Salesforce Lightning Web Component Cookbook, Published by Packt
This is the code repository for Salesforce Lightning Web Component Cookbook, Published by Packt.
All of the code is organized into folders by chapter under the force-app folder. Each chapter folder contains the relevant sub folders for deployment of a project into a Salesforce org, such as classes and lwc. In order to deploy to your Salesforce org, you must have the Salesforce Extension Pack for Visual Studio Code installed, as well as the Salesforce CLI.
To access the code in the repository, fork the repository and clone your fork into your local VSCode. From there, authorize a free Salesforce Developer Org (sign up HERE), and deploy the force-app folder.
