A library or managed service can save substantial effort. It also introduces assumptions about compatibility, availability, and how a change will be delivered. Choosing it means accepting a relationship that continues after the first integration.
Keep a short explanation of the job each important dependency performs. Record how it is configured, where its documentation lives, and which behavior would reveal a problem. That context helps a future maintainer judge an update without starting from nothing.
Review the dependencies around a real application path. A component earns its place through the work it removes and the behavior it supports. A longer list does not make a system more capable by itself.
Bring the idea into a day.
A small application may inherit several tools through one library. Reviewing that relationship helps distinguish a required capability from a convenience that has outgrown its purpose.
Another angle on the story.
A convenient assumption should have a place to be checked. Make the expected condition visible before relying on it across many parts of an application.
- Record the purpose of an important dependency.
- Keep its configuration and documentation discoverable.
- Verify updates through a real application task.
