Yarn

This week, the Yarn npm client was published. It’s an open-source project that builds on top of npm’s registry, replacing the default npm client with a faster, more reliable client. But before you hop on the new train, consider that some features like custom registries and private packages are still missing and that the concept of locking down dependencies is fundamentally different to bower’s or npm’s principles of dependency management. Therefore you should try it out and read the concept before using it in your projects.
