What Are The Main Differences Between Ionic 3 And Ionic 4? Ionic is a world-renowned Framework that is used to design the user interface of mobile applications. Recently, the Ionic Framework team released the Ionic 4 to the Software Development Industry. This new and improved version provides changes in the project structure, performance, multiple Framework support, and new documentation. Both these versions have certain levels of similarity. However, they have significant differences in some vital regions as well. In this article, we will discuss the major differences between Ionic 3 and Ionic 4. Furthermore if you have any idea related to Ionic development and looking for experienced Ionic developer from India and USA, The NineHertz provides dedicated Ionic developers to create applications for different business models.
The Major Differences between Ionic 3 and Ionic 4 ● Change in the Name of the Packages There is a massive difference in the packet names used by Ionic 4 compared to Ionic 3. For instance, Ionic 4 uses ‘@’ to call on any package while loading the system interface. On the other hand, Ionic 3 does not use any such symbol for referring to the packages in the library. Thus, the developer can use the specific referral technology of Ionic 4 to call upon a distinct package.
● Variation in the Project Structures
The overall project layout and structure has a massive difference between Ionic 3 and Ionic 4. For instance, the developer can use a custom convention to set up the application and folder structure in Ionic 3. On the other hand, Ionic 4 uses the recommended setup of each supported framework for these purposes. Thus, if you create an Angular based application with Ionic 4, the project structure will be entirely similar to the Angular CLI application structure.
● Changes in RxJS
Ionic 4 has the latest version of RxJS, which means that all the developers will have access to version 6 of RxJS with Ionic 4. There are many significant changes that the company has introduced to this latest version. For instance, there are crucial changes in the input path of operators and core functions of RxJS. All these factors will favorably contribute to the quality upliftment of your development projects.
â—? Different Forms of Web Components
The primary goal of rebuilding Ionic 4 was to use the Web APIs. It also ensures that each component is packaged in the form of a web component. In simple terms, web components are a set of web platform APIs that allow the Ionic framework to build reusable, custom, and encapsulated HTML tags. The developers can use these tags on web pages and advanced web applications. Additionally, the developers created an opensource tool, Stencil to utilize the web components of Ionic 4. This tool also helps the developers to create fast and reusable user interface components for advanced web applications.
â—? Different Lifecycle Events The Ionic Framework development team had to remove some prominent life cycle events from Ionic 4. It means that the Ionic 3 lifecycle events like ionViewDidLoad, ionViewCanLeave, etc. are no longer available on Ionic 4. The team has added proper alternatives to these services to stabilize the Ionic 4 Framework. These new lifecycle events also allow the developer to utilize specific events such as Angular properly.
â—? Navigation Mechanism
The Framework development team has added some significant changes to the navigation mechanism of Ionic 4. For instance, Ionic 4 uses the official Angular router instead of utilizing its navController. The Angular router is the most important library in the Angular application. Thus, the developers feel a more consistent and stable routing experience throughout the application. In case the company fails to integrate these features, Ionic 4 would not maintain its navigation state on browser reloads.
The Final Verdict It is easy for the developers to migrate from Ionic 3. They can achieve this goal by simply installing the application and adding the dependencies. The Ionic Framework is an open-source tool that every developer can use for UI designs. The migration process also saves a lot of time as the developers would have to rewrite the codes developed with Ionic 3. Lastly, we can conclude that the Ionic Framework team will continue to release new versions with various additions and significant improvements.
