Understanding npm-link

“I used npm link while working on dependencies of the client libraries for Google Cloud Platform. All our libraries use the module @google-cloud/common. In some cases I needed to immediately see the changes in the larger libraries instead of in isolation in common.”

Mastering the two-step process of npm link is a useful addition to the toolset of any Node.js developer. The process consists of running npm linkin the dependency, and npm link some-dep in the application.”

How to Write UI components with optionally controllable state

“A large number of UI components are a function of some state and they also provide some way(s) of changing that state. A flexible implementation of these components allows both stateful and stateless usages. In React, we can maintain local state in our components via useState hook. WithuseControllableState we can maintain a local state which is optionally controlled by props.”
