Based on the information you provided, it looks like your config file is not being picked up for some reason. Configuration for globals looks correct and should work. In order to figure out what is going on, you should do two things. First you can run eslint --print-config path_to_some_js_file to see how your config looks like after ESLint resolves all dependencies and cascading. Most likely that config will not have globals declared. After that, you can run eslint --debug path_to_file to see all config files that are being used by ESLint. If your file is not being included, check all other config files and verify that they don't have root: true in them (which would prevent ESLint from merging configs in parent directories). For more information about CLI flags you can look at ESLint documentation
