Security note on ASP.NET beta 5

With the release of Visual Studio 2015, Microsoft have included the beta 5 release of ASP.NET 5. This project template does unfortunately come with a drawback in terms of deployment and security due to the default setup with Bower components.

Project comes with a file named .bowerrc which redirects the default bower_modules folder into the wwwroot/lib folder.

That means all the files that are part of the Bower package that you reference in bower.json, will be included in your wwwroot folder during deployment.

If you have a default setup for an ASP.NET Web App on Microsoft Azure, that means that any .php file located within any of the bower components will execute on your server if access by anyone through a web browser.

Additionally there are hundreds of JavaScript (and other) source files (471 in the few default packages that comes with standard web project) and unit tests that are included with some of the bower packages, these are deployed as well by default – unless you filter the files manually. This does expose you to potential Cross-Side-Scripting issues.

Fix for issues

The easiest way to fix the issue is to delete the .bowerrc file, let Bower install components at the root of your web project, which does not make them a part of your deployed assets. Then use the gulpfile.js to do tasks that performs work on copying only those files your project actually need.

Working on an improved ASP.NET 5 template that should be released here in a few days. It will be example of a Single Page Application built on ASP.NET 5, which utilizes only NPM for packages and removes the use of Bower completely.

This issue relates to ASP.NET 5 beta 5, hopefully Microsoft will change the project templates in the future so this won’t be any further issue.

Localization with WinJS 4.0 on the web

Localization is an important aspect of software and it’s important to implement it in the beginning of any new projects. Here I describe how you can easily localize a regular web site or web app built using WinJS 4.0.

If you are building a regular Universal Windows Application with WinJS, you might not need the following instructions. You can follow the same paths for your localized strings, but you need a small extra JavaScript function to enable loading of your strings when your app is running in the browser, and not using the UWP runtime.

How to localize WinJS controls (HTML) explains how to do this for your regular apps. Read that article first, then you’ll learn the basics on how to localize your WinJS app.

What you need to do, is modify the loadResources method in the example above. And if you are running on ASP.NET 5, you need to add a mimetype mapping for the .resjson file type. If you forget to add this, you will receive a HTTP 404 error messages.

localization1

The first thing you need, is to find the language to display. This can be done many ways, and you should probably have some UI that allows users to change their prefered language. It is a good practice to initially use what the user have configured as their default language in the browser.

language

To load the resources, we need to do a HTTP request to retreive the .resjson file. This is done with the loadLocalResources method, that I found here.

The last part is adding the mimetype if you are building an ASP.NET 5 application, do this by adding the following code to your Configure method in the Startup.cs

StaticFileOptions option = new StaticFileOptions();
FileExtensionContentTypeProvider contentTypeProvider = (FileExtensionContentTypeProvider)option.ContentTypeProvider;
contentTypeProvider.Mappings.Add(“.resjson”, “application/json”);
app.UseStaticFiles(option);

Modern Software Development Trends and Practices

The practices and trends for software development is always in a continuous progress of improvement and changes. With the introduction of cloud platforms and providers, new patterns of working have been introduced that greatly improves the developers’ ability to control infrastructure and deployment.

It is now possible for a smaller group of developers, to configure and deploy large data center solutions without any manual installation or configuration of operating systems, virtual machines and services. These system parts are provided through configuration and automated tasks. This greatly increases the time to market, from code changes, to production ready systems.

Being able to quickly reproduce copies of the deployment environment, greatly reduces the historical issues with production configuration being different than development, test and staging environments. With the ability to scale up and down, and creating and destroying whole environments in the cloud, enables individual developer to do full and proper integration testing of their code changes against real-life environments that emulates the production environment fully, reducing surprises when moving new changes into production.

Another big trend is the explosion of platforms and devices for consuming content and using applications. This trend have changed how software is built, where the client apps and front end needs to be more agile and more responsive. Application logic does then naturally move back into the server infrastructure, with reduced logic running and executed on the clients.

