Is there a way to make ESLint understand the new import assertion syntax without adding Babel?

Question

Since the import assertion syntax (e.g. assert {type: 'json'}) is mandatory in the latest Node.js versions, I'm looking for a way to be able to write this new syntax, but I don't want to add Babel just to be able to use the Babel ESLint parser which understands it.

Could this be added by a different ESLint plugin?

Answer 1

You have to use the babel eslint parser for that

npm i -D @babel/eslint-parser @babel/plugin-syntax-import-assertions

then in .eslintrc

  "parser": "@babel/eslint-parser",
  "parserOptions": {
    "requireConfigFile": false,
    "babelOptions": {
      "plugins": [
        "@babel/plugin-syntax-import-assertions"
      ]
    }
  },
