npm testwill quickly give you an upset stomach, so we decided to see what could be done to speed up the process, and ended up with a 95% speed improvement and being able to remove a lot of dependencies to boot. ]]>
However if you do need to send some data to your server at some point, you need to ensure that the users posting to your server, are actually who they say they are. This tutorial will go through the sign in process in a SPA, and validating the access tokens we recieve on our own server. First let's look at how to create a simple sign in page.]]>
This example will be based on a web app I made a while ago, a currency convertion app called Kuranz. The app is using GPS to determine the currency of the country you are in, and it works offline in countries where data roaming is expensive or even impossible.]]>
This is an important tool to protect against cross-site scripting (XSS), clickjacking and other client side attack vectors. XSS can for example be used by evildoers to place a script into your website, replace the login field in your online bank, and send usernames and passwords to somebody else. Another trick could be to load your page in an iframe on a similar domain, so it looks like your page loads normally, all the while evil hackers are snatching up passwords and credit card information.
These techniques can be virtually undetectable to the user, as everything will look normal, and since these attacks happens on the client side, it can be difficult to detect until the damage is done.
That's why you need a Content Security Policy!]]>
If you have an older Mac (2010-2012), you might have some trouble using Boot Camp in MacOS X Yosemite. For some reason Apple does not allow Macs with a SuperDrive to make a bootable USB stick with Windows from an image. Since the optical SuperDrive in my Mac recently quit on me (and because USB is much better), this has lead me around the murky corners of message boards in search for a solution, which I now share with you here.]]>
crontab, which is a scheduling tool that will run jobs (scripts) at regular intervals. ]]>
REST uses the standard HTTP status codes to indicate the success of a request, so we must ensure it returns the expected codes, especially in error scenarios.
I recently implemented a simple REST API in PHP for Regex Crossword, so in this article I will show how to write some API tests using PHPUnit 5.0 and Guzzle 6.1. Actually we can test any API written in any language using this, but if you are used to PHP this will be very easy.]]>
After this tutorial you will have a working local Apache server with PHP, and I will show you how to create sub sites for each of your web projects directly from Dropbox.
This is an updated version of my article on Mavericks, as a few things have changed with OS X Yosemite and the upgraded Apache 2.4.
Update 2015-10-15: This guide will also work with MacOS 10.11 El Capitain.]]>
The good guys at Harp are working on building this into the platform, but until then it's actually very easy to do yourself. You just need npm and to enter a single command in the Terminal.]]>
We'll use the gulp build system to read the image files and output the data we need to a JSON file, which we can then read into Google Maps.]]>
This a quick writeup of how to get a local web development server up and running on your Mac. Everything you need is preinstalled, and just needs to be configured. Some familiarity with the Terminal is presumed (e.g. how to start it).

So you have an object with all the request data that you need to transfer, but now you have to convert this into a query string. There are a lot of ways to do this, but often it becomes a rather manual task concatenating all the properties one by one. Wouldn’t it be easier if you could somehow automatically transform all the properties of your class into a query string?
The good news is, that by using C# reflection and extension methods, you can create a simple solution, which will be extremely easy to use and work well for most types of (POCO) classes.]]>
Ideally I want to give my class properties an abbreviated alias for use in the query string. Thus, I should be able to use the following URI instead, and still have the input values mapped automatically to the model:
Fortunately there is an elegant solution, which I must admit I’m blatantly writing up based on an answer given on Stack Overflow. My solution does however fix a bug to make multiple aliases on a single property work as intended.]]>
Since localization is a basic need for all international applications, I have made a simple structure, which can be applied in situations where an entity is required to have localizable values.]]>
This text will be ignored by Gmail, and you will receive your emails as usual, but it allows you to create unique email addresses on the fly.]]>
As I started implementing my custom MembershipProvider, I became a bit confused, however, about the sheer number of classes you have to implement/override. I ended up spending quite a lot of time searching for help, so here I will attempt to give a “shortcut” overview of the structure of the MembershipProvider model and lessons learned.]]>
