if you use FLAT CONFIG, specify to checker

plugins: [
    checker({
      eslint: {
        useFlatConfig: true, // for me this fix the problem
        lintCommand: "eslint 'src/scripts/**/*.ts'", 
      },
    }),
  ],

useFlatConfig is not working for me. Still getting same error

checker({
        typescript: true,
        eslint: {
          useFlatConfig: true,
          lintCommand: 'eslint "./src/**/*.{ts,tsx}"',
        },
        overlay: {
          initialIsOpen: false,
        },
      }),

dependencies

"vite-plugin-checker": "^0.6.4",
"eslint": "^9.3.0",

Same issue.

[tryforceful]

Try now using "vite-plugin-checker": "0.7.0" @vishal-kadmos

Any updates?

It doesn't work with the ESLint 9.9.0 eslint.config.ts.

Using dev: { overrideConfig: { flags: ['unstable_ts_config'] } }, it simply ignores the flag. Using lintCommand: 'eslint --flag unstable_ts_config' it says "unknown --flag, do I mean --fix?"

Edit: Looking into the code the typing says there is a flags, but in the code it is not used for eslint. Only for the others like biome.

Seeing https://github.com/fi3ework/vite-plugin-checker/blob/b2c32367cf2e410154194d7730d8830aace898d9/packages/vite-plugin-checker/src/checkers/eslint/main.ts#L76C1-L78C13 Instead of

eslint = new FlatESLint({
    cwd: root,
})

it should be as example for a hardcoded flag

eslint = new FlatESLint({
    cwd: root,
    flags: ['unstable_ts_config']
});

sooo there is the interpreting of the flags option completely missing.

And for the buildmode it needs fixes here https://github.com/fi3ework/vite-plugin-checker/blob/b2c32367cf2e410154194d7730d8830aace898d9/packages/vite-plugin-checker/src/checkers/eslint/main.ts#L171-L179

Because the mentioned eslint.dev.eslint in the docs doesn't seem to exist for eslint. Only for biome.
