Overview

PnP has provided a control that renders it as a People Picker field, which can be used to select one or more users from a SharePoint site or group. This control is useful to be used in the SPFx web part to get the people information from the users. People Picker control offers various configuration options to support most business needs.

In this article, we will explore the People Picker control from PnP on how to use and configure it in the SPFx web part. We will develop a practical scenario to capture the people's information in the SPFx web part using PnP People Picker Control and store it in a SharePoint list.

Develop SharePoint Framework Web Part

Open a command prompt. Create a directory for the SPFx solution.

md spfx-pnp-people-picker  

Navigate to the above-created directory.

cd spfx-pnp-people-picker  

Run the Yeoman SharePoint Generator to create the solution.

yo @microsoft/sharepoint

The Yeoman generator will present you with the wizard by asking questions about the solution to be created.

Solution to be created

Type of client-side component to create

We can choose to create a client-side web part or an extension. Choose the web part option.

The Yeoman generator will perform a scaffolding process to generate the solution. The scaffolding process will take a significant amount of time.

Once the scaffolding process is completed, lock down the version of project dependencies by running the below command.

npm shrinkwrap  

In the command prompt, type the below command to open the solution in the code editor of your choice.

NPM Packages Used

@pnp/spfx-controls-react (https://sharepoint.github.io/sp-dev-fx-controls-react/)

On the command prompt, run the below command to include the npm package.

npm install @pnp/spfx-controls-react --save  

@pnp/sp (https://www.npmjs.com/package/@pnp/sp)

On the command prompt, run the below command.

npm i @pnp/logging @pnp/common @pnp/odata @pnp/sp --save  

Pass the context from the web part to the React Component

As we need the SharePoint context to work with People Picker, we will have to pass it from our web part to the React component.

Open React component properties at “src\webparts\pnPPeoplePicker\components\IPnPPeoplePickerProps.ts” and add the below properties.

import { WebPartContext } from '@microsoft/sp-webpart-base';
export interface IPnPPeoplePickerProps {
  description: string;
  context: WebPartContext;
}

From our web part (src\webparts\pnPPeoplePicker\PnPPeoplePickerWebPart.ts), pass the context to the React component.

export default class PnPPeoplePickerWebPart extends BaseClientSideWebPart<IPnPPeoplePickerWebPartProps> {
  public render(): void {
    const element: React.ReactElement<IPnPPeoplePickerProps> = React.createElement(
      PnPPeoplePicker,
      {
        description: this.properties.description,
        context: this.context
      }
    );
    ReactDom.render(element, this.domElement);
  }
  ...
}

Code the Web Part

On the command prompt, type the below command to open the solution in the code editor of your choice.

code .  

Open the React component file at “src\webparts\pnPPeoplePicker\components\PnPPeoplePicker.tsx”.

Add below imports.

import { PeoplePicker, PrincipalType } from "@pnp/spfx-controls-react/lib/PeoplePicker";

Use the PeoplePicker control in the render method as follows.

export default class PnPPeoplePicker extends React.Component<IPnPPeoplePickerProps, {}> {
  public render(): React.ReactElement<IPnPPeoplePickerProps> {
    return (
      <div className={styles.pnPPeoplePicker}>
        <div className={styles.container}>
          <div className={styles.row}>
            <div className={styles.column}>
              <span className={styles.title}>Welcome to SharePoint!</span>
              <p className={styles.subTitle}>Customize SharePoint experiences using Web Parts.</p>
              
              <PeoplePicker
                context={this.props.context}
                titleText="People Picker"
                personSelectionLimit={3}
                groupName={""} // Leave this blank in case you want to filter from all users
                showtooltip={true}
                isRequired={true}
                disabled={false}
                ensureUser={true}
                selectedItems={this._getPeoplePickerItems}
                showHiddenInUI={false}
                principalTypes={[PrincipalType.User]}
                resolveDelay={1000} />
            </div>
          </div>
        </div>
      </div>
    );
  }
}

In the PeoplePicker component, set "ensure user property" to true. It will return the local user ID on the current site.

