Discussion on: How to setup a React.JS Project with TypeScript, ESLint and Prettier

[Martin Cerny]

I had to add this to .eslintrc.js

    "import/extensions": [
       "error",
       "ignorePackages",
       {
         "js": "never",
         "jsx": "never",
         "ts": "never",
         "tsx": "never"
       }
    ],
    "react/jsx-filename-extension": [1, { "extensions": [".js", ".ts", "tsx"] }],

Any idea why you didn't need this?

I Martin Cerny, thanks by observation.

I had added this line also. This can be saw in shared source code at the end of post, but i forgot to add in example.

I will add this line.

Best regards

Thanks for updating the article! You should also add the other line jsx-filename-extension and then it also needs import resolver
