import { join, resolve } from 'path';
import ESLintPlugin from 'eslint-webpack-plugin';
import { rootDir } from '../utils/env';

const config = {
  context: join(rootDir, '/src'),
  eslintPath: resolve('./.eslintrc'),
  extensions: ['js', 'jsx', 'ts', 'tsx'],
};

export const esLintPlugin = new ESLintPlugin(config);

Actual Behavior

The linter works because i get the linting error in the console but at the end of the build it just exits with the error above.

Expected Behavior

To finish linting with out getting the error at the end of the build. - sorry not sure what else i can put here.

Please paste the results of npx webpack-cli info here, and mention other relevant information

[ricardogobbosouza]

Hi @jhopley-stadion Sorry for delay...

Your configuration is wrong eslintPath: This is eslint executable path, not eslint configuration file

You can remove this line, by default the eslint will already read your configuration, but if you want to force it use overrideConfigFile

See https://eslint.org/docs/latest/integrate/nodejs-api
