How to use the @fimbul/ymir.Format.Json function in @fimbul/ymir

export function format(value: T, fmt = Format.Yaml): string {
    value = convertToPrintable(value) || {};
    switch (fmt) {
        case Format.Json:
            return JSON.stringify(value, undefined, 2);
        case Format.Json5:
            return json5.stringify(value, undefined, 2);
        case Format.Yaml:
            return yaml.safeDump(value, {
                indent: 2,
                schema: yaml.JSON_SCHEMA,
                sortKeys: true,
            });
        default:
            return assertNever(fmt);
    }
}
