What Is Angular?
In a changing world of front-end JS frameworks, Angular, after being released by Google in 2010, quickly established its position in the market. As a TypeScript based JS framework, Angular has a very well-developed structure which provides easy two-way data binding. It also comes in an MVC model (Model View Controller), thanks to which it can split the tasks into a logical sequence, thereby reducing the time to load the webpage.
Additionally, it has also had a built-in module system and routing package. The MVC model part if it allows for a separation of concerns–meaning that the client has the viewing option which dramatically reduces any queries that might arise in the background.
The general pros of this would most definitely include the two-way data binding option as it gives the developer, changes made to the model instantaneously into the views in an effortless and intuitive way. It is also a popular JS framework in the field with various professionals swearing by it.
On the downside, it is a heavier application which takes more time to load due to the multiple features available. This might amount to slower delivery time on important projects and thus greater burden. Additionally, there are many updates that are made which might be slightly time-consuming and difficult to learn and adapt. Angular v7 was last launched in October of 2018.
What is React?
With an initial release by Facebook back in 2013, React is a front-end library used to create important and reusable UI components which aid in building large-scale web apps that can change data without having to reload the page. This JS framework is being used by Instagram and Whatsapp as well.
It works on being fast and simple at the same time. It does not incorporate the MVC template in its structure as it works primarily as a front-end library. However, one can consider it in the view part of it.
One of the main selling points of the framework is the fact that its performance is top-notch. Boasting of a gzipped file having a size of 43KB, React is gaining popularity for its speed and the many features it promises. Like using a virtual Document Object Model (DOM). Since the directives can track and monitor the behavior of each component, React promises optimal efficiency as it re-renders the nodes whenever needed.
Another impressive feature is minimizing the resource load on the end-user through systematic support for bundling and tree-shaking. React also supports server-side rendering for any projects which need that kind of rendering.
Looking at the pros, one can definitely point out the benefits of a virtual DOM over others as it extensively reduces the workload on the apps. The one-way data binding process gives greater control over the flow of the full project as the data is unidirectional.
There are a few downsides to React. Firstly, the documentation levels are not the greatest. With the absence of an MVC model, one often finds themselves in need of extra libraries to implement the state and the model. Add to that the constant updates in both these libraries, React oftentimes seems to be accelerating too fast to write the instructions properly. These changes put the burden on the developers to constantly update.
What is Vue?
Vue.js, as it is known, is one of the newer frameworks introduced into the world of Java. Developed by Google’s ex-employee, Evan You in 2014, Vue is known for its progressive approach to building user interfaces. When seen in comparison to Angular and React, Vue does not follow the same cornerstones and is viewed as extremely user-friendly.
It is relatively easy to learn and has the ability to create efficient, fast and very intricate single-page applications. Vue utilizes the same virtual DOM as React and can make use of both reactive and composable view components. This framework focuses on the efforts made toward the core part of the library which allows it to re-route other important functions to companion libraries.
The current version at 2.17 which was released on August 2018 is incredibly fast. Despite being 18KB after gzipping, its overall performance is impressive. It can incrementally adopt parts of its technology without being too difficult to learn for newcomers as well as old-time professionals. The effort put in for the documentation is also worth mentioning while the easy integration into projects makes for additional points.
On the flip side, Vue is a relatively new framework that is yet to be adopted commercially in comparison to the popularity of Angular and React. As a result of which there is an immediate need to grow the community of users before there is a spike in the market.
Comparing the 3 frameworks based on ease of learning, size and load time, efficiency in migration, here are the differences that could be noticed.
a) Ease of learning.
Angular- The more advanced version of Angular requires the professional to learn additional modules like TypeScript and MVC. However, once the person understands the concepts, they would be well-versed in front-end work completely.
React- This is not a complete framework and hence might utilize the knowledge of third-party libraries. This can make the learning procedures of React quite easy in comparison. The solutions to the many problems one might face are also available on the internet like StackOverflow which makes it even simpler for users.
Vue– This is the easiest to learn as it has the opportunity for higher customizability. Additionally, it has the overlap option with the other two frameworks making the transition an easy step.
In comparison to the average web page size that is around 2MB and above, these differences in file size are not very significant.
The load time for Vue is the fastest when compared to Angular and React. This can be attributed to the smaller size. Angular, due to its heavier structure is the slowest in this department.
c) Ease of migration
At any point in time, if there is an update, there is no need disturbance in the code. Even though it is not necessary to migrate to a newer version, it would be imperative to keep track as these updates can often be significant.
Angular- It takes around 6 months for any update from Angular. It takes another six to release any major APIs. So annually, there is a bi-yearly cycle in case one needs to make the necessary changes.
React- The upgrade through the versions is relatively more relaxed. There are scripts like react code mod that helps you navigate.
Vue- If one is migrating from 1x to 2, then 90% of the APIs are the same as promised by Vue. Additionally, there is a migration helper tool that helps one navigate through the changes.
Why should one go for Angular?
One of the main reasons to go for Angular is for applications that are dynamic and need the display content to be changed accordingly based on user behavior. What Angular does is ensure that once the component is changed, all the aligned components are updated as well.
It is still a great framework for larger applications. It has exceptional support when it comes to working with TypeScript. The Model-View-View-Model (MVVM) allows developers to separate their work on the same app section using the same set of data.
Cons of Angular:
Harder to learn and heavier as a file which delays performance when compared to the other two.
Why should one go for React?
As mentioned before, React is performance-based. Using a virtual DOM ensures there is speed without sacrificing the performance. It also uses JSX for templating and boasts of a high level of documentation. It is meant for applications that require versatility as there are features like React Native for mobile development among others.
It provides better SEO when seen with Google as a metric There are greater optimizations for rendering and the one-way data binding procedure reduces unwanted side effects.
Cons of React:
As it moves away from the class-based components, those well-versed in Object-Oriented Programming are finding the transition difficult.
Why should one go for Vue?
Speed is an important factor at Vue and is one of the frameworks that can be used to speed any project. The application is light which enables it to perform faster and in a more limited environment, unlike the others. Hence the overall user experience is great.
Due to the in-built structure of Vue, one can integrate a framework into an existing app without having to worry about performance. It saves time and money–two factors that make it extremely popular among startups and smaller organizations.
Vue is also the easiest to learn as a framework and incorporates reusable components that can be made is limited time.
Cons of Vue:
This one is still has a smaller market share and might not be able to perform in the same capacity for heavier projects.
We have charted out the various advantages as well as disadvantages of the three JS frameworks. Which one would be best suitable for the project at hand depends on what is needed in the first place.
