Functional approach. See More

Top Con

No support for legacy browsers

Deku does not support legacy browsers, or relatively old browsers for that matter. They only support the latest versions of the major web browsers. See More

Top Pro

Server side rendering

Deku can render it's components and data server side, then it sends those components as HTML to the browser. This ensures faster initial loading time and SEO friendliness out of the box, since it's indexed as any other static website by search engines. See More

Top Con

Not a lot of learning resources

Since it's a rather new library and has a small community, there are not many examples where you can learn from out there. There are also few guides and the documentation is not amazing and has some parts that should be covered better. See More

Top Pro

Easy to learn

Since Deku is very lightweight and has a rather small API, there's not much to learn. It's pretty easy to get started and build something with it. See More

Riot

Top Pro

Minimal DOM operations

Riot takes the expressions from a DOM tree and stores them in an array. Each of these expressions points to a DOM node. On each cycle these expressions are compared to the values in the DOM. So when a value has changed, Riot automatically updates the corresponding node. This way the operations are kept to a minimal amount and since the expressions can be cached, going through 1000 of them takes less than 1ms. See More

Top Pro

Lightweight

Riot is made to be used with websites of any kind, so it's built to be easy and lightweight, but still maintaining all the needed features for a UI library. It's only 2.5 KB in size when minified. So it can also be used for mobile web apps without requiring much bandwidth to download. See More

Top Pro

Components use familiar HTML tags

Riot components use custom tags which are nothing more than familiar HTML tags coupled with JavaScript. This eliminates the need to learn another templating language or syntax. For example: <todo> <h3>TODO</h3> <ul> <li each={ item, i in items }>{ item }</li> </ul> <form onsubmit={ handleSubmit }> <input> <button>Add #{ items.length + 1 }</button> </form> this.items = [] handleSubmit(e) { var input = e.target[0] this.items.push(input.value) input.value = '' } </todo> Riot tries to separate HTML and JavaScript, while still keeping them inside the component. This way, the HTML can also be neatly mixed with JavaScript expressions. See More

Top Pro

Supports server side rendering

Riot has support for server side rendering. The views and data are rendered on the server, then those views are sent as HTML to the browser when a user requests them. This helps with initial loading time and is very useful for SEO purposes because the web app is indexed by search engines same as other static websites that have their HTML on the server. See More

Top Pro

Easily pluggable with JS/HTML/CSS preprocessors

It is very easy to use your favorite preprocessors with the Riot compiler. Riot comes with CoffeeScript, ES6 (Babel), TypeScript, LiveScript and Jade support. You can also add your own parsers. See More

Top Pro

Very simple

It makes React look confusing as hell. Nothing against React - It's just that easy to implement! See More

Top Pro

Scoped CSS available in components

Riot supports scoped CSS inside components for every browser by rewriting stylesheet rules. See More

Top Pro

Separation of concerns with RiotControl

RiotControl is inspired by Facebook's Flux Architecture Pattern and it's a simple Central Event Controller/Dispatcher for Riot. It's extremely lightweight (like Riot itself) but unfortunately passes up on some features in favor of performance and simplicity. RiotControl helps with storing the stater of the application, by passing events from views to stores and vice-versa. Stores can communicate with many views and views can do the same with many stores, this enables to clearly separate concerns and inter-component communication. See More

Very useful. See More

Top Pro

Responsive server-side rendering

Since most of the mainstream server-side rendering implementations are synchronous, they can block the server's event loop when the application is complex. Vue implements streaming server-side rendering, which allows you to render your component, get a readable stream and directly pipe that to the HTTP response. This allows you to have a responsive server and decreases the time your users have to wait before they get your rendered content. See More

Top Pro

Supports inline templating

Although you can build components in JavaScript files, you can also use inline handlebars-like templating in your HTML views where simplicity is often a more sane choice. See More

Top Pro

Support for both templates and JSX

You can choose to use either a templating language, or if you feel it's necessary to drop on a lower virtual-dom level, you can use JSX. This is simply done by replacing the template option with a render function. Or alternatively, you can embed functions inside templates by using the <render> tag. See More

