Collects anonymous nodejs module version upgrade statistics. Helps you decide if upgrading a dependency is likely to succeed.

Use with next-update dependency upgrade checker.


Even if you have some tests, knowing if other people upgraded from version X of module A to version Y in 100% of cases brings peace of mind. Similarly, if most people had failed to upgrade automatically from X to Y, that means breaking API changes and upgrade might be harder for your project.
