Hi @briangonzalez & @sifxtreme, I have the same Curri package that's in this PR public on npmjs.com, but it's under my org. If this PR is approved I will request to transfer it to Curri npm org and I will request to be a contributor. Open to code reviews and suggestions too.

CurriClientService Documentation

The CurriClientService class enables interaction with the Curri API, facilitating operations such as fetching delivery quotes, booking deliveries, managing deliveries with multiple stops, retrieving delivery information, estimating delivery times, and canceling deliveries. This README details how to install, configure, and utilize this service in your projects.

Installation

Ensure Node.js is installed on your system. Include this library in your project using npm or yarn if lib on public registry:

Using npm

Configuration

Obtain your user ID and API key from your Curri API account. Initialize the CurriClientService with these credentials:

const { CurriClientService } = require('./dist');
const curri = new CurriClientService({ userID: "********", apiKey: "********" });
