🚀 Exciting news for all Salesforce developers and admins! Introducing Salesforce Live Preview for Visual Studio Code — an in-VS Code extension that lets you preview your Lightning Web Components (LWCs) instantly as you code. Here’s why it’s a game-changer: 🔧 Code → Preview in one place No more constant browser refreshes or manual deploys. Save your LWC file and watch the preview update automatically inside VS Code. This means faster iterations and fewer context-switches. 📡 Seamless server and org integration The built-in preview server starts automatically, and you can even preview components in the context of your connected Salesforce org, complete with access to platform data via Lightning Data Service, Apex controllers, and scoped modules. ⚙️ Smart features for smoother workflow • Right-click any .js, .html, or .css file of an LWC and select “Open Lightning Component in Preview” via context menu. • Pin/unpin the preview panel so you lock in on a component you’re focused on. • Status bar integration means you control the preview server from VS Code’s UI. 📌 Getting Started — quick checklist You’ll need: • The Salesforce Extension Pack installed in VS Code. • The Salesforce CLI plus the @salesforce/plugin-lightning-dev plugin. • Then search for “Live Preview” in the Extensions view and install. 💡 Why this matters In modern Salesforce development, speed and feedback loops are key. With Live Preview, you get immediate visual feedback, enabling: • Faster prototyping of LWCs • More confident UI changes (you see results as you code) • Reduced context switch overhead (no more jumping between editor and browser) • A smoother handover between development, UI/UX review, and QA phases If you’re building Lightning Web Components or working on front-end-heavy Salesforce projects, this tool is absolutely worth adding to your toolkit. Would love to hear from anyone who’s already tried it! What’s your experience been? Any tips or edge cases you discovered?

Hello Salesforce Enthusiasts, We all know that "future methods" can only accept "primitive-type" parameters like String, Integer, Id etc. But if we find us in a situation where we need to use "future method" which should accept a custom object as parameter, which is not a primitive-type at all, what should we do? 🤔 Transforming the process into Queueable Apex would be a solution indeed but what if the code is a legacy code having a huge tech debt where you are afraid to touch more places than needed but only want to put just an "@future" before the method name? 😬 Well, there is a solution for this. 😎 You just need to transform the method parameter into a JSON String and then re-transform it back into your "custom object" type inside the method! Example: 🔵 Your original method: public static void myMethod (List<MyCustomObject> mcoList) { ... } 🔵 And how we transform it to become a future method: @future public static void myMethod (String mcoJSON) { List<MyCustomObject> mcoList = (List<MyCustomObject>) JSON.deserialize(mcoJSON, List<MyCustomObject>.class); ... } That's all. 👍 Happy coding! 🙂 #Salesforce #SalesforceDevelopers #TipOfTheDay #SalesforceApex #Apex

Hello #Salesforce Developer #Connection A developer created a Lightning web component that uses a Lightning-record-edit-force to collect information about Leads. Users complain that they only see one error message at a time when they save a Lead record. What can the developer use to perform the validations, and allow multiple error messages to be displayed simultaneously? 1.Apex REST 2.External JavaScript Library 3.Apex Trigger 4.Process Builder

💡 What I Wish I Knew Before Writing My First Apex Trigger 4 years back, I was just a developer trying to figure out what Salesforce even was. I got a task: “Write a trigger to automate this business process.” I googled, copied some code, deployed it and guess what? It worked perfectly in the sandbox. 😎 Then we moved it to production… And everything broke. 💥 That day, I realised something that changed how I build forever. Writing a trigger is easy. Designing it right is what makes you a real Salesforce Developer. Since then, I’ve written (and rewritten) enough triggers to learn these lessons the hard way 👇 🔹 Bulkification is your best friend. Salesforce doesn’t care about your one test record, it runs triggers for 200 at once. If you’re doing SOQL or DML inside a loop… you’ll meet the Governor Limits faster than you think. 🔹 Recursion is a silent killer. Your trigger updates a record → which fires the same trigger again → infinite loop 🔁 Use static variables. Or even better, a Trigger Framework. Trust me, it’ll save your weekends. 🔹 Context variables are pure gold. I used to write random if-else blocks until I learned what Trigger.isInsert, Trigger.isBefore, Trigger.newMap, and Trigger.oldMap actually mean. Once you get them, your logic just flows. 🔹 One Object = One Trigger. Multiple triggers? You’ll spend more time debugging than coding. Keep one trigger, and route logic to handler classes. It’s clean and scalable. 🔹 Patterns > Patches. The day you learn about the Trigger Handler, Unit of Work, or Domain Layer pattern. It's the day your Apex code starts feeling architected instead of hacked together. These lessons didn’t come from Trailhead. They came from failed deployments, 3 AM debugging, and the “why is this trigger firing twice?” kind of days. 😅 ⚡️Today, when I open Dev Console, I don’t just write code. I design with intent, with the why behind every line. If you’re just starting, here’s my advice: Don’t rush to make it work. Learn why it should work that way. That’s how you move from being a coder to a creator. 🙌 #SalesforceDeveloper #Apex #TriggerFramework #Trailblazer #CleanCode #SalesforceBestPractices #LearningEveryday #TechJourney #systemdesign

