Offline Web Applications. Abstract HTML 5 contains several features that address the challenge of building Web applications that work while offline. This document highlights these features (SQL, offline application caching APIs as well as online/offline events, status, and the localStorage API) from HTML 5 and provides brief tutorials on how these features might be used to create Web applications that work offline.

" Creating a Web App for Google's Chrome Web Store. With the recent announcement from Google that it was opening its Chrome Web Store to developers, many web developers are suddenly interested in knowing more about the type of apps that the Chrome Store supports. In this tutorial we'll show you how to get started, and how to use HTML, JavaScript and CSS to create a packaged app for the Chrome Web Store. Getting Started The first thing you're going to need is to download and install the latest build of the Google Chrome browser, Developer Channel release.
You can find it here. The main reason you'll need it isn't that other browsers won't support the apps--pretty much any modern browser will support the features that Chrome Store apps will utilize. The reason is that if you want to install apps from the Chrome Store, you have to be using Chrome (and that specific version). The ability to package apps, which are essentially browser-based applications, is one of the key features of the Chrome Web Store.
What Is Included in a Manifest? 5 Tips for Aspiring Web App Developers. So, you're not content with just using the social web; you want to be part of building it, too. As a budding or beginning web app developer, you've got a difficult but rewarding path ahead of you. You have to master (or at least attempt to master) the intricacies of OOP and scripting languages, learn to build web apps the hard way (practice, practice, practice), and network your way into a few job opportunities. You must also decide whether you'd like to work as a solo/consultant/freelancer, a startup employee or founder, or a rank-and-file developer at an established company. Here are a few tips and words of advice that might make your individual path a bit easier and hopefully a bit shorter. We've also compiled a gallery of 140-character tips from veterans at the end of this post. If you've already found success as a front-end web dev, we welcome your suggestions in the comments, as well. 1. 2.

Www.irisa.fr/triskell/publis/2005/Muller05g.pdf. Web application development. Web application development is the process and practice of developing web applications. Risk[edit] Just as with a traditional desktop application, web applications have varying levels of risk. A personal home page is much less risky than, for example, a stock trading web site. For some projects security, software bugs, etc. are major issues. If time to market, or technical complexity is a concern, documentation, test planning, change control, requirements analysis, architectural description and formal design and construction practices can mitigate risk.
Technologies[edit] Lifecycle Model[edit] Time to market, company-growth and requirements churn, three things that are emphasized in web-based business, coincide with the principles of the Agile practices. Testing[edit] Web applications undergo the same unit, integration and system testing as traditional desktop applications. Many types of tests are automatable. Tools[edit] Other tools include various browsers, FTP clients, etc. See also[edit] Web application. A web application or web app is any software that runs in a web browser. It is created in a browser-supported programming language (such as the combination of JavaScript, HTML and CSS) and relies on a web browser to render the application.[1][2][3] History[edit] In earlier computing models, e.g. in client-server, the load for the application was shared between code on the server and code installed on each client locally. In other words, an application had its own client program which served as its user interface and had to be separately installed on each user's personal computer.
An upgrade to the server-side code of the application would typically also require an upgrade to the client-side code installed on each user workstation, adding to the support cost and decreasing productivity. In contrast, web applications use web documents written in a standard format such as HTML and JavaScript, which are supported by a variety of web browsers. Interface[edit] Structure[edit] Business use[edit] Usage share of web browsers. Most used web browser by country as of February 2014 according to StatCounter. The usage share of web browsers is the proportion, often expressed as a percentage, of visitors to a group of websites that use a particular web browser. Web browser usage share varies from region to region as well as through time.
Accuracy[edit] Measuring browser usage in the number of requests (page hits) made by each user agent can be misleading. Overestimation[edit] Not all requests are generated by a user, as a user agent can make requests at regular time intervals without user input. Certain anti-virus products fake their user-agent to appear to be popular browsers. Underestimation[edit] It is also possible to underestimate the usage share by using the number of requests, for example: Differences in measurement[edit] Summary table[edit] The following tables summarize the usage share of browsers for the indicated month.

Marketing.outbrain. Creating a Web App from Scratch - Part 1 of 8: Basic Idea and Design. Today we begin Part 1 of an 8-Part series on building a web application from absolute scratch to a complete product. I am going to kick things off by introducing the idea, and then I will be handling the design, UI, and general front-end stuff. We are going to be going back and forth from here over to my friend Jason Lengstorf's site Copter Labs. Jason will be handling the back-end stuff like application planning and database stuff. At the end of the week, we'll unleash the actual working application for you. It's Easy, Right? What we're going to create is a "list app". First of all, it needs to work and it needs to work well.
Through this whole 8-part series, we are going to create an app that hopefully does all these things pretty well. The Big Idea This "list app" is going to be called Colored Lists. Sketch It Out No need to get fancy right away. Looks like a list to me.

When putting together the main business portion of this site, I wrote an article that outlines the Six Phases of the Web Site Design & Development Process.
As an integral part of my own company web site, the article is slanted to how I personally help clients through the process of creating their own site. Here on the blog, however, I wanted to create a more generalized post. Same basic idea, however this version can be utilized by anyone, regardless of who they hire to design their web site. I hope this helps when considering building your own site! The Web Site Design and Development Process There are numerous steps in the web site design and development process. The exact process will vary slightly from designer to designer, but the basics are the same.
