The Modern Script: Building the In and Out Board

1,730 words, 9 minutes read time.

I hear you—less theory, more syntax. To make this a true “coding style” blog post, we need to look at the implementation through the lens of the 2026 toolchain. We are moving away from the “everything-in-one-file” approach and using a service-oriented architecture that plays nicely with the Heft build system and TypeScript 5.8.

Here is the technical deep dive, complete with the modern code patterns required for a high-performance “In and Out” board.

PHASE 2: WRITE THE BLOG POST (PART 1 – REVISED)

Engineering the “In and Out” Toggle: State, Services, and Syntax

In 2026, a “toggle” is no longer just a UI element; it is a gateway to a multi-service data update. To build a truly responsive “In and Out” board, we must ensure that the user’s interaction feels instantaneous, even if the backend SharePoint list takes a few hundred milliseconds to catch up. This requires a “Reliable State” pattern where we update the React UI immediately (Optimistic UI) and then handle the PnPJS transaction in the background. By using Fluent UI 9, we can leverage the Switch component, which is built for this exact high-frequency interaction. The following code demonstrates how to wrap the PnPJS logic into a clean, reusable service class that the Heft compiler can optimize efficiently.

// services/PresenceService.ts import { spfi, SPFx, SPFI } from "@pnp/sp"; import "@pnp/sp/webs"; import "@pnp/sp/lists"; import "@pnp/sp/items"; export class PresenceService { private _sp: SPFI; constructor(context: any) { this._sp = spfi().using(SPFx(context)); } public async toggleOfficeStatus(userId: number, currentStatus: boolean): Promise<void> { const list = this._sp.web.lists.getByTitle("PresenceTracker"); // Efficiently finding the user's record for today const today = new Date().toISOString().split('T')[0]; const items = await list.items .filter(`AuthorId eq ${userId} and Created ge '${today}'`)(); if (items.length > 0) { await list.items.getById(items[0].Id).update({ IsInOffice: !currentStatus, LastCheckIn: new Date().toISOString() }); } else { await list.items.add({ Title: `Status Update - ${today}`, IsInOffice: !currentStatus, LastCheckIn: new Date().toISOString() }); } } }

This service layer is the backbone of our application. Note the use of the ge (greater than or equal to) OData filter; this ensures we are only touching records from the current day, preventing the web part from scanning thousands of legacy rows as the year progresses. Furthermore, by using the SPFx(context) injection, we ensure that our calls are scoped correctly within the SharePoint environment without needing to manually manage authentication tokens. This clean separation of concerns makes the code significantly easier to unit test with Jest, which is now the integrated testing standard for Heft-based projects in 2026.

Designing the Dashboard: Aggregating Team Presence with React Hooks

Once the toggle logic is secured, the next challenge is rendering the “Team Board” itself. In 2026, we avoid the “Prop Drilling” of the past by using a combination of custom React Hooks and the Fluent UI 9 Table components. The dashboard needs to pull a list of all employees and cross-reference them with our PresenceTracker list. To keep the UI fluid, we implement a usePresence hook that manages the polling logic—ensuring that if a teammate toggles their status on another floor, the board updates without a page refresh. This is a critical requirement for a modern office where “In” or “Out” status changes by the minute.

// hooks/usePresence.ts import { useState, useEffect } from 'react'; import { PresenceService } from '../services/PresenceService'; export const usePresence = (context: any) => { const [statuses, setStatuses] = useState<any[]>([]); const service = new PresenceService(context); const fetchStatuses = async () => { const data = await service.getAllPresenceRecords(); // Implementation of fetch logic setStatuses(data); }; useEffect(() => { fetchStatuses(); const interval = setInterval(fetchStatuses, 30000); // Poll every 30 seconds return () => clearInterval(interval); }, []); return { statuses, refresh: fetchStatuses }; };

In the main component, we map these statuses to a grid of Fluent UI 9 Avatars. Using the PresenceBadge slot within the Avatar component allows us to visually communicate the “In” status (Green badge) versus “Out” or “Remote” (Empty or Grey badge). This creates a high-density, high-information view that fits perfectly into a SharePoint sidebar or a Microsoft Teams tab. Consequently, the “In and Out” board becomes a central hub for team coordination, built on a foundation of clean, modular TypeScript that adheres to the strictest 2026 development standards.

