Fluent UI Message bar in the SharePoint Framework (SPFx) web part

This article provides steps to implement the Fluent UI Message bar in the SharePoint Framework (SPFx) web part, generally a MessageBar is an area at the top of a primary view that displays relevant status information. You can use a MessageBar to tell the user about a situation that does not require their immediate attention and therefore does not need to block other activities.

Create a new web part project

Open power shell and run following comment to create a new web part by running the Yeoman SharePoint Generator

yo @microsoft/sharepoint

When prompted:

Enter the webpart name as your solution name, and then select Enter.
Select Create a subfolder with solution name for where to place the files.
Select Y to allow the solution to be deployed to all sites immediately.
Select N on the question if solution contains unique permissions.
Select WebPart as the client-side component type to be created.

The next set of prompts ask for specific information about your web part:

Enter your web part name, and then select Enter.
Enter your web part description, and then select Enter.
Select React framework as the framework you would like to use, and then select Enter.

Start Visual Studio Code (or your favorite code editor) within the context of the newly created project folder.

cd .\web part name\
code .

Configure the custom properties

Create a new source code file under the src\webparts\<Webpart name>\components\ folder of the solution. Create the new file I<web part name>State.ts and use it to create a TypeScript Interface

export interface ISpfxFluentuiMessagebarState {
  InfoMessage: boolean;
  ErrorMessage:boolean;
  AccessMessage:boolean;
  WarningMessage:boolean;
  SuccessQuestion:boolean;
  WarningQuestion:boolean;
  WarningLongMessage:boolean;
}

Update the tsx file under the components. First, add some import statements to import the types you defined earlier. Notice the import for I<web part name>Props and I<web part name>State. There are also some imports for the PnP components used to render the UI of the PnP React component and pnp sp imports.

import * as React from 'react';
import styles from './SpfxFluentuiMessagebar.module.scss';
import { ISpfxFluentuiMessagebarProps } from './ISpfxFluentuiMessagebarProps';
import { ISpfxFluentuiMessagebarState } from './ISpfxFluentuiMessagebarState';
import {
  MessageBarButton,
  Link,
  Stack,
  MessageBar,
  MessageBarType,
  DefaultButton, PrimaryButton, IStackTokens
} from 'office-ui-fabric-react';
import { autobind } from 'office-ui-fabric-react/lib/Utilities';

Replace this render function with the following code.

public render(): React.ReactElement<ISpfxFluentuiMessagebarProps> {
    return (
      <div className={styles.spfxFluentuiMessagebar}>
        {(this.state.InfoMessage) ? <div><InfoMessage /><br /></div> : ''}
        {(this.state.ErrorMessage) ? <div><ErrorMessage /><br /></div> : ''}
        {(this.state.AccessMessage) ? <div><AccessMessage /><br /></div> : ''}
        {(this.state.WarningMessage) ? <div><WarningMessage /><br /></div> : ''}
        {(this.state.SuccessQuestion) ? <div><SuccessQuestion /><br /></div> : ''}
        {(this.state.WarningQuestion) ? <div><WarningQuestion /><br /></div> : ''}
        {(this.state.WarningLongMessage) ? <div><WarningLongMessage /><br /></div> : ''}
        <br />
        <br />
        <Stack horizontal tokens={stackTokens}>
          <PrimaryButton text="Show Info Message" onClick={() => this._showMessageClicked('InfoMessage')} />
          <PrimaryButton text="Show Error Message" onClick={() => this._showMessageClicked('ErrorMessage')} />
          <PrimaryButton text="Show Access Message" onClick={() => this._showMessageClicked('AccessMessage')} />
        </Stack>
        <br />
        <br />
        <Stack horizontal tokens={stackTokens}>
          <PrimaryButton text="Show Warning Message" onClick={() => this._showMessageClicked('WarningMessage')} />
          <PrimaryButton text="Show Success with Question Message" onClick={() => this._showMessageClicked('SuccessQuestion')} />
          <PrimaryButton text="Show Warning with Question Message" onClick={() => this._showMessageClicked('WarningQuestion')} />
        </Stack>
        <br />
        <br />
        <Stack horizontal tokens={stackTokens}>
          <PrimaryButton text="Show Long Message" onClick={() => this._showMessageClicked('WarningLongMessage')} />
          <PrimaryButton text="Show info message and hide after 5 sec" onClick={this._showandhideMessageClicked} />
          <DefaultButton text="Hide All Message" onClick={this._hideMessageClicked} />
        </Stack>

