What Does Vue 3.0 Mean for Web Development?

Last November, Vue creator, Evan You, showcased the key updates on Vue 3.0 — the latest iteration of the rising Javascript framework. These optimizations make Vue more efficient, modular, and easy to use. I will discuss these changes and the impact I believe they’ll have following Vue 3.0’s release.

What is Vue Right Now?

In their own words, Vue is a “progressive framework for building user applications”. It’s designed to be super flexible with the ability to either incorporate individual Vue libraries into other projects or powering complex projects entirely with Vue.

Vue is often seen as one of the more approachable and easy-to-implement frameworks. Allowing support for pure HTML templates whereas tools like React define DOM elements using Javascript.

As of early 2019, we are still in Vue 2.0. While still holding a tiny share of the market in comparison to React and Angular, Vue has been continuously rising in popularity. In my opinion, the release of Vue 3.0 will boost its usage and make it even more of a legitimate alternative to the other major frameworks.

Below is a graph showing the number of job availabilities for each framework. As you can see, VueJS still as a ways to go before coming close to the current industry standards.

The Biggest Changes in Vue 3.0

In his keynote, Evan You highlighted five key changes coming in Vue 3.0:

  1. Speed
  2. Size
  3. Maintainability
  4. Targeting Native
  5. Ease of Use

Now let’s explore these in depth.

Making Fast Faster

This topic took up a large portion of You’s talk as it has the most technical changes and is clearly one of Vue’s major selling points nowadays.

VueJS is already known for its render speed. In it’s comparison tests, it outperforms other frameworks. However, the number of edge cases and fixes made to the 2.0 code made the Vue team decide to completely rewrite the rendering code using micro-optimizations. According to You, these optimizations can create up to a 100% increase in mounting and initialization speed.

VueJS, like other frameworks, uses a virtual DOM to render its components. In order to speed up the rendering process, the workload of this virtual DOM has to be reduced. 3.0 includes the following features to meet this goal:

Compile Time Hints — by overhauling the rendering process, Vue 3.0 will output better compile time hints that show code optimizations

Component Fast Path — instead of checking if a template object is a component, Vue 3.0 will make the assumption that capitalization marks a component. This assumption takes out the guesswork and speeds up the render process.

**Monomorphic Calls **— anyone who has taken a computer science class has had the concept of polymorphism hammered into their brains, but Vue 3.0 uses monomorphic calls in its rendering process. This micro-optimization always passes objects of the same shape to the render engine which makes it easier Javascript engines to optimize.

**Optimized Slots Generation **— this seemingly complex term actually boils down to a simple concept: making sure dependencies are tracked by the instances that use them. Currently, whenever either a parent and child component has an updated dependency, both are forced to re-render. However, in 3.0, the parent and child would have different dependencies and will only update when their respective dependencies change. This drastically reduces the number of re-renders that occur on a page.

Static Tree Hoisting — while this is not new (it exists in Vue 2.0), static tree hoisting greatly improves project speeds. As the name suggests, does not re-render static elements that do not have any dependencies. This greatly reduces the work of the virtual DOM and saves a lot of project overhead.

Proxy Based Observations — Vue 3.0 will use ES2015 proxy-based observations in order to track element’s reactivity. Not only does this change eliminate the several cases that Vue 2.0 was not able to support, but it also performs a lot better. According to You, these optimizations can lead to 100% faster component instance initialization and, in comparison to 2.0,

Proxy Based Observations over double the speed, and half the memory usage than the Vue 2.0 observers.

Even More Lightweight

Currently, VueJS is already small (20 kb gzipped). However, thanks to tree shaking (eliminating non-vital code), the estimated size for 3.0 is roughly 10 kb gzipped. This is by removing all libraries that are non-essential for a Vue project and having them available through import statements instead of packed in the main src.

