```

This will add it to your project's dependencies. Make sure you have Node.js and npm installed in your development environment.

## Usage

`@push.rocks/smartunique` is a TypeScript-powered module designed to help you generate unique identifiers such as short IDs, UUIDs, or custom unique strings. Its primary use is in scenarios where you need to ensure the uniqueness of elements or entities within your application, such as database keys, user identifiers, or session tokens.

### Setting Up Your Project

Before diving into the examples, ensure your project is set up for TypeScript:

1. Initialize a new npm project if you haven't already:

```sh
npm init -y
```

2. Install TypeScript:

```sh
npm install typescript --save-dev
```

3. Initialize TypeScript in your project:

```sh
npx tsc --init
```

4. Ensure your `tsconfig.json` is configured to support ES Modules, as `@push.rocks/smartunique` is an ES Module package.

```json
{
  "compilerOptions": {
    "target": "es6",
    "module": "ESNext",
    "strict": true,
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true
  }
}
```

### Generating Unique Identifiers

Let's explore how to generate different types of unique identifiers using `@push.rocks/smartunique`.

#### Short Unique Identifiers

Short Ids are handy when you need a concise, highly unique identifier.

```typescript
import { shortId } from '@push.rocks/smartunique';

const myShortId = shortId();
console.log(`Generated shortId: ${myShortId}`);

// Specify a custom length for the shortId
const customLengthShortId = shortId(10);
console.log(`Generated shortId with custom length: ${customLengthShortId}`);
```

#### UUID Version 4 (Random)

UUIDs are universally unique identifiers that are widely used for ensuring uniqueness across distributed systems.

```typescript
import { uuid4 } from '@push.rocks/smartunique';

const myUuid4 = uuid4();
console.log(`Generated UUID v4: ${myUuid4}`);
```

#### UUID Version 5 (Name-Based)

UUID v5 generates a unique identifier based on a namespace identifier and a name.

```typescript
import { uuid5, uuid4 } from '@push.rocks/smartunique';

const namespaceUuid = uuid4(); // For example purposes, a random UUID serves as the namespace
const myUuid5 = uuid5('myUniqueName', namespaceUuid);
console.log(`Generated UUID v5: ${myUuid5}`);
```

#### Custom Unique Identifiers

For cases where you need a custom format for your unique identifiers, `@push.rocks/smartunique` offers `uni` and `uniSimple` functions.

```typescript
import { uni, uniSimple } from '@push.rocks/smartunique';

const customUni = uni('prefix', 16);
console.log(`Generated custom unique identifier: ${customUni}`);

const simpleUni = uniSimple('simple', 4);
console.log(`Generated simple unique identifier: ${simpleUni}`);
```

### Conclusion

Through these examples, you've seen how to generate various types of unique identifiers using `@push.rocks/smartunique`. Whether you need short IDs for concise references, UUIDs for global uniqueness, or custom unique identifiers for specific use cases, this package provides the tools necessary for your project's unique identifier needs.

Make sure to explore the package further to fully leverage its capabilities in your applications.
