Type Alias: Override<T, M>

Override<T, M> = { [K in keyof T]: K extends keyof M ? undefined extends T[K] ? M[K] | undefined : M[K] : T[K] }

Defined in: js-server-sdk/src/types.ts:27

Replaces the types of fields in T whose names appear in M, leaving the rest untouched. Produces a flat object type (single mapped type, no Omit & {...} chain) so editor hover displays the resulting properties directly.

Keys present in M but not in T are ignored — only fields that already exist on T are overridden, so a shared override map can be reused across multiple source types.

undefined is re-added to the override when the original field allowed it, so optional fields on generated proto types (e.g. peerId?: string | undefined) remain assignable from undefined under exactOptionalPropertyTypes.
