Bug report
Actual Behavior
When using eslint-webpack-plugin 4.1.0 with webpack 5.52.1, I pass an instance of the plugin object to webpack via the plugins array with the extensions option as follows:
plugins: [
new ESLintPlugin({
extensions: ['js', 'ts', 'jsx', 'tsx'],
}),
...
],
However, I receive the error:
[INFO] ERROR in [eslint] Invalid Options:
[INFO] - Unknown options: extensions
[INFO] - 'extensions' has been removed.
My project is using eslint 9.1.1. According to the documentation, it looks like the extensions field is no longer used, which I suspect is the cause of this error.
The most recent version with the extensions field is eslint 8.x.
According to the plugin's documentation on NPM:
You also need to install eslint >= 8 from npm, if you haven't already.
Expected Behavior
When using eslint-webpack-plugin 4.1.0 with webpack 5.52.1, I expect to be able to pass an instance of the plugin object to webpack via the plugins array with the extensions option set to lint the correct files.
How Do We Reproduce?
- Install
eslint-webpack-plugin 4.1.0,webpack 5.52.1, andeslint 9.1.1. - Pass an instance of
ESLintPlugin(even if theextensionsfield is not set, you should still see the error. I assume this is becauseextensionsis still passed to theESLintobject).
