An API should do one thing
Why: If an API can do more than one thing, it can lead to messy and error-prone code. Also, it is less readable and maintainable.
How: Don’t do different things by passing different parameter values.
Use a common parent maven project to manage the version of dependencies.
Why: Easy to update all project dependencies to the latest version. Easy to remove vulnerable dependency versions for all projects.
Use OS environment variables or external configuration files to configure all external resources like databases.
Why: Avoid exposing sensitive information.
Generated trivial files should include in the
gitignore, or put out of the project.
Why: Make sure the source code is clean and easy to commit code.
Unit test code should be able to be executed directly without preconditions like creating a database.
Why: If unit test code can’t be executed directly, test code become hard to use.
Need changed static configurations (key-values) should read from dictionary table of database or project configuration files
Why: Hardcoding makes code difficult to extend and maintain.
