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. semver.parse extracts major, minor, and patch numbers from a standard version string
  2. semver.parse parses prerelease components and build metadata arrays into distinct properties
  3. semver.parse normalizes version strings by stripping build metadata in format and version output
  4. semver.parse returns null when given invalid version strings in strict mode
  5. semver.parse object supports in-place version incrementing with inc
