How to execute Javascript code with dependencies from Azure Logic App?

Vivek Komarla Bhaskar 956

Hi,

When I attempt to execute a Java script code for an authentication token using Logic app, I encounter an issue when I have to pass dependencies. Below is a screenshot showing how to retrieve a token, I already have an integration account. In addition, I have the username and password to access the API, but I cannot get the required token, since I am unable to pass the dependencies.

Hi Vivek Komarla Bhaskar,

Thank you for reaching out on Microsoft Q&A!

As of yet it is not possible to load any dependencies in your Logic App to support external libraries. The only possibility is to create an Azure Function holding all JS code and libraries, and call it from a Logic App.

Please leave feedback for the Logic App team to request support for this in the future:

Hi, @Sonny Gillissen I don't see Javascript in the dropdown of the Runtime stack when creating an Azure function app. Do I need to choose Java?

Hi ,

Sorry, I haven’t been clear. You can select Node.JS to support Javascript. Please refer to the image and doc below:

Thanks, @Sonny Gillissen I created a function app and a function within this function app and also I have uploaded below JSON files (jwt.js & package.json) as mentioned in the screenshot. Now how do I achieve the below requirement?

run npm i to fetch the dependencies declared in package.json

and then run node jwt.js to obtain your JWT token:

You can review this good tutorial for adding the packages:

https://learn.microsoft.com/en-us/shows/beginners-series-to-serverless/install-node-modules-in-your-azure-functions-application-8-of-16--beginners-series-to-serverless

Next, one of your functions would behold the contents of the jwt.js, making it part of your code solution (instead of calling it as a separate file.
