10 Tips About An Ext JS Tutorial For Beginners


Sencha’s ExtJS is a robust JavaScript framework for developing mobile and web applications. Thus, are you interested in using ExtJS to make amazing web and mobile user interfaces? Here are some helpful hints on Extjs tutorial for beginners that will help you to get started using Ext JS and use it to web development:

What can I do to accelerate the development speed?

Consider using Sencha Architect to construct UIs using drag-and-drop functionalities so you can focus minimum time on manual coding and speed up your development. The code generated automatically is designed for maximum performance; you may also prevent errors that occur when coding manually.

Is it a good idea to set up routing in the start itself?

You’ll need to implement routing in your app if the website uses forward and back buttons for navigation. Routing can be used to keep track of the current state of your app; however, it cannot be used to store data. Direct links can also be used to reach a particular component or page of the application. It’ll be more difficult to modify your code to enable routing later if you’re not using routing at the start. As a result, from the beginning of your project, take time to understand how routing principles function and decide, select and implement your routes.

Why is Sencha Cmd important?

Sencha Cmd is the starting point for creating Sencha applications. It’s a tool that automates the creation of Sencha Ext JS apps, from the initial design structure to the generation of deployable applications. As a result, understanding Sencha Cmd, what it does, and how to use it is critical. Before initiating development, read over the Sencha Cmd Documentation to familiarize yourself with it.

Is it possible to debug sencha apps directly?

Sencha Inspector is a debug tool for apps created utilizing Sencha frameworks. It gives you easy accessibility to classes, components, and objects. Going further, this Sencha application debugger provides application analytics and sophisticated debugging features. It also allows you to examine your app code for vulnerabilities such as component and function over nesting and the frequency of layout runs and help you enhance your application’s performance.

How can the MVC design pattern be used?

Ext JS follows the Model View Controller (MVC) architectural pattern to create the structure for the project. Even though it is not required, I propose that you organize the project’s structure better. To engage with MVC, you must understand where to put your code for your application’s user interface, login controller, and data. To construct a functional web application in Ext JS, it’s important to understand how MVC works together as well.

Where should the MVVM design pattern be used?

MVVM stands for Model–View–ViewModel, yet another design pattern to be conscious of. Despite MVC, MVVC has a view as its execution point of entry. It isolates interface development by using a markup language. The ViewModel uses the data binding mechanism to synchronize changes in-between the data model and view. Therefore, know when to utilize MVC and MVVM depending on what you’re doing.

What can be done using Schema Themer?

You may use Sencha Ext JS default themes to start designing your applications right away. You may also create custom themes to give your app the feel and look you desire. Sencha Themer, on the other hand, is the appropriate tool to utilize if you don’t want to write additional code for your own themes. It not only supports Ext JS, but it also allows you to apply styles to ExtAngular and ExtReact applications; without writing code, it saves a lot of time during development.

Is it possible to overuse the Ext.getCmp method?

You can find components by using the ‘Ext.getCmp’ method and giving the component’s ID. However, this approach has constraints. This method can be used if only one component instance is there. If there are multiple instances of the same component, this method can put you into problems. You can readily access the components when applying Object-Oriented (OO) design concepts appropriately.

Is it possible to override functions in Ext JS?

Ext.override is a method that lets you override classes and add or remove any functionality. It’s vital to remember that if you override a base class, the changes will affect all instances of that class and any subclasses that derive from it. There’s a considerable chance you’ll make a few mistakes during the process. Additionally, suppose you decide to switch to the latest versions of Ext JS. In that case, the override may no longer function as planned. There’ll be instances when overriding a class is required. When implementing the overrides in such circumstances, make sure to follow industry standards. Don’t put all of the overrides inside one file and wait for it to expand.

Why is it important to learn the difference between Classic and Modern toolkits?

“Classic” is the new label for Ext JS, which was originally recognized as Ext JS and was mainly designed for usage in desktop applications. Sencha Touch has a new name called “Modern”, and is intended for use in mobile applications. Sencha has allowed us to create “universal” applications by integrating Sencha Touch into Ext JS. Universal applications have distinct perspectives for Modern and Classic; however, these perspectives all share the same logic, which means that all the serious work can be done once. It is indeed critical to know what you’re creating before you begin so you can create the proper framework. Always come down on the side of safety and create a universal application if you’re uncertain about your roadmap.