This makes it important to build service based solutions, often in the form of APIs that can be consumed by any platform and client. Relying on one specific platform for building client software is no longer viable in the modern workplace, where devices are used from multiple manufactures running a multitude of operating systems.

Moving the majority of application logic back into the servers, will enable the system to be more agile in the client applications.

Rebuilding existing software is a major task, and therefore building the application logic in a service and API pattern, makes the system more resilient for future changes in the client apps that consumers the APIs.

With the introduction of HTML 5, the web technologies have become a better platform for building client applications, and the web technologies are the only platform that scales well across all devices and platforms. Even still, one need to be open and plan for more rapid changes in the client applications that previous in the software history, changes happen quickly and to be on the forefront and give users the best possible experience, the demand for rewriting the client parts of a whole system is higher now than ever before.

Web Game Layout

layoutOne of those things that have been hard to do properly in HTML before, is build UI’s that takes up 100% of the screen. It’s only a few years ago since it required JavaScript and fancy hacks to make it work properly. Now, you can do it easily, with Flexbox.

There are plenty of examples that often end up being more elaborate than what is actually needed, so I built this minimal example which is the layout shell for a top-secret web game I’m working on.

My example runs on Internet Explorer 11, FireFox 35 and Chrome 40. As this is a template for a game, the main area consists of an canvas, but could easily be replaced with a content container for a regular web app or web site.

See the source code here.

There are no vendor-prefix in the CSS code, so this will only work for the latest versions that all comply to the latest CSS and HTML standards. More details on my new game project will be released in my blog in the coming months.

Flickr Downloadr 3

downloadr-large-promoThe day have come for the public availability of Flick Downloadr 3. This is a photo download tool I first released back in 2007, later updated in 2009 to version 2 and now, after many iterations the third release is available.

Back in 2010, I had a prototype built on WPF, it was never released as an update. Next I started working on one built on HTML-technologies and using Adobe Air as the delivery mechanism. Adobe Air embeds the Chrome-runtime. Later I figured using the Chrome Web Store, as this will improve the delivery and cross platform support.

After a lot of work, and constant refactoring and changes, the first public release is now available. You can install it in the Chrome Web Store and check out the product website.

If you continue to read, I’ll explain some of the work that went into the making of Flick Downloadr 3.

How it was made

downloadr-screenshot-01As mentioned, this app went through many rewrites and changes in the technology. This was primarily due to getting to learn new technologies, to gain the experience and knowledge.

The UI itself have evolved, from a completely custom UI to one that is now built on Material Design guidelines by Google.

Some time before the end of 2014, I decided to reduce the amount of functionality to speed up time to market. In doing this, the new version lacks some features that existed in the previous version. I’m planning on adding these features moving forward, but ensuring high quality in the base functionality, I decided to remove all the unnecessary features and focus on simplicity and primary functionality.

One of the biggest changes from version 2 and the early WPF prototype, is the need to secure the API keys with Flickr. It’s virtually impossible to protect secrets in an HTML-based application, while also hard in Windows Forms/WPF, it’s harder in JavaScript.

First iteration of OAuth token service was built on ASP.NET SignalR using Web Sockets, eventually I turned to Node.js, Express and socket.io as a replacement. Luckily there was NPM packages available for some of the Flickr API calls, so the rewrite was not that hard. After a while, I replaced socket.io with regular HTTP REST calls, due to Web Socket limitations on Azure websites.

The service is hosted on Azure website and utilizes DocumentDB for storage, which is very easy to use in Node.js thanks to the NPM package.

Source Code

The app source code is freely available to anyone, to use and learn from. Hosted on GitHub: https://github.com/sondreb/Downloadr

Big thanks to all all the developers who have built open source components used by this app, and thanks to all existing users of my app. Please give feedback and help steer the development in the future!

Packaging Material Design icons

material_iconsGoogle released their Material Design icons a while back, these are available in pre-processed combined SVG files, CSS sprites with PNG, and individual SVG and PNG files for iOS and Web.

