Building a great web app development is critical for retaining happy users. But with continuous influx of bugs to fix and new features to build, it becomes easier. There are some important steps that you can take to improve your angular App’s performance substantially. Few months before, a conference discussed “How to stay fast and fresh with Angular”. The discussion was about the measures to improve angular app performance and bundle size. The suggestions from this discussion were applied through the lens of an ionic app, Ionifits. Ionifits is a Zenefits-inspired human resource demo app showcasing various Ionic app platform technologies like Ionic Framework, Ionic Native Enterprise solutions and Capacitor. These are ready to be tested in your web, iOS or android devices.

Tips To Improve Ionic Angular App Performance-

1. Divide App Into Modules For Native Angular Lazy Loading-
Ionic Angular applications has the lazy loading modules when a user navigates to their route the first time. This way is critical for the application performance for reducing the initial bundle size. Use the accompanying command to create a command for making a lazily loaded module:
$ ng generate module --module app-module --route about about
New ionic apps that were developed using the start command, are pre-arranged with lazy loading and resulting app pages, using the Ionic CLI’s generate command that subsequently designed as mazy loaded modules.

$ ionic generate page about/about

2. Keep Angular up-to-date Regularly With “ng update” –
Dependency updations consistently calls for the high risk of something breaking, which distracts from building more features for your application. Angular team is working great for Angular CLI’s update process, that updates the Angular packages when applying code transformations as needed for you. At first, run the below command to update the CLI and core-

$ ng update @angular/cli @angular/core
Then, if there aren’t any bugs, users can update angular packages. Check the angular update guide, choose the current version of app and the version that it’s being updated to. Overall updating is easy and convenient because there is very less manual work to do. The CLI looks after changes for you. Run the below command to update the Ionic dependencies of app-

Ionic Angular$ npm update @ionic/angular@latest

Capacitor$ npm update @capacitor/core@latest @capacitor/ios@latest @capacitor/android@latest

Reference the package. json files in the Ionic starter template apps to ensure whether dependencies will work together. The template apps are updated and support latest compatible versions by Ionic framework and DevRel teams.

3. Configure Size Budgets-
