Display Group Members Using Graph API In SharePoint Framework

In this article, you will see how to display group members using Graph API in SharePoint Framework by performing the following tasks,

Prerequisites
Create SPFx solution
Implement SPFx solution
Deploy the solution
Approve Graph API Permissions
Test the webpart

Display Group members

Group members (current site group ID is considered) are displayed using Fluent UI Persona control.

Prerequisites

Create SPFx solution

Open Node.js command prompt.

Create a new folder.

>md spfx-fluentui-samples

Navigate to the folder.

>cd spfx-fluentui-samples

Execute the following command to create SPFx webpart.

>yo @microsoft/sharepoint

Enter all the required details to create a new solution as shown below.

Yeoman generator will perform scaffolding process and once it is completed, lock down the version of project dependencies by executing the following command.

>npm shrinkwrap

Execute the following command to open the solution in the code editor.

>code .

Implement SPFx solution

Execute the following command to install Microsoft Graph Typings.

> npm install @microsoft/microsoft-graph-types

Folder Structure

Open package-solution.json “config\package-solution.json” file and update the code as shown below.

}
]
},
"paths": {
"zippedPackage": "solution/fluentui-persona.sppkg"
}
}

Create a new folder named as “models” inside src\webparts\personacontrol folder. Create a new file named as IPerson.ts. Open “src\webparts\personaControl\models\IPerson.ts” file and update the code as shown below.

import { Guid } from "@microsoft/sp-core-library";
export interface IPerson {
id: Guid;
displayName: string;
department?: string;
email?: string;
}

Create a new file named as Dictionary.ts under models folder. Open “src\webparts\personaControl\models\Dictionary.ts” file and update the code as shown below.

export interface Dictionary<T> {
[key: string]: T | undefined;
}

Create a new file named as IPersonaControlState.ts under components folder. Open “src\webparts\personaControl\components\IPersonaControlState.ts” file and update the code as shown below.

import { IPerson } from "../models/IPerson";
import { Dictionary } from "../models/Dictionary";
export interface IPersonaControlState {
members: Dictionary<IPerson>;
}

Open props file “src\webparts\personaControl\components\IPersonaControlProps.ts” file and update the code as shown below.

import { MSGraphClient } from '@microsoft/sp-http';
import { Guid } from '@microsoft/sp-core-library';
export interface IPersonaControlProps {
graphHttpClient: MSGraphClient;
groupId: Guid;
}

Open “src\webparts\personaControl\PersonaControlWebPart.ts” file and update the following.

Import modules
Update the OnInit method

Import modules,

import { MSGraphClient } from '@microsoft/sp-http';

Update the OnInit method,

private _graphHttpClient: MSGraphClient;
protected onInit(): Promise<void> {
return new Promise((resolve, reject) => {
this.context.msGraphClientFactory.getClient().then(client => {
this._graphHttpClient = client;
resolve();
}).catch(error => {
console.log(error);
reject(error);
});
});
}

Update the Render method,

public render(): void {
const element: React.ReactElement<IPersonaControlProps> = React.createElement(
PersonaControl,
{
graphHttpClient: this._graphHttpClient,
groupId: this.context.pageContext.site.group.id
}
);
ReactDom.render(element, this.domElement);

Update the React component (src\webparts\personaControl\components\PersonaControl.tsx),

import * as React from 'react';
import styles from './PersonaControl.module.scss';
import { IPersonaControlProps } from './IPersonaControlProps';
import { IPersonaControlState } from './IPersonaControlState';
import { escape } from '@microsoft/sp-lodash-subset';
import { IPerson } from "../models/IPerson";
import { Dictionary } from "../models/Dictionary";
import { Persona, PersonaSize, PersonaPresence } from 'office-ui-fabric-react/lib/Persona';
import { Stack, IStackStyles, IStackTokens } from 'office-ui-fabric-react/lib/Stack';
import { Link } from 'office-ui-fabric-react/lib/Link';
import { Icon } from 'office-ui-fabric-react/lib/Icon';
import { mergeStyles, DefaultPalette } from 'office-ui-fabric-react/lib/Styling';
const iconClass = mergeStyles({
fontSize: 25,
height: 25,
width: 25,
margin: '0 25px',
});
// Styles definition
const stackStyles: IStackStyles = {
root: {
width: 500,
},
};
export default class PersonaControl extends React.Component<IPersonaControlProps, IPersonaControlState> {
constructor(props: IPersonaControlProps, state: IPersonaControlState) {
super(props);
this.state = {
members: undefined
};
}
private async _getMembers(): Promise<Dictionary<IPerson>> {
const endpoint: string = `/groups/${this.props.groupId}/members?$select=id,displayName,department,mail,photo`;
const response: any = await this.props.graphHttpClient.api(endpoint).get();
const graphResponse: any = response.value;
let peopleDictionary: Dictionary<IPerson> = {};
graphResponse.map(user => {
const person: IPerson = {
id: user.id, displayName: user.displayName, department: user.department, email: user.mail
};
peopleDictionary[person.id.toString()] = person;
});
return peopleDictionary;
}
public async componentDidMount(): Promise<void> {
const members: Dictionary<IPerson> = await this._getMembers();
this.setState({
members: members
});
}
public render(): React.ReactElement<IPersonaControlProps> {
let members = [<div>Getting members...</div>];
if (this.state.members) {
let membersArray: IPerson[] = [];
for (let key in this.state.members) {
let value = this.state.members[key];
membersArray.push(value);
}
members = membersArray.map(member => {
return (
<Persona
size={PersonaSize.size40}
text={member.displayName}
secondaryText={member.department}
/>
);
});
}
return (
<Stack>
<span>Members</span>
{members}
</Stack>
);
}
}

Deploy the solution

Execute the following commands to bundle and package the solution.

>gulp bundle --ship

>gulp package-solution --ship

Navigate to tenant app catalog – Example: https://c986.sharepoint.com/sites/appcatalog/SitePages/Home.aspx

Upload the package file (sharepoint\solution\fluentui-persona.sppkg). Click Deploy.

Approve Graph API permission

Navigate to SharePoint Admin center, click API access in the left navigation. Select the permission requested and click Approve.

Test the webpart

Navigate to the SharePoint site and add the app.

Navigate to the page and add the webpart.