These can be installed with bower or npm:

npm install material-design-icons

When building a web app (or website) it’s important to reduce the network requests and traffic, avoiding to much overhead when loading. That’s why you need a way to packaging only those (Material) icons you need.

First you should copy the individual .svg files from the downloaded material-design-icons folder, into your project (e.g. images/icons/svg). As an example, for my Flickr Downloadr project my resulting .svg file is 5 KB, compared to only the svg-sprite-actions.svg that comes at a relatively hefty ~56 KB, If you need icons from different categories, you’ll get a total of ~250 KB.

To process these files, you need the node package named svg-sprite. And if you want to automate using Grunt, you need to get grunt-svg-sprite.

Tip: When you install this package, it compiles using Visual Studio compiler. If you don’t have Visual Studio 2010 installed, you can use the following switch to use another version of Visual Studio, such as 2012 and 2013.

npm install grunt-svg-sprite –save-dev –msvs_version=2013

That command will update your project.json with that dependency and it will ensure that the compilation uses Visual Studio 2013.

Register the grunt task in your gruntfile.js:

grunt.loadNpmTasks(‘grunt-svg-sprite’);

Then create your own configuration:

// Define the configuration for all the tasks
grunt.initConfig({

svgsprite: {
options: {
spritedir: ".",
sprite: "icons",

},
icons: {
src : 'images/icons/svg',
dest : 'images/icons'
},
}

Now you can run this task with this command:

grunt svg-sprite:icons

This will parse the images/icons/svg folder, then generate two files inside the images/icons folder. One named “sprites.svg” and another named “icons.css”.

Include the icons.css in your web project and start to use your icons with the generated classes. The class identifiers is same as filename.

This process will obviously work fine with custom icons that are not part of the Material Design icon package. This makes it easier for you to mix and match SVG icons from different sources and get a nicely generated and minimized SVG and autogenerated CSS.

Text Editor

BracketsHaving a good text editor when you are writing source code is important. With almost two decades of experience with writing code, I have had my share of time with different editors. In these times with modern web apps, we have a different need than before and there is a lot of new players in the game.

In this article I’m only mentioning a few of the many editors I’ve tried throughout the years and in the last few months. Here you can find a list of HTML editors on Wikipedia, and I suggest you look around to find what fits your own needs.

A little background

I have used Visual Studio as my primary text editor for many years, though my favorite web editor of all times must be Homesite 3. It was fast, efficient and powerful. It was originally developed by Allaire Corporation, and acquired by Macromedia in 2001. Version 4 was at the time of release, a bit bloated and slow for the current computers compared to 3, so I relied on version 3 for a long time. Last version of HomeSite was 5.5, released in 2003 by Macromedia.

Macromedia was an amazing company in many ways, some younger developers getting into our industry might never even know that name, as the company was acquired by Adobe in 2009. The same guy that made HomeSite (Nick Bradbury), started building TopStyle when he left Allaire in 1998. TopStyle have a lot of features from Homesite, but it does belong to another age, with outdated and complex UI.

Popular editors

While my primary editor is Visual Studio, as I’m doing a lot of work with Microsoft .NET, for my Node.JS, Web Apps and other needs, I try to work with different editors to see which one is optimal when the requirements for features such as debugging is less. Visual Studio is a fully integrated development environment, it makes sense to have a separate text editor that is faster and more lightweight.

A lot of people use Notepad++ and Sublime Text. I do think those are some of the most widely used editors around. I do love Sublime Text, it’s fast and powerful. Yet there is a new breed of editors, that are built on a completely different foundation than previous editors. That’s the editors of the future, as they are built on the same technology that you build using them.

Modern editors

The new breed of editors is built on the Chrome/Chromium engine and some embed Node.js as well. That means it’s built on the same foundation as the Google Chrome Web Browser.

