Salesforce Developer (Apex & LWC)

Understanding the developer's view of Salesforce.

• Salesforce as a Platform (PaaS).
• Development environments (Sandboxes) and VS Code setup.
• Declarative vs. Programmatic customization.
• Introduction to Apex and its role.

Learning the basic syntax of Apex.

• Variables and data types (Primitives, sObjects, Collections).
• Apex control flow (if/else, loops).
• Working with collections: Lists, Sets, and Maps.
• Using the Developer Console and Anonymous Apex.

Writing reusable code with classes.

• Defining Apex classes, methods, and properties.
• Constructors and static/instance members.
• Inheritance, Interfaces, and Abstract Classes.
• Understanding `this` keyword and access modifiers.

Querying data from the Salesforce database.

• Writing SOQL queries (SELECT, FROM, WHERE, ORDER BY).
• Relationship queries (Parent-to-Child, Child-to-Parent).
• Aggregate functions (COUNT(), SUM()).
• Introduction to SOSL for text-based search.

Automating logic with triggers.

• DML statements (insert, update, delete, upsert).
• Introduction to Apex Triggers.
• Trigger context variables (Trigger.new, Trigger.oldMap).
• Trigger handler pattern and best practices.

Writing testable code and handling exceptions.

• The test framework and `@isTest` annotation.
• Writing Apex test classes and methods.
• Creating test data and using `Test.startTest()` / `Test.stopTest()`.
• Exception handling with `try-catch-finally`.

Understanding the modern UI framework.

• Modern JavaScript (ES6+) basics.
• LWC vs. Aura components.
• LWC file bundle structure (HTML, JS, XML).
• Building and deploying your first LWC.

Building interactive components.

• HTML templates (conditional rendering, loops).
• JavaScript decorators (`@track`, `@api`, `@wire`).
• Handling user events (e.g., `onclick`).
• Component communication (parent-to-child, child-to-parent).

Connecting your UI to your backend logic.

• Calling Apex methods from LWC.
• Using `@wire` to read data.
• Calling Apex imperatively (e.g., on a button click).
• Displaying data and handling errors in LWC.

Deploying code and building a final project.

• Capstone Project: Build a custom LWC app with an Apex backend.
• Understanding Change Sets.
• Deploying code from a Sandbox to Production.
• PD1 exam strategies and review.
