Installation

npm install alpha-deca

Quick Start

import { randomString, randomChar, getAlphanumericChars } from 'alpha-deca';

// Generate a random 8-character string
const id = randomString(8);
console.log(id); // e.g., "A7bK9mN2"

// Generate a single random character
const char = randomChar();
console.log(char); // e.g., "X", "5", "z"

// Get all available alphanumeric characters
const chars = getAlphanumericChars();
console.log(chars); // ['0', '1', '2', ..., '9', 'A', 'B', ..., 'Z', 'a', 'b', ..., 'z']

API Reference

getAlphanumericChars()

Returns an array containing all alphanumeric characters (0-9, A-Z, a-z).

Returns: string[] - Array of alphanumeric characters

import { getAlphanumericChars } from 'alpha-deca';

const chars = getAlphanumericChars();
// Returns: ['0', '1', '2', ..., '9', 'A', 'B', ..., 'Z', 'a', 'b', ..., 'z']

randomChar()

Generates a single random alphanumeric character.

Returns: string - A single random character (0-9, A-Z, a-z)

import { randomChar } from 'alpha-deca';

const char = randomChar();
// Returns: "A", "5", "z", etc.

randomString(length)

Generates a random string of specified length using alphanumeric characters.

Parameters:

• length (number) - The length of the string to generate

Returns: string - A random string of the specified length

import { randomString } from 'alpha-deca';

// Generate different length strings
const shortId = randomString(4);    // e.g., "K9mN"
const mediumId = randomString(8);   // e.g., "A7bK9mN2"
const longId = randomString(16);    // e.g., "X5kL8mN2pQ9rS3tU"

randomNumber(length)

Generates a random string of specified length using only numeric characters (0-9).

Parameters:

• length (number) - The length of the string to generate

Returns: string - A random numeric string of the specified length

import { randomNumber } from 'alpha-deca';

const num = randomNumber(6);
// Returns: "847392"

const shortNum = randomNumber(2);
// Returns: "45"

Use Cases

Generate Unique IDs

import { randomString } from 'alpha-deca';

const userId = randomString(12);
const sessionId = randomString(16);
const orderId = randomString(8);

Create Temporary Passwords

import { randomString } from 'alpha-deca';

const tempPassword = randomString(10);
console.log(`Your temporary password is: ${tempPassword}`);

Generate API Keys

import { randomString } from 'alpha-deca';

const apiKey = randomString(32);
console.log(`API Key: ${apiKey}`);

Create Random Tokens

import { randomString } from 'alpha-deca';

const resetToken = randomString(24);
const verificationCode = randomString(6);

Generate Numeric Codes

import { randomNumber } from 'alpha-deca';

const pinCode = randomNumber(4);        // e.g., "8473"
const orderNumber = randomNumber(8);    // e.g., "56715382"
const verificationCode = randomNumber(6); // e.g., "123456"