That means you get the same great developer tools to analyze and debug the editor itself. Additionally the editor is extensible with web technologies, as oppose to proprietary technologies that is used in some of the older editors available.

The first editor I started using actively built on Chrome, was the Atom text editor. It is developed by GitHub, which was a big reason for my to start using it. I have used it for many months already and followed it’s development. It’s a great editor, and I have written a couple of extensions for it.

Biggest issue I have with the Atom text editor, is the fact that it’s built around CoffeeScript and not JavaScript. While it’s fairly easy to learn CoffeeScript, it does increase the barrier to entry for customization and extensions.

So I started looking elsewhere, and I found Brackets text editor, which is developed by Adobe. Which was released in it’s first 1.0 release yesterday.

It is very similar to Atom in many regards, including it’s extensions. Some of the must-have extensions for both Atom and Brackets, is: Git support (built into Atom), File Icons (makes the different files more clearly distinguishable), Stylus (I recently moved to Stylus as my primary CSS pre-processor).

Building extensions to Brackets is very simple. All you need to do is open the extensions folder, available in the Help menu. Inside the “user” folder, you can create a folder for your extension. Within your extension folder, create a “main.js” and you are “done”!

Run Chrome App

My extension for Atom and Brackets is one that enables a run command for your Chrome Apps. This is something that is built into the Chrome Dev Editor by Google, so I wanted to replicate this to make it fast and easy to run a Chrome App while editing. If you want to quickly test your Chrome App on Android phone, I suggest checking out that editor. It relies on the app “Chrome App Developer Tool” that you install on your Android-device and I plan on adding support for this in Brackets using cca.

My new favorite text editor is now Brackets, while it used to be Atom. I suggest you try both!

What are your favorite text editor? Why do you use it and what makes it good? Leave a comment below!

Threshold To The Cloud

Microsoft is working on the new major release of Windows, which will be released some time in 2015 and be named Windows 10. It’s available now in a technology preview. It’s not advisable for regular users to upgrade at this time. This time around, Microsoft will have a single OS that spans across all screens and devices: Phones, Tablet, Laptops, Desktops and big screen TVs (Xbox One).

We are now about to entering what I call, threshold to the cloud.

Full Circle

The following is based upon my own personal experience and memories of my time in the software industry. Memories can play tricks on us, so please remember that as I might not be entirely correct (I did verify the release dates and some other details).

We have now come full circle when it comes to software development. I did some (in my own view) impressive intranet-solutions back in 1999-2001, utilizing HTML features such as hidden iframe and DHTML to make rich web applications. These ran only on Internet Explorer version 5, 5.5 and later 6 that was released in 2001. At which time it had won the browser war and become the most widely used browser. From IE4 there was a very rapid release cycle and lots of “innovations” in terms of features extending the HTML specification. Some of those innovations stuck around, other’s disappeared.

With the growing popularity with Java (released 1996) as a development platform for Client and Server, and that Microsoft was forced to discontinue their own Java VM, Microsoft had to come up with an alternative platform to avoid loosing too many developers from their Windows-platform, and then .NET was born in early 2002 (beta version in 2001).

After IE6, they won the browser war and had +90% market share. That’s when Microsoft abandoned their browser, which effectively have held the World Wide Web back in development for a whole decade. Yes, the effects was a major step backwards for the software development world. The standards work came to a halt, HTML 4.01 was finalized in 1999. It’s now 2014 and HTML5 is in a proposed recommendation state.

Wired wrote about Bill Gates and his strategy letter The Internet Tidal Wave for Microsoft back in 1995:

“Gates proceeded to outline a strategy for Microsoft to not only enter the internet, but to dominate it.” – Wired

Their strategy after -95 was in some terms a great success, with a complete defeat of web browser competitors. It did have negative effects on the company, which have been found guilty in anti-trust cases in Europe. Before -95, they failed to see the importance of Internet.

– Microsoft failed to understand the Internet in 1995.
– Microsoft failed to understand the Web in 2001.
– Will Microsoft get it right the third time? I do think they will!

