For the past several months I have been evaluating potential frameworks which could facilitate the implementation of context aware Web Components such that each component can be assembled declaratively into recombinant features and higher-level applications. After a focused period of prototyping each candidate framework, Polymer 1.x has proven to be the most effective approach to satisfy these particular design goals, and many others as well.
While I have also been leveraging Angular 2 for implementing self-contained Web Applications which need not be composed outside the scope of the application’s root component / template, the requirement to provide elements which can be arbitrarily composed within an html document declaratively or imperatively independent of using any one particular framework is one which proves somewhat challenging; yet, can easily be satisfied by leveraging Web Components, and Polymer simplifies the process of doing so considerably.
On a high-level, Polymer provides some much welcomed sugaring over the four Web Component specifications; HTML Templates, Shadow DOM, HTML Imports, and Custom Elements, respectively. The higher level abstraction and API offered by Polymer significantly simplifies the process of Web Component development, while reducing the time and effort required to meet both simple and complex use-cases alike.
Features provided out-of-the-box embrace that which developers have come to expect from a modern library or framework, such as one-way and two-way binding annotations, template helpers, a Local and Light DOM API, declarative and imperative event mappings, declared properties with observers and attribute reflection, and much more.
Add to this the growing Catalog of Elements provided by the Polymer Project, a complete Web Component Testing solution via WCT, optimization features such as Vulcanization with tooling support for Gulp, API Documentation components via Iron Component Page (though still pending ES6 Support) concise documentation with easy to use examples, and developers are afforded a rather elegant solution for building high quality, future facing Web Components, today.
In addition, Polymer comes in three specific layers, each of which builds upon the previous lower-level implementation. This allows for a nice level of flexibility in choosing the most appropriate implementation based on your specific needs. Depending on what is required, one can choose from the mirco-implementation for providing basic custom element sugaring, the mini-implementation for more advanced local DOM and life-cycle hooks, and the standard-implementation which provides the full suite of Polymer features.
Given the capabilities Polymer has to offer, as well as the growing number of organizations using Polymer, and some rather interesting applications being built with Polymer, if you haven’t already, I highly recommend given it a try.
So what does any of this have to do Chuck Norris?
Well, nothing actually.
Except, like Chuck Norris, Polymer is cool – very cool, and so after accidentally coming across the ICNCB service, I thought a simple Web Component which displays some comical facts about Chuck Norris could serve as a useful Polymer example.
And so, if you like to laugh a bit while learning something new, feel free to clone the repo over on Github to get familiar with a few of Polymer’s general capabilities, or simply check out the app here and have a few laughs.
