Real World Example: Build Web Apps - not M365 or Teams Apps

Build web apps for Microsoft 365 instead of relying on native apps. Gain flexibility and access to latest tools. Learn from real world examples in this article.

In my previous article, I discussed the benefits of building web apps as the foundation for your Microsoft 365 or SharePoint apps. This approach contradicts most of the guidance and examples that focus on building web parts for SharePoint using the SharePoint Framework (SPFx), or using native Microsoft Teams-based solutions with tools like Yo Teams or the VS Code Teams Toolkit.

My main point was that if you focus on building web apps for Microsoft 365 instead of relying on the scaffolding tools and infrastructure that Microsoft provides, you will have much more flexibility in building Microsoft 365 apps.

I was pleasantly surprised by the reactions and passionate responses that I received from that article. It wasn’t just the quantity of reactions, but the overwhelming sense of agreement that caught me off guard. This week, I want to continue with that theme and highlight some of the experiences shared by my readers, rephrasing and emphasizing them along the way.

Okay, let’s return to the idea of creating web apps for Microsoft 365 instead of using native Microsoft 365 apps. I received a few responses from people who agree with this concept, including this one 👇 from Gabor, who mentioned recent moves by Microsoft:

Gabor: 'Preach it, Andrew. Right on! It is interesting to see the new direction with initiatives like Syntex Repository Services. Some of the SP Services are becoming headless, and that is the right direction IMO. This makes your point even more valid.'

Gabor Fari: "Right on! … This makes your point even more valid."

Building web apps provides more options

Most of the other responses were in line with what was best summed up by Juan. These all addressed points that I didn’t give enough attention to in my newsletter:

Juan: 'I moved away from SPFx or M365 specific dev a long time ago. Seems like a lot of the tech moved from dotnet to full stack development. Most of the time the scaffolds, templates and Microsoft specific templates didn’t move fast enough or were mature enough to base development on. Either way I build applications in general. I too look at graph or other Microsoft specific tools and platforms as extensions and integrations.'

Juan Larios: "the scaffolds, templates and Microsoft specific templates didn’t move fast enough"

When you tightly couple your solutions to Microsoft’s dependencies, toolchains, and project scaffolding, you may not be able to use some of the latest tools available. For instance, the SPFx still only supports React v17.0.1, which was released almost three years ago in October 2020. Meanwhile, React v18, the most recent major release, has been available to developers for over a year since March 2022.

This means that if you create solutions using the SPFx and Microsoft’s SPFx scaffolding, you may be restricted to using outdated features. This is because the SPFx and SharePoint Online do not yet support the latest features.

Microsoft Teams, on the other hand, is different because most of the web interfaces run within an <iframe>. Thus, they are not dependent on the host’s capabilities. This means that you can safely upgrade to different versions of React.

Use Microsoft tools, hosts, and clients as extension points

Moreover, I agree with Juan’s point about using Microsoft-specific tools and platforms as extension points or integration points, rather than the core platform for app development. This is precisely how I approach building apps using these tools. I use the native capabilities as extension points for the web apps that I create.

Building Microsoft Teams apps as web apps

Juan provided an excellent example of how to build apps for Microsoft Teams, which was well articulated:

Juan: 'I did away with the Microsoft toolchain and built my own Microsoft Teams template using NextJS and ReactJS and wrote all the auth flows directly into the app.'

Juan Larios: "I … built my own Microsoft Teams template using NextJS and ReactJS."

Typically, frameworks like React.js or Next.js offer various project templates and tools to help developers start building apps quickly. However, you can take it a step further and create your own project templates to enhance productivity.

Take a look at what Juan did:

Juan: 'My small little team did more in 6 months with these toolkits we created internally than the MS Teams Toolkit.'

Juan Larios: "My small little team did more in 6 months with our toolkits than the MS VSC Teams Toolkit."

I believe this is an excellent example that perfectly illustrates my point. It demonstrates what I was advocating and why you should consider it.

Have you tried this approach with your Microsoft Teams, SharePoint, or Microsoft 365 apps?

Does it make sense to you or do you have any questions?
