  • MongoDB is the no SQL database. It uses JSON style documents for the data representation. The reason of choosing Mongo is that, it lets you make the use of just one language the whole way through. Whether you should select the tool as per your requirement.
  • Express.Js is a HTTP server framework for web applications that gives useful modules and components to work upon the common task for the website. It gives you the simple interface so that you can make request endpoints and cookie handling. Apart from that, it is good at enabling the simple REST routes, handling automated HTTP header and supporting Connect middleware to plug in synchronous functions in order to manage the requests and responses.
  • Angular.Js is a frontend JS framework to develop complex client side applications with modular code and data binding UI. It is used to develop the single page applications with the use of the MVC architecture; and maintained by Google. It improves the structure of the code and makes the testing easier with the dependency injection.
  • Node.Js is a concurrent JavaScript environment for building scalable and fast web applications. It compiles the JavaScript code to native machine code before the execution. It is lightweight and perfect for the real time applications.

We provide either complex MEAN stack development or use its components like Node.Js or Angular.Js in conjunction with other technologies.

Rich Internet Applications

  • html 5 application development
  • html 5 application development, angular, knockout

New HTML5 features of modern browser move web applications development to a new level. Now it is possible to implement very complex applications and run them in browser just with HTML and JavaScript. We offer professional HTML5 application development with modern technologies like Angular.Js, Knockout.Js, Backbone, Require.Js, TypeScript, LESS, jQuery, RxJS and other.

Experienced HTML/JavaScript developers and QAs know how complex JavasScript application can be and how many defects can be missed during development and discovered only on runtime. However, web applications development with modern technologies like TypeScript and LESS allows us to discover the simplest errors during compilation. Such approach decreases number of bugs and development–testing cycles. It allows us to save your money and deliver project earlier.
