Microsoft Flow In 10 Days - Day Six - Flow Vs Logic Apps

Now we are going to create a Logic App.

Logic App Creation

To create a new Logic App, type “logic” in the search bar and select “Logic Apps” from the options shown below.

Now click on “Create Logic App” on the next screen.

It opens up a panel sort of thing, where the details are entered for the new logic app. I am selecting my already created resource group here.

Once all are filled, click on Create button.

After a couple of minutes, if you refresh the page, we can see the below.

Click on the Logic App, it navigates to the templates page where we can select an already available trigger. (Same as the MS Flow functionality).

In the above screenshot, we can see, there are some triggers which are not part of the MS Flow (highlighted in Red).

Highlighted in green are the things which are common for MS Flow as well as Logic Apps.

Also, we can start from blank, (scroll down a bit) like how we do in MS Flow. If you need any clarifications, please refer to my previous articles (Links given above).

Click on this to start a new Logic App from Blank.

We get to see a screen that is very similar to the Flow’s screen.

In this, I am going to select SharePoint as the connector.

I am going to pass the address of my site and take “Leave Request” as my list, and I will get a screen like this.

We can see a difference in this when comparing this with MS flow. There will be an additional block “How often do you want to check for items?”

There is certainly a difference between these 2 systems.

So from this what we can infer is, when a new item is created in SharePoint,

I am setting the time frequency for 5 seconds. And when a new item is created, I am sending the mail to the person who created it.

Same as in MS flow, we get the metadata panel on the right side when clicking inside any field.

Now we are going to test it after saving. This will be present at the top of the designer view of this logic app.

Click on Run to test it.

We will get the below screen once we click Run.

Once a new item is created in the list, we see the below notification on the right top corner of the screen.

Also, we can see the first step (item created trigger) has a green tick. Then after a few seconds, we can see both steps are successful and the green tick is on both the steps.

So it has successfully run. So we can say that this is very similar to the MS flow environment with a few differences.

Now how do the developers come into the picture. There is a code view along with this Logic Apps architecture.

Click on the code view and you will see a huge JSON file. You can go through the JSON file and find all the settings we have done on the designer view of this Logic App.

If we do changes in the Code view and save it, it will still be reflecting in our logic app.

We can start from scratch and build a complete logic app in the code view.

Yes!!! This can be done easily using the Visual Studio IDE.

That’s how developers can do this in their own way.

These are some of the key features of Logic apps. Also, we have seen the similarities and differences between the two systems.

I will try to cover more of Azure and its components in another set of articles.