Increasing Maintainability

**Flow to TypeScript **— to make it more accessible for more users, Vue 3.0 will transition from Flow to TypeScript. While the codebase will be rewritten to use Typescript, You made it clear that there was a heavy emphasis on making it compatible and easy to work with for people who don’t like using Typescript and would rather use pure Javascript.

**Decoupling Packages — **in comparison to its current state, Vue 3.0 is a much more modular experience that relies on its own internal packages in order to run. This makes it customizable and flexible while also giving it transparency that will allow developers to really get into the source code.

Compiler Rewrite — this is one of the features that I’m most excited for. Not only do these changes allow for better IDE support, but now it creates source maps meaning that when there is a runtime error, it will give file location and line numbers of the error. If you work with Vue now, you know that a runtime error message is very little help in identifying the problem. This update should be a breath of fresh air developers.

Making it Easier to Target Native

Vue 3.0 will be platform agnostic — meaning that it will run pure Javascript and will not assume web features such as Node.js on its main build. This makes it easy to build applications for web, iOS, or Android because of the flexibility. By targeting native, Vue is making itself more of a comparable alternative to React that has tons of support for iOS and Android projects.

Making Developers’ Lives Easier

While a seemingly simple point, I think that this is the main pro of using VueJS — its simple, but powerful, capabilities. These were the aspects highlighted.

**Exposing the Reactivity API **— the new changes will give devs the ability to explicitly create reactive objects. As well as creating custom re-render hooks. 3.0 also addresses a common complaint of VueJS users: When and why the hell is my component re-rendering?

Now there is a renderTriggered event that allows people to see what is triggering the update. A fantastic feature that will give VueJS even more transparency.

So What?

You may be thinking, “So what? People are still going to use React or Angular.” and you may be right. As the current industry standards, React and Angular will likely continue to be the most popular options for component frameworks. However, there are a few interesting things to discuss in Vue 3.0 that may make it more of a competitive alternative in the coming years.

Speed. even now, VueJS provides faster render times than React or Angular. With the micro-optimizations that You discussed, it’s possible that Vue can have half the render times of the other frameworks. This is a key point that could draw some developers away from other environments. The table below shows the speed and memory advantage that Vue 2.0 already has — the new updates should improve these even more.

Adaptability. VueJS is designed to be easy to implement. Whether you want to add it to an existing project or use it to power a SPA, there is a lot of documentation and use cases that help define your needs. The changes made in Vue 3.0, especially exposing the reactivity hooks and a new modular design, make this already flexible language even more powerful. While I’ll go on to highlight the simplicity of VueJS, there are so many features that allow more technical and experienced devs to take full control of their project.

Documentation. This may be a “me issue”, but I personally find Vue’s documentation 10x easier to understand than React’s. In fact, I’ve never even had to complete a Hello World Tutorial or anything in Vue. The documentation was enough for me to understand my usage case and get started. You can take a look for yourself.

**Difficulty (or lack thereof) **— like I was talking about the documentation — Vue is super approachable. Not only does it use natural HTML, CSS/CSS preprocessors like sass and scss, and Javascript, but it also comes with a decent amount of support and libraries for a relatively new framework. It’s super easy to jump in for new developers and is very scalable for advanced ones.

To see the full impact of Vue 3.0, we’ll have to wait until its release sometime (hopefully) in 2019. The features that Evan You showed off at VueConf Toronto seem to make Vue more powerful and efficient, so my hopes are high for the new release. What are your thoughts on Vue 3.0 and the great Vue v. React v. Angular debate?

Ember.js vs Vue.js - Which is JavaScript Framework Works Better for You

Ember.js vs Vue.js - Which is JavaScript Framework Works Better for You

In this article we will discuss full details and comparison of both Ember.js and Vue.js

JavaScript was initially created to work for web applications. But today they have become the favorite of mobile app developers. Most of the developers prefer to work with frameworks based on JavaScript. It simplifies coding. You can use JavaScript with almost any framework.