It took 5 years, 2006, for Microsoft to release Internet Explorer 7. Mozilla had major issues with bloated software, so FireFox was born. It was a long struggle to gain back market share. And eventually Google launched Chrome.

As this graphics show, it took a whole decade for the innovation to start growing in the browser space again.

Race of the giants

From the release of .NET, there was a race between Sun and their Java, and Microsoft with their .NET. This gave us technologies such as Windows Forms, Windows Presentation Foundation and more recently, Silverlight. The race was for the desktop client and the servers. Microsoft won the desktop easily, yet struggled more on the servers. ASP.NET Web Forms was a technology to more easily ease client developers onto the web. It somewhat accomplished that, but also added a lot of bad stuff to the web. At the same time, the open source communities had rapid innovation with projects such as Ruby on Rails. Microsoft responded with ASP.NET MVC released in 2007. Yes, almost as long time for Microsoft to upgrade their web browser as it took for them to truly understand the web development platform.

After the first version of ASP.NET MVC, Microsoft changed. They changed to a cycle of rapid releases, lots of great innovations. Their recent efforts with turning major parts of ASP.NET into the open source space, will help a lot. What’s happening with the next version of Visual Studio and the ASP.NET-platform is amazing and empowering to developers.

Apps comes to town

Apple have had unprecedented success with their App Store. The amount of apps developed and millions of money that app developers have received is amazing. It changed our life’s and it still is. Apps for everything in our lives. Here is a video that illustrates how everything on our desk have now become digital.

The traditional way of searching, finding, downloading and installing software is tiresome and prone to many errors. I have had to fix many computers that have ended up with a lot of malware. Having dedicated app stores for any platform, ensures that the games and apps are tested and verified. With Windows 8, Microsoft added their own digital store into the OS.

At the same time as the Windows 8 announced, it was clear that their software development strategy was about to change. The future was web technologies.

I believe that the strategy behind Windows 8 was a good and correct, but it failed the proper execution. Biggest issue was the separation of desktop and touch. The apps where all full screen, even a utility such as calculator. The market responded negatively, something had to change.

Web Apps

The title on this section is called Web Apps, with this I try to encapsulate all the world of HTML-based apps. Microsoft call them Universal Apps, Google call them Chrome Apps, Mozilla call them Open Web App. One thing for sure, there will continue to be changes in this space. All of these 3 platforms have gone through revisions of naming already, see my blog post Packaged Web Apps.

I’m betting that Web Apps will stick, it’s short and concise. I love it, Web Apps!

And I do realize that the term “Web application” is already widely used for different things, with different meaning to many individuals. I’m still betting on it to win.

Google have had web apps for a while now, enabling developers to build software using web technologies (HTML5) that runs on Windows OS, Mac OS, Chrome OS and Linux OS. That’s right, the old pipe dream of Java, write once run everywhere, was realized with web technologies.

On the threshold

Now we are on the threshold to the cloud, desktop apps, or rather web apps, will now link our computer desktops directly to the cloud. The lines between what is local and what is remote, will blur even more than what it already have. Apps will update automatically, in the same way websites have for years.

I believe we are living in interesting times, as we did more than a decade ago in 2001. The DotCom crash hurt our industry a lot, and one can only speculate if that might be part of the reasons why Microsoft suspended their Internet Explorer efforts. I don’t know the historic details of that tail, other than what has been publicly made available throughout the years.

I have for years pushed web technologies, HTML5, as the future of software development. Now is the time to get serious, go develop web apps.

Universal Apps for Windows devices

Multi-Device Hybrid Apps

Apache Cordova

Chrome Apps

The final proof that we are at the threshold, have a look at my screenshot that shows two versions of the same app running, one Universal App and one Chrome App. Enjoy!

500px

 

One Store to rule them all?

One final thought: Is there room for two app stores on Windows? Will developers be on both platforms?

