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

[{"id":"ad8758cf.4b2dc8","type":"tab","label":"Flow 1"},{"id":"9cde778f.2b6da8","type":"inject","z":"ad8758cf.4b2dc8","name":"Inject","topic":"Random","payload":"","payloadType":"str","repeat":"5","crontab":"","once":true,"x":130,"y":60,"wires":[["6957bb9c.750024"]]},{"id":"6957bb9c.750024","type":"random","z":"ad8758cf.4b2dc8","name":"RandomNumber","low":"0","high":"10","inte":"true","x":230,"y":160,"wires":[["7a75e415.76d9bc"]]},{"id":"50cfad1a.719084","type":"debug","z":"ad8758cf.4b2dc8","name":"Message","active":true,"console":"false","complete":"payload","x":680,"y":180,"wires":[]},{"id":"8585c283.624df","type":"template","z":"ad8758cf.4b2dc8","name":"StringTemplate","field":"payload","fieldType":"msg","format":"handlebars","syntax":"mustache","template":"Number {{number}} is a {{numberStatus}} number\n","x":540,"y":60,"wires":[["50cfad1a.719084"]]},{"id":"7a75e415.76d9bc","type":"function","z":"ad8758cf.4b2dc8","name":"Logic","func":"//Get payload of random number\nvar randomNumber = msg.payload;\n\n//Number condition \nif(randomNumber < 5){\n numberStat= \"low\";\n}else{\n numberStat= \"high\";\n}\n\nreturn {\n \"number\": randomNumber, \n \"numberStatus\":numberStat\n};\n","outputs":1,"noerr":0,"x":350,"y":60,"wires":[["8585c283.624df"]]}]

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

Better approach would be consuming exposed REST API (SharePoint OOTB) which allowed up to 2 Gb of file to attached using client side scripts i.e. Angular JS. . Here I have used the “Angular File Upload” which capable of doing more tasks other than basic HTML input file control. By consuming this we can attach multiple files either to the list and etc. You can be found the information on how to include this module to your Angular view in following link. Use package manager command to install the scripts. For bower  -->        bower install angular-file-upload For nugget -->       npm install angular-file-upload It requires file buffer array to POST (save) our attachment via REST API, browsers FileReader API is required to use.

Eliminate Duplicates in Microsoft Flow and Azure Logic Apps

There is no straight forward method or Microsoft Flow action  to eliminate values in a collection like Microsft Excel (as of March 2019). This little hack will help you to eliminate/ remove duplicates and create a collection of unique values. Sample scenario: Need to send daily summarized notification to assigned approved with pending approval items. Sample workflow: Initialize an array Iterate collection of data and append items that are not there in the filtered array Side note: This won't be an option to consider if you too concerned about the performance of the workflow but for the time being its an option to consider.
