Keep your JS project lean by detecting duplicate dependencies
Diglett
Diglett is a command line tool that helps you detect packages with multiple versions in your JavaScript project. It is particularly useful for frontend apps where you want to keep the bundle size down.
Usage
By default diglett will ignore packages not imported by dependencies defined in the dependencies field of your package.json. If duplicate resolved packages found it will exit with code 1 and output the resolved versions:
Found 1 duplicate dependency
@material/animation with versions 3.1.0, 4.0.0.
npm projects
npx diglett npm <optional path to project>
Yarn projects
npx diglett yarn <optional path to project>
Yarn workspaces
npx diglett yarn-workspace <optional path to project> [--package <package name>]
By default all workspace packages are analyzed. If you just want to analyze one, pass the --package option with the package name – not folder name. It's possible to pass the --package option multiple times to analyze multiple packages.
