Earlier this month at TDX Bengaluru , I had the opportunity to speak on a topic close to every Salesforce developer’s heart — optimizing the way we build on the platform. My session, titled “20 Minutes – 20 Best Practices and Tips for LWC and Apex” , was a power-packed walkthrough of essential tips that can help both beginners and experienced developers improve code quality, maintainability, and performance. In case you missed it or want to revisit the key points, here’s a quick summary of the takeaways. ⚡ Lightning Web Components (LWC) – 10 Best Practices Use Base Components Use Salesforce-provided base components whenever possible—they're optimized, tested, and customizable. Avoid Over-Modularization Modularization is good, but too much can increase complexity. Always evaluate if breaking down is truly adding value. Build Reusable Components Design your components with reusability in mind. Divide based on logical functionality. Follow Kebab-Case Naming Naming conventions matter.