We have to remember that, even though Windows is the most important platform in regards to market share, developing Universal Apps for Windows devices means that your apps will only run on those devices. I don’t think many developers would want to leave OS X, iOS, Android, Linux and a whole range of other platforms behind.

I believe that web technologies is the answer to this question, it enables developers to make software that more easily can be deployed using different mechanisms and platforms. The code-reuse across Windows Store Apps and Chrome Apps can be immense, if you plan for it and develop with a cross-platform in mind.

Here is another example of Amazon Kindle Reader, one is a Windows App the other is a Chrome App. Take care and be safe!

Microsoft Azure: Secure Site with SSL certificate (revisited)

Back in January 2011 I wrote the first instructions on how to secure your site with SSL certificate on Windows Azure. Since then, both Azure and IIS have been updated, so I’m revising these instructions here.

Learn how you can create the CSR (Certificate Signing Request) for Windows Azure, using Internet Information Services on Windows Server. The CSR is used to generate the proper SSL by any certificate provider. You will know learn how to go through the process of securing your Windows Azure hosts and enable users to access your services over HTTPS.

Create a new Windows Server

As it is now possible to create virtual machines on Windows Azure, you could easily create a new VM on Azure if you don’t have any on-premisses Windows Server.

create-vm

After the machine is provisioned, you can connect using Remote Desktop Client. You will find the public TCP port on the Endpoints page of the virtual machine. Connect to your Windows Server, either on Windows Azure, another provider or on any on-premiss server.

Install Internet Information Management

Choose the Add roles and features option on the Server Manager. Go through the wizard and select the Web Server (IIS) option on the Serve Roles step. Accept the dialog that adds required feature, the IIS Management Console.

configure-server

Certificate Signing Request

First open IIS Manager and navigate to the root element for the web server. Open the Server Certificates by double-clicking on the icon, as seen in the screenshot.

Server-Certificates

On the right you will see the Actions options. Click the Create Certificate Request to start the wizard.

Certificates-Actions

Fill out the fields in the wizard, in the Common name you will out your domain name.

Request-Certificate-1

Next step is choosing the bit length (strength) on the certificate. Choose a minimum of 2048, in this example I have chosen 4096 which is more secure, but require more computation and can be slower on high traffic sites.

Request-Certificate-2

Choose where to store the signed certificate request on your local computer.

Request-Certificate-3

Open the file in a text editor and copy everything. You need this in your application for SSL certificate.

Request-Certificate-4

Copy and paste the signed request to your selected SSL provider. There are many providers available, and there are different processes for verification and different levels of verifications. Make sure you research which type of certificate and verification that fits your requirement.

Installing and exporting SSL certificate

After you have supplied the request to your SSL provider, and have completed the other verification steps, you will receive one or multiple .crt files, often packed in a .zip.

You normally don’t need the extra certificates, such as the CA (Certificate Authority) certificates that are included. These certificates are normally already installed on your server.

Copy the www_domain_com.crt or similar named file to your Windows Server.

Next step is to install the SSL certificate on your local web site in IIS. We will install the certificate and later export it for use on Windows Azure.

Go back to IIS Manager and the Server Certificates window. Below the link we used earlier there is another one named Complete Certificate Request. Click this and complete the wizard. Note that IIS normally looks for files with the .cer extension, so you might have to choose the *.* option in the Open dialog, if your certificate is in the .crt format.

Complete-Certificate-1

It’s OK to install the certificate in the Personal certificate store, you might get permission error if you try another.

Located the installed certificate in the Server Certificates view inside IIS. Right-click on the certificate and choose Export.

Export-Context

Pick a selection to store the .pfx, and enter a password. Make sure it’s a decent quality password, if you ever loose the .PFX you don’t want anyone being able to easily brute force the password. If you loose the PFX and the password, others will have access to the private key of your certificate and can use it to do malicious actions in various manners.

Export-Certificate

 

Important: Keep your PFX file safe and keep it’s password safe. It contains the private keys and shouldn’t be distributed widely.

