Recordsnpmws8.21.3WebSocketServer
OS × runtime at a glance
Reading a cell: The number is how many recorded observations the rate divides — one build files an observation per stage it reached, so it counts neither builds nor machines nor people. The ◆ mark says one thing only: this network ran its own contract in THIS environment and it came back clean. Whether code exists for the release and API is a separate mark and a separate fact, because a sample does not stop existing when you switch the OS filter.
- there is sample code for this release and API, whatever the environment
- we ran our own contract in this environment and it came back clean
- our sample failed here
- nothing recorded — unknown, never "works" and never "broken"
- there is a level below this cell — click to open it
Code availability is a fact about this release and this API. It does not change with OS, runtime or package manager — whether it was verified HERE is the separate mark beside it.
Published samples
- Distinguish ws package EventEmitter API and Buffer payloads from native WHATWG EventTarget WebSocket and string payloads in Node 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.

Compatibility matrix
Project-level observations and symbol/contract verifications are counted separately and never combined.
These counts do not distinguish how the symbol was called: overloads, argument shapes and options are pooled together. What a particular call shape does is proven by a sample's contract, not by these numbers.