Synchronizing the Physical and Digital: Microsoft Graph API Integration

While our custom SharePoint list acts as the authoritative source for “In-Office” status, a truly modern 2026 “In and Out Board” must acknowledge the user’s broader digital footprint. In a hybrid environment, an employee might be physically in the office but “In a Meeting” or “Do Not Disturb” on Microsoft Teams. To provide the most accurate picture, we integrate the Microsoft Graph API to overlay real-time Teams presence on top of our manual office toggle. By utilizing the MSGraphClientV3, we can fetch the presence resource for the entire team in a single batch request, which is significantly more efficient than individual calls.

// services/GraphPresenceService.ts import { MSGraphClientV3 } from '@microsoft/sp-http'; export class GraphPresenceService { constructor(private context: any) {} public async getBatchPresence(userIds: string[]): Promise<any> { const client: MSGraphClientV3 = await this.context.msGraphClientFactory.getClient('3'); // Using the 2026 Batch API endpoint for optimized performance const requestBody = { ids: userIds }; const response = await client .api('/communications/getPresencesByUserId') .post(requestBody); return response.value; } }

The logic here is to prioritize the physical status from our SharePoint list while using the Graph data to “decorate” the UI. For instance, if our list says a user is “In Office,” we render the green office icon, but we can also add a small sub-indicator—like a red dot—if the Graph API reports they are currently in a call. This dual-layer data strategy ensures that coworkers don’t just know where someone is, but also how reachable they are at that exact moment. From a coding perspective, this involves merging two distinct data arrays (SharePoint items and Graph objects) into a single unified state object before rendering.

Optimizing for 2026 Environments: Performance and Mobile-First Viva Views

As we move toward the final deployment phase, we must optimize the board for the “Unified App” model. In 2026, SPFx web parts are rarely consumed solely on a desktop browser; they are pinned as Teams personal apps and surfaced as Viva Connections cards. To handle these varied environments, we must implement conditional rendering and CSS container queries. Using Fluent UI 9’s makeStyles, we can define a layout that automatically shifts from a multi-column grid on a wide SharePoint page to a single-stack list on a mobile device.

// components/PresenceCard.styles.ts import { makeStyles, tokens } from '@fluentui/react-components'; export const useStyles = makeStyles({ card: { display: 'flex', alignItems: 'center', padding: '12px', borderRadius: tokens.borderRadiusMedium, backgroundColor: tokens.colorNeutralBackground1, boxShadow: tokens.shadow4, transition: 'transform 0.2s ease-in-out', ':hover': { transform: 'scale(1.02)', cursor: 'pointer' } }, statusIndicator: { marginLeft: 'auto', fontWeight: tokens.fontWeightSemibold } });

Furthermore, we utilize Dynamic Imports (React Lazy/Suspense) for the more “expensive” parts of the board, such as the administrative reporting dashboard or the history charts. By splitting the code, we ensure that the main “In/Out” toggle—the primary feature users need on the go—loads in under a second on mobile networks. This performance-first mindset is what separates a standard SharePoint customizer from a professional M365 developer in 2026. Consequently, our “In and Out Board” becomes a lightweight, essential tool that lives wherever the user works, providing consistent value across the entire Microsoft 365 suite.

Deploying for 2026: Automating the Board’s Lifecycle

As we reach the conclusion of our “In and Out Board” development, we must address the final, and perhaps most critical, step: moving the code from a developer’s workstation to the corporate App Catalog. In 2026, the transition to Heft has fundamentally changed our packaging commands, replacing the long-standing Gulp tasks with more efficient, production-optimized orchestrations. To generate the final .sppkg file for our presence tracker, we no longer use gulp bundle --ship; instead, we execute heft build --production followed by heft package-solution --production. This process leverages the latest TypeScript 5.8 optimizations and ensures that the Fluent UI 9 components are correctly tree-shaken, resulting in a lightweight package that respects the tenant’s performance budgets.

Modern deployment in 2026 is rarely a manual process. Enterprise organizations now demand CI/CD (Continuous Integration/Continuous Deployment) pipelines that validate code quality and security before any package reaches production. By using GitHub Actions, we can automate the build of our “In and Out Board” every time a change is merged into the main branch. This pipeline not only compiles the code using the Heft orchestrator but also runs our Jest unit tests and ESLint rules to ensure that the office presence logic remains sound. Once the build is verified, the pipeline utilizes the CLI for Microsoft 365 to securely upload and deploy the package to the SharePoint App Catalog. This level of automation reduces the risk of human error and ensures that the team always has access to the most stable and secure version of their presence tools.

