5 Crucial Tips to Accelerate Angular Development and Reduce Compilation Times

Angular is an innovative JavaScript framework for building apps that can run on various platforms. However, the more your app becomes popular, the longer becomes your compilation times, which makes code writing more clumsy and reduces the productivity of your development. For the resolution of such an issue, the right solution is to hire AngularJS developers for help as you shouldn’t have to wait for the compilation to be finished to see whether or not this one line of altered code did the trick.

If you have an app of the size of a to-do app, you might not worry about the compilation times. However, in complex projects with a big development team and effectively growing third-party dependencies, the compilation times can become longer.

This article will help you understand and discuss the tried and tested tips to Accelerate Angular development and reduce compilation times with ease.

Test-Driven Development Using Jest

By default, Angular projects use the combination of Jasmine and Karma to run unit tests. For minor projects, that might be enough, but the demerits become quite apparent for complex projects. In short, Jest offers a robust CLI and a very smooth testing experience.

The test-driven development approach works well when writing JavaScript code like pure functions or some dumb components. As the unit tests must be swift for execution, you should import the essentials only and mock the rest of the things. Jest will help you in doing this with ease. For testing the Angular components, you should hire Angular developers for testing the Library to write tests that copy user behavior as neatly as possible.

Keep Up to the Present With Angular

TypeScript incremental compilation was launched in TypeScript 3.4 and has had first-class compatibility with Angular since version 8. As this is not available in the default setup, you must add the incremental flag in your tsconfig.json.

Being a default rendering engine in Angular, Ivy is helping product owners efficiently. At the same time, Bazel will help you enhance the performance once your Angular Development team feels confident enough to make them available in the default setup.

Feature Modules’ Lazy Loading

If you have placed almost everything in a single module, compile times will worsen since Angular requires restructuring much stuff.

With the help of Feature modules’ lazy loading, you can’t only enhance your application’s performance through-loading lesser JavaScript bundles, only when these are required. So, you can also shorten the compile times.

If you perform a single modification in a lazy loaded module, it should only create the affected modules and not your complete application. Separating your codebase into tiny modules means a small amount of work for the compiler.

Split Up the App Into Smaller Libraries and Apps

Even if you are performing lazy loading, you may suffer from lag in build and test times. After all, you still have an extensive app. The idea of development tools like Nx is to help you scale your development from a single team creating a single app to many groups creating multiple frontend and backend products all in the same workspace. NX can help you enforce boundaries to build libraries and apps that can be developed and tested independently.

For Example: Instead of conducting the run of the ng test to test your app when you only modified something in the login module in your app, you could complete the run for the ng test name of the Library. Like Storybook, you can also Hire AngularJS developers to build small dev apps that import only the essentials you need, like a login page, and hopefully enable faster development. Instead of conducting the run ng serve to operate the entire app, you could run the ng serve the App’s name to only run the tiny dev app.

With the Help of Storybook for Building Dumb Angular Components

The primary use of dumb components or presentational components is a good pattern in famous frameworks like React and Angular. In case you ever need to do more User- Interface related tasks, the TDD approach might not be sufficient. After all, you may not want to verify that your component is working appropriately; you also want to demonstrate how it looks visually in the browser.

Here Storybook comes into play as a crucial open-source tool for building UI components in isolation for React, Vue.js, and Angular.

The idea is that you focus on building significant dumb components in isolation. As you only want the feature ( and maybe a few dependencies), the compilation process is fast since you don’t have to create your entire app.

You can even use the Storybook and Jest combination to ensure that your YI and your components’ features are acceptable and accessible.

Wrapping Up

We hope you understand why these five tips are crucial for Accelerating Angular Development and reducing Compilation time. There are various ways to enhance your development experience time in Angular projects. This is just a glance; you can find several other beneficial tips to improve your Angular app development on the web.
