Power Automate Tip: How to define constants without having too many variabled declared

 



I have been architecting things and came to my observation that developers are using too many of the variables in the flow which they want to keep the hard-coded values or technically say constants. Declaring/initializing too many variables makes the flow very big and becomes hard to understand. Moreover, it takes a lot of time and effort to add the number of variable components and to name and add comments. This tip will save you from all of these.


So for a quick tip on how we can declare the constants more effectively so that we are not filling the whole screen with the variable declaration

So to do it we can make use of 2 connectors

  1. Compose
  2. Parse JSON

For example, if you want to hardcode the Site URL and some of the list Names we can do something like this...

Step 1: Compose




Step 2: Parse JSON




Step 3: Usage




Conclusion


So these 2 steps will save a lot of your time and effort which you spent in adding the variable connector and defining them. If you want to update any property at any point in time you can also do that using the expression.


Happy Coding..!!

    Just curious - is there some benefit of using the compose action, over putting the JSON directly into the Content field for the Parse JSON action?

      Hi, there is not much benefit of it.. you can skip.. it is added for explanation and simplification of the flow. By adding that others can understand what JSON is expected

Rename Folder using Microsoft Flow / Power Automate in a Document Library in SharePoint Online

Image
Hi Friends, Today blog is about renaming the folder in the document library using the MS FLOW or MS Power Automate. When I started working on this it seems to be an easy job, but if you look into the connectors you'll find it really difficult as there is no straight forwards connector to do the job. Issues encountered If you try using the " Get Folder Metadata " connector, you'll not be able to get the ID of the folder as it is returning as the negative value. If you get the ID somehow and try to update the folder name using the " Update File Properties " connector, you'll end up renaming only the title of the folder, but it will still have the old name as the display name which in case is again a failure. There is no other connector which can be utilized to achieve the task of renaming the folder in a document library directly. Solution The solution is a simple three-step (at least in this example). Step 1: Initialize variables In case you are computing...
