Koa.js is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. It is an open source framework developed and maintained by the creaters of Express.js, the most popular node web framework.
npm install koa
Koa provides a Request object as the request property of the Context. Koa's Request object provides helpful methods for working with http requests which delegate to an IncomingMessage from the node http module.
Augmented reality (AR) is the idea of mixing computer-generated media (e.g., 3D objects, 2D content, spatialized audio) with someone’s view of the real world. Whether you want to create a new AR application, or add an AR view to an existing web application, the argon.js framework provides a set of abstractions and utilities for adding an AR view to your web application in a platform- and technology-independent way.
Argon.js was originally designed to take advantage of the augmented reality capabilities of the Argon AR-enabled web browser on iOS, simplifying the process of delivering mobile AR experiences without the need to create, ship and support native applications.
However, argon.js will also work with other web browsers, taking advantage of their capabilities to allow your application to deliver whatever kind of AR experience each browser is capable of. While the AR capabilities a most web browsers is currently minimal, they are improving rapidly, and argon.js is designed to support this evolution.
AR.js is a solution for efficiently doing augmented reality on the web.
The goal is to make it easy for people to do augmented reality; AR that can be easily experienced on today’s phones and easily designed using web technology. The AR.js project is about enabling those people. So now, anybody with a modern phone can enjoy open-source AR, free of charge, cross-platform and without installation.
AR.js is fast. This is the first time that we have an open-source web-based solution capable of doing 60fps on currently deployed phones.
Suddenly, most people have a phone capable of doing AR without installation. This was not possible before. You don’t have to wait for everybody to buy AR-enabled devices (such as Tango, Moverio…etc.)
AR.js would not have been possible without some inspiring projects that came before. It is thanks to the hard work of others, that we can today reach 60 frames per second AR.
These projects helped make it possible:
Three.js is a great library for creating 3d graphics on the web
ARToolKit has been in development for years for augmented reality
Aurelia is a next generation UI framework. Whether you're building apps for the browser, mobile or desktop, Aurelia can enable you to not only create amazing UI, but do it in a way that is maintainable, testable and extensible.
Meteor.js is a cohesive development platform, a collection of libraries and packages that are bound together in a tidy way to make web development easier. It builds on ideas from previous frameworks and libraries to offer an easy way to start a prototype app, but it gives you the tools and flexibility to build a full fledged production app. There are libraries like Tracker and Blaze that the Meteor Development Group has built specifically for a reactive front-end experience.
Meteor.js is an open-source platform built on Node and MongoDB. It’s not just a framework, it’s more than that.
Is it comparable to Angular? Angular handles just the frontend parts of application. Meteor is more of a platform than Angular. It is both server and client-side code and handles a lot of the parts of applications that we need to create manually in Angular.
