What is the optimal configuration for a private NPM repository?

I am exploring different methods for setting up a private NPM repository that integrates seamlessly with my build process. I would appreciate recommendations on how to achieve a smooth configuration, taking into consideration ease of maintenance, security, and scalability. The cost is not a limiting factor, so please share your advanced approaches or any success stories you might have. I am particularly interested in solutions that enhance performance and workflow efficiency in development environments.

try using verdaccio with custom auth setups, its easy to mantain and scale. the speed boost was noticeable compared to older methods i used. be sure to tune caching settings for optimal performnce.
