Follow this trailhead to setup SFDX CLI (https://trailhead.salesforce.com/en/content/learn/modules/sfdx_app_dev/sfdx_app_dev_setup_dx)
Open a command prompt, such as cmd on Windows or Terminal on MacOS. Clone the Ursus Park app git repository.
git clone https://github.com/sateesh2020/bear-tracking.git
The repository contains the Ursus Park app, a Bear object with a set of fields, record and page layouts, and Apex code that retrieves bear records and sample bear records. This project base helps us focus on the Lightning Web Component development.
Navigate to the new build-apps-with-lwc directory.
cd bear-tracking
