  • Mock🥸

Notes

  • All percentages in the table represent whether the shape of the API matches against the baseline.They are not a calculation of implementation compliance.
  • The percentages represent the API surface area that is matching, mocked, or mismatched.
  • The baseline column represents a union of Node.js v18, v20, and v22 API surfaces that we use as the ideal Node.js API compatibility target.
  • Mock means that the API can still be imported but it is not implemented. It will throw an error or return an dummy value if called.
  • These values have been autogenerated and may not be 100% accurate.
