Over time, it has become a popular choice by front-end developers that need to bridge backend data stores with single-page applications (SPAs) and mobile apps. All GraphQL operations are tunneled through a single HTTP POST or GET-based URL. Requests use the GraphQL query language to

Many web-based user interfaces now make use of some form of single-page application framework, which does away with the concept of an application consisting of different web pages. Instead, you have a more powerful user interface, where everything

kind of web application you build. In broad terms, there are two kinds of web application: round-trip and single-page. Understanding Round-Trip and Single-Page Applications For a long time, web apps were developed to follow a round-trip model. The browser requests an initial HTML document from the server. User

because each HTML document has to be self-contained (leading to a lot of the same content being included in each response from the server). Single-page applications take a different approach. An initial HTML document is sent to the browser, but user interactions lead to Ajax requests for small fragments of HTML

and idiosyncrasies, have led a significant majority of developers to work on HTML5-based web apps that behave in a similar fashion to native apps.

concerns in your application, leaving you with code that is more maintainable in the long term. Developers commonly use libraries like Backbone.js to create single-page applications (SPAs).

more interactive, an MV* framework may be overkill. There certainly are complex Web applications where the partial rendering of views can be coupled with a single-page application effectively, but for everything else, you may find yourself better sticking to a simpler setup. Maturity in software (framework) development isn’t simply about how

and the general responsiveness of the user experience. A trend to improve perceived latency in the past few years has been to move towards building Single Page Applications (SPAs) - apps which after an initial page load are able to handle subsequent navigations and requests for data without the need for a complete reload

…

. Recall that Controllers respond to requests and perform appropriate actions which may result in changes to the Model and updates to the View. In a single-page application, rather than having requests in the traditional sense, we have events. Events can be traditional browser DOM events (e.g., clicks) or internal application events
