Key insights

💡Generate unique identifiers outside the database to avoid conflicts in a distributed environment.

🔑Use meaningful identifiers that provide information about the entity being identified.

🔁Include available actions in the response to guide client behavior and reduce duplication of logic.

Don't handcuff yourself in the response by allowing room for future changes that are backward-compatible.

💬Use the language of the domain in your API to improve clarity and understanding.

Q&A

Why is generating unique identifiers outside the database important?

In a distributed environment, generating identifiers in the database can lead to conflicts. By generating them outside the database, you can ensure uniqueness and avoid issues.

What are the benefits of using meaningful identifiers?

Meaningful identifiers provide information about the entity being identified, making it easier for developers to understand and work with the data.

Why should available actions be included in the response?

Including available actions in the response helps guide client behavior and reduces the need for duplicated logic on the client side.

What does it mean to not handcuff yourself in the response?

Not handcuffing yourself in the response means allowing room for future changes that are backward-compatible, minimizing the need for breaking changes.

Why is using domain language important in an API?

Using domain language improves clarity and understanding, as it aligns the API with the terminology and behaviors of the domain.
