Transitioning to Powell Intranet in the era of SharePoint add-in retirement

by Matthieu Silbermann

Microsoft’s recent announcement regarding the retirement of SharePoint Add-ins marks a pivotal shift in Intranet development. This comprehensive article delves into the intricacies of SharePoint Add-ins, the implications of Microsoft’s end-of-life announcement, and the technical challenges of migrating to the PnP Framework.

Given the complexity of this migration, Powell Intranet emerges as an even more strategic recommendation, having developed its solution on the future-ready SharePoint Framework (SPFx), offering a seamless, modern intranet experience with less complexity.

1. SharePoint add-ins and SharePoint add-in store: enhanced intranet capabilities

SharePoint add-ins overview:

  • Definition: SharePoint Add-ins are self-contained extensions of SharePoint websites, enabling functionality enhancements without custom server-side code. They are part of a modern SharePoint experience, focusing on secure, easily manageable solutions.
  • Types: There are two main types of SharePoint Add-ins:
    • SharePoint-hosted Add-ins: These are hosted within SharePoint and created using HTML, JavaScript, and CSS. They work within the limitations of SharePoint’s sandbox environment, making them secure but somewhat restricted in capability.
    • Provider-hosted Add-ins: Hosted outside of SharePoint, these add-ins can be developed in any programming language and offer greater flexibility. They can interact with SharePoint data and services but are not limited by SharePoint’s environment.
  • Examples of SharePoint Add-ins for Intranet Enhancement:
    • LiveTiles SharePoint: For custom, interactive intranet page designs.
    • Lanteria HR: integrates HR management into SharePoint.
    • KWizCom SharePoint Calendar Plus: Advanced calendar and event management.
    • ShortPoint: Simplifies intranet design and content structuring.

SharePoint Add-in Store:

    • Function: A marketplace for SharePoint Add-ins where users can discover and install applications to extend the capabilities of their SharePoint environment.
    • Variety: The store hosts many add-ins, from simple UI enhancements to comprehensive business solutions.

2. Microsoft’s shift away from SharePoint add-ins

Microsoft’s recent announcement regarding the end of life for SharePoint Add-ins marks a significant transition in the SharePoint ecosystem. This decision reflects a strategic shift towards newer, more modern extensibility models.

Let’s delve into the details of this announcement and its implications.

Key Announcements by Microsoft:

End-of-Life Dates:

    • For New Tenants: SharePoint Add-Ins will stop functioning for new tenants as of November 1st, 2024.
    • For Existing Tenants: They will stop working and be fully retired for existing tenants by April 2nd, 2026.
    • Public Marketplace Changes:
      • Timeline for Marketplace Changes: From March 1st, 2024, new SharePoint Add-Ins will no longer be accepted for listing in the public marketplace. Starting July 1st, 2024, acquiring SharePoint Add-Ins from the public marketplace will not be possible.
      • Tenant App Catalog Support: Using a tenant app catalog for SharePoint add-ins deployment will remain supported until April 2nd, 2026.

3. migration to SharePoint framework from SharePoint add-ins

Recognizing the evolution of SharePoint development, Microsoft recommends transitioning from SharePoint Add-ins to the SharePoint Framework (SPFx) as the primary migration path. This move aligns with modern web development practices and enhances SharePoint’s capabilities. Let’s delve into the complexities involved in this migration:

3.1 What is SharePoint Framework (SPFx)?

SharePoint Framework (SPFx):

    • Definition: The SharePoint Framework is a page and web part model that fully supports client-side SharePoint development, easy integration with SharePoint data, and support for open-source tooling.
    • Purpose: SPFx is designed for building robust, flexible, and visually engaging web parts and page designs in SharePoint, optimizing the user experience for both mobile and desktop views.

Side Note

Patterns and Practices (PnP) Framework:

    • Definition: The PnP Framework is a code-centric and template-based platform for provisioning your site collections in SharePoint.
    • Purpose: It’s used for persisting and reusing provisioning models across SharePoint environments in Office 365 and on-premises. It provides a way to customize templates and automate the deployment and management of SharePoint components.

Key Differences:

    • Scope: SPFx focuses on the client-side development of web parts and user interfaces in SharePoint, whereas the PnP Framework is geared towards backend provisioning and configuring SharePoint sites.
    • Usage: SPFx is commonly used for creating engaging user experiences, while the PnP Framework is often employed for automating site collection creation and configuration tasks.

3.2 Suggested technical path from Add-in to SPFx

Migrating from SharePoint-hosted add-ins to SPFx involves several technical steps:

    • Transition from SharePoint Add-in Model: SharePoint Add-ins were hosted applications on SharePoint Online, using JSOM for data interactions. SPFx shifts this approach to client-side solutions utilizing REST APIs and Microsoft Graph.
    • Development Environment Setup: A crucial step involves setting up a development environment for SPFx, requiring the installation of necessary tools and frameworks.
    • Creating SPFx Solutions: This step includes creating new SPFx solutions like web parts and leveraging modern technologies like React. It demands proficiency in client-side development practices.
    • Data Retrieval and Display: Utilizing SPFx involves fetching data using SharePoint’s REST endpoints and displaying it effectively, requiring knowledge in asynchronous programming and state management in React.

Transitioning to SPFx represents a significant shift toward modern web development practices within SharePoint and necessitates a strategic approach, considering the required technical expertise and potential resource allocation.
