Eliminate more edge cases with less code. Automates common type checks and validation checks.
Check that value is a valid array.
Check that value is a valid array and empty.
Check that value is a BigInt type, is an integer, and is finite.
Check that value has a boolean value true or false. Does not use type coercion.
Configurable validator for string-based ID values. Accepts a number of boundary condition parameters including min/max length, allow empty, allow nulls, auto-trim, etc.
Configurable validator for URL values.
Rule validators check for a single condition using one or more function arguments and return a strict boolean value true or false.
Determine if value is a power of exponent.
Use cases
- User uploaded image dimensions.
- Texture sizes with size requirements, e.g. the power of 2 rule.
- Cases where inputs may have non-number or non-finite values.
- Performs type and bound checks on values before attempting to use math functions and returns
falseif the call would otherwise fail.
// Determine if 0 is a power of 1.
const result = powOf(0, 1);// Determine if 100 is a power of 10.
const result = powOf(100, 10);
Determine if value is an array and if so, whether it's empty. Does not throw. Returns false in all cases where value is not an array.
const value: string[] = ['one'];
// Result is FALSE.
const result = isArrayEmpty(value);// Result is FALSE.
const result = isArrayEmpty(null);// Result is FALSE.
const result = isArrayEmpty({});const value: unknown = '081408';
const result = Array.isArray(value) && value.length === 0;
