never",
        "ts": "never",
        "tsx": "never"
      }
   ]
}

airbnb ESLint config leads the problem.