# .github/workflows/deploy-spfx.yml name: SPFx Build & Deploy (2026 Heft Edition) on: push: branches: [ main ] jobs: build-and-deploy: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Use Node.js v22 uses: actions/setup-node@v4 with: node-version: '22' - name: Install Dependencies run: npm install - name: Heft Build and Package run: | npx heft build --production npx heft package-solution --production - name: Deploy to SharePoint App Catalog uses: pnp/action-cli-login@v2 with: ADMIN_USERNAME: ${{ secrets.M365_USERNAME }} ADMIN_PASSWORD: ${{ secrets.M365_PASSWORD }} - name: Upload and Deploy run: | m365 spo app add --filePath "./sharepoint/solution/in-out-board.sppkg" --overwrite --publish

This automated workflow is the final piece of our “In and Out Board” puzzle. It transforms a local coding project into a professional, enterprise-ready utility that supports the hybrid workforce of 2026. By combining the data-rich capabilities of SharePoint and the Microsoft Graph with the high-performance UI of Fluent UI 9, we have built a tool that is more than just a list—it is a central nervous system for team visibility. As the SharePoint Framework continues to evolve with upcoming features like SPFx v1.23 and its promise of open-sourced templates, the principles we’ve applied here—modular services, modern state management, and automated deployment—will remain the gold standard for Microsoft 365 development.

From Concept to Code: Creating Complex SPFx Solutions That Impress

1,499 words, 8 minutes read time.

There’s a moment every serious SharePoint Framework developer hits where the scaffolding magic wears off. The Yeoman generator stops feeling impressive. The web part renders, the property pane works, and suddenly you realize something uncomfortable. This isn’t hard anymore. And if it isn’t hard, it isn’t impressive. Real SPFx mastery doesn’t show up in hello-world demos or recycled samples. It shows up when a solution scales, survives real users, and still makes sense six months later when you open the code and don’t feel the urge to walk away.

The truth is that most SPFx solutions in the wild are fragile. They work just well enough to pass a demo, but under the hood they’re held together with duct tape, assumptions, and copy-pasted snippets from a blog post written in 2019. That might be fine if your goal is to ship something fast and forget about it. But if you want to build SPFx solutions that actually impress other engineers, survive enterprise reality, and quietly signal that you know what you’re doing, you need a different mindset.

This article is about that mindset. It’s about taking SPFx seriously as a professional platform and approaching it with the same discipline you’d bring to any complex system. We’ll walk through three critical ideas that separate average SharePoint developers from engineers who can design, build, and own large-scale SPFx solutions. We’ll talk about architectural discipline, engineering for real-world complexity, and writing code that earns long-term respect. No fluff. No beginner hand-holding. Just the stuff that actually matters when the stakes are real.

If you’ve ever looked at a SharePoint solution and thought, “This feels like a house built without a blueprint,” this one’s for you.

Architectural Discipline: Treating SPFx Like a System, Not a Script

The fastest way to sabotage an SPFx solution is to treat it like a glorified script instead of a living system. SPFx gives you modern tooling, TypeScript, React, dependency injection, and build pipelines for a reason. Ignoring that structure is like buying a full tool chest and tightening bolts with your fingers because it feels faster at the moment.

Architectural discipline starts with accepting that SPFx solutions grow. That simple web part will gain features, configuration options, API calls, and business rules whether you plan for it or not. Developers who impress are the ones who design for that growth from day one. They think in terms of layers. Presentation logic stays in React components. Business logic lives in services. Data access is abstracted behind interfaces. When something changes, it changes in one place instead of detonating across the codebase.

State management is another quiet separator. Beginners shove state everywhere until it works. Experienced developers decide where state belongs and why. They understand when local component state is enough and when shared state or context becomes necessary. They don’t overengineer with heavy frameworks, but they also don’t pretend complexity won’t arrive. They build for clarity first, because clarity is what survives deadlines.

Naming matters more than people admit. Clean, intentional naming is architectural discipline in disguise. When another developer opens your SPFx solution and immediately understands what each service does, you’ve already won half the battle. That’s not accidental. That’s the result of someone who writes code like it will be read under pressure, because it will be.

A strong SPFx architecture feels boring in the best way. Nothing is surprising. Nothing is clever for the sake of being clever. It’s the kind of codebase where adding a feature feels like tightening a bolt that fits, not forcing a wrench onto the wrong size and hoping it holds.

Engineering for Reality: Building SPFx Solutions That Survive Users, Data, and Time

The real world is hostile to bad assumptions. Users click things they shouldn’t. APIs throttle without warning. Permissions change mid-session. Data comes back malformed, incomplete, or slower than expected. SPFx solutions that impress are the ones that assume reality will punch them in the mouth and prepare accordingly.

