I've found this to be quite ergonomic and functional for handling string enumerations (including completeness in switches and record definitions): https://github.com/photostructure/fs-metadata/blob/main/src/string_enum.ts https://github.com/photostructure/fs-metadata/blob/main/src/... Usage: export const Directions = stringEnum("North", "South", "East", "West") export type Direction = StringEnumKeys<typeof Directions> (I haven't published this as a discrete npm package--IMHO you should copy and paste this sort of thing into your own tree).
