Question details

The user wants to create a reusable React component that can be shared across multiple SharePoint Online web parts within a SharePoint Framework (SPFx) solution.

How to Create a Reusable React Component in SharePoint Framework

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Developing an SPFx project with multiple web parts and needing an architecture to centralize and share common React components.
Observed behavior: Seeking the correct development methodology and official resources for implementing cross-web-part component sharing in SharePoint Online.

Before you start

Ensure you have Node.js and the Yeoman SharePoint generator installed, and verify that your multiple web parts are configured within compatible SPFx versions.

Solution 1Recommended

Use an SPFx Library Component

The official Microsoft approach to sharing code across multiple SPFx web parts is by generating and linking an SPFx Library Component.

Library components provide a way to create independently versioned and deployed code that is shared across your SharePoint web parts. This reduces the overall bundle size and keeps your React components centralized.

Initialize a new Library Component

Open your command prompt and run `yo @microsoft/sharepoint`. When prompted to choose a component type, select 'Library'.

Develop your React component

Build your reusable React components within the new library project and make sure to export them properly in the main index file.

Link the library locally

In your library project folder, run `npm link`. Then, navigate to your target web part project folder and run `npm link <your-library-name>` to consume the shared components during development.

Official Microsoft Support: Because this involves custom SharePoint development rather than built-in UI features, it is highly recommended to post complex architecture or debugging questions in the SharePoint Development section of Microsoft Q&A.

Solution 2

Publish as an NPM Package

If you need to share React components across entirely separate SPFx solutions or decoupled projects, packaging them as an NPM module is the standard Node.js approach.

Streamline Your Project Documentation with WPS Office

While advanced tools like SharePoint Framework require specialized development environments, drafting your project requirements, API documentation, and architecture diagrams shouldn't be complicated. WPS Office provides a free, lightweight, and incredibly fast alternative to Microsoft Office for all your documentation needs.

1. Download the installer: Visit the official WPS website and download the free installation file.
2. Install the software: Run the setup file and follow the on-screen instructions to complete the installation.
3. Start documenting: Launch WPS Office and open your existing Microsoft Office files or start a new project document immediately.

Fully compatible with Microsoft Word, Excel, and PowerPoint formats (.docx, .xlsx, .pptx).Perfect for drafting SPFx architecture documents, developer guidelines, and project timelines.Features a tabbed UI allowing you to switch between documents, spreadsheets, and PDFs in a single window.Extremely lightweight with fast startup times, conserving system resources while you code.

Frequently Asked Questions

Can I use standard open-source React libraries in my SharePoint Framework project?

Yes, SPFx fully supports standard React libraries via NPM. However, to ensure maximum compatibility and performance, it is best practice to align your dependencies with the React version bundled with your specific version of SPFx.

Where is the best place to get help for SharePoint developer issues?

For developer-specific inquiries, the most active and officially supported platform is the SharePoint Development section of Microsoft Q&A, where Microsoft engineers and community experts provide technical assistance.

What is the difference between an SPFx Library Component and an NPM package?

An NPM package requires separate build and publish steps to a registry before it can be consumed. An SPFx Library Component is optimized for the SharePoint ecosystem, allowing multiple web parts in a tenant to share a single deployed version of the code, reducing the overall script payload.