Implement the selectedItems property to get the selected People from the PeoplePicker.

private _getPeoplePickerItems(items: any[]) {
  console.log('Items:', items);
}

Define the State

Let us define the state to store the selected user IDs.

Add file IPnPPeoplePickerState.ts under folder “\src\webparts\pnPPeoplePicker\components\”.

export interface IPnPPeoplePickerState {
  addUsers: string[];
}

Update the React component “\src\webparts\pnPPeoplePicker\components\PnPPeoplePicker.tsx” to use the state.

import * as React from 'react';
import styles from './PnPPeoplePicker.module.scss';
import { IPnPPeoplePickerProps } from './IPnPPeoplePickerProps';
import { IPnPPeoplePickerState } from './IPnPPeoplePickerState';
// @pnp/sp imports
import { sp, Web } from '@pnp/sp';
import { PeoplePicker, PrincipalType } from "@pnp/spfx-controls-react/lib/PeoplePicker";
export default class PnPPeoplePicker extends React.Component<IPnPPeoplePickerProps, IPnPPeoplePickerState> {
  constructor(props: IPnPPeoplePickerProps, state: IPnPPeoplePickerState) {
    super(props);
    this.state = {
      addUsers: []
    };
  }
}

Define the controls

Let us add a button control. With one click of the button, we will add the selected users from People Picker to the SharePoint list.

Open React component PnPPeoplePicker.tsx in folder “src\webparts\pnPPeoplePicker\components\”.

Add the below import for button control.

// Import button component
import { IButtonProps, DefaultButton } from 'office-ui-fabric-react/lib/Button';
import { autobind } from 'office-ui-fabric-react';

Define a button inside the render method.

<DefaultButton
  data-automation-id="addSelectedUsers"
  title="Add Selected Users"
  onClick={this.addSelectedUsers}
>
  Add Selected Users
</DefaultButton>

Implement the supporting methods as below.

@autobind
private addSelectedUsers(): void {
  sp.web.lists.getByTitle("SPFx Users").items.add({
    Title: getGUID(),
    Users: {
      results: this.state.addUsers
    }
  }).then(i => {
    console.log(i);
  });
}

Add Selected Users to SharePoint list

We are adding the selected users to the React component state using the addSelectedUsers method of PeoplePicker PnP control. Now, we will implement a logic to add the selected users from the React state to the actual SharePoint list.

Add the below imports.

// @pnp/sp imports
import { sp } from '@pnp/sp';
import { getGUID } from '@pnp/common';
// Import button component
import { DefaultButton } from 'office-ui-fabric-react/lib/Button';
import { autobind } from 'office-ui-fabric-react';

Add button insider Render method.

<DefaultButton
  data-automation-id="addSelectedUsers"
  title="Add Selected Users"
  onClick={this.addSelectedUsers}
>
  Add Selected Users
</DefaultButton>

Implement the addSelectedUsers method.

@autobind
private addSelectedUsers(): void {
  sp.web.lists.getByTitle("SPFx Users").items.add({
    Title: getGUID(),
    Users: {
      results: this.state.addUsers
    }
  }).then(i => {
    console.log(i);
  });
}

Setup SharePoint List

Set up a SharePoint list (named “SPFx Users”) with the below schema.

Column Type Comments
Title A single line of text Out-of-box title column
Users Person or Group Set "Allow multiple selections" to Yes

Test the PnP People Picker

  1. On the command prompt, type “gulp serve”
  2. Open the SharePoint site.
  3. Navigate to /_layouts/15/workbench.aspx
  4. Locate and add the web part (named PnPPeoplePicker) to the page.
  5. Type in the user names in the people picker.
  6. Click “Add Selected Users”.
    Click add selected users
  7. The selected users should be added to the SharePoint list.

    SPFx users

Summary

In this article, we explored the practical use of People Picker control in the SPFx web part. We configured the PnP People Picker control to capture the information from the user and used the PnP list item operation to add the information to the SharePoint list.
