One of the latest cool APIs of the modern web is web sockets API. It allows creating real-time apps, where users can collaborate, get notifications and data updates whenever the data is changed. This article will show how you can create a simple web chat by using Webix and web sockets API.
Web chat is a “hello world” for real-time web apps. You can grab the final code from github.
HTML5 provides multiple ways of arranging elements on the page. However, while building web apps we can still face tasks that can’t be solved with pure HTML and CSS. For example, there’s a problem of mixing percent and fixed size values in the same row. Another task that exercises the developers’ minds is making columns of equal height. The CSS Grid specification looks like a promising solution to such problems, but it’s currently at the draft stage and implemented only in Internet Explorer. If you need to have a greater layout flexibility here and now – that is where Webix Layouts can help.
Modern web apps can be rather complicated. It’s not uncommon that a single page can consume data from multiple sources, part of which can be provided by third party API or by a related application that resides on some other site. And that is where a problem occurs. A page hosted on one domain can’t access data from a different domain.
For example, if you have a page hosted on //app.mydomain.com, which tries to load data from the //data.mydomain.com, the data loading will fail. Any browser blocks such kind of data loading operation for safety reasons. Moreover, a request to a different port, such as //app.mydomain.com:5000 for example, will be blocked as well. URLs pointing to the same domain but to different ports are treated as URLs pointing to different domains.
Webix is mostly a UI framework, it is oriented for usage in complex client side apps with a lot of controls and complex business logic. At the same time, it can be effectively used for solving common tasks without the necessity of learning any third party libraries. Let’s check these Webix features by creating a simple “ToDo” app. The ToDo App is like a “Hello World” for frameworks. It is the basic app, which shows how the main functionality of the framework can be used.
You can grab the code of final version from GitHub or check the online demo.
One of the key advantages of the Webix library is the ability to work on both desktop and mobile devices. A web-based user interface created with Webix will work properly on both platforms. Still there are some recommendations which will help you to achieve a better user experience while developing your mobile web app.
In this article I’ll try to describe the most significant features of mobile applications development. Let’s go into details by creating a simple ‘contact list’ app. This is a common app that allows users to create a contact list, look up the necessary contacts and view their details.
You can download the full sources of the actual working application from the github repo or go check a live demo.
