staticfromJSON(data):NodeAddress
Defined in: src/cluster/NodeAddress.ts:50
Rebuild an address from its wire form.
The declared parameter type is a promise the wire cannot keep: every caller
on the receive path hands this whatever JSON.parse produced. A port that
arrives as the string "2552" is the sharp case — toString() renders
it identically to the number, so it keys every map the same way, but
equals() compares === and never matches. A node that reads its own
address back in that shape stops recognising itself, permanently (#571).
Throwing rather than coercing is deliberate: a well-behaved peer never sends this, so there is no shape worth repairing, and the transport’s frame guard rejects malformed addresses before they get here. This is the backstop for the paths that reach it another way.
port is checked as a positive integer, not a TCP port — the same rule
ClusterOptionsValidator states and for the same reason: under
InMemoryTransport the port is a synthetic node discriminator (tests use
five-digit values), and an address is transport-agnostic. Whether a port
is dialable is TcpTransport’s business.
