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. transformAsync asynchronously transforms JavaScript code and returns a result object containing the generated code
  2. transformAsync applies custom visitor plugins during asynchronous code transformation
  3. transformAsync generates sourcemaps when sourceMaps option is enabled
  4. transformAsync returns an AST root node when ast option is set to true
  5. transformAsync rejects with a SyntaxError when passed invalid JavaScript syntax
  6. safeTransformAsync handles errors gracefully without throwing unhandled exceptions
  7. transformAsync accepts configFile false and babelrc false to isolate execution from external configuration
