In an effort to support all possible plugins and to keep size small, this extension uses ESLint plugins installed in the opened workspace folder(s). Due to restrictions in vscode, this extension does not support globally installed packages.
Does not support globally installed eslint plugin packages
ESLint v4.15.0 added an official location for rules to store a URL to their documentation in the rule metadata in eslint/eslint#9788. This adds the URL to all the existing rules so anything consuming them can know where their documentation is without having to resort to external packages to guess. If your plugin hasn't included this metadata, its possible you have an older version that needs to be updated.
When using the JS configuration file format, this extension currently only supports rules existing in a single exports object at the root (module.exports.rules).
