CodeFactor Known Vulnerabilities

OpenSSF Best Practices

A run-time guard to require a value to be an integer; it will throw a ZeroDepError if the guard fails.

Full documentation is available at the zerodep.app page.

Examples

All @zerodep packages support both ESM and CJS.

import { guardInteger } from '@zerodep/guard-integer';
// or
const { guardInteger } = require('@zerodep/guard-integer');

Successful Cases

guardInteger(42); // void

Unsuccessful Cases

guardInteger([]); // throws ZeroDepError: Value is not an integer
guardInteger(['a', 'b', 'c']); // throws ZeroDepError: Value is not an integer
guardInteger(1000n); // throws ZeroDepError: Value is not an integer
guardInteger(true); // throws ZeroDepError: Value is not an integer
guardInteger(new Date()); // throws ZeroDepError: Value is not an integer
guardInteger(''); // throws ZeroDepError: Value is not an integer
guardInteger(new Error('message')); // throws ZeroDepError: Value is not an integer
guardInteger(3.14); // throws ZeroDepError: Value is not an integer
guardInteger(() => 'function'); // throws ZeroDepError: Value is not an integer
guardInteger(
  new Map([
    ['a', 1],
    ['b', 2],
  ])
); // throws ZeroDepError: Value is not an integer
guardInteger(null); // throws ZeroDepError: Value is not an integer
guardInteger({ an: 'object' }); // throws ZeroDepError: Value is not an integer
guardInteger(new Promise(() => {})); // throws ZeroDepError: Value is not an integer
guardInteger(/[regex]+/gi); // throws ZeroDepError: Value is not an integer
guardInteger(new Set([1, 2, 3])); // throws ZeroDepError: Value is not an integer
guardInteger('a string'); // throws ZeroDepError: Value is not an integer
guardInteger(Symbol()); // throws ZeroDepError: Value is not an integer
guardInteger(new Int32Array(2)); // throws ZeroDepError: Value is not an integer
guardInteger(undefined); // throws ZeroDepError: Value is not an integer

ZeroDep Advantages
