Function: stableMemberKey()

stableMemberKey(input): string

Defined in: packages/core/src/family.ts:173

Stable stringify: JSON with object keys sorted at every level, so two inputs that differ only in key order produce the same member key. Arrays keep their order — order is meaning there.

Throws on anything it cannot key faithfully. This function is the default derivation of an identity — the member key is embedded in the bot's instance id and is what an override is stored under — so returning a wrong-but-plausible key is the worst available outcome. Date, Map, Set and class instances all serialise to {} regardless of their contents, which silently hands back a different member's bot. Rather than collapse them, this refuses and names the escape hatch.

Accepted: strings (verbatim), plain objects and arrays of JSON scalars. Anything else — including numbers, undefined, Date, Map, Set, BigInt, functions and cyclic structures — needs an explicit options.key.

Known residual, documented rather than hidden: a string that happens to spell a JSON object ('{"a":1}') keys the same as {a: 1}. Pass options.key if a family is keyed by strings that may look like JSON.
