案例
HOW- 目标
- verify pkg:npm/http-errors@2.0.1
- 创建时间
- 2026-08-20T13:53:31Z
契约
- createError(status, message) creates an HttpError instance with status, statusCode, name, message, and expose (true for 4xx, false for 5xx)
- createError(status, properties) and createError(status, message, properties) attach custom properties and headers to the error
- createError(error) and createError(status, error, properties) extend existing Error instances without altering prototype inheritance
- createError[code] and createError[name] direct constructors instantiate specific HttpError subclasses with correct prototypes
- createError.HttpError abstract base class throws TypeError when directly instantiated
- createError.isHttpError(val) correctly identifies HttpError instances and duck-typed error objects while rejecting plain objects and primitives
- createError throws TypeError for unsupported argument types and falls back to status 500 for unknown status numbers
