I am learning ember.js, and I am trying to understand the difference between a view and a component. I see both as a way of making reusable components.
I am learning ember.js, and I am trying to understand the difference between a view and a component. I see both as a way of making reusable components.
From Ember's website on views:
Views in Ember.js are typically only created for the following reasons:
-When you need sophisticated handling of user events
-When you want to create a re-usable component
From Ember's website on components:
So what is the main difference between a view and a component? And what would be a common example where I would prefer to use a view over a component and vice versa?
npm has become the world’s largest module system with 700,000 usable packages on npmjs.com and billions of downloads every month.
Please accept the following terms and conditions before reading this article!…
A library is an organized collection of useful functionality. A typical library could include functions to handle strings, dates, HTML DOM elements, events, cookies, animations, network requests, and more. Each function returns values to the calling application which can be implemented however you choose. Think of it like a selection of car components: you’re free to use any to help construct a working vehicle but you must build the engine yourself.
Libraries normally provide a higher level of abstraction which smooths over implementation details and inconsistencies. For example, Ajax can be implemented using the XMLHttpRequest API but this requires several lines of code and there are subtle differences across browsers. A library may provide a simpler
ajax() function so you’re free to concentrate on higher-level business logic.
A library could cut development time by 20% because you don’t have to worry about the finer details. The downsides:
A framework is an application skeleton. It requires you to approach software design in a specific way and insert your own logic at certain points. Functionality such as events, storage, and data binding are normally provided for you. Using the car analogy, a framework provides a working chassis, body, and engine. You can add, remove or tinker with some components presuming the vehicle remains operational.
A framework normally provides a higher level of abstraction than a library and can help you rapidly build the first 80% of your project. The downsides:
A tool aids development but is not an integral part of your project. Tools include build systems, compilers, transpilers, code minifiers, image compressors, deployment mechanisms and more.
Tools should provide an easier development process. For example, many coders prefer Sass to CSS because it provides code separation, nesting, render-time variables, loops, and functions. Browsers do not understand Sass/SCSS syntax so the code must be compiled to CSS using an appropriate tool before testing and deployment.
The distinction between libraries, frameworks, and tools is rarely clear. A framework could include a library. A library may implement framework-like methods. Tools could be essential for either. I’ve attempted to label each project but the scope can vary.
Projects in approximate order of usage/popularity/hype…jQuery
React usage appears low in statistics perhaps because it’s used in applications rather than websites. Almost 70% of developers claim to have some experience using the library.
Angular is the first framework – or MVC application framework – to appear on this list. The most popular edition remains version 1.x which extended HTML with two-way data-binding while decoupling DOM manipulation from application logic.
Angular 1.x is still in development despite the release of version 2 (which is now version 4!) Confused? See below…
Angular 2+ is radically different to v1. Neither is compatible with the other – perhaps Google should have given the project a different name?!
Vue.js is a lightweight progressive framework for building user interfaces. The core offers a React-like virtual DOM-powered view layer which can be integrated with other libraries but it is also capable of powering single-page applications. The framework was created by Evan You who previously worked on AngularJS but wanted to extract the parts he liked.
Ext JS evolved from YUI-Ext and has one of the longest histories on this list. Although best known for its wide range of configurable, accessible, cross-browser UI components and data visualisation tools, Ext JS also provides a framework for building full applications. Alternatively, you can use the component library with React or Angular.
Ext JS is the only framework here to offer commercial training and support. There are also options to have the Sencha team help review your code, automate testing, and migrate to other platforms.
Client-side usage is low but either library can be adopted for server-side Node.js applications.
Backbone.js was one of the earliest client-side options to provide an MVC structure commonly found in server-side frameworks. Its only dependency is Underscore.js which was created by the same developer.
Backbone.js claims to be a library because it can be integrated with other projects. I suspect most developers consider it to be a framework, albeit less opinionated than some others.
Ember.js is one of the larger opinionated frameworks which is based on a Model-View-ViewModel (MVVM) pattern. It implements templating, data-binding, and libraries in a single package. The convention-over-configuration concepts will be immediately familiar to those with Ruby on Rails experience.
One of the older MVVM frameworks, Knockout.js uses observers to ensure the UI stays synchronized with underlying data. It features templating and dependency tracking.
