My Microsoft colleagues Burke Holland and Cecil Phillip built a very useful application called 'The Urlist' using a serverless approach with Azure Functions and Cosmos DB. They presented this app in a Build 2019 session and of course they open sourced everything. This is great because then I can learn from it and maybe in return add something new to it. But first I need to get it up-and-running on my own laptop (and Azure subscription). So, let's dive in (head first)! 

If you want to follow along, I highly recommend you read the article I linked to above first. As said, the source code for the application is available at If you open that link in your browser, GitHub will show you the for the project straight away. The readme points to two other links which help you to get the frontend and backend parts of the app running in your local environment. Now, it could be me, but I did not end up with a running application by just following those two readme's. Here's what I changed to get to the up-and-running state:

One of the first things I noticed when I opend the code in Code (by using the .code-workspace file) was that the Vue.js Frontend workspace folder was empty. The fix for this is easy. Just change the line

"path": "Vue.js Frontend"


"name": "Vue.js Frontend",
"path": "frontend"

in the .code-workspace file. There is already a PR submitted for this change.

The second issue I ran into was that the backend code wouldn't compile. It turned out that the SDK that is configured in the global.json file (2.2.105) was not installed on my machine. After changing it to 2.2.300 the code compiled fine.

I then wanted to run the 'SaveBundle' command from Postman (as described in the backend Unfortunately that replied back with a 500 server error. After investigating I found that this was caused by the fact that I had created the database ok through the Azure portal, but it was (of course) still completely empty. The code in SaveLinks.cs did not know where to put the data. To fix this I added the CreateIfNotExists = true attribute to the SaveLinks method in that file. This way the necessary work in the database is automatically done when the structure is not there. After adding this the command ran fine. It's not the best  fix possible I think, because it requires running the Postman part of the readme. Let me know in the comments if you know of a better way to fix this.

After installing only a 'few' npm packages, I fired up the frontend. The site came up and looked exactly like the live version. Succes? Well, not quite yet. I could add links but pulling up the Developer Tools in the browser showed a lot of errors. All were in one way or another related to CORS. The error messages were a bit cryptic but a 'withCredentials' property was mentioned in some of them. I used this for a search through the codebase and found this property (only once)  set to true in the api.service.ts. I set it to false, tried again and all the errors disappeared.

I'll contact Burke and Cecil to see if/how these changes should/can be applied to the main repository. I also have an idea for some new functionality, but I'll leave that for another post.

Hope this helps!

Hi all,

Just checking in after a good month of onboarding @ Microsoft. If there is one thing I learnt this month, it's that there is a lot more to learn...

It is not just about learning Azure. Learning how Microsoft 'works' and understanding about all the different parts that is Microsoft is a study on it's own. That is if you can keep up with all the TLA's (Three Letter Acronym) they keep throwing at you.

Azure is now such a huge platform that it has grown beyond what one person can comprehend and understand. Now it is 'just' a matter of selecting the topics that I need to learn more about. In the next few weeks I'll be taking some exams to test my knowledge level and then the proof will meet the pudding, I guess. The number one tip I received was to just take the exam. That way you'll quickly learn which areas of expertise you're not an expert in yet. I count on having some area's to study on after that.

After a great bootcamp in Remond with about 325 'also new in role's', I'm going to meet my local team this week. If that is done we will start with slowly (and hopefuly softly) introducing me to our local customer teams. The 'real' work starts then and I think I'll be writing about more technical stuff then.