 

Configure Certificate for Azure Web Role

Next step is to configure web roles in your cloud project within Visual Studio, to use the new certificate. First thing to do on your development machine, is to copy the .pfx file, double-click to open it, choose the store location to be Local Machine, fill out the password you entered earlier. As you already have an exported private key, within the .pfx file, you don’t need to check the Make this key as exportable.

Certificate-Import-Wizard

 

Now you can open your Visual Studio solution with the cloud project. Expand the Roles folder and double-click your Web Role. find the Certificates tab, click Add Certificate. Fill out a identifier name, can be anything, choose the Store Location to be LocalMachine and the Store Name to be My. In the Thumbprint column, click the “…” button to open certificate selection dialog.

Add-Certificate

If you can’t find the certificate in the dialog, experiment with the various stores to see if you can find it. If you are unable to find it, you can manually install it using the Certificate Management Console add-in.

Navigate over to the Endpoints tab and add a new endpoint with HTTPS as the protocol, and select the certificate to be active for that endpoint.

Add-Endpoint

Now you can launch your web project from Visual Studio and the local Azure-emulator will open two instances, one for HTTP and one for HTTPS. Don’t be afraid of the certificate warnings, these are normal. Your certificate are only valid for the production URL that you specified while ordering the certificate. Meaning that you will get a warning if you re-use the certificate for localhost, “dev.domain.com” and other sites. There exists wild-card certificates, which can be *.domain.com and can be used for many purposes. If you are building a big cloud solution, where you want to have custom domains for Azure Storage, etc. then you should apply for a wildcard certificate. Beware though, it comes with a premium price.

Certificate-Warning

Simply choose to skip/ignore/accept the certificate for your localhost debugging and developing needs.

Adding Certificate to Windows Azure hosts

The last and final step before you deploy your updated web role, is to ensure that Azure have a copy of the certificate.

Login to the Azure Management Portal, find your Azure instance, navigate to the Certificates option. Choose the Upload a certificate link and find your .pfx file.

No-Certificate

 

Upload-Certificate

After the process is complete, you can deploy the updated version of your cloud project. Your site should now be fully functional with the ability to run over HTTPS for secure communication.

Conclusions

Securing your services with HTTPS is important to ensure the privacy and safety of your customers and users. Never allow anyone to authenticate their credentials with your site unless it’s with HTTPS. When you don’t use HTTPS, all the information the user enters on your web site can be sniffed and logged by third parties at various steps in the network from the client computer to your hosted server. In many cases, this data travels across multiple country borders.

Installing and configuring HTTPS certificates is sometimes hard, but I hope this walk-through makes you aware of the importance to use it and how quickly and easy you can get up and running with a valid SSL certificate.

If there is any questions, please leave a comment.

Chromeless Chrome App

Here follows a working example on how to build a chromless Chrome App, which replicates the minimize, restore, maximize and close buttons with custom styling. This makes it possible for you to easily build your Chrome App with a totally custom chrome/window.

Introduction

When you start developing Chrome Apps, you’ll quickly discover that the frame/chrome is not native on Windows 8. The frame is completely white, and it doesn’t indicate in any way if a window is active or in the background, other than inactive X (close) button, which changes from red to gray when the window goes into the background.

Here is how the frame looks like, and on a white background, you can’t really see the frame, it blends into the background.

Chrome_window

The next screenshot shows the normal native Windows 8.1 frame/chrome.

Windows_8_1_window

Source Code

The source is very simple and is built using AngularJS. The example app icon is provided by Pixel-Fabric.

Here is a screenshot from the structure and source of the index.html file.

chromeless_source

Here is how the final results looks like.

Chrome_chromeless_window

The code is fairly simple and if you are already looking into Chrome App development, you should feel right at home.

Downloadchromeless.zip.

The source code license is Public Domain (CC0), do whatever you want with it. The icon is obviously free to use, but is copyright by Pixel-Fabric.
