string	string	The string to validate as a URL.
options	{ lenient?: boolean; }	Validation options.
options.lenient?	boolean	If true, tries to prepend https:// to the input for lenient validation (default: false).

Returns

boolean

true if the string is a valid URL, otherwise false.

Throws

TypeError if the input is not a string.

Example

isUrl("https://example.com"); // true
isUrl("example.com", { lenient: true }); // true
isUrl("invalid url"); // false
