Choosing Angular 8.0 for Mobile Application Development

The performance of an app decides users’ engagement. If an app’s performance is slow then users might switch to a competitor’s website. To improve the performance of an app, developers should carefully choose an app development framework. Our developers use the Angular 8.0 framework for web app development because it is robust and provides exceptional speed to an app. 

Released by Google in 2016, AngularJS is the most popular web app development framework used by developers across the globe. Angular 8.0 is an improved version of AngularJS. The popularity of the framework is mainly because its makers are constantly updating it with exceptional features and functionalities. 

Our AngularJS app developers use the Angular 8.0 version to provide a high-speed app that enables users to seamlessly navigate through it. Let’s find out what benefits Angular provides to the developers. 

Differential Loading of Modern JavaScript

Angular 8 makes apps more performant automatically due to differential loading. In differential loading, the CLI produces two bundles. One bundle is for modern JavaScript browsers that support (ES2015+) while the other is for legacy JavaScript browsers that support (ES₅). The browser automatically loads the correct bundle through the support from the ES6 model. Legacy and modern JavaScript bundles boost the loading speed and Time To Interactive (TTI) for a modern browser. In differential loading, new browsers will be able to load less code and smaller amounts of polyfills.  

Apart from the benefits to the developers, businesses will have a high-speed app that customers would want to visit every now and then. 

Being a SaaS mobile app development company, we ensure that whatever application we make has a high speed and it runs seamlessly across different operating systems.

Dynamic Imports for Lazy-Loaded Routes

Instead of a custom string dynamic import syntax is used by lazy-loaded routes. In case modules are missing or misspelled, TypeScript and linters can complain. 

A lazy loaded import appears like:  { path: '/cart', loadChildren:'./cart/cart.module#CartModule' }

And  when the syntax is changed it appears like this:  { path: `/cart`, loadChildren: () => import(`./cart/cart.module`).then(m => m.CartModule) }

It uses the ng upgrade command to upgrade the app. 

Improvements in the CLI Workflow: 

CLI has further improved in the latest Angular 8.0 version. The ng build, ngrun, and ng test are equipped for an extension by the third-party tools and libraries. AngularFire along with deploy command to make use of the new capabilities. 

IVY Renderer in Angular 8.0

Angular 8.0 consists of Ivy renderer and it is the reason why this framework is so popular. The Ivy addresses the issues associated with the previous renderer. The framework’s latest update includes an opt-in preview for IVY. The preview enables developers to navigate between engine build and IVY to access features included within the assignments. The latest update also modifies the dependencies if it detects any issues. Virtual DOM in the previous Angular Version is replaced with the Ivy because it is small, quick, and simple. The Ivy version addresses the performance problems of memory-constraint platforms to reduce memory allocation during rendering.  Angular 8.0 Ivy also compresses the compilation process and divides a sequence of stuff into various small segments. It has various atomic functions which is why it is optimized for TreeShaking. 

Main Concepts of IVY

1. Tree shakable: Removes unused codes to enable apps to pay attention to the codes it is using.  The unused codes accelerate run time and smaller bundles.

2. Local: Recompiles components that are changing to accelerate app compilation.

IVY reduces the bundle size of the “Hello, World” from 36KB to 2.7Kb. The page load time exceeds 93%. 

Supports TypeScript 3.4

The use of TypeScript 3.4 is mandated in the Angular 8.0 version.  TypeScript facilitates generating readable and clean JavaScript codes.

Bazel 

Apart from Ivy, Bazel is also added to the Angular 8.0 version which is the reason for its popularity. Thanks to Bazel that makes building a CLI application becomes easier. Build and used by Google, Bazel can work in almost any language input.

Benefits of the Bazel:

• Useful in frontend and backend development. 
• Facilitates in tests and incremental builds to bring profits in the rebuild times.
• Remote builts and cache gaining possibilities increase on build farms.
• Facilitates in the declaration of tasks that have a clear output or input. It also ensures that only the tasks that are necessary run.
