isString

isString

Verifies if provided Verificable represents a value that is a string.

The check internally is done by checking the type of the value typeof value === "string".

Possible errors:

If provided Verificable is not a string:

{
    type: "isString",
    path: [/* ... */]
}

Examples:

Each of examples uses this import statement:

const { asVerificable, isValid, isString } = require("verifica");

Null or undefined is not considered a string:

const verificable = asVerificable(null);
isValid(verificable, isString); // false

Non-string values are not matching the predicate:

const verificable = asVerificable(123);
isValid(verificable, isString); // false

String value is matching the predicate:

const verificable = asVerificable("abc");
isValid(verificable, isString); // true