Some React components may not work with Inferno

Inferno and React have different public and private APIs. If 3rd party components use a private API then it's almost certainly going to break when you use it with Inferno. Once React Fiber is implemented, even libraries that are currently working will break and will not be supported by Inferno. See More

Knockout

Top Pro

Easy data binding

Knockout uses HTML5 data attributes to bind HTML elements to data objects in javascript. This allows more work to be done by the framework rather than requiring you to specify where data should be bound in the javascript. The data binding is very intuitive as the bindings are done within the HTML itself in the location it should be bound. See More

Top Con

Seems to be dead

KO has been stuck at version 3.4 for a long time, and there's not a lot of community activity. See More

Top Pro

Easy to learn

Has a low entry barrier and an easy learning curve. It's especially easy to learn for beginners. See More

Top Con

Slower than others when amount of objects grows

Knockout has a bad performance when the dealing with large amount of objects. You can see more here. See More

Top Pro

Legacy browser support

Supports a large number of browsers, including IE6. See More

Top Con

Can become complex once the application grows large

Knockout leaves the application structure to the developer and it can become quite complex and unmanageable in the hands of a beginner once the application grows large and complex. See More

Top Pro

Built in templating

Bindings in Knockout can also be used to control the generated structure of the HTML. There are bindings provided to allow for iteration and conditionals. The structure of the html reflects the structure of the data so iterative elements are bound to arrays in the data model. Having the HTML structure maintained by bindings keeps the templating simple, easy to read, and maintain. Knockout also allows for string based templating so you can use whatever templating library you prefer. See More

Top Con

Two way binding requires a little extra work

When allowing users to edit existing data, the two-way binding of observables means you'll need to have to save original values before they're edited, to make comparisons or revert if the user cancels the action. See More

Top Pro

Dynamic models help with keeping the code simple and clean

Models in Knockout can be watched to keep the page data up to date by using observable objects. The observables notify Knockout when data is changed and automatically updates the page when this happens. By having Knockout maintain this relation, it keeps the front end code cleaner and simpler, and by enforcing a consistent pattern with observables the methodology can be more robust. See More

Top Pro

Lightweight and plays nicely with other libraries

Top Pro

Great documentation

The excellent tutorials with built-in exercises are a great learning experience, even for people without prior MVVM and data binding experience. See More

Top Pro

It's only a library

Knockout does one thing, and does it well. It doesn't try to take on more than one area. It does MVVM data binding and that is it. See More

Top Pro

Conventions over configurations

Configured to give you the most common use cases by convention, which means you only need to change the default configuration for edge cases. This means that for normal cases far less boiler plate code has to be written. See More

Top Con

It would be great to have a lot of plugins made by the community, or video tutorials from experiences when using it. Hopefully in the near term future. See More

Top Pro

Out of the box ES6 support

Aurelia includes native support for ES6 and even comes with a Gulpfile which helps with transpiling ES6 code to ES5. See More

Top Con

Two-way data binding is often considered an anti-pattern

Two-way data-binding means that a HTML element in the view and an Angular model are binded, and when one of them is changed so is the other. One-way data-binding for example does not change the model when the HTML element is changed. This is a rather controversial subject and many developers consider two-way data binding an anti-pattern and something that is useless in complex applications because it's very easy to create complex situations by using it and being unable to debug them easily or understand what's happening by just looking at the code. See More

Top Pro

Standards compliant

Aurelia developers always try to keep within existing and emerging Web Standards, making it easier for developers to follow best practices in web development. See More

Top Pro

Good binding system

Clear, intuitive and HTML/SVG compliant binding syntax. Examples: Default binding => value.bind One Way binding => value.one-way Two Way binding => value.two-way One Time binding => value.one-time See More

Top Pro

Allows developers to build their application however they want

Aurelia is extremely unopinionated and was designed to be highly modular. This gives the developer the freedom to develop their application however they want, without forcing them in paradigms or rules predefined by the framework. Likewise, any of the individual components can be swapped out if so desired. See More

Top Pro

Easy to learn

Learning aurelia basically means learning EcmaScript and HTML, since aurelia is designed for standards compliance. Also, aurelia embraces upcoming ES language features by convention, such as ES class decorators for dependency injection, encouraging clean architecture and future-proof code. See More

