For $7 a month, you can get the convenience of npm without making all your internal modules public

 

When you pay for private modules, you can:

– Host as many private packages as you want

– Give read access or read-write access for those packages to any other paid user

– Install and use any packages that other paid users have given you read access to

– Collaborate on any packages that other paid users have given you write access to
