Type Alias NonEmptyString

Branded string type for non-empty strings (strings with at least one character).

Defined as an alias of MinLengthString<1>, so it participates in the length-constraint subtyping relation: a NonEmptyString is assignable to MinLengthString<0>, and any MinLengthString<N> with N >= 1 (or FixedLengthString<N> with N >= 1) is assignable to NonEmptyString.

Example

const isNonEmptyString = (s: string): s is NonEmptyString => s.length > 0;

const greeting = 'hello' as NonEmptyString;

const atLeastOne: MinLengthString<0> = greeting; // OK