Top Pro

Variable binding helps with self-documenting the code

The syntax used to bind variables within the application class is very similar to Javascript itself. You can specify the type of the binding you are using explicitly, which practically self-documents your code and makes it easy to understand whether a value is one-way or two-way binded. See More

Top Pro

Agnostic code

Most of the code you write is Aurelia-agnostic. That way you can easily test it, switch to another implementation and make it look clean (business oriented). Even the HTML. See More

Top Pro

Structure

Aurelia.js consists of modules that can be used as a full framework or separately. See More

Top Pro

Great documentation

One of the most crucial pieces of any new technology or framework is the documentation. At present even though Aurelia is pre-beta, the documentation is pretty complete. There are code examples missing and whatnot, but for the most part it is concise and makes the main parts of the application easy to understand. See More

Top Pro

Full commercial support

Aurelia is officially backed by Durandal Inc. and has commercial and enterprise support is available. See More

Top Pro

Data binding choices with sane defaults

Aurelia defaults to one-way data binding, alining with conventional wisdom. However, there are times when two-way data binding proves useful, such as binding an input widget with a view-model. Aurelia makes two-way data binding available to developers and uses it by convention when appropriate. See More

Top Pro

Plays well with other frameworks

Aurelia can be used alongside of React and Polymer, since it is designed for interoperability. In practice, this means Aurelia developers can use React components by including an Aurelia custom element: https://github.com/Vheissu/aurelia-react-example/blob/master/README.md It also works well with Polymer, since they are both based on the WebComponents standards: http://aurelia.io/hub.html#/doc/article/aurelia/framework/latest/integrating-with-polymer See More

React

Top Pro

Easy to reuse components

Since every single UI component is created independently in JavaScript, it becomes very easy to reuse them throughout your app without having to re-write them. See More

Top Con

Heavy on memory

React's virtual DOM is fast, but it requires storing elements in the virtual and real DOM increasing memory usage for the page. This can be a real problem for single-page webapps designed to be left running in the background. See More

Top Pro

Server side rendering

React can render it's components and data server side, then it sends those components as HTML to the browser. This ensures faster initial loading time and SEO friendliness out of the box, since it's indexed as any other static website by search engines. See More

Top Con

Verbose

React gets a little verbose as applications get more complicated with more components. It's simply not as straightforward as simply writing HTML and JavaScript would be. See More

Top Pro

Virtual DOM support

Instead of relying on the DOM, React implements a virtual DOM from scratch, allowing it to calculate precisely what needs to be patched during the next screen refresh. This is orders of magnitude faster than fiddling with the DOM itself. See More

Top Con

Not a complete solution

React does not do everything for the developer, it's merely a tool for building the UI of a web app. It does not have support for routing or models, at least not out of the box. While some missing features can be added through libraries, to start using React and use it in production, you still would need to have experience, or at least a good grasp on what the best libraries to use would be. See More

Top Pro

One-way data flow

React's one-way data binding (or one-way data flow) means that it's easy to see where and how your UI is updated and where you need to make changes. It's also very easy to keep everything modular, fast and well-organized. See More

Top Con

Large file size

React's react.min.js is 145.5KB in size. It's much larger than some other libraries that offer roughly the same features and it's almost the same size as some MV* frameworks such as Angular or Ember that offer more features out of the box. Although, it should be mentioned that sometimes having a smaller library may force developers to reinvent the wheel and write inefficient implementations on features that React already has. Ending up with a larger application that's harder to maintain and/or that has bad performance. See More

Top Pro

Functional programming style leads to less buggy UIs

Top Con

Renders too frequently

Top Pro

Easy to write tests

Since React's virtual DOM system is implemented completely in JavaScript, it's very easy to write UI test cases. See More

Top Con

You have to learn a new syntax

Requires learning a custom syntax, JSX, that has some gotchas and introduce complexity, a steeper learning curve, and incompatibility with other tools. Though you can opt out from JSX and use vanilla JS instead. But that is not recommended since it adds a lot of unneeded complexity which JSX tries to avoid. See More

Top Pro

Can be used with different libraries

ReactJS can be used independently as the only library for building the front-end, or it can be used alongside JavaScript libraries such as jQuery, or even Angular. See More

