If an API fails silently without reporting errors, which guideline does this violate?

• A. G21 Fail fast; don't fail silently
• B. G24 Overload with care
• C. G11 Pay attention to edge cases
• D. G9 Avoid overly clever APIs

Answer: (A)

Failing silently without reporting errors clearly violates the guideline that encourages APIs to fail fast rather than failing silently. The primary intention of this guideline is to ensure that when an error occurs, it is reported immediately, allowing developers to identify and address the issue promptly. When an API fails silently, it obscures the root cause of the problem, complicates debugging, and can lead to further complications down the line. This practice can result in a poor developer experience as the lack of feedback may mislead users into thinking the API call was successful, thus hampering effective error handling and resolution. The other options touch upon various other design principles but do not directly pertain to the issue of error communication. For instance, guidelines about handling overload or being prudent with cleverness focus on different aspects of API design. Consequently, the guideline emphasizing that APIs should fail fast is crucial for maintaining clarity and reliability in API interactions.
