all-str-gen

Passwords, usernames, tokens, codes and more — all in one package.

all-str-gen provides simple generators for common application needs, with configurable options and secure random generation using Node.js built-in cryptographic randomness.

Zero runtime dependencies · TypeScript support · CommonJS + ESM

Install

npm install all-str-gen

Quick Start

CommonJS

const gen = require('all-str-gen');

console.log(gen.generatePassword());
console.log(gen.generateUsername());
console.log(gen.generatePIN());
console.log(gen.generateUUID());

ES Modules

import gen from 'all-str-gen';

console.log(gen.generatePassword());
console.log(gen.generateUsername());
console.log(gen.generatePIN());
console.log(gen.generateUUID());

Generators

| Function | Description | | ----------------------------- | ----------------------------- | | generatePassword() | Secure customizable passwords | | generateUsername() | Random usernames | | generateRecoveryCodes() | Recovery/security codes | | generatePattern() | Custom formatted strings | | generateAlphanumericToken() | Letters and numbers | | generateNumericToken() | Numeric tokens | | generateAlphabeticToken() | Alphabetic tokens | | generateToken() | Random byte-based tokens | | generatePIN() | Numeric PINs | | generatePassphrase() | Random word-based passphrases | | generateString() | Custom random strings | | generateUUID() | UUID v4 identifiers | | generateNumber() | Random numbers within a range | | generateHash() | SHA-256 hashes |

Examples

Password

gen.generatePassword({
  length: 24,
  excludeSimilar: true
});

Username

gen.generateUsername({
  prefix: 'player_',
  digits: 4
});

Recovery Codes

gen.generateRecoveryCodes({
  count: 5
});

Custom Pattern

gen.generatePattern('ORDER-{upper:3}-{digit:6}');

// Example: ORDER-KQM-048291

Token

gen.generateToken({
  type: 'alphanumeric',
  length: 32
});

Passphrase

gen.generatePassphrase(6);

TypeScript

TypeScript declarations are included:

import {
  generatePassword,
  generateUUID
} from 'all-str-gen';

const password = generatePassword({
  length: 24
});

const id = generateUUID();

Requirements

• Node.js 22 or newer
• Node.js environment (not intended for browsers)

Security

Generators use Node.js cryptographic randomness where appropriate. Random output does not guarantee global uniqueness, so applications requiring unique values should enforce uniqueness when storing them.

Do not use generated hashes for password storage. Use a dedicated password-hashing algorithm instead.
