Installation

npm install liferay-headless-rest-client
# or
yarn add liferay-headless-rest-client

Quick Start

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);
    }
}
