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. transformSync synchronously transforms JavaScript code and returns an object with generated code string
  2. transformSync applies custom plugin visitors synchronously to modify AST identifiers
  3. transformSync generates source maps when sourceMaps option is enabled
  4. transformSync returns null when filename matches ignore pattern
  5. transformSync returns AST node when ast option is set to true
  6. transformSync minifies generated code when minified option is set to true
  7. transformSync throws a SyntaxError with BABEL_PARSE_ERROR code when given invalid JavaScript syntax