Top Con

Template(view) mixed into code

Top Pro

Supported by Facebook and Instagram

React is built by Facebook engineers initially to be used only for their inner projects especially to solve the problem of building large complex applications with constantly changing data. See More

Top Con

No support for legacy browsers

React has recently dropped support for Internet Explorer 8. While the library may still work on IE8, issues that affect only IE8 will not be prioritized and/or solved. See More

Top Pro

Template engine independent

React provides a template engine (JSX) which is easy to use. But it's not mandatory. See More

Top Pro

Good debugging tools

React has an official Chrome Extension which is used as a developing and debugging tool. It can be used to quickly and painlessly debug your application or view the whole application structure as it's rendered. See More

Top Pro

Flux architecture pattern

Flux is a platform agnostic pattern which can technically be used with any application or programming language. One of Flux' main features is that it enforces uni-directional data flow which means that views do not change the data directly. With React this is useful because this way it's easier to understand an application as it starts getting more complicated. By having two-way data binding, lead to unpredictable changes, where changing one model's data would end up updating another model. By using the Flux architecture, this can be avoided. See More

Ractive fully supports a templating language. To be more precise, views are written with a variant of Mustache, which is also extended to support inline JavaScript expressions. Soon it will be able to support other templating languages. See More

Top Con

Ractive's two way binding can be a source of bugs

Two-way data-binding means that a HTML element in the view and an Ractive model are binded, and when one of them is changed so is the other. One-way data-binding for example does not change the model when the HTML element is changed. This is a rather controversial subject and many developers consider two-way data binding an anti-pattern and something that is useless in complex applications because it's very easy to create complex situations by using it and being unable to debug them easily or understand what's happening by just looking at the code. However, this is the default behaviour which can be changed to have one-way data binding. See More

Top Pro

Makes it possible to handle user interaction in a readable, declarative fashion

Ractive has a concept of proxy events, which translate a user action (e.g. a mouseclick) defined via an event directive into an intention (e.g. 'select this option'). This allows you to handle user interaction in a readable, declarative fashion. on-click='activate' with arguments: on-click = 'activate: {{a}}, {{b}}' It's activate (and not click, nor your function name) that is the name of the handler event that will be fired for any registered handlers created via ractive.on('activate', your_handler) ractive.on('activate', your_another_handler) Of course, Ractive also supports method calls like on-click='toggle(foo)' See More

Mithril

Top Pro

Small, easy to learn API

Most other frameworks either offer a huge API to deal with model and view synchronization, or defer to other libraries & plugins to cater for relatively simple use cases. Mithril's API is tiny but complete. The natural reaction is to assume something is missing, but as you build you realise you incredibly fast, powerful and rich applications can be built using nothing but Mithril. See More

Top Con

Small API can make it unsuitable for larger more complex projects

Mithril's small API and small number of functions while helpful for small projects and applications where speed is needed, can add another layer of complexity in larger more complex applications where a more extensive API is needed out of the box. See More

Top Pro

Fast rendering

Mithril's loading times are very fast. This is because it's templates are compiled first and then served to the browser and because it uses a virtual DOM. The virtual DOM is a virtual tree containing all the nodes of the real DOM, every time anything changes in the virtual DOM, Mithril does not re-render the entire (real) DOM, instead it just searches and applies the differences. See More

Top Pro

No need to learn another syntax to write views

Most MVC frameworks use HTML templates to render their views. They are good and useful because they are easy to read and understand. But they add more complication to an app because it's practically a new language and syntax that needs to be learned. Mithril argues that separating markup from logic is just a separation of technologies and not concerns, so you can write Mithril views in JavaScript. Writing them in JavaScript also makes it easier to debug them (HTML templates can't be debugged). See More

Top Pro

Familiar to people used to MVC

Doesn't lock you into any complicated conventions or structures, only one function is required to create either a Controller or a View. You're free to implement your architecture exactly as you want, so you can focus on the purpose of MVC, making connections between computer data and stuff in the end user's head. See More

Top Pro

Great documentation

Mithril has a large and expansive documentation despite it's relatively small API. Mithril's GitHub repo has more documentation than actual source code. None of that documentation is auto-generated See More

