How to enable @typescript-eslint/no-floating-promises

[zecka]

I'm on nuxt3 and i try to enable following rule @typescript-eslint/no-floating-promises': 'error'

So i add it in eslint.config.js as follow

import antfu from '@antfu/eslint-config'

export default antfu({
  vue: true,
  rules: {
+    '@typescript-eslint/no-floating-promises': 'error',
  },
})

But now eslint stop working and i got following error in eslint console (vscode)

Error: Error while loading rule 'ts/no-floating-promises': You have used a rule which requires type information, but don't have parserOptions set to generate type information for this file. See https://typescript-eslint.io/getting-started/typed-linting for enabling linting with type information.
Parser: vue-eslint-parser
Note: detected a parser other than @typescript-eslint/parser. Make sure the parser is configured to forward "parserOptions.project" to @typescript-eslint/parser.

What's wrong with my eslint config ? how to allow using @typescript-eslint rules ?

Note: I ask the same question on @nuxt/eslint : nuxt/eslint#544

export default antfu({
  typescript: {
    filesTypeAware: ['**/*.ts', '**/*.tsx', '**/*.vue'],
  }
})

That can will make linting slow AF so use with caution, maybe as

import antfu, {isInEditorEnv} from '@antfu/eslint-config'

export default antfu({
  typescript: {
    filesTypeAware: isInEditorEnv() ? ['**/*.ts', '**/*.tsx', '**/*.vue'] : undefined,
  }
})

(may lead to longer saving) or the opposite way (may lead to longer cmd lint command)

Thank you for your response, but the same error is still appearing. At least on VS Code. Here is a repository to reproduce the issue:

Finaly make it work by adding fileTypeAware(suggested by @Dimava) and also parserOption.project

Here is the eslint.config.js

import antfu from '@antfu/eslint-config'

export default antfu({
  vue: true,
  rules: {
    "@typescript-eslint/no-floating-promises": "error"
  },
  typescript: {
+    parserOptions: {
+      project: "./tsconfig.json",
+    },
+    filesTypeAware: ['**/*.ts', '**/*.tsx', '**/*.vue'],
  },
})

And nuxt.config.ts

export default defineNuxtConfig({
  compatibilityDate: "2025-02-11"
})
