In this book, you will learn how to think in Apex, how to embrace limits and bulk patterns, how to design architectures for efficient and reliable trigger handling and asynchronous operations, how to deal with different best practices depending on whether you are building software for a specific organization or for a managed package, and how to incorporate testing and diagnostic code that can improve the quality and maintainability of your Apex applications.

The book is updated for Summer 15 (API 34) and covers topics such as asynchronous design patterns, optimization techniques, event-driven programming, dynamic Apex, exception handling, security, testing frameworks, and more. You will also find examples of real-world problems and solutions that Apex developers face every day.

If you want to download a PDF version of the book, you can try searching for a torrent file online. However, we recommend that you buy the book from the official website or from Amazon to support the author and get the latest edition. You can also find the source code for the book on GitHub[^3^].

Advanced Apex Programming for Salesforce and is a must-read for anyone who wants to master the Apex language and become a better Salesforce developer. It will help you understand the concepts and principles behind Apex programming, as well as the best practices and patterns that can make your code more efficient, reliable, and scalable.

Apex Best Practices to Follow

Apex is a powerful and flexible programming language that allows you to customize and extend the functionality of Salesforce. However, with great power comes great responsibility. You need to follow some best practices to ensure that your Apex code is efficient, reliable, secure, and maintainable. Here are some of the most important ones:

  • Bulkify your code: Bulkifying your code means writing it to handle multiple records at a time, rather than one by one. This is especially important for triggers, which can process up to 200 records in a single batch. Bulkifying your code helps you avoid hitting governor limits and improve performance. For example, instead of using a SOQL query or a DML statement inside a loop, use collections such as lists or maps to store and manipulate data in bulk[^2^] [^4^].

  • Avoid hardcoding IDs: Hardcoding IDs means using literal values for record IDs, field IDs, profile IDs, or other identifiers in your code. This is a bad practice because IDs can change between different environments, such as sandbox and production, or between different orgs. Hardcoding IDs can cause errors or unexpected behavior when your code is deployed or migrated. Instead of hardcoding IDs, use dynamic references such as schema methods, custom settings, custom metadata types, or labels[^2^].

  • Use database methods while doing DML operations: Database methods are alternatives to the standard DML statements (insert, update, delete, undelete) that provide more control and flexibility over how the operations are performed. For example, you can use the database.insert method with the optional allOrNone parameter to specify whether to roll back the entire transaction or allow partial success when an error occurs. You can also use the database.saveResult class to get detailed information about the success or failure of each record in a DML operation[^2^].

  • Exception handling in Apex code: Exception handling is the process of dealing with errors or unexpected situations that may occur during the execution of your code. Exception handling helps you prevent your code from crashing or behaving unpredictably when something goes wrong. You can use try-catch-finally blocks to catch and handle different types of exceptions, such as DMLException, QueryException, LimitException, etc. You can also use custom exceptions to define your own error conditions and messages[^2^].

  • Write one trigger per object per event: A trigger is a piece of code that runs automatically when a specific event occurs on a specific object, such as insert, update, delete, etc. You should write only one trigger per object per event to avoid conflicts or duplication of logic. For example, if you have multiple triggers on the Account object for the before insert event, they may fire in an unpredictable order and cause errors or inconsistencies. To organize your trigger logic better, you can use helper classes or frameworks that separate the logic from the trigger itself[^2^].

These are just some of the best practices that you should follow when writing Apex code for Salesforce and By following these best practices, you can ensure that your code is more readable, reusable, testable, and scalable. e0e6b7cb5c