Hungry for more? The following projects are less popular but worth
Build tools automate a variety of web development tasks such as pre-processing, compilation, module bundling, image optimization, code minification, linting, and running tests. Tasks are usually managed together in a single executable package. The most popular options:Webpack
npm is the Node.js package manager but its scripts facility can be used for general-purpose task running. It’s an attractive option for simpler projects with few dependencies. However, more complex tasks can rapidly become impractical.Grunt
Browserify supports CommonJS modules as used by Node.js to compile all modules into a single browser-compatible file.RequireJS
Linting analyses your code for potential errors or deviation from syntactical standards. You’ll never miss a closing bracket or undeclared variable again!ESLint
ESLint is the most popular linting tool supported by the majority of IDEs, editors, bundlers, and task runners. Every rule is a plugin so it can be configured to your liking.JSHint
Test-Driven-Development requires you to write code to test your code before you start writing it. You’re welcome to write code to test your test code too!
A testing framework from Facebook which has risen in popularity because of its close connections with React and Webpack.Mocha
Mocha can run tests in Node.js and a browser. It supports asynchronous testing and is often paired with Chai to enable test code to be expressed in a readable style. It was the most popular option for several years.Jasmine
If you follow the wisdom of crowds, momentum is currently behind React and other libraries are moving in a similar technical direction. It’s a safe career choice but you should also consider Vue.js or the React-compatible-but-smaller Preact.
Monolithic frameworks have fallen from favor but, should you require a strict structure for larger projects, AngularJS remains a popular option. The majority of developers have stuck with version 1.0 but that’s possibly out of necessity than choice. Longer term, version 2+ could be a safer bet but you will need to learn TypeScript.
Sencha’s Ext JS is a great option for companies (small businesses to enterprises) looking for an option that includes both a framework and pre-built, integrated components and tools, including access to commercial support. Ext JS also easily integrates its robust component library with React and Angular, for developers looking to implement pre-built components as opposed to building them on their own.
Do not discount jQuery. It’s not trendy and is rarely mentioned in the technical press, but it’s actively developed and more than capable for websites and applications. jQuery has a shallow learning curve and is understood by many developers worldwide.
Tools choice is less critical and can vary from project to project. Most WebPack, Gulp or npm scripts. You can’t go far wrong with ESLint and Jest for testing but there are plenty of alternatives to try.
That said, every project, team and skill set is different. You have limited time to make an assessment so it’s tempting to use what you know. This article will receive comments recommending FrameworkX but everything looks like a nail when you have a hammer.
Like most things in life, a variety of choices informs a toxic culture of mine is better than yours and you’re wrong and I’m right.
Since technology advancements have got us in this mess, is there any chance it could get us out of it as well?
Enter Microfrontends…Introduction to Microfrontends
Modern UI development regardless of your framework has became all about component composition: You adapt to a framework’s way of doing things by following their patterns and conventions to create components usually underpinned by some sort of data model usually in the form of a service or state object.
For example: Angular has a strong opinion on how everything should be architected in the frontend. React although it only deals with components has a huge ecosystem backing it driven by a community of React-centric developers.
**Microfrontends **have gathered huge momentum recently as away of allowing multiple teams to work on a single UI using multiple frameworks, but could it really change the landscape of UI development?
In this article, I am going to spend some time looking at the SDLC (software development lifecycle) and the advantages of adopting such an architecture.Where’s the problem?
The current trend in UI development, is to build a feature-rich and powerful browser application (single page application) using a chosen framework.
Development results in building lots of little components which are then bundled together in some sort of build process using something like webpack or rollup.
Over time the UI layer often developed by separate or multiple teams, grows and gets more difficult to maintain creating a huge monolithic frontend.
Monolithic frontend SDLC
Monolithic frontends deployment architectureReversing the microservice anti-pattern:
Microfrontends looks at removing that monolithic build step, and results in completely decoupled services that can be independently built and deployed:
Microfrontend deployment architecture
Now our UI architecture has all the qualities of traditional microservices:
Since we have decoupled our UI components into many microfrontends, we no longer have to dictate which framework each component uses.
The below illustration shows how we could potentially have different application teams using different technologies to create their independently built and released microfrontend:
SDLC using multiple frameworks
There are **several ways **to solve this using technologies but let me illustrate one example:
Once we have released our microfrontends, we should compose them together in a single UI layer. The communication between the microfrontends should be handled by the composition layer which should have a well defined contract.
Deployment architecture using multiple frameworks
From a user perspective they access a single application, but the developer’s ability to solve a problem is no longer limited by what single framework the application uses.

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