Adding ignores to the typescript-eslint recommended configuration?

I'm trying to add an ignores object to the typescript-eslint configuration

I figured this would do the trick:

import eslint from "@eslint/js";
import tseslint from "typescript-eslint";

export default tseslint.config(
  eslint.configs.recommended,
  ...tseslint.configs.recommended,
).push({
  ignores: ["build/*"]
});

However when running npx eslint . it produces this error:

Oops! Something went wrong! :(

ESLint: 8.57.0

TypeError: All arguments must be objects.

How should we go about extending the configuration to add ignores?

config expects objects; push acts on arrays. Just add the additional rule object:

import eslint from "@eslint/js";
import tseslint from "typescript-eslint";

export default tseslint.config(
  eslint.configs.recommended,
  ...tseslint.configs.recommended,
  {
    ignores: ["build/*"]
  }
);