The use of a particular framework will decide how easy and fast it is to create the app. So, you must choose the best one suited for the app that you are planning to build. You must make a wise choice so that you benefit in the end. Among the crowded market, two of the frameworks stand out. We will make a comparison between Ember.js and Vue.js.

Why Do You Select A Particular Framework?

Before we start comparing the two frameworks, we should understand the factors that lead to the choice of a framework. Each developer chooses a framework before he or she goes to work on an app. Let us see the reasons for the selection.

● The codes must be easy to understand and transparent.

● The framework should give the maximum power with the least amount of coding.

● The framework should provide a well laid out structure to work on.

● Does the framework support an in-built router or an external plug-in router?

● The framework should be able to transfer more data on a full page-load so that it becomes a single-page app. A single-page app is more beneficial for the application.

● In single page architectures if there is a need for users to share links to sub-screens within the interface, then the framework should have the capacity to route based on the URL.

● A tighter template option can help in enabling two-way binding.

● The framework should not conflict any third-party library.

● Testing the codes inside the framework should be easy.

● The framework should provide the HTTP client service for AJAX calls

● The documentation is essential. It should be complete and up-to-date.

● The framework should be compatible with the latest version of the browser.

● The framework has to fulfill the above conditions for easy construction of the app. You must ensure that the framework you choose meets the conditions.

Vue.js Explained

Developers are always looking at new frameworks to build their apps. The main requirements are speed and low cost. The framework should be easy to use by even new developers. You should be able to use it at low cost. Other considerations are about simple coding, proper documentation, etc.

Vue.js combines a lot of good when it comes to software language for web app development. The architecture of Vue.js is easy to put in use. The apps developed using Vue.js are easy to integrate with new apps.

Vue.js is a very lightweight framework. It makes it fast to download. It is also much faster than other frameworks. The single-file component nature of the framework is also beneficial. The size has made it very popular.

You can further decrease weight. With Vue.js you can separate the template-to-virtual DOM and compiler. You can only deploy the minified and zipped interpreter which is only 12 KB. You can compile the templates in your machine.

Another significant advantage of Vue.js is that it can integrate easily with existing applications created with JavaScript. It will make it easy for using this framework to make changes to applications already present.

Vue.js also integrates easily with other front-end libraries. You can plug in another library and make up for any deficiency in this framework. This feature makes this tool a versatile one.

Vue.js uses the method of rendering on the streaming-side server. You can render your component and get a readable stream. You can then send this to the HTTP server. It makes the server highly responsive. Your users will get the rendered content very quickly.

Vue.js is very SEO friendly. As the framework supports server-side rendering, the views are rendered directly on the server. The search engines list these.

But the most important thing for you is the ease with which you can learn Vue.js. The structure is elementary. Even new developers will find it easy to use it to build their apps. This framework helps in developing both small and large templates. It helps to save a lot of time.

You can go back and check your errors very easily. You can travel back and inspect all the states apart from testing your components. It is another important feature as far as any developer is concerned.

Vue.js also has very detailed documentation. It helps in writing your applications very quickly. You can build a web page or app with the basic knowledge of HTML or JavaScript.

● Vue.js has pure architecture. It helps in integration with other apps

● Vue.js is lightweight and fast. It can be made lighter by deploying only the interpreter

● You can separate the compiler and the template-to-virtual DOM.

● Due to smooth integration, you can use this to make changes to existing apps

● To make up for any shortfall, you can plug-in any library and makeup.

● As Vue.js uses streaming-side server rendering, your users can get quick responses.

● The server-side rendering also helps in being ranked higher by search engines.

● It has a simple structure. Easy to use for any new developer

● You can go back and check and correct your errors.

● You can check all the existing states.

● Detail documentation also helps build the web page or application very quickly.

Ember.js Decoded

Ember.js is an MVVM model framework. It is open-source software. This platform is mostly used for creating complex multi-page applications. It maintains up-to-date features without discarding any of the old features.

