# Liferay Headless REST Client

> ⚠️ **Project Disclaimer**: This library is a community-maintained project and is not officially supported or maintained by Liferay, Inc. It is provided as-is with no warranty or guarantee of support from Liferay.

A TypeScript client library for interacting with Liferay's Headless REST APIs. This library provides type-safe access to various Liferay services including Commerce, Content Management, User Management, and more. It is maintained by the community to provide a better developer experience when working with Liferay's REST APIs.

## Liferay Version Compatibility

This library is designed to work with `Liferay Portal 2025 Q2` and above. The API endpoints and types are generated from Liferay's OpenAPI specifications for these versions.

## Installation

```bash
npm install liferay-headless-rest-client
# or
yarn add liferay-headless-rest-client
# or
bun add liferay-headless-rest-client
```

## Quick Start

```typescript
import { createClient } from 'liferay-headless-rest-client';
import { getProductsPage } from 'liferay-headless-rest-client/headless-commerce-admin-catalog-v1.0';

// Create a client instance
const client = createClient({
    baseUrl: 'https://your-liferay-instance.com',
    headers: {
        Authorization: `Basic ${btoa('username:password')}`,
    },
});

// Use the client to make API calls
async function main() {
    const { data } = await getProductsPage({
        client,
        query: { nestedFields: "catalog" },
    });

    for (const product of data?.items ?? []) {
        console.log(product);
    }
}
```

## Custom Client Examples

The library supports custom client implementations for different authentication methods and HTTP clients. Check out the [examples directory](https://github.com/kevenleone/liferay-headless-rest-client/tree/main/examples) for complete implementations.

#### Available Examples

1. **Ky Client** (`ky.auth.client.ts`)
   - Implements OAuth2 authentication
   - Includes retry mechanism
   - Uses the Ky HTTP client for requests

2. **Basic Authentication** (`basic.auth.client.ts`)
   - Simple Basic Auth implementation
   - Uses username/password authentication

3. **Liferay Fetch** (`liferay-fetch.auth.client.ts`)
   - Inherits fetch from Portal
   - Client-side only implementation
   - Useful for browser-based applications
