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 .

Install the library and required dependencies

npm install jquery

Update the react component

Import the npm translate module in the src\webparts\spfxAzureTranslator\components\SpfxAzureTranslator.tsx also, you have to get the Azure API secret key from Azure to use this service.

import * as React from 'react';
import styles from './SpfxAzureTranslator.module.scss';
import { ISpfxAzureTranslatorProps } from './ISpfxAzureTranslatorProps';
import { ISpfxAzureTranslatorState } from './ISpfxAzureTranslatorState';
import { Stack, IStackProps, IStackStyles } from 'office-ui-fabric-react/lib/Stack';
import { TextField } from 'office-ui-fabric-react/lib/TextField';
import { IDropdownOption, Dropdown } from 'office-ui-fabric-react';
import $ from "jquery";


const stackStyles: Partial<IStackStyles> = { root: { width: 650 } };
const stackTokens = { childrenGap: 50 };
const columnProps: Partial<IStackProps> = {
  tokens: { childrenGap: 15 },
  styles: { root: { width: 300 } },
};
const smallcolumnProps: Partial<IStackProps> = {
  tokens: { childrenGap: 15 },
  styles: { root: { width: 180 } },
};

export default class SpfxAzureTranslator extends React.Component<ISpfxAzureTranslatorProps, ISpfxAzureTranslatorState> {
  constructor(props: ISpfxAzureTranslatorProps, state: ISpfxAzureTranslatorState) {
    super(props);
    this.state = ({ toLanguage: '', content: '', userinput: '', langarr: [] })
    this._getSupportedLangualge();
  }

  private async _getSupportedLangualge() {
    $.get({
      url: 'https://api.cognitive.microsofttranslator.com/languages?api-version=3.0&scope=translation'
    })
      .done((languages: any): void => {
        let droparr: IDropdownOption[] = []
        let langobjs = languages.translation;
        for (var key in langobjs) {
          if (langobjs.hasOwnProperty(key)) {
            droparr.push({ key: key, text: langobjs[key].name })
          }
        }
        this.setState({ langarr: droparr })
      }).fail(function (res) {
        console.log(res);
      });
  }

  private async _translate() {
    $.post({
      url: 'https://ravichandran.cognitiveservices.azure.com/sts/v1.0/issueToken',
      headers: {
        'Ocp-Apim-Subscription-Key': '03e88fd1d1cc403654861c891001e457',
        'Authorization': 'ravichandran.cognitiveservices.azure.com'
      }
    })
      .done((tocken: any): void => {
        $.post({
          url: 'https://api.cognitive.microsofttranslator.com/translate?api-version=3.0&to=' + this.state.toLanguage,
          headers: {
            'Ocp-Apim-Subscription-Key': '03e88fd1d1cc403654861c891001e457',
            'Authorization': 'Bearer ' + tocken,
            'Content-Type': 'application/json'
          },
          data: JSON.stringify([{ "Text": this.state.userinput }])
        })
          .done((result: any): void => {
            console.log(result);
            this.setState({ content: result[0].translations[0].text })
          }).fail(function (res) {
            console.log(res);
          });

      }).fail(function (res) {
        console.log(res);
      });
  }

  public render(): React.ReactElement<ISpfxAzureTranslatorProps> {
    return (
      <div className={styles.spfxAzureTranslator}>
        <Stack horizontal tokens={stackTokens} styles={stackStyles}>
          <Stack {...columnProps}>
            <TextField label="Any language (auto deducted)" multiline autoAdjustHeight onChanged={(newtext) => { this.setState({ userinput: newtext }); this._translate() }} />
          </Stack>
          <Stack {...smallcolumnProps}>
            <Dropdown
              placeholder="Select a language"
              label="Select Language"
              options={this.state.langarr}
              onChanged={(value) => { this.setState({ toLanguage: value.key.toString() }); this._translate() }}
            />
          </Stack>
          <Stack {...columnProps}>
            <label>{this.state.content}</label>
          </Stack>
        </Stack>
      </div>
    );
  }
}

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.

Sharing is caring!

If you have any questions, feel free to let me know in the comments section.
Happy coding!!!
