generate-short-id

A simple JavaScript package to generate short IDs with letters, numbers, and special characters.

Description

generate-short-id allows you to generate unique, random strings of any length.

• By default, it generates letters only (A-Z, a-z).
• You can optionally include numbers (0-9) and special characters (!@#$%^&*()_+-=[]{}|;:,.<>?).
• Perfect for generating IDs for fake inputs, tokens, or unique keys.

How It Works

1. You specify the length of the ID.
2. Optional boolean flags determine the character set:
   • includeNumbers → true to include numbers
   • includeSpecials → true to include special characters
3. The function generates a random string exactly matching the requested length.

Installation

npm install generate-short-id

## Usage
```bash
const { generateShortId } = require('generate-short-id');

// Letters only (default)
console.log(generateShortId(10));        // e.g., "aBcDeFgHiJ"

// Letters + numbers
console.log(generateShortId(10, true));  // e.g., "aB3dE6fHkL"

// Letters + numbers + special characters
console.log(generateShortId(10, true, true)); // e.g., "aB3$dE6!kL"

// Letters + special characters only
console.log(generateShortId(10, false, true)); // e.g., "aB@dE!fGh$"
