How Ivy Works?

For Angular's newest version for compilation and rendering pipeline, Ivy is the code name. Angular version 9 releases the new compiler and runtime pedagogy implemented by default rather than the older compiler and runtime, View Engine.

The existing rendering engine, Ivy, is used everywhere and has been improved and optimized in recent times. Overall, it authorizes the modernization of the Angular Package Format (APF), minor use of the compatibility compiler ngcc, and simplification of the component API. Hire mobile app developers to utilize the latest version and incorporate components of Ivy.

Ivy is an entire rewrite of Angular's rendering engine, which is the fourth and third since Angular 2. But unlike rewrites two and three, Ivy promises huge improvements to your application. With Ivy, you can compile components more independently of each other.

It will improve development times since recompiling an application will only involve compiling the changed components.

Main highlights of Angular Ivy

Angular Ivy modifies how things work internally without changing the applications.

The most advanced renderer comes with the following features:

Smaller bundle size
Faster compilations
Better debugging
Incremental DOM
Enhanced Template Type Checking
Optional Ivy Features

Why use Ivy?

A lot of us forget that HTML will never touch the browser. HTML will be compiled by Angular into JavaScript instructions to develop the right DOM when the component appears on the page. It will then update the component when the state changes. So, the huge part of Angular is its compiler which takes all your HTML and makes the necessary JS code.

This compiler and the runtime have been entirely rewritten over the last year, and this is all about Ivy. Angular is a great framework that gains the same that is done by HTML with Ivy as a complete rewrite of the compiler to:

Reach better build times.
Reach better build sizes.
Unlock new potential features such as metaprogramming or higher-order components, a recent change detection system not based on zone.js, and more.

Now the "Why" for IVY has 2 main answers:

For Locality

Locality here means a principle that Ivy follows. The idea behind this principle is to compile one file at a time.

And it was here, emphasizing "only one" because only one means just one component file and its template and no other dependencies, which will make the compilation process much faster and simpler. Earlier, it was impossible to balance code to ship to the AoT compiler, but now it will create a balance between AoT and JiT.

For Tree shaking

The Tree Shaking technique of Ivy is used to create optimization that assures that the ineffective code is not included in the final bundle during the application's build process. Therefore, developers don't have to send the whole framework code. It can be done with the functionalities used in app development. The main benefit of Tree shaking for optimization is reducing startup time.

Upgrading to Angular 9 with Ivy

Upgrading to Ivy for version Angular 9

To begin with, establish Angular CLI v9. In your terminal, run the command below.

npm install -g @angular/cli@9.0.1

Relying on your system, developers may have to run this command operating sudo.

Before elevating the app to Angular 9, you must boost it to the advanced Angular 8 version. To do this, open the terminal in the base directory of the Tic-Tac-Toe app and run the update command as follows.

ng update @angular/core@8 @angular/cli@8

Before restarting, you will have to install any altered package dependencies and commit the modifications to git.

Run the following two commands.

npm installgit commit -a -m "Advance to the latest version of Angular 8"

Now you can revise to Angular 9 by running ng update again with different arguments.

ng update @angular/core @angular/cli --next

This can take a few minutes to finish. Then you are required to install any modified package dependencies again and save and commit all to git.

npm installgit commit -a -m "Upgrade to Angular 9"

Now, boost the Angular Material libraries to their latest version.

ng update @angular/material --next

You might receive an error about Angular Flex-Layout:

Package "@angular/flex-layout" has an incompatible peer dependency to "@angular/cdk" (requires "^8.0.0-rc.0", would install "9.0.0"). Inconsistent peer dependencies were discovered.

Add --a force to the above code to work around this.

ng update @angular/material --next --force

Update Angular Flex-Layout to the updated version:

npm i @angular/flex-layout@9.0.0-beta.29

Features of IVY in Angular 18

Lazy-loaded components

entryComponents commands are depreciated as they are no longer needed. Any Ivy feature can be lazy-loaded, and it can be dynamically rendered. It shows without routing or Angular modules, developers can now easily load and render a component.

Yet, mobile app development companies have to use component render modules to link a component’s template to its declarable dependencies in practice. Here, the libraries only used by a lazy-loaded component are wrapped in lazy-loaded chunks.

Globalization

For globalization, locales consist of data formatting, number formatting, and similar regional settings that can be dynamically loaded at runtime. It directly loads to runtime and is not registered at compile time.

Better Debudding and Error Handling

With Angular 18, Ivy provides even more detailed and helpful error messages, making it easier for developers to diagnose and fix issues. Enhanced stack traces and error reporting improves the overall debugging experience.

AOT Compilation Everywhere

For the development server and even tests, AOT is now allowed by default. Initially, AOT compilation was considerably slower compared to JIT compilation, so JIT was specially utilized for the development and testing of the app.

Using Angular Ivy's build and reconstruction time progress, AOT compilation has a great developer experience at present.

When JIT compilation was utilized in phases and only AOT compilation in the final build, bugs were caught when doing production builds or at runtime. With an angular mobile app development company, you can add AOT Compilation along with other features of Ivy to incorporate into your application.

Backward Compatibility

Ivy in Angular 18 is designed to be fully backward compatible with previous versions of Angular. This allows developers to upgrade their applications without major refactoring, ensuring a smooth transition to the latest version.

Faster and More Accurate Hot Module Replacement (HMR)

With Ivy, Angular 18 improves the Hot Module Replacement feature, allowing developers to see changes in real-time without refreshing the entire application. This speeds up the development process and provides a smoother development experience.

Better Support for Advanced Animations

Ivy in Angular 18 offers enhanced support for complex animations, making it easier to create rich, interactive user experiences. This includes more flexible animation triggers and better performance for animations.

Bundle Sizes

Ivy can help smaller bundles due to its implementation of the Ivy Instruction Set, tree-shakable runtime rendering instructions. This is great for use cases in Angular elements, micro frontends, and web apps where Angular itself does not hold the entire document.

Regardless of the difference in the bundle sizes between View Engine and Ivy, bundle sizes vary based on the size of the application and the 3rd party library used by the web app development company.

In general terms:

Small and specific applications will see a considerable bundle size decrease.
Complex applications will expand the main bundle but drop-loaded bundle sizes.

It represents a large combined bundle size is reduced for great applications, which could mean an overall increase in size for medium-sized applications. The primary bundle's size will likely grow in both cases, which is not good for the initial page load time.

Concluding: Future of Angular with Ivy

Ivy marks a significant turn in the direction of a more effective, adaptable, and developer-friendly framework for Angular as it continues to mature. Ivy has the performance improvements, bundle size optimization, and debugging tools necessary to propel Angular development forward. Ivy makes it easier for developers to design complex, high-performance applications by offering strong support for dynamic components, enhanced internationalization, and shorter build times. By embracing these developments, Angular strengthens its position as a top framework in the web development industry and opens the door for even greater efficiency and creativity in the years to come.

Ivy is an essential stone in Angular history that changes how the framework internally works without changing Angular web app development. In addition to that, it forms the ground for Angular Elements to evolve general in our Angular applications.