Top Pro

Allows you to choose which JavaScript libraries to integrate in your project

Mithril gives to the developer the flexibility to chose the best JavaScript library to use for a specific task. A huge framework like Angular instead forces you to use their API, which does not necessarily evolve as fast as the JavaScript ecosystem. Therefore you may end up in case when you are stuck using an API which is just not the best in terms of performance See More

Allows a smooth transition from other UI frameworks

One thing you need to start using Mithril is just a DOM node. With Mithril a developer is able to introduce the library step by step. See More

Top Pro

Does not force you into a predefined structure

Mithril's API is pretty small compared to other frameworks. It forces developers to solve problems in JavaScript rather than in Mithril. Other frameworks with massive APIs force you to think in a way that suits the framework. Mithril doesn't do that. See More

Top Pro

Can be used without build systems

It's plain old JavaScript, can be used without webpack, gulp or grunt, just include it into your HTML and start writing your app. See More

Backbone

Top Con

Requires more coding compared to other frameworks

Because many features are not provided out of the box, you either have to write more base class code to get those features, or find a plugin that provides them in a way you like. It does not provide much structure either, things like memory management must be kept in mind by the developer, also the lack of view lifecycle management makes state changes prone to memory leaks. See More

Top Pro

Gives you the freedom to implement views however you want

A lightweight view class is provided but there is no default templating method implemented. Because views are minimal it allows for much more freedom to implement views however you would like, and because of this freedom it's possible to write views to more uniquely adapt to a problem. User interactions are done within an events object that allows these interactions to be segregated from the rest of the view code which makes the behavioral aspect of the view easier to read and manage. See More

Top Con

Can easily lead you to spaghetti code

Heavy event-binding can lead to unmanageable spaghetti mess. BB tempts users to overuse it for no reason. See More

Top Pro

Can be combined with any library you want

Backbone can be combined with any library of your choosing, giving you the ultimate flexibility in creating customized solutions for unique projects. Even the only two backbone requirements, jQuery and underscore can be replaced with equivalent libraries like zepto or lo-dash. See More

Top Con

No data binding

Backbone does not have data binding support. However, there are some libraries that can be implemented in order to have data binding in Backbone. Such as Epoxy See More

Top Pro

Large community

Backbone has existed longer than most frameworks, and has a large following of users and projects using it as a framework. See More

Top Pro

You can call underscore.js methods directly on Backbone objects

Backbone collections and models are extended by underscore.js method allowing you to call underscore methods directly on the Backbone objects. See More

Top Pro

Easy to interface with the API

Backbone provides Model and Collection classes that provide strong analogs to restful resources. These strong analogs allow you to interface more naturally with the API, and makes it easier to write custom behaviors for more complicated API interactions. Collections provide a variety of powerful manipulation methods that are integrated from the underscore library, that allow you to manipulate, sort, and filter collection data easily. See More

Top Pro

Easy to implement complex user interaction

Because all the state is managed by Models and Controllers, and they are extendable objects, you can isolate all the state logic onto those objects allowing the rest of the application to not worry about it. The app is simplified to just taking in input to modify the Models and Controllers, and updating the views to reflect them, but none of the state needs to be a concern outside of the Model and Controller classes. See More

Top Pro

Doesn’t force you into a particular coding style or paradigm

There is no “magic” happening below the surface: the source code is clear, readable and well commented. Backbone is also “lightweight” in the sense that it doesn’t require a ton of buy-in to use. It can be easily integrated into an existing page, and you can choose to only use certain components of the library (Views without Models or Collections, for example). While there are many frameworks that seem to be faster to get started with, Backbone’s lack of surprises, clear documentation, speed & flexibility make it a good fit for all types of apps. See More

Top Pro

Extendable with plugins

Because Backbone is so simple, and the different components are very well isolated, it is very easy to extend the functionality of Backbone. If you're writing your own extended code it's easy to keep it separated out, and share with the community. The community also has many plugins already available, which you can pick and choose to use to fit your programming style. See More

Top Pro

Easy to abstract interaction

All Backbone classes extend an events class that allows for listening and triggering functionality. Because all classes implement events by default it is easier to provide asynchronous communication between objects, and it allows better abstraction of interaction so the event emitting object does not need to know the structure or existence of the receiving object.

