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.
• The following modules do not fit in a serverless context, are deprecated, or are experimental, and removed from the report: _http_agent, _http_client, _http_common, _http_incoming, _http_outgoing, _http_server, _stream_duplex, _stream_passthrough, _stream_readable, _stream_transform, _stream_writable, _stream_wrap, _tls_common, _tls_wrap, child_process, constants, cluster, domain, inspector, inspector/promises, punycode, readline, readline/promises, repl, tty, v8, vm, wasi, worker_threads
• Functions that start with an underscore are internal APIs that we are not targeting at the moment.
