Type Alias: CmcdCustomKey
ts
type CmcdCustomKey = Lowercase<`${string}-${string}`>;Defined in: CmcdCustomKey.ts:17
A custom key for CMCD. Custom keys MUST have a hyphenated prefix to ensure that there will not be a namespace collision with future revisions to this specification. Clients SHOULD use a reverse-DNS syntax when defining their own prefix.
The type requires a lowercase hyphenated string. At runtime a key must also satisfy isCmcdCustomKey: a lowercase first letter, then characters from a-z 0-9 . -. The key needs a hyphen that is neither first nor last. The check restricts the CMCD custom-key grammar to names that RFC 8941 key serialization accepts. Preparation drops keys that fail the check. Lowercase reverse-DNS names satisfy all constraints.
