nonEmptyString

function nonEmptyString(value: unknown, name: string = "value"): string;

The older form of requireNonEmptyString, kept for the code that already calls it. Its second argument is the name to put in the message rather than the message itself, which is the opposite of every other guard here — that is why it was replaced.

Parameters

Parameter	Type	Description
`value`	`unknown`	The value to validate.
`name` (optional) `= "value"`	`string`	The argument name to put in the message. `"value"` by default.

Returns

string — the same string.

Throws

Exception	Condition
`InvalidStringException`	the value is not a string, or holds nothing but whitespace.

Examples

In use

nonEmptyString("Data", "sheetName"); // => "Data"
