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. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. fs-extra.readJson asynchronously reads a JSON file and parses it into an object
  2. fs-extra.readJsonSync synchronously reads a JSON file and parses it into an object
  3. fs-extra.readJson with throws: false returns null on invalid JSON instead of throwing an error
  4. fs-extra.readJson rejects with ENOENT when the specified file does not exist
