5 Common Mistakes Developers Make with Rapid Ext JS VS Code (And How to Avoid Them)

If you code in Rapid Ext JS application development software, this blog is for you. Rapid Ext JS helps us build data rich applications through the help of Ext JS. This framework has powered enterprise apps for over a decade.

It enables low-code development with a low-code editor. It boosts speed and efficiency. That’s why it’s so popular. However, even the best tools have drawbacks.

Today, we cover five common mistakes you might make in the development process. We also explain how to fix them.

To start, many developers rely too much on the ‘drag and drop interface’ approach. It looks easy but often leads to inflexible code. Next, handling events in a complex way creates tangled logic.

You must not ignore data binding and its performance, as it can affect the performance of your apps. Poor state management leads to hidden bugs. Failing to optimize grid rendering slows down the app.

Using a lightweight GUI extension can improve performance. A code editor helps refine manual coding and reduces errors. Tracking usage data offers insights for improvement.

We break down each issue into short, digestible sections. We keep it simple and direct. Let’s begin.

Mistake 1: Over-Reliance on Drag and Drop Interface

Uh-oh! This one’s a big one.

Drag and drop is one of the best features of Rapid Ext JS. It’s available on the Visual Studio Code extension. It helps you quickly add UI components to a layout with real-time previews.

Just drag elements into place. It’s streamlined and simple. Many developers love this feature. The best part about this feature is that you get a final design preview. 

Relying entirely on drag and drop makes you “code blind.” Not literally! But it weakens your ability to write essential logic.

That’s a big risk. Using the drag and drop alone can enhance the code rigidity. It’s hard to adapt later. In the worst case, scaling and debugging turn into nightmares.

The solution? Combine manual coding with low-code tools. Drag-and-drop feature can enhance the layout creation. This happens by reducing the development time. But manually write the business logic afterward.

This approach keeps your coding skills sharp. It also makes your code flexible. 

For application development, working with remote repositories and the latest versions improves workflow. A code marketplace offers useful tools, while real-time previews help refine functionality before submitting a pull request.

Use both methods wisely. That’s how you stay efficient while mastering the fundamentals.

Mistake 2: Overcomplicating Event Handling

Any application is bound to have event handling. Event handling is a superhero when it comes to create applications faster by using Rapid Ext JS. 

Some developers write complicated inline event handlers. They tend to write too much JavaScript too fast. You can insert this code directly into your targeted component’s configuration. 

If done this way, event handling creates a mess. Debugging becomes difficult. Compatibility issues may also arise.

When something malfunctions, you could spend hours trying to find and fix the issue. That’s time wasted.

Instead, try using event delegation with a proper structure. Keep event handlers as separate functions.

By organizing your code this way, you create modular, readable code. It’s easier to understand and maintain. A well-structured editor with project-based file management and template support improves efficiency.

When you separate concerns, you make testing and debugging much simpler. Strive for clarity. You’ll thank yourself later.

I always recommend reviewing your event-handling approach regularly. Turn inline events into clear functions. This avoids unnecessary performance issues and speeds up development.

Moreover, it will enhance the readability of your code. When debugging, you’ll appreciate how well-structured your event handlers are. Explore and download better features and components to optimize performance.

Mistake 3: Neglecting Data Binding Optimization

Data binding allows Rapid Ext JS to be proactive. It can help you preview the changes inside your data.

A common mistake is manually changing data instead of using bind configurations. Some developers ignore the built-in framework tools and services.

It will allow your browser to re-render the DOM unnecessarily. That slows down the entire application. Poor handling of JavaScript can also impact the speed.

You can save time by using inline data binding features. Bind configurations automatically update the UI and efficiently manage updates.

When set up correctly, only necessary DOM elements update when data changes. This leads to a better user experience with optimized themes and preferences.

But if you keep modifying data manually, performance gaps appear. The app starts feeling sluggish, especially on Windows.

I highly recommend trying out bind configurations. It can help you accelerate the performance. .

That means less manual coding for you. Keeping a log of changes helps track optimizations.

Whenever you’re updating data, always consider performance. Rely on the features Rapid Ext JS provides to connect different components seamlessly.

Optimizing re-rendering makes your app more efficient. It also improves the overall user experience. If you need further guidance, contact support.

Mistake 4: Poor State Management

Every application requires proper state management. Without it, you’re making a big mistake.

State management is crucial in Rapid Ext JS. But some developers ignore it.

They focus only on the end product. They forget about UI manipulation. Instead, they modify the DOM directly.

While direct DOM manipulation changes the UI, it bypasses state management tools. That’s a problem.

Skipping state management creates chaos. You lose track of your application’s actual state.

When the UI becomes unpredictable, debugging is a nightmare. Tracking issues takes forever.

Solving problems in this situation is exhausting. Identifying the buggy fragment is difficult.

Instead, use state management tools. These tools keep everything organized.

They allow you to manage state in a single, structured area. That makes debugging easier.

I strongly recommend following an organized approach. Define state clearly. Modify it through structured processes.

This ensures the UI always reflects the actual state of the application. That’s how you keep everything efficient and manageable.

Mistake 5: Not Optimizing Grid Performance for Large Data Sets

Grids are widely used in Best Low Code Development Platforms like Rapid Ext JS. They allow you to visualize large data sets in a single table.

However, many developers make the mistake of loading too much data at once. They forget to implement paging, filtering, and virtualization. This often results in sluggish and unresponsive grids. In some cases, the interface may freeze completely. High memory consumption becomes a problem.

When too much data loads at once, the browser struggles. Rendering thousands of rows at once strains performance. It becomes harder to keep up. The user experience suffers. Users expect smooth performance. Long loading times and slow scrolling frustrate them.

I recommend optimizing grid performance. Use paging to load data in smaller segments. Apply filtering to display only relevant data. Use virtualization to render only visible rows. These techniques reduce the load on your browser. They also ease the strain on the interface.

A well-optimized grid feels fast and professional. It eliminates lag and creates a responsive experience.

Conclusion

By now, you should see that every feature in Rapid Ext JS has potential pitfalls. The drag-and-drop feature is convenient. However, relying on it too much makes you complacent. Combine it with manual coding to keep your skills sharp.

Event handling should be simple and structured. Inline handlers should not be used excessively. Data binding keeps UI elements in sync. It minimizes unnecessary re-renders. State must be managed efficiently. Avoid direct DOM manipulation.

A predictable application is crucial. Proper state management ensures stability. Finally, grids must be optimized. Load data efficiently to improve the user experience. All of these mistakes come from poor performance management.

Relying too much on drag and drop reduces flexibility. Complicated event handling makes debugging difficult. Inefficient data binding slows down the app. Poor state management leads to endless bugs. Slow grids frustrate users the most.

These issues can be avoided with good coding practices. Every tool has strengths and weaknesses. Rapid Ext JS is powerful, but only if used correctly. Maintain clean code. Keep your design flexible. Build strong and efficient applications. Try these methods. You’ll see the difference.
