Using Inline Code on your Azure Logic Apps

Did you ever feel the need to run some pieces of code while building your workflows using Azure Logic Apps, and you quickly realized that you need to use and connect something else with your workflow, such as Azure Functions?

But of course, besides the fact that Azure Functions is amazing to run pieces of code, you still need to create a Function App, store your code in a repo (in case you are working as team, in your company, etc..), build a pipeline to deploy your code, maybe generate some ARM templates to follow the Infrastructure as Code principle, and create/configure your Function App while deploying your code.

So, does it really worth all these steps, to run small pieces of code with simple logic? Probably not.
Fortunately, the Azure Logic Apps' team introduced an action named Inline Code, that enables us to run simple and small pieces of code, using Javascript, inside our Logic Apps' workflows. This action is still in Preview mode, but you should be able to easily use it.


Prerequisites

To start using it, there are some some steps you need to perform.

Once you have all the prerequisites, you can start using the Inline Code action. To use it, it is so simple as opening your Logic App, and on the designer, just add a new action and then select the group Inline Code and then action Execute Javascript Code (preview).

Example

So before wrap up, I want to share with you an example of one of the ways I used this functionality. So, I was using Logic Apps to process some tweets on Twitter, based on keywords and hashtags (in this case using the hashtag #Azure), but as we know, usually tweets contains more hashtags, so I was looking a simple way to extract all hashtags from the tweet text, so then I could process it. In this case, I end-up using Inline Code action, and a simple regular expression (Regex) to extract all hashtags from the tweet text. Follows image below.
