Salesforce is an essential customer relationship management (CRM) tool. Salesforce is more than simply a tool; it’s a gateway to optimising and enhancing your business’s operations. It has been deemed significant by several businesses due to its ability to enhance customer interactions and optimise corporate processes.
Whether you’re a tech guru or someone with no technical background, Salesforce has something to offer for everyone. With its versatile coding language and comprehensive certification programs, diving into Salesforce can open up a world of opportunities.
We will explore the main Salesforce coding language as well as other coding languages used in Salesforce in this guide, with the goal of helping you use them efficiently for your business’s requirements.
Salesforce for All: No Tech Background Required
You might believe that only tech experts use Salesforce. Even though the word “coding” might make you shudder, the truth is anyone can learn Salesforce, regardless of prior academic experience. Although obtaining Salesforce certifications can improve your employment prospects, it is not a must to begin working with Salesforce. A certification, however, can greatly advance your career by demonstrating your knowledge to prospective employers.
The Importance of Customisation and Development
Customisation is key to maximising Salesforce’s potential. Salesforce Developers play a crucial role in tailoring the platform to meet specific business requirements, enhancing functionality, and improving user experience.
Salesforce Coding Language Options
1. Apex: The Primary Coding Language in Salesforce
What is Apex?
The Salesforce programming language Apex has similarities to Java but is designed specifically for creating unique apps and platform connections.
It is a strongly typed, object-oriented Salesforce language that enables developers to execute flow and transaction control statements on the Salesforce server in conjunction with calls to the API.
Key Features of Apex
- Syntax and Structure: Apex’s syntax is similar to Java, making it easy for Java developers to learn.
- Seamless Integration: Developers can create custom applications and workflows effortlessly because Apex tightly integrates with the Salesforce database.
- Versatile Usage: Use Apex to build customisations like triggers, classes, controllers, and extensions.
- Triggers: Execute code based on specific events, such as record creation or updates.
- Classes: Define unique functionalities within Salesforce.
- Controllers: Manage interactions between user interfaces and underlying data.
- Extensions: Enhance standard Salesforce objects with custom fields, buttons, and more.
- Built-in Features: Utilise SOQL (Salesforce Object Query Language) for data retrieval, SOSL (Salesforce Object Search Language) for searching records, and DML (Data Manipulation Language) for data manipulation.
Challenges of Using Apex
- Proprietary Language: Being exclusive to Salesforce, developers who are new to the platform may need some time to get used to it.
- Governor Limits: Salesforce imposes some limits or Governor limits, on the amount of data and the number of transactions to maintain system performance. While developing complex apps, this might occasionally be challenging.
- Testing Requirements: Salesforce mandates that at least 75% of your Apex code is covered by unit tests before deployment.
- Platform-Specific: Since Apex is unique to Salesforce, it could not be directly transferable to other platforms or systems.
When and How to Use Apex
Apex is ideal for scenarios that require complex logic that cannot be handled with point-and-click tools. Best practices include:
- Using Apex triggers wisely to avoid governor limit issues.
- Writing test classes to ensure code reliability and coverage.
2. Visualforce: A Legacy Approach to Custom UIs (Transitioning to LWC)
What is Visualforce?
Developers can create unique user interfaces for Salesforce apps using the Visualforce framework. Pages can be customised to meet certain business objectives by using a set of tags and components.
Key Features of Visualforce
- Page Components and Controllers: Visualforce pages are built using standard tags and custom components. Controllers written in Apex handle the logic behind these pages.
- Customisation Capabilities: Visualforce provides extensive customisation options,
While existing Visualforce applications will continue to function, it’s recommended to consider migrating to LWC for new development projects to leverage the latest features and benefits.
3. Lightning Web Components (LWC)
Introduction to Lightning Web Components
Lightning Web Components are a modern framework for developing dynamic web applications on the Salesforce platform. They use online standards like HTML, CSS, and JavaScript to accelerate and improve the efficiency of development.
Key Features of LWC
- Modern Web Standards: LWCs use native web technologies, which enhance performance and compatibility with modern browsers.
