This post is mostly for Googlers, who experience unexpected issues with SharePoint Framework (like I did).
Whether you like it or not, sometimes shit happens.
Usually, I don't use spaces in paths to my projects, however, one day for some reason I decided it was a great idea (probably I was trying to be more creative). And I paid for it.
If you have created a SharePoint Framework project, and the path to that project contains spaces, you are in trouble. gulp serve will work, gulp bundle gulp package-solution will work. However as soon as you upload your app to App Catalog, you will see an app package error:
Invalid SharePoint App package. Error: Part URI is not valid per rules defined in the Open Packaging Conventions specification. More...
Unfortunately, I haven't used Microsoft Flow in production yet. I read docs, I've tried some basic things, I saw a lot of cool presentations around MS Flow and different integration options. From what I saw and tried so far MS Flow is an extremely powerful tool to automate processes. You can do so many cool things (of course if you have enough experience)! I'm just exploring and in this post, I'm going to build a very simple Flow, which updates a SharePoint item based on different conditions. When SharePoint item is created, it will check the item's field and update the same item based on a condition.
Here is our resulting flow:
So you want to build an SPFx webpart which uses MS Graph API through PnPjs. Here is step by step guide on how to do that.
A few months ago I wrote a similar post, however, things were changed, some things were simplified a lot, that’s why this is a revisited guide. Also, I’ve addressed some additional steps here. The source code is available on the official SharePoint/sp-dev-fx-webparts GitHub repository.
- SPFx >= 1.6
- PnPjs >= 1.2.4
1. Scaffold SPFx webpart solution with React
This step is pretty self-explanatory, simply run yo @microsoft/sharepoint, select React, give your webpart a name, do not change other defaults asked by yeoman.
While support of .NET Core for SharePoint CSOM libraries on its own way (still no ETA), you can create a SharePoint add-in with ASP.NET Core 2.1 today. Of course, it adds some inconveniences, but at least you can target the latest version of ASP.NET. I’ve created a sample project at GitHub here so you can easily try it. This post describes how to configure everything to run it.
First of all, a few drawbacks worth mentioning:
- you can’t use F5 experience in Visual Studio for convenient debugging. Instead, you should manually upload your app into a site and attach Visual Studio to running web application.
- you can’t target a project to netcoreapp. Obviously you can’t do it because SharePoint CSOM for .NET Core is not available yet. That’s why you have to retarget your project to .NET Framework instead. Which means that you lose cross platform feature. If that’s essential thing for you, then you should wait for official .NET Core support.
- solution described here only works for SharePoint Online. On-premises is a completely different story and out of the scope of the post

Are you TypeScript developer? I bet you use tslint in all your TypeScript projects! If not – start using it. SharePoint framework has tslint step which validates your code against tslint rules, which is awesome. More and more web developers today also use stylelint. Stylelint can be easily explained in just three words – linter for css/scss. Modern web developer (and of course modern SharePoint developer) has to write a lot of css or scss code. So why don’t we lint css code as well? Checkout increasing interest in stylelint at npmtrends:
SharePoint Framework in current version doesn’t have built-in stylelint support. However we can easily fix it with custom gulp subtask. Let’s do it right away! More...
It’s November and it’s time to review changes in SharePoint REST API in October with help of SharePoint RESE API Explorer. As usual I have to put below caution:
Please note, that all changes are gathered from Targeted tenant. Most likely this changes haven’t been officially introduced yet, use this post as spoilers to potential upcoming features. If you want to use APIs mentioned here, please check corresponding official documentation to make sure they are available.
With REST API explorer you can navigate between different endpoints, explore their structure, methods, classes and parameters. REST API explorer uses _api/$metadata endpoint to get the REST API data, parses it and presents in tree view format. REST API explorer also stores historical $metadata results in Azure storage making it possible to compare $metadata results we have today and month ago. More...
While developing with TypeScript, you might notice that your bundle size becomes bigger despite all minification techniques. Of course, as your code grows, your bundle will also grow. However there is one hint, which might help you and reduce the size of a resulting bundle. The hint works really good for web projects, which use TypeScript together with webpack. It also means, that this hint is applicable to SPFx solutions as well.
The new size of a bundle heavily depends on your TypeScript code, TypeScript features you use and the amount of TypeScript files you have in your solution. For small solutions it might not work, for mid and big ones it definitely works. Anyway you can verify it on your own solution to see the difference. Let’s get started! More...
Finally I found a time and managed to integrate my blog with proper mail newsletter provider. I used to use built-in BlogEngine widget for that purpose, however I received a lot of bot subscribers. That caused me a lot of troubles, because I received tons of emails saying that email was not delivered, I was blocked by spam filter, suspicious activity and so on. Recently I’ve integrated MailChimp into BlogEngine and starting from today you have an option to receive an email notification about new post in my blog.
If you wish to, you can use this direct link, or use “Subscribe to newsletter” widget in the left or just use popup window (once you close it, it will no longer bother you) to enable notifications for your inbox.
This year I again speak at European SharePoint, Office 365 & Azure Conference as known as ESPC (18 edition). It was a real pleasure to speak first time in Dublin last year. There were a lot of remarkable and exciting sessions. This year's conference promises to be even more interesting. Conference team prepared a few simple steps for you to get most out of the conference. Check it out: More...
