emotion-js on Create React App - 'jsx' is defined but never used

Question

So I tried to use emotion-js for the first time and get hooked by the css prop feature.

While trying what the documentation says I get a warning from the eslint.

'jsx' is defined but never used @typescript-eslint/no-unused-vars

The script that I use looks like this.

import React from "react";
//** @jsx jsx */
import { jsx } from "@emotion/core";

export const Component = () => {
    return (
        <div css={{color: red}}>
            This is a component
        </div>
    )
}

I'm using VSCode, so I can see that this import is tagged as never used. (Has transparent color)

But I did use it for my div, and if I remove the import, my css prop is showing an error.

Please help as to how to avoid this eslint warning, or at least make the VSCode recognize that jsx is being used.

Thanks!

Edit 2: I tried adding .eslintrc file that looked like this

{
  "parser": "@typescript-eslint/parser",
  "plugins": ["@typescript-eslint"],
  "extends": ["plugin:@typescript-eslint/recommended"],
  "rules": {
    "@typescript-eslint/no-unused-vars": [
      2,
      { "vars": "all", "args": "all", "varsIgnorePattern": "^jsx$" }
    ]
  }
}

Still get the warning, did I do it wrong?

Answer 1

Emotion provides its own eslint plugin that should handle this automatically for you.

Another approach is to use emotion's babel plugin to automatically add the jsx import and jsx pragma comment automatically at compile time. This way, you no longer need to add them in each of your file.