- Performance Improvements: LWCs are designed to be lightweight, reducing load times and improving user experience.
- Examples in Action: From simple UI components to complex applications, LWCs are used to create interactive and dynamic interfaces.
Getting Started with LWC
Learn the basic syntax and structure of LWCs before anything else. Tools like the Salesforce Developer Console, Visual Studio Code, and Salesforce CLI are essential for developing and testing LWCs. Community forums and thorough documentation are excellent resources for novice users of Salesforce.
LWC offers several advantages over Visualforce, including:
- Modern Development Experience: LWC leverages modern JavaScript tooling and frameworks, providing a more familiar and efficient development experience for many developers.
- Improved Performance: LWC components are typically faster and more performant than Visualforce pages.
- Lightning Design System Integration: LWC components seamlessly integrate with the Salesforce Lightning Design System, ensuring a consistent and up-to-date user experience.
4. SOQL and SOSL: Query Languages
Introduction to SOQL and SOSL
There are two ways to query the Salesforce database: Salesforce Object Query Language (SOQL) and Salesforce Object Search Language (SOSL). SOQL is essential for querying Salesforce data. It’s similar to SQL but tailored for Salesforce’s architecture, enabling efficient data retrieval based on specific criteria. While SOSL is designed for searching text, numbers, and dates across multiple objects.
Key Features and Use Cases
- SOQL: Ideal for precise data retrieval. It supports SELECT statements with various filters and sorting options.
- SOSL: Useful for full-text searches across multiple objects. It can retrieve records based on keywords found in any field.
Advanced Query Techniques
Learn advanced querying techniques such as nested queries, relationships, and querying large data sets efficiently. Use tools like the Salesforce Workbench and SOQL Query Editor to practice and optimise your queries.
Other Coding Languages Used in Salesforce
It is possible to integrate Salesforce with other coding languages. Even though Apex and Visualforce are built into the platform, Salesforce’s powerful APIs (such as REST and SOAP) enable users to communicate with external systems that are designed in various languages. For instance:
- JavaScript: JavaScript is essential for developing Lightning components and enhancing Visualforce pages. It allows for client-side scripting, handling user interactions, and creating dynamic front-end UI elements.
- Java, Python, PHP, etc.: These languages can communicate with Salesforce via API calls to perform automation tasks, data integration, and modification. By design, Salesforce does not require Python. However, data processing, some integration tasks, and making outgoing calls using Salesforce APIs may all be done with Python in conjunction with Salesforce.
- HTML/CSS: HTML and CSS are fundamental for designing custom UIs in Salesforce. Use them to style Visualforce pages, LWCs, and custom components, ensuring they are visually appealing and user-friendly.
Because of these interfaces, Salesforce is a flexible solution that can easily interface with a wide range of third-party programs and systems.
Best Practices for Coding in Salesforce
- Tight Integration with Salesforce Database: Make sure that your code communicates directly with Salesforce objects and data for effective custom applications and workflows.
- Utilise Built-in Features: The Apex language from Salesforce has built-in functionality such as DML (Data Manipulation Language) commands for data operations and SOQL (Salesforce Object Query Language) for data retrieval.
- Test Your Code: Always test your Apex code to ensure it functions correctly. Salesforce requires that, before deployment, unit tests cover a minimum of 75% of your Apex code.
- Stay Updated with Salesforce Releases: Stay updated with Salesforce’s most recent features and deprecations to ensure your code stays efficient and functional.
Common Mistakes to Avoid in Salesforce Development
- Not Considering Governor Limits: Salesforce limits data and transactions to preserve system efficiency. Always keep these in mind when developing.
- Skipping Testing: Inadequate testing of your code can result in unexpected behaviours and mistakes when used in production.
- Not Using SOQL Efficiently: Ineffective use of SOQL can cause slow performance and reach governor limits. Always optimise your queries.
- Hardcoding IDs: Avoid hardcoding Salesforce record IDs or other dynamic values that can change between environments.
