Email signature web part

This web part allows users to copy their company's branded email signature and paste it into their email client.

This web part is licensed under MIT.

Features

Content authors can add their own HTML template for email signatures.
Web part automatically pulls contact information from Microsoft Graph and fills in the template. This requires permitting the app to User.ReadBasic.All API permissions.
Users can optionally edit all the values.
Custom properties can be added to the web part and be made optionally editable by the user.
Profile photos can be pulled in, and optionally be made round.

Installation

Download the latest .sppkg release.
Go to your SharePoint's tenant app catalog.
Upload the email-signature-web-part-{version}.sppkg package.
Determine whether or not the client-side solution should be made available to all sites in the organization (tenant wide). Note that this solution will require additional permissions and informs you that it will request User.ReadBasic.All from Microsoft Graph.
Click Deploy to deploy the solution.
In the SharePoint admin center, go to the API access page and approve the new Microsoft Graph API access request.
(Optional): If in step #4, the solution was not made tenant wide, go to the site that the web part should be placed on. In the Site Contents, add the new spfx-email-signature-web-part-client-solution app.
Go to a page in your SharePoint site and add the Email signature web part.
Edit the web part properties to add your custom email signature.
Publish the page and test.

Building

This web part is built with the SharePoint Framework (SPFx). It can be cloned and built using the normal SPFx gulp tasks, or by using the following npm scripts:

npm run serve:browser to start a local development server using SharePoint Workbench and mock data.
npm run serve to start a local development server to run against a real SharePoint environment
npm run dist to create a production build and package

Version numbering

Multiple areas of the code base need to be updated when making a version number change. This has been automated in a preversion script, so using npm vesrion is required.

Testing

This web part uses jest and react-testing-library for its tests. Due to limitations with SPFx's react-dom version and react-testing-library, this library has upgraded react and react-dom to 16.9.0.
