Show Suggested Answer Hide Answer
Suggested Answer:
Step 1: Run pac pcf init ג€"namespace ..
This is the first command which creates basic folder structure of PCF control project.
Run the following command to create the control. The format of the control is: pac pcf init ג€"namespace <specify your namespace here> ג€"name <put component name here> ג€"template <component type>
Step 2: Run the npm install command

Install Dependencies -
Once 'init' sets up the basic folder, as a next step install all the PCF control dependencies using 'npm install' command.
Example:

Now at this point, there is nothing we have actually created. However, the solution created contains sample PCF control code.
Step 3: Run the following np run build command
Build PCF Component.
Once you implement the PCF component, build the code for any syntax errors.
Syntax:
npm run build

I agree with igor_luan13's post Answer: Create a project folder. Run pact pcf init. Run the npm install command. The pact pcf init command in question does not include "--run-npm-install". Therefore, "npm install" must be run again.

the install command is included in the init, so you do not need to call it again. rather call the build at the end

No, just tried it, the install command is NOT included in the init. The pac pcf init command explicitly tells you to run npm install right after it runs. Running: `pac pcf init --namespace samplens --name mycontrol --template field` Returns the following: `The Power Apps component framework project was successfully created in 'C:\Users\iamroot\source\repos\test'. Be sure to run 'npm install' or equivalent in this directory to install project dependencies.` ...and indeed the node_modules folder is only created after npm install is explicitly called.

According to the above link 'pac pcf init' command also runs the 'npm install' command ... so the third step should be to build which .i.e. step 3 - 'npm run build'

I think there must be error in the above link. I just tried running the 'pac pcf init' command and it didn't install anything even though I have latest version of pac installed. So igor_luan13's answer is correct

The request is to create the component,not to build. And between create and build there are needed some code implementation. So I am agreeing that the order is 1.Create a project folder 2.Run the pact pcf init 3.Run the npm install command

Agree. The steps are literally described in the link https://docs.microsoft.com/en-us/powerapps/developer/component-framework/create-custom-controls-using-pcf 1. Create folder 2. npm pcf init 3. rpm run build Other combination does not make sense. e.g. npm pcf already runs npm install.

This is correct one. Other reference looks like for Microsoft Power Platform CLI Component. https://docs.microsoft.com/en-us/learn/modules/get-started-component-framework/3-tooling is correct reference for the Power apps component.

The correct three actions to create a Power Apps component (PCF control) are: 1-Create a project folder You need a dedicated workspace for your component. 2-Run the pac pcf init --namespace SampleNamespace --name ControlName --template field command This initializes the PCF control project inside your folder. 3-Run the npm install command This installs all required packages and dependencies for the component.

Read the options carefully, the pac pcf init did not include npm install command like microsoft document. So you have to run npm install manually

in the DOC : https://learn.microsoft.com/en-us/power-apps/developer/component-framework/create-custom-controls-using-pcf you have the pac pcf -init with --run-npm-install at the end. This is missing from the command in the question. 3rd step is npm install

I think problem is that we don't know if MS has updated the correct answer after they indroduced pac init with automatic call of npm install. PL-400 is quiet old now. Do you have any ideas?

I think since running the PAC PCF Init command already creates the project folder there is no need to create a Project Folder by yourself

Yes it does, but the Microsoft docs also mentions to create a new project folder and then navigate to it and run the commands. https://docs.microsoft.com/en-us/powerapps/developer/component-framework/create-custom-controls-using-pcf
