NodeRED flow to generate a random number and logic based on that



Scenario



  • NodeRED flow to generate a random number between 0 and 10
  • Number generation start without user interaction and generated every 10 seconds
  • Generate condition for log to debug based on generated value
    • Message should be "Number <the generated random number> is a <Number status> number"
    • Logic : if number is less than 5 then <the generated random number> = "low" else it should be "high"




 

Sample code

Turn off/ Hide Details panel/ Information Panel on modern SharePoint lists

Not always we require to show changes done by other which is a mandatory feature in SharePoint online.  What is details pane (aka. Information Pane)? Detail pane/ Information shows information regarding the document if you selected a one or its showing recent changes within a list or library. Follow link to Microsoft documentation about details pane. Bad news: Until Microsoft listen to User Voice , there is no straightforward way to enable disable this even you don't want. Good news: We could write a SharePoint framework extension to hack styles until Microsoft give us a permanent solution. How? I found this sample project (Inject CSS into modern SharePoint pages with React) which could reuse to our purpose. Thanks to Hugo for saving my time.  Steps to awesomeness:  Clone the project Resolve dependencies >  npm i Bundle >  gulp bundle --ship Package >  gulp package-solution --ship Upload package into SharePoint App catalog