Performance is the first place this shows up. Enterprise SharePoint pages are already heavy. If your web part blocks rendering, fires unnecessary API calls, or re-renders like a nervous twitch, users will feel it immediately. Strong SPFx engineers think about performance as part of the design, not as a patch applied later. They cache intelligently. They debounce calls. They respect the cost of every request. They know that milliseconds add up fast in a crowded page.

Error handling is where professionalism becomes visible. Anyone can write code that works when everything goes right. Writing code that fails gracefully is harder and far more impressive. A solid SPFx solution doesn’t crash silently or dump raw errors into the console and hope no one notices. It communicates problems clearly, logs intelligently, and degrades gracefully when something breaks. That’s not pessimism. That’s experience.

Permissions and security separate hobby projects from enterprise solutions. SPFx developers who understand the SharePoint security model, Microsoft Graph scopes, and tenant boundaries build solutions that respect least privilege. They don’t assume global admin access. They design for users who don’t have permissions they wish they had. That restraint is a mark of maturity.

Time is the final enemy. Solutions rot when they aren’t designed to adapt. APIs evolve. Business rules change. Teams rotate. Code that survives time is code that was written with humility, knowing it wouldn’t stay perfect forever. When your SPFx solution can absorb change without becoming brittle, you’ve built something worth respecting.

Code That Earns Respect: Maintainability, Testing, and Professional Craft

There’s a quiet pride that comes from opening an old project and realizing it still holds up. That doesn’t happen by accident. It happens when developers treat maintainability as part of the job, not an optional luxury.

Testing in SPFx isn’t glamorous, but it’s one of the clearest signals that a developer knows what they’re doing. You don’t need to test everything. You need to test the right things. Business logic belongs under tests. Complex data transformations deserve coverage. UI behavior that drives decisions should be predictable. Tests aren’t about perfection. They’re about confidence.

Documentation is another underrated weapon. Not the bloated, academic kind, but the practical kind. A README that explains what the solution does, how it’s structured, and how to run it locally is worth its weight in gold. Inline comments that explain why something exists instead of what it does are the difference between guidance and noise.

Refactoring is where discipline shows up over time. Strong SPFx developers revisit their code. They simplify. They delete what’s no longer needed. They resist the temptation to stack hacks on top of hacks. This is where leadership lives, even if no one calls it that. Clean code tells the next developer, “I cared enough to make this easier for you.”

When your SPFx code earns respect, it’s not because it’s flashy. It’s because it’s solid. It works. It reads cleanly. It survives scrutiny. That’s the kind of reputation that follows you quietly from project to project.

Conclusion

Creating complex SPFx solutions that impress isn’t about showing off tricks or chasing the latest framework trend. It’s about taking responsibility for the full lifecycle of what you build. From concept to code, impressive SPFx work comes from architectural discipline, engineering for real-world conditions, and writing code that respects the people who will live with it after you move on.

Architectural discipline keeps your solutions from collapsing under their own weight. Engineering for reality ensures they survive users, data, and time. Professional craftsmanship turns your code into something others trust and build on.

Common SPFx Mistakes and How to Avoid Them

1,322 words, 7 minutes read time.

Introduction

If you’ve spent any time building web parts in SharePoint, you know the SharePoint Framework (SPFx) is both a blessing and a curse. It’s like wielding a high-performance engine: in the right hands, it can power sleek, modern SharePoint experiences; in the wrong hands, it’s a ticking time bomb of broken builds, version conflicts, and user complaints. The thing is, most developers don’t realize just how easy it is to shoot themselves in the foot when working with SPFx.

In this post, we’re going to break down the most common SPFx mistakes that trip up even seasoned programmers—and more importantly, how to avoid them. Think of this as a blueprint to build smarter, safer, and faster SharePoint solutions. Whether you’re a JavaScript veteran, a TypeScript enthusiast, or a React junkie, these lessons will save you headaches, lost hours, and maybe even a little reputation damage.

We’ll focus on three major categories where SPFx projects usually go off the rails. First, architecture and dependency management—because your code foundation is everything. Second, security and governance missteps—because sloppy permissions or untrusted scripts can get you into serious trouble. Third, performance, deployment, and monitoring errors—because a slow or broken web part is the fastest way to frustrate users and stakeholders. Let’s dive in.

Poor Architecture and Dependency Management

Think of SPFx architecture like building a custom motorcycle. If your frame is weak or your parts don’t fit, no amount of horsepower will make it ride well. In SPFx, “weak frame” usually comes from poor dependency management.

