LiteralStringUnion<T>

Unofficial

A string-literal type T that still accepts any other string.

The & Record<never, never> on the string arm keeps the literal members of T visible for editor autocomplete (they are not collapsed into string), while the whole union stays assignable-compatible with string. This lets a member typed as LiteralStringUnion<T> be overridden by a subclass that returns a plain string — a bare T (e.g. 'markdown') could not, since string is not assignable to a narrower literal.

Import:

import type { LiteralStringUnion } from '@obsidian-typings/obsidian-catalyst-latest';

Example:

// Accepts `'markdown'` (with autocomplete) or any other string:
type ViewTypeName = LiteralStringUnion<'markdown'>;

Signature:

export interface LiteralStringUnion<T extends string>
