Cordova is used for creating hybrid mobile apps, so you need to consider this before you choose it for your project. Below are the best practices for Cordova apps development.
This is the recommended design for all Cordova apps. SPA is using client-side router and navigation loaded on the single page (usually index.html). The routing is handled via AJAX. If you have followed our tutorials, you probably noticed that almost every Cordova plugin needs to wait until the device is ready before it can be used. SPA design will improve loading speed and overall performance.
Since Cordova is used for mobile world it is natural to use touchstart and touchend events instead of click events. The click events have 300ms delay, so the clicks don’t feel native. On the other hand, touch events aren't supported on every platform. You should take this into consideration before you decide what to use.
Use storage caching as much as possible. Mobile network connections are usually bad, so you should minimize network calls inside your app. You should also handle offline status of the app, since there will be times when user's devices are offline.
Most of the time the first slow part inside your app will be scrolling lists. There are couple of ways to improve scrolling performance of the app. Our recommendation is to use native scrolling. When there are lots of items in the list, you should load them partially. Use loaders when necessary.
Images can also slow the mobile app. You should use CSS image sprites whenever possible. Try to fit the images perfectly instead of scaling it.
You should avoid shadows and gradients, since they slow the rendering time of the page.
Browser's DOM is slow, so you should try to minimize DOM manipulation and number of DOM elements.
Ensure that you test your app on as many devices and operating system versions as possible. If app works flawlessly on one device, it doesn't necessary mean that it will work on some other device or platform.
