0.3.4 verified Sat Apr 25 auth: no javascript deprecated

A lightweight utility library providing common regex patterns and helper functions for string validation and extraction. Version 0.3.4 is the latest stable release.

Common errors

error Cannot find module 'suf-regex' ↓

cause Package not installed or not ESM-compatible in a CommonJS project.

fix

Ensure package is installed: npm install suf-regex. For CommonJS, use dynamic import: const { isEmail } = await import('suf-regex').

error export 'default' (imported as 'sufRegex') was not found in 'suf-regex' ↓

cause Attempting default import but package only has named exports.

fix

Use named imports: import { isEmail } from 'suf-regex'.

error TypeError: isEmail is not a function ↓

cause Incorrect destructuring or using variable before assignment.

fix

Ensure correct named import: import { isEmail } from 'suf-regex'.

Warnings

deprecated Package is no longer maintained as of 2022. Consider migrating to a maintained alternative like validator.js or ow. ↓

fix Replace with validator.js: npm install validator

gotcha All functions are synchronous and perform simple regex checks; do not use for security-critical validation without additional sanitization. ↓

fix Combine with input sanitization like DOMPurify for user-supplied content.

gotcha The package does not export a default object; you must use named imports. ↓

fix Use `import { isEmail } from 'suf-regex'` instead of `import sufRegex from 'suf-regex'`.

Install

npm install suf-regex

yarn add suf-regex

pnpm add suf-regex

console.log(Patterns.email.test('invalid')); // false
