Improving `Config.literal` Construction for Specific Literal Types in TypeScript

Is there a better way to construct a

Config.literal

Config.literal

Config.literal

Config.literal with a default value?

const mode = Config.withDefault(Config.literal("dev", "live")("APP_MODE"), "dev" as const);

const mode = Config.withDefault(Config.literal("dev", "live")("APP_MODE"), "dev" as const);

const mode = Config.withDefault(Config.literal("dev", "live")("APP_MODE"), "dev" as const);

const mode = Config.withDefault(Config.literal("dev", "live")("APP_MODE"), "dev" as const);

If I remove the

as const

as const

as const

as const then

mode

mode

mode

mode is of type

string

string

string

string when it should be the literal values of

"dev" | "live"

"dev" | "live"

"dev" | "live"

"dev" | "live"
