This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. 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. Calling safe-stable-stringify.configure returns a custom stringify function tailored with the specified options.
  2. Setting circularValue to a custom string replaces circular references with that string during serialization.
  3. Setting circularValue to TypeError causes serialization to throw a TypeError when a circular reference is encountered.
  4. Setting circularValue to undefined omits circular properties from the serialized JSON output.
  5. Setting deterministic to false preserves object property insertion order instead of sorting keys alphabetically.
  6. Setting bigint to true serializes BigInt values as numbers, while bigint: false omits BigInt properties.
  7. Setting maximumDepth limits nested serialization depth, replacing deeper objects with '[Object]' and arrays with '[Array]'.
  8. Setting maximumBreadth limits the number of serialized properties per object and appends a truncation summary.
  9. Setting strict to true throws an Error when encountering non-JSON-serializable values such as functions or NaN.
