Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. assert getRawBody reads a readable stream and resolves to a Buffer when no encoding is specified
  2. assert getRawBody decodes stream contents to a string when encoding option is provided
  3. assert getRawBody rejects with 413 entity.too.large when stream size exceeds numeric or string limit
  4. assert getRawBody rejects with 400 request.size.invalid when stream length does not match expected length option
  5. assert getRawBody supports Node.js error-first callback convention when callback function is supplied
