Building Web Apps With Yeoman And Polymer: Scaffold your webapps with modern tooling

Building Web Apps With Yeoman And Polymer: Scaffold your webapps with modern tooling | Mobile Apps | Scoop.it

Tooling for scaffolding Polymer web apps

As I mentioned earlier, Polymer is a library of polyfills and sugar which enables the use of Web Components in modern browsers. The project allows developers to build apps using the platform of tomorrow and inform the W3C of places where in-flight specifications can be further improved.

generator-polymer is a new generator for Yeoman that helps you scaffold out Polymer apps using Yeoman, letting you easily create and customize Polymer (custom) elements via the command line, and import them using HTML Imports. This saves you time by writing the boilerplate code for you.

Developing mobile apps with Node.js and MongoDB, Part 2: Hints and tips

Developing mobile apps with Node.js and MongoDB, Part 2: Hints and tips | Mobile Apps | Scoop.it

Get implementation details on using Node.js (server-side JavaScript), rather than Java technology, to develop systems of engagement. In this article, the IBM Extreme Blue team who developed a RESTful backend application using Node.js and MongoDB shares their thought process and recommendations.

In this article, we share lessons we learned in the process of developing a RESTful backend application using Node.js and MongoDB. We highlight our thought process in several high-level design and implementation decisions. We'll cover these topics:
* Leveraging NPM (Node Packaged Modules)
* Understanding asynchronous programming
* Structuring a large Express.js application's routing configuration
* Application-level logging
* Approaching data persistence and modeling
* Solving Passbook-specific challenges including cryptographic functions not supported by Node
* And we address subtle "gotchas" in hopes of expediting the learning process for those interested in Node.js and MongoDB development:
* Don't make assumptions about objects or their properties in a dynamically typed language
* Avoid implicit control flow
* Understand your dependencies' behavior
