As a developer, if you want to level up your career in Salesforce development, you should focus on getting more experience with the Lightning Web Components. LWC is one of the strongest pillars of modern Salesforce development that offers a framework for building an efficient and dynamic user interface.
As developers continue to adopt LWC, you must arm yourself with the right development tools which will help make sure the development process becomes smoother. These toolkits also help to maintain code quality and increase productivity. So, in this blog, we are going to introduce some of the most popular development tools for LWC and best practices for using these tools.
What is LWC?
Salesforce has developed an innovative programming model, Lightning Web Component(LWC). It is used to create strong and responsive single-page UI applications for mobile and desktop. The new model coexists with the Aura Components model and provides unsurpassed performance. The UI framework is designed using native HTML and contemporary JavaScript.
It adheres to key web component standards while incorporating bespoke features such as templates, modules, shadow DOM, and other new ECMAScript7 language structures. Furthermore, LWC development is easier than AURA development because developers who know HTML and JavaScript can code with greater ease, as Lightning Web Components are built on standard web technologies.
Essential Development Tools for LWC
To work efficiently with LWC, you’ll need tools for writing, testing, and debugging your code. Here are some of the fundamental tools that any LWC developer should be familiar with.
1 Salesforce CLI (Command Line Interface)
Salesforce CLI is a powerful command-line tool that simplifies the management of Salesforce DX projects. It’s essential for creating and managing LWC projects, running tests, deploying components, and handling various tasks in Salesforce development.
Key Features:
- Project Management: Create and easily manage Salesforce DX projects and LWC components.
- Testing and Deployment: Run tests, deploy source code, and manage environments directly from the command line.
- Automation: Automate repetitive tasks to streamline your development workflow.
Example Commands:
- sf lightning:component:create: Creates a new Lightning web component.
- sf project:deploy:source: Deploys source code to the Salesforce org.
2. VS Code and Salesforce Extensions
Visual Studio Code (VS Code) is a widely used integrated development environment (IDE) that becomes a powerful tool for LWC development when paired with Salesforce-specific extensions. These extensions provide features like code editing, syntax highlighting, autocomplete, and integration with Salesforce CLI.
Key Features:
- Code Editing: Write and edit your LWC code efficiently with support for syntax highlighting and intelligent code completion.
- Debugging: Debug your LWC components directly in VS Code with integrated tools.
- Salesforce CLI Integration: Seamlessly run Salesforce CLI commands from within the editor.
Recommended Extensions:
- Salesforce Extension Pack: A must-have for Salesforce developers, offering tools for development, debugging, and deployment.
- Prettier: Ensures consistent code formatting across your projects.
- ESLint: Helps enforce coding standards and catch potential issues early.
3. LWC Recipes
LWC Recipes is a collection of code examples that demonstrate common LWC scenarios. These ready-to-use examples provide a valuable resource for learning best practices and patterns in LWC development.
Key Features:
- Learning by Example: Understand how to implement various features in LWC by studying practical examples.
- Best Practices: Learn and apply best practices in your projects to ensure high-quality, maintainable code.
- Quick Reference: Use these recipes as a quick reference when implementing similar features in your projects.
Usage: LWC Recipes can be accessed through the Salesforce GitHub repository, where you can explore, clone, and experiment with the examples provided.
4. Chrome Developer Tools for LWC
Chrome Developer Tools are built-in browser tools that allow you to debug and profile LWC components. These tools are essential for inspecting components, monitoring performance, and identifying issues in your LWC applications.
Key Features:
- Inspecting Components: Analyze the DOM structure and properties of your LWC components.
- Performance Monitoring: Identify performance bottlenecks and optimize your application.
- Debugging: Use the Console and Network tabs to debug issues and monitor API requests.
Usage Tips:
- Elements Tab: Inspect the structure and properties of your LWC components in real time.
- Console Tab: Debug JavaScript errors and log messages directly from your components.
- Network Tab: Monitor API calls and data transfer to ensure efficient communication with Salesforce.
5. Local Development Server
The Local Development Server allows you to run and test your LWC components locally without deploying them to Salesforce. This tool speeds up the development process by enabling rapid testing and iteration.
Key Features:
- Rapid Development: Test your LWC components locally, making quick adjustments without needing deployment.
- Immediate Feedback: Get instant feedback on your changes, allowing for faster debugging and refinement.
Example Commands:
- sf lightning:local:start: Starts the local development server for LWC.
6. Jest for LWC
Jest is a testing framework used for unit testing LWC components. It allows you to write and run tests to ensure your components work as expected and helps you maintain high code quality.
Key Features:
- Unit Testing: Write unit tests for individual LWC components to ensure they function correctly.
- Mocking: Mock dependencies and external services to isolate your tests.
- Snapshot Testing: Capture snapshots of your component’s output to detect unintended changes.
Pro Tip: Write and run test cases with Jest, then review test coverage reports to identify areas that need more thorough testing.

7. Apex Replay Debugger
The Apex Replay Debugger is a tool for debugging Apex code, which can be particularly useful when integrated with LWC development. It allows you to replay debugging sessions, inspect variable states, and set breakpoints to analyze code behaviour.
Key Features:
- Replay Debugging: Rewind and step through your Apex code to identify issues.
- Inspecting Variables: View the state of variables at different points in your code.
- Setting Breakpoints: Pause execution at specific lines to investigate issues.
Integration: Apex Replay Debugger integrates seamlessly with VS Code, allowing you to debug Apex code in the same environment where you develop LWC components.
8. Salesforce Lightning Inspector
Salesforce Lightning Inspector is a Chrome extension that helps you inspect Lightning components, including LWC. It provides insights into component hierarchies, performance metrics, and event propagation.
Key Features:
- Inspecting Component Hierarchy: Visualize the structure of your LWC components.
- Performance Metrics: Monitor the performance of your components to ensure optimal load times.
- Event Propagation: Track events within your components to understand how they interact.
Usage: Use Salesforce Lightning Inspector to debug and optimize your LWC components by gaining deeper insights into their behaviour within the Salesforce platform.
Winding Up
LWC makes it easier to build applications on the Salesforce platform, but using the right development tools is key to success. Tools like VS Code for editing and Salesforce CLI for managing projects each serve a specific purpose. These tools help you write better code, boost productivity, and streamline your workflow, making your development process smoother and more efficient.