      </div>
    );
  }

Update the React component type declaration and add a constructor, as shown in the following example.

export default class SpfxFluentuiMessagebar extends React.Component<ISpfxFluentuiMessagebarProps, ISpfxFluentuiMessagebarState> {
  constructor(props: ISpfxFluentuiMessagebarProps, state: ISpfxFluentuiMessagebarState) {
    super(props);
    this.state = ({
      InfoMessage: false,
      ErrorMessage: false,
      AccessMessage: false,
      WarningMessage: false,
      SuccessQuestion: false,
      WarningQuestion: false,
      WarningLongMessage: false,
    })
  }

place the below code inside the react component class, these functions for message bar the events

 @autobind
  private _showMessageClicked(messagetype: string): void {
    if (messagetype == 'InfoMessage')
      this.setState({ InfoMessage: true })
    else if (messagetype == 'ErrorMessage')
      this.setState({ ErrorMessage: true })
    else if (messagetype == 'AccessMessage')
      this.setState({ AccessMessage: true })
    else if (messagetype == 'WarningMessage')
      this.setState({ WarningMessage: true })
    else if (messagetype == 'SuccessQuestion')
      this.setState({ SuccessQuestion: true })
    else if (messagetype == 'WarningQuestion')
      this.setState({ WarningQuestion: true })
    else if (messagetype == 'WarningLongMessage')
      this.setState({ WarningLongMessage: true })
  }

  @autobind
  private _hideMessageClicked(): void {
    this.setState({
      InfoMessage: false, ErrorMessage: false, AccessMessage: false, WarningMessage: false,
      SuccessQuestion: false, WarningQuestion: false, WarningLongMessage: false
    })
  }

  @autobind
  private _showandhideMessageClicked(): void {
    this.setState({ InfoMessage: true })
    setTimeout(function () {
      this.setState({ InfoMessage: false })
    }.bind(this), 5000);
  }

These all have to next to imports, but inside the react component class

const InfoMessage = () => (
  <MessageBar>
    Info/Default MessageBar.
    <Link href="www.bing.com" target="_blank">
      Visit our website.
    </Link>
  </MessageBar>
);
const ErrorMessage = () => (
  <MessageBar
    messageBarType={MessageBarType.error}
    isMultiline={false}
    dismissButtonAriaLabel="Close"
  >
    Error MessageBar with single line, with dismiss button.
    <Link href="www.bing.com" target="_blank">
      Visit our website.
    </Link>
  </MessageBar>
);

const AccessMessage = () => (
  <MessageBar
    messageBarType={MessageBarType.blocked}
    isMultiline={false}
    dismissButtonAriaLabel="Close"
    truncated={true}
    overflowButtonAriaLabel="See more"
  >
    <b>Blocked MessageBar - single line, with dismiss button and truncated text.</b> Truncation is not available if you
    use action buttons or multiline and should be used sparingly. Lorem ipsum dolor sit amet, consectetur adipiscing

Deploy the solution

You’re now ready to build, bundle, package, and deploy the solution.

Run the gulp commands to verify that the solution builds correctly.

gulp build

Use the following command to bundle and package the solution.

gulp bundle --ship
gulp package-solution --ship

Browse to the app catalog of your target tenant and upload the solution package. You can find the solution package under the sharepoint/solution folder of your solution. It is the .sppkg file. After you upload the solution package in the app catalog. you can find and the web part anywhere across the tenant.