Elm

Top Pro

No run-time exceptions

Lack of run-time exceptions makes it easy to produce large swathes of reliable front-end code without drowning in tests. See More

Top Con

Poor Windows support

Few if any of Elm's core contributors are Windows users and breaking bugs are sometimes left for weeks or months. See More

Top Pro

Inferred static typing

ML static typing is great because it's always there, you just choose how explicit you want to be and how much you want the compiler to do. See More

Top Con

Adds an additional layer of abstraction

Some users claim that Elm adds an additional layer of abstraction, meaning that it is one more hurdle between the brain and the product. See More

Top Pro

Designed around high-level front-end development

As Elm was designed as a front-end langauge, it has out of the box support for things like DOM-element creation, letting programmers focus on their application logic, rather than implementation details specific to the web. See More

Top Con

Not database-friendly

It is lots of work to make a server or database your "one source of truth", as Elm makes you write endless JSON parse boilerplate to talk to the server. See More

Top Pro

Great and simple way to learn Purely Functional Programming

You can try to apply some functional programming ideas in other languages that have an imperative basis, but you haven't seen the real power unless you tried it in the environment of purely functional programming. Elm is a simple language with great learning resources and easy graphical output, which makes it easy to explore the power of functional programming. Plus programming in Elm is very readable. See More

Top Pro

Growing community

Top Pro

Good documentation

Elm is gaining popularity, somewhat faster than many of the other solutions here. This translates to more code examples, more documentation, and more libraries. See More

Top Pro

High-level Functional-Reactive Code

Build animations, games, and interactions with an incredibly small amount of terse, readable code. See More

Top Pro

Super easy refactoring with very helpful compiler errors

In no other language you can refactor so easy without any worries, since the compiler will guide you through. It is like TDD but than compiler-error driven. See More

Top Pro

Static module system

Elm uses easy to use modules. Use: import List import List as L import List exposing (..) import List exposing ( map, foldl ) import Maybe exposing ( Maybe ) import Maybe exposing ( Maybe(..) ) import Maybe exposing ( Maybe(Just) ) Creation: module MyModule exposing (foo, bar) See More

Top Pro

Interactive Programming and Hot Swapping

Support for hot swapping and interactive programming is included. See More

Top Pro

Good tooling

All major editors have great support. With Atom for example, Elm plugins are available for linting, formatting, make/compiler support and Elmjutsu will simply overflow you with super useful functions, like navigate to referenced definition and show expression type. See More

Top Pro

Missing Syntactic sugar

Easy to learn, most functions have only one way, not 5 alternatives where you must study where to best use what. See More

Top Pro

Not quite Haskell semantics

Luckily you do not have to learn Haskell to be able to do any Elm. It is meant to be a language that compiles to Javascript, so for Javascript programmers (Front end) not for CS students who want to learn as many different algorithms as possible. See More

Ractive

Top Con

Ractive's two way binding can be a source of bugs

Two-way data-binding means that a HTML element in the view and an Ractive model are binded, and when one of them is changed so is the other. One-way data-binding for example does not change the model when the HTML element is changed. This is a rather controversial subject and many developers consider two-way data binding an anti-pattern and something that is useless in complex applications because it's very easy to create complex situations by using it and being unable to debug them easily or understand what's happening by just looking at the code. See More

Top Pro

Live, reactive templating

Ractive.js is a template-driven UI library, but unlike other tools that generate inert HTML, it transforms your templates into blueprints for apps that are interactive by default. See More

Top Pro

Powerful and extensible

Two-way binding, animations, SVG support and more are provided out-of-the-box – but you can add whatever functionality you need by downloading and creating plugins. See More

Top Pro

Supports a true templating language

Ractive fully supports a templating language. To be more precise, views are written with a variant of Mustache, which is also extended to support inline JavaScript expressions. Soon it will be able to support other templating languages. See More

Top Pro

Virtual DOM

Instead of relying on the DOM, Ractive implements a virtual DOM from scratch, allowing it to calculate precisely what needs to be patched during the next screen refresh. This is orders of magnitude faster than fiddling with the DOM itself. See More
