I tried to run the tests with npm test, but seems like there's no .eslintrc file, so eslint fails.

However, given that this is a TypeScript only issue, I'm not sure it'd do anything, even if the fix introduces problems, unless said file included configuration for the eslint-typescript plugin. Nevertheless, i'd be happy to run further tests if needed