⚙️Custom Exceptions in Salesforce Apex: Ever wondered why experienced Salesforce Developers rarely rely on just try-catch for error handling? It’s because custom exceptions bring structure, clarity, and deeper debugging control into your codebase. Syntax: public class MyCustomException extends Exception { } What Are Custom Exceptions? ✅Custom exceptions let you define your own error types to represent specific business or system failures. ✅They go beyond generic errors, making it easier to pinpoint the real cause and handle it gracefully. For example, instead of catching a broad DmlException, you could throw a more meaningful Exception when an insert fails. That gives context — the error isn’t just “something failed,” it’s why it failed. Why Use Custom Exceptions? 1️⃣ Granular Control: You can create specific exception types for different failure scenarios, like data validation, API errors, or record insert failures. 2️⃣ Improved Debugging: Custom exceptions let you log detailed error messages, causes, and stack traces, helping you trace exactly where things broke. 3️⃣ Reusable and Scalable: Large-scale Apex applications benefit from consistent exception handling logic across multiple layers. 4️⃣ Better Readability: Instead of scattering generic catch blocks, your code communicates intent , making it easier for others to understand and maintain. 🔄 Inner Exceptions: The Hidden Power You can even chain exceptions, meaning when one error triggers another, you can pass the original one as a cause. This gives a complete error trail, showing both the original failure and where it was rethrown. Perfect for complex business logic or multi-layered integrations. When to Use Custom Exceptions? ✅ When different parts of your application need unique handling logic. ✅ When debugging production-level issues where stack traces matter. ✅ When designing frameworks or reusable service layers. 💬 Think of exceptions not as interruptions, but as signals. They tell your application something went wrong, and it’s your job to handle it in a way that’s meaningful, consistent, and user-friendly. ✨ Final Thought: Custom exceptions turn simple “try-catch” handling into a robust error management framework, one that scales with your org’s complexity. #Salesforce #Apex #DeveloperTips #ExceptionHandling #CodeQuality

⭐ Salesforce Code Builder — Cloud-Native Development Is Getting Real! Salesforce has been improving Code Builder for a while, but the latest rollout makes it way more practical — it’s now available directly inside Sandboxes. I’ve been exploring it lately, and honestly, it feels like Salesforce is moving closer to a future where developers won’t even need local setups. What Code Builder Offers 💡 A full-fledged Salesforce dev environment — right inside your browser. ✅ Pre-configured Salesforce CLI ✅ Org Browser & SOQL Builder ✅ Deploy, retrieve & test metadata ✅ Git integration (no extra setup) ✅ Apex, LWC, Aura & Visualforce support ✅ Add extensions via Open VSX Registry ✅ Built-in terminal ✅ Einstein for Developers (AI-powered code suggestions & explanations) ✅ And now… launchable directly from Sandboxes! When It Makes Sense to Use ➡️For quick fixes or lightweight enhancements — skip VS Code setup. ➡️When switching between orgs or sandboxes — open & start coding instantly. ➡️When working on shared/restricted devices — no installation needed. ➡️For collaborative teams — consistent cloud environment for everyone. ➡️To experiment with AI-assisted code generation inside Salesforce. Benefits Over VS Code & Developer Console 📌Developer Console → Code Builder No more small text boxes or limited debugging. Full project view, syntax highlighting, Git, and CLI in one place. 📌VS Code → Code Builder No local setup or CLI installation required. Preconfigured Salesforce extensions — ready in minutes. Perfect for quick org access or lightweight tasks. Integrated with Einstein for Developers for smart code assist. 💭 My Take Code Builder bridges the gap between Developer Console and VS Code — Simpler than VS Code, more powerful than Developer Console. For large-scale projects, VS Code still offers better control and performance. But for quick org explorations, testing, or light Apex and LWC edits, Code Builder is an efficient and future-ready option. Salesforce isn’t just bringing coding to the cloud — it’s bringing the entire developer experience there. #Salesforce #CodeBuilder #SalesforceDevelopers #Apex #LWC #EinsteinForDevelopers #SalesforcePlatform #SalesforceCodeBuilder
