Full support for Typescript built in
Ranked in these QuestionsQuestion Ranking
Pro Out of the box Typescript support
Full support for Typescript built in
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.
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.
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.
Pro Good binding system
Clear, intuitive and HTML/SVG compliant binding syntax.
Default binding => value.bind
One Way binding => value.one-way
Two Way binding => value.two-way
One Time binding => value.one-time
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.
Pro Variable binding helps with self-documenting the code
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.
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.
Pro Full commercial support
Aurelia is officially backed by Durandal Inc. and has commercial and enterprise support is available.
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.
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.
Aurelia.js consists of modules that can be used as a full framework or separately.
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:
It also works well with Polymer, since they are both based on the WebComponents standards:
Pro Powerful helper CLI available
The CLI helps rapid creation of projects with generators, building, deploying and hot reloads. Webpack should be coming soon.
Pro Based on web components
Web Components are a collection of specifications released by W3C as a way to reduce the complexity of web apps by creating reusable components. Browser support is currently poor for web components, however Polymer is developed to make web components compatible with modern browsers.
Pro Various basic components
It provides a base component.
Pro HTML markup is not string
HTML markup as it can be a non-string.
Pro CSS is easy to apply
CSS can be applied far more comfortably than React.
Pro Flex layout components
It provides Flex layout components.
Pro Excellent documentation
Polymer guides you as with tools (cli, build environment, app templates,..) as with complimentary documentation on all phases of app development from creation of app as progresive web app to production deployment instructions.
As Polymer is standards based, the whole community around those standards also helping in documentation and support.
Pro Complete web app stack support
Full app stack from data tier to routing, progressive web app, responsive layouts makes no need to seek outside of Polymer ecosystem for application features.
In addition to waste set of mature web components in Polymer Elements along with Vaadin Elements there are thousands of web components in the wild comparable to jQuery plugins set.
Pro API is easy to understand, based on standard
The Polymer APIs are split on application layers and follow standards on all possible ways: Web Components, CSS variables, async API via Promises and so on.
Pro Excellent routing
The router is embedded into CLI for project creation and covers as web as Progressive web app, also fused with Polymer layouts out of the box. The shop template for CLI has a complete solution including the routing.
Pro No need for special debugging tools
The presence od specialized debugging tools are advertised by competitors. The all features of web components are natively supported by browser embedded development tools.
Con No big success stories yet
There are no notable big web products build with aurelia yet
Con Needs more support from the community
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.
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.
Con No server-side rendering
Polymer does not support server-side rendering. This results in higher loading times, more HTTP requests and it's not very SEO friendly, since search engines have no way of indexing a page if it's not rendered in the server.
