@types/imurmurhash in dependencies, but didnt install imurmurhash itself (and no one reviewing noticed it in the PR). Our no-extraneous-dependencies rule in ESLint didnt catch this coz the type declarations were present. @types/ been installed in dev-dependencies, ESLint would have caught the missing dependency issue. Anyway to use to ESLint to check @types / packages are dev-dependencies and not dependencies ?
