I'm a novice with Sencha Touch and am currently developing a basic application that includes a login form and displays results in lists.
My main dilemma is about the structure of the application. Would it be best to have everything contained within a single .html file, or should I create separate pages for the login and each list? If the latter is preferred, how can I smoothly transition between views and add visual effects?
If you're looking to streamline the process of setting up your app's structure, there's a handy generator available for just that purpose. Simply navigate to the jsbuilder folder within your Sencha download, and execute a command like this:
./sencha.sh generate app MyApp path/to/myapp
This curated slide deck offers insights into the recommended structure, although further exploration may be required to fully grasp the underlying principles:
For a hands-on demonstration, check out the example app referenced in the conversation:
Starting with a single HTML file is fine, but it's important to eventually align your application structure with industry best practices for better code readability and maintainability.
With the upcoming Sencha Touch generators in version 1.1, the launch logic will be placed in an app.js file, with separate files for models, views, and controllers organized in their respective directories.
Even if you're not initially creating a full MVC application, following these conventions is recommended. Check out the Twitter and Kiva apps in the SDK (and visit ) for great examples.
While the index.html file can individually link to each file, consider using the JSBuilder tool for production to package and minify them all into one HTTP request for efficient fetching on devices.
When designing a mobile app, it's essential to consider its major functions or purposes. To ensure a seamless user experience, minimize unnecessary postbacks and loading different pages and views.
If your app serves a single purpose, it's best to keep everything on one HTML page and only divide the JavaScript files as needed for organization.
However, if your app has multiple functions (such as data entry and report generation), separating them into different HTML files may be more effective.
For instance, for a wizard-style app guiding users through various steps, keeping it all within an Ext.Panel on a single page can streamline the process by swapping out content panels as users progress.
Begin with the basics and reserve time for optimization later on. Recently, I completed a project in Sencha Touch which included various complex example files that were difficult to navigate. To simplify my learning process, I took an approach of starting with a single HTML file and gradually breaking it down into subsequent files whenever things became too cumbersome or required restructuring.
