If you are from the technical world, you must know how mobile applications dominate the market. Companies understand the dominance of mobile applications, and they are finding the best ways to provide their customers with the convenience of using their products and services through mobile applications. But when it comes to developing an app, the most significant decision they have to make is to choose the right platform to build their app. 

It is a fact that native mobile applications had the edge over hybrid applications due to their immature performance and sluggish interface. All these remarks might stay true till a few years back. But things started changing for hybrid mobile apps since the arrival of the Ionic platform. The best thing is it makes mobile app monetization pretty easy.  Ionic has streamlined the hybrid development process of multi-platform applications, as it brings a classy feel to the space of hybrid applications.

Mobile app users from this digital era don't want a mobile application; they want one seamless experience that follows them wherever they are - desktop, mobile, or web. Ionic helps you deliver consistent experiences across all channels with a customizable design system and single codebase that work flawlessly. 

However, it is undoubtedly crucial to build performant applications for users with the new releases. And it is not easy with the constant influx of bugs to fix and new features to build. But it will be easy if you follow some steps to improve the performance of the Ionic app. Let's see what they are.

Different Ways to Improve Performance of Ionic App

1. Reduce App Bundle Size

Before executing in a web browser, modern web apps, including Angular apps, are converted in various ways: JavaScript files are merged, then minified, or machine-generated on occasion. The source is evaluated using source maps to rectify an application or study its bundle size. But why Source Maps? 

Examining source maps is an excellent method to figure out what happens between your code and the code delivered to the end-user. The Angular team recommends using the source-map-explorer tool to view your app's code distribution. To use Source Maps, follow the steps mentioned below:

Once you run the command, your application's code distribution will be viewed. It includes the code generated by you and the libraries currently being used. 

2. Budgets for Design Size

You should consider establishing size budgets in addition to running the source map. It is especially difficult to reduce the size of an application once it is in the middle of its production phase. As a result, configuring budget size ensures that the programme stays within the size constraints you set. It is critical to note that the suggested budgets vary for each application. It is also necessary to keep track of the correct values.

3. Modularize an application

When a user navigates to their route for the first time, Ionic Angular apps use lazy loading modules. This method is crucial for the app's performance and the initial bundle size reduction. To generate a command for constructing a lazily loaded module, use the following programme:

$ ng generate module --module app-module --route about about

Using the Ionic CLI's generate command, the new ionic apps built with the start command are pre-arranged with lazy loading and resulting application pages, which are also designed as lazy loaded modules.

$ ionic generate page about/about

4. Use Angular's native lazy loading strategy

When the user navigates for the first time, Ionic apps grab the lazy loading modules. This method is used to reduce the initial bundle size and improve the performance of the application. To construct a lazily loaded module, simply use the ng generate command.

5. Hot Module Replacement (HMR)

The Hot Module Replacement (HMR) capability is certainly a cherry on top of the CLI upgrades. The Hot Module Replacement approach allows you to make changes to your deserver without having to rebuild your app completely. This was previously only available in other frameworks, but now angular development has been given a superb HMR experience as well.

Even while HMR performs admirably in Angular, there is potential for improvement in terms of how it interacts with Ionic. This issue will be addressed in the next patch release.

To leverage HMR while developing Ionic apps, use the following command:

ionic serve -- --hmr

The Hot Module Replacement with the above patch improves the overall development experience.

Final Words

The mobile app's performance matters a lot, especially when you want to attract more and more customers to generate good revenue. However, improving the performance of an Angular app can appear to be overwhelming. Fortunately, utilizing the above method, which includes Budgets for Design Size, Reduce App Bundle Size,  Use Angular's native lazy loading strategy, and Hot Module Replacement (HMR), goes a long way by half the work for you.

These are just some instances of Ionic Angular performance optimizations that can be executed. If you want complete Ionic mobile app development, you need to search for a professional team of developers who have a high experience with Ionic. And provide you with the best Ionic app development services that meet your every business requirement.