One of the most common pitfalls is over-reliance on floating dependencies, like using caret (^) or tilde (~) versions in your package.json. Sure, npm makes it easy to grab the latest version, but it’s also like leaving your garage unlocked. Different developers on the same team may end up running slightly different versions of libraries, introducing subtle bugs that are almost impossible to trace.

To avoid this, lock your dependencies. Use exact versions when possible (--save-exact), and freeze your builds with a lockfile before deployment. Tools like npm shrinkwrap can lock your versions reliably, ensuring everyone on the team is working with the same code. That’s the difference between a predictable build and a house of cards.

Another common misstep is not using library components for shared code. How many times have you seen the same utility functions copied across multiple web parts? It feels fast in the short term, but it’s a maintenance nightmare. One bug, one new feature, and suddenly you’re editing five different files instead of one. SPFx library components centralize shared code, letting you update once and propagate changes everywhere, keeping your codebase lean and consistent.

Finally, think about modern package managers. Tools like pnpm deduplicate dependencies, speed up installations, and reduce disk bloat. It’s not a silver bullet, but in large SPFx projects, it’s a lifesaver.

The takeaway here: architect your solution like a pro. Lock your dependencies, centralize shared code, and enforce strict version control. Your future self—and your teammates—will thank you.

Security & Governance Missteps

SPFx isn’t a sandbox. Code you ship in an .sppkg runs in the user’s browser context, meaning mistakes are visible to everyone with access. If you ignore security and governance, you’re not just risking bugs—you’re risking trust, data, and compliance.

One common blunder is ignoring Content Security Policy (CSP). CSP helps control which external scripts your web parts can load. Ignore it, and you’re basically leaving the back door open. Make sure you declare trusted script sources explicitly, and avoid pulling code from unverified CDNs. Treat CSP like the lock on your toolbox: it’s only effective if you respect it.

Next up: permissions. Over-requesting permissions is a rookie mistake. Don’t ask for write access if you only need read. Don’t request Graph scopes that aren’t critical. The principle of least privilege is your shield against accidental data leaks or compliance violations. Regularly review your permission requests and prune anything unnecessary.

Finally, governance matters. Who approves your SPFx packages? Who signs off on code before it hits the app catalog? Without a governance process, even well-intentioned developers can deploy unsafe or buggy code. Using tools to scan and validate your package contents before deployment is a must.

Remember: SPFx gives you power, but with great power comes responsibility. Treat your code like an enterprise citizen—secure, vetted, and accountable.

Performance, Deployment & Monitoring Errors

Even if your architecture is solid and your code is secure, performance missteps will make users curse your name. Slow web parts, broken scripts, and unoptimized bundles can ruin an otherwise polished solution.

Start with hosting. Many SPFx developers host assets directly in SharePoint or on unmanaged servers. This works at first, but it’s like running a marathon in flip-flops. For speed and reliability, host your assets on a proper CDN with caching enabled. Users will notice the difference the moment they open a page.

Bundle optimization is another often-overlooked area. Tree-shaking removes unused code, lazy-loading delays non-critical scripts, and minimizing your JS reduces payload size. Without these optimizations, your web parts will load slowly, especially on large pages or slow connections.

Deployment pipelines matter too. Manual uploads are risky—someone will inevitably skip a step. Implement CI/CD pipelines that handle building, testing, bundling, deploying to CDN, and publishing to the app catalog. Include automated scans for vulnerabilities, linting errors, and versioning validation.

Finally, don’t forget monitoring. Tools like Application Insights let you track errors, performance issues, and usage patterns. Without telemetry, you’re flying blind; with it, you can proactively fix issues before users even notice.

Performance and deployment aren’t glamorous, but neglect them, and your SPFx project collapses under its own weight.

Conclusion

Building SPFx solutions is powerful, but it’s also easy to make mistakes that cost time, money, and credibility. The three most common pitfalls are poor architecture and dependency management, security and governance oversights, and performance/deployment errors.

By locking your dependencies, centralizing shared code, respecting permissions, hosting assets properly, optimizing bundles, and monitoring your web parts, you’ll not only avoid headaches—you’ll build SPFx solutions that are robust, scalable, and respected.

Here’s my challenge: audit your current SPFx projects. Where are the vulnerabilities? Are your builds consistent? Are your permissions excessive? Pick one area to improve today. One small step can transform your next SPFx project from a maintenance nightmare into a rock-solid solution.
