Module - 3 Creating the ContactController Class

Creating ContactController Class - Salesforce Lightning

• Salesforce Lightning applications make it easy to work with data.
• In this module, you create an Apex controller that allows your Lightning application to retrieve contacts, or to Search contacts by name or by id.

What you will learn

• Create an Apex Controller that exposes data and logic to the client application

Steps:

1. Open Developer Console, by Clicking your name in the upper right corner screen.
   
2. Click on File | New | Apex Class specify ContactController as the class name and click Ok.

Implement the ContactController Class as follows :

    @AuraEnabled

    public static List findAll()

    {

        return [ SELECT Id, Name, Phone FROM Contact LIMIT 25];

    }

    @AuraEnabled

    public static List findByName(String searchKey)

    {

        String name ='%'+searchKey+'%';

        return[ SELECT Id, Name, Phone FROM Contact WHERE Name like : name Limit 25];

    }

    @AuraEnabled

    public static Contact findById(String contactId)

    {

    }

}

ContactController is a regular controller class with methods to retrieve contacts (findAll), or to search contacts by name (findByName) or by id (findById).
