Environment Setup for Power Apps Component Framework (PCF)

Below are the steps to Setup the environment to create PCF Code Components. You will be creating your first pcf code component.

System Setting when developing this component:

  • Machine OS: Windows 10
  • System Type: 64-bit OS
  • IDE: Visual Studio Code

Below are the steps to setup the environment. This is the one time setup and don’t need to repeat this again.

  • Install NPM:

NPM is Node Package Manager. npm is world’s largest Software Library. This is free to use. It includes CLI developers can use to download and install software. npm is installed with Node.js, which means we have to install NodeJS first.

Navigate to Install the LTS version even if it is older then the latest version. The version keeps on changing. I will be using NodeJS version 18.13.0

Click on the LTS version. This will download the node-v18.13.0-x64.msi installer. Click on it and it will open the Installation wizard. The wizard is pretty straight forward. Click Next and install NodeJS. This installation will take a couple of minutes.

  • Install Power Apps CLI (Command Line Interface)

Click here to install Power Apps CLI. This will download .msi file. For me it downloaded powerapps-cli-1.0.msi. Click it and install CLI. It is a simple wizard, follow it and install it.

  • Install Visual Studio Code

I will be using Visual Studio Code for development purpose. It is free of code and you do not need a license for it. Download Visual Studio Code from here.

  • Power Platform Extension

Once you install Visual Studio Code, install Power Platform Extension. Open Visual Studio Code, go to Extensions, type Power Platform Tools. If you see 2 results of the same name, choose the one which is not in Preview mode. Preview Mode releases you can use for development/testing purpose, but they should not be used in Production. Click on Install. This will install the extension.

Extract only Date from DateTime value


We have a datetime column DueDate in a SQL table. I need to display only date version in a label in Power Apps Gallery. Below is the code:


This will return 11-Jan-2023

PCF Code Component Life Cycle

When we develop code component, we implement StandardControl interface and its methods. These methods helps hosting runtime to manage life cycle of code component.

Below are the methods that needs to be used when creating a code component:

PCF Architecture

  • We use HTML, CSS and TypeScript to create code components.
  • Developers can also use ReactJS, AngularJS, Fluent UI. These are optional, but are preferred.
  • 3 areas in code component: Manifest File, Component Implementation and Resource Files.
  • Manifest File has properties about the component like Name, Description, Version, Resource Files etc. App Makers can statically set the value of these properties or dynamically bind it to any available data columns of the application. These properties help the application and component to communicate with each other.
  • Component Implementation has the code files like TypeScript/JavaScript files, User Interface details, functionality, business logic etc. This code file implements StandardControl interface.
  • Resource Files has static resources like libraries used, CSS files, Images used at various places etc.

Create New Environment

Whenever a user signs up for Power Apps or Dynamics, a new environment is automatically created. This environment will be the default environment.

Below are the steps to create a new environment:

Compare two Strings without matching case

Below is the code I used to compare string values from two Text Inputs. This will not compare the case.

That is, “Apple” will be equal to “apple”.

         StartsWith(TextBox1.Text, TextBox2.Text),
         "values matched", "Values did not matched"  

Search for multiple fields in Combo Box

By default, we can display only one field in Combo Box and Search for only one field in Combo Box.

There is a requirement to display multiple fields and also search for multiple fields in Combo Box. For example, we have EmployeeDetails as the Data should display Employee Name and Employee Email ID and can also search the record using same.

Modify below parameters of ComboBox:

Items: EmployeeDetails
DisplayFields: ["EmployeeName","EmployeeEmailID"]
SearchFields: ["EmployeeName","EmployeeEmailID"] 

We can use this for ID and Definition Column types as well.

People Picker in Canvas Apps

Insert a People Picker in Canvas Power App using Combo Box. Below are the steps: Add Office 365 Users Data Source. Add a Combo Box. Click on Edit Fields on Properties Bar. Select Person as the Layout. To pre-populate the Combo Box with the existing value, write below code in DefaultSelectedItems property. RequestSubmittedByEmail and RequestSubmittedByName […]

Check if a Table in Data Source is empty

To check whether a table in data source is empty or not, use IsEmpty


This is equivalent to CountRows(tableName)=0

We cannot use CountRows() directly on data source as it generally gives Delegation warning (Depends on the Connector)

If IsEmpty(tableName) returns true, this indicates that your Data Source table has no rows.
