The SharePoint Framework (SPFx) is Microsoft's modern development model for extending SharePoint Online and Microsoft 365. It replaces classic SharePoint farm solutions and allows developers to build web parts, extensions, and applications using modern web technologies (TypeScript, React, Office UI Fabric). SPFx runs in the browser context with controlled API access to SharePoint data, eliminating many security and performance issues plaguing classic SharePoint development.
SharePoint Framework is a page and web part model for SharePoint Online. Developers build web parts in TypeScript/React, package them as reusable components, and deploy to SharePoint app catalogs. Unlike classic SharePoint (C#, farm solutions), SPFx is client-side with limited server-side code. Web parts can access SharePoint data via Microsoft Graph or REST APIs.
SPFx integrates with Microsoft Teams, Outlook, and Viva Connections. Popular with enterprise organizations using Microsoft 365 as their intranet and collaboration platform. Over 15 million organizations use Microsoft 365; SPFx is the standard way enterprises extend it.
SPFx sits in the application layer, complementing Microsoft 365 backend services. It's ideal for organizations standardized on Microsoft 365 and needing custom intranet solutions, dashboards, or integrations with other systems.
Hire SPFx developers when building custom solutions for Microsoft 365 organizations, extending SharePoint Online with intranet features, or creating reusable web parts for enterprise deployment. Common use cases: employee directories, news dashboards, document management interfaces, and integration hubs connecting Microsoft 365 to other business systems.
SPFx is ideal for: enterprises standardized on Microsoft 365, organizations building intranet solutions, companies needing to extend SharePoint without custom server code, and teams already invested in Microsoft ecosystem (Azure, Dynamics 365, Power BI). Companies like Microsoft, Deloitte, and Accenture build SPFx solutions for clients.
Do not hire SPFx developers if you're not using SharePoint Online or Microsoft 365. SPFx only works with modern SharePoint Online; classic on-premises SharePoint requires different solutions. Evaluate whether your business problems are best solved with SharePoint or alternative platforms.
SPFx developers often pair with Microsoft 365 administrators and compliance teams. A typical team includes: SPFx developers building components, M365 admins managing tenant and governance, and business analysts defining requirements. SPFx developers coordinate with security teams on API permissions and data handling.
Must-haves: Deep TypeScript and React knowledge, since SPFx web parts are React components. Understanding of SharePoint REST API and Microsoft Graph queries. Knowledge of SPFx web part lifecycle, properties pane, and communication patterns. Comfort with npm, webpack, and build tooling. Understanding of SharePoint modern page model.
Nice-to-haves: SPFx extensions (command sets, field customizers), adaptive cards for Teams integration, application customizers, search results formatting, and PnP (Patterns and Practices) community tooling knowledge.
Red flags: Claims SPFx expertise but limited React/TypeScript fundamentals. Difficulty explaining SPFx lifecycle vs. React lifecycle. Unfamiliar with Microsoft Graph or REST API concepts. No experience with npm or webpack. Unable to discuss browser console debugging.
Junior (1-2 years): Build simple web parts displaying SharePoint list data. Configure properties panes. Use Office UI Fabric components. Basic TypeScript and React. Understand manifest files and deployment.
Mid-level (3-5 years): Build sophisticated web parts with real-time updates and multiple data sources. Implement web part communication via dynamic data sources. Use Microsoft Graph for advanced queries. Build extensions and command sets. Proper error handling and accessibility.
Senior (5+ years): Architect complex SPFx solutions integrating multiple data sources, Teams, and third-party services. Design reusable component libraries for enterprise deployment. Mentor teams on best practices, governance, and performance optimization. Modernize legacy SharePoint customizations.
Tell me about the most complex SPFx web part you've built. What made it complex and how did you solve it? Listening for: Architectural thinking, problem-solving, data integration understanding. Strong answers mention Microsoft Graph queries or state management.
Describe a time you migrated a classic SharePoint customization to SharePoint Framework. What challenges did you encounter? Listening for: Migration thinking, platform differences, risk management.
Walk me through how you approach building a web part that retrieves data from multiple SharePoint sites and external APIs. Listening for: Data architecture thinking, async handling, error resilience.
Tell me about a time you debugged a complex SPFx issue in production. What was your approach? Listening for: Problem-solving methodology, browser tools, logging discipline.
Describe your approach to testing SPFx web parts. What tools do you use? Listening for: Quality mindset, testing strategies (unit, component, manual).
Explain the SharePoint Framework web part lifecycle. How does it differ from the React component lifecycle? Testing for: Core SPFx understanding. SPFx lifecycle includes constructor, onInit, render, onAfterRender. React lifecycle within SPFx's render.
How would you implement communication between two web parts on the same SharePoint page? Testing for: SPFx component communication. Dynamic data source pattern or localStorage.
Walk through fetching data from Microsoft Graph in an SPFx web part. What permissions are required? Testing for: Microsoft Graph and permission model. MSGraphClientFactory, OAuth scopes, Admin consent.
How do you handle errors gracefully in SPFx web parts? What's the user experience? Testing for: Error handling discipline. Try-catch, error states, user-friendly messages.
Describe how you would optimize an SPFx web part that is slow to load data from SharePoint lists. Testing for: Performance optimization. Pagination, filtering, caching, PnP search for large datasets.
Build an SPFx web part with: (1) Display employee list from SharePoint. (2) Search and filtering by department. (3) Click employee to show details in dialog. (4) Export filtered list to CSV. (5) Cache data for 5 minutes. (6) Handle errors gracefully.
Scoring rubric: Correct web part structure with properties pane. React component rendering. Event handling. Dialog component. CSV export. Caching logic. Error handling with user feedback. Bonus: Pagination, keyboard navigation, accessibility, loading states.