With this framework, you have to follow the architecture of the framework strictly. The JS framework is very tightly organized. It reduces the flexibility that other frameworks might offer.

There is a very refined and developed control system for its platforms and tools. You can integrate it with the new version with the tools provided. There is strict guidance about avoiding outdated APIs.

You can understand Ember’s APIs easily. They are also easy to work. You can make use of highly complex functionalities simply and straightforwardly.

The performance is better as similar jobs are processed together. It creates batches of similar bindings and DOM updates to improve the performance. It means that the browser needs to process them in one go. It will avoid recomputing for each task, wasting a lot of time.

You can write the codes in a simple manner and modules. You can use any of Ember’s APIs. It is possible due to the presence of Promises everywhere.

Ember comes with a well-written guide. The API is recorded in a useful manner. It is a front-end framework that is loaded. Ember has a router, pipeline, services, etc. of its own.

The basis for views, controllers, models, and framework is the Ember Object Model. All components come from the same objects. The framework is firm and steady. The reason is that all elements have similar jobs and characteristics.

Ember has made the general application, organization, and structure clear so that you don’t make any mistakes. You will have no chance to complicate the application unnecessarily. If you have to go out of the defined limits, you will have to force your way out.

The language used for templating in Embers is Handlebars. This language helps Embers to keep its logic out of view. The clean syntax of Handlebars makes it easy for you to read and understand the templates. Handlebar templates are faster to load.

Another advantage you gain from Handlebar is that you don’t have to update your template every time you add or remove data from the page. It will be done automatically by the language itself.

A community that is continually improving the framework supports Ember. They are updating the framework with the latest technology. They also make sure that backward compatibility is possible.

● Ember.js is an open-source MVVM model framework suitable for complex multiple-page applications.

● It offers both the latest and old features.

● It has a very tightly structured framework which doesn’t offer much flexibility

● A very refined control system helps you to integrate with new versions without any problem.

● There is strict guidance about avoiding outdated API versions.

● Ember’s APIs help you to use complex functionalities in a simple manner

● There is no recomputing for each task as the framework allows the browser to do similar functions together.

● Promises allow you to write modular and straightforward code using any API of Ember.js.

● Ember.js is a fully loaded, front-end framework.

● The framework is stable because all components have the same functionalities and properties.

● It has well-defined limitations which will prevent your complicating your application

● Handlebars, the language used by Ember.js allows you to read and understand templates easily. It also helps to load the templates faster.

● Handlebars will ensure to update the template every time you add or remove data.

● Ember.js has an active community that updates the framework regularly and facilitates backward compatibility.

A Comparison Between Ember.js And Vue.js

This article intends to compare the features of both frameworks. Let us see how the characteristics of these frameworks compare. It will help you to make use of the right framework for your web application.

When you need a modern engine for an old application, it is Vue.js which will help you. It combines the best properties of other frameworks. Vue.js is a developing framework. A ready-to-use library of interface elements does not exist. However, many third-party libraries can help you.

Ember.js offers you a well-organized and trustworthy framework. When the development team is big, this is the framework that suits best. It allows everyone to understand the written code and contribute to a common project. The technology will be up-to-date, and the platform will be stable.

Vue.js can help you use the syntax of different kinds. It helps in writing the codes with ease. It is also an SEO friendly framework. Ember is a fully loaded front-end framework and can help you develop the applications very fast. But it is not suitable for developing small projects.

It is not easy to say this is better than that. It will depend on what kind of project you have undertaken. Both have their pluses and minuses. The below table will help in a better comparison.

Final Thoughts

It is not easy to conclude as to which is better. It all depends on the application that you want to develop. Both frameworks are developing. Both are getting updates. Both the communities are working on the frameworks.

While Vue.js is more comfortable for writing codes, Ember is a full-stack framework allowing the development of apps very fast. It is suitable for big projects. It is too complicated to be used for smaller projects.
