I received this email recently:
Subject: multi-page web apps
lately I’ve been following you through videos and texts and I’m curious as to why you advocate the use of multi-page web apps and not single-page ones.
Perhaps you can refer me to some sources where your position and reasoning is evident?
Here’s the response I sent…
You can find a lot of my reasoning laid out in this (short and free) online book I wrote called Resilient Web Design:
The short answer to your question is this: user experience.
The slightly longer answer…
For most use cases, a website (or multi-page app if you prefer) is going to provide the most robust experience for the most number of users. That’s because a user’s web browser takes care of most of the heavy lifting.
Navigating from one page to another? That’s taken care of with links.
Gathering information from a user to process on a server? That’s taken care of with forms.
This frees me up to concentrate on the content and the design without having to reinvent the wheels of links and form fields.
These (let’s call them) multi-page apps are stateless, and for most use cases that’s absolutely fine.
There are some cases where you’d want a state to persist across pages. Let’s say you’re playing a song, or a podcast episode. Ideally you’d want that player to continue seamlessly playing even as the user navigates around the site. In that situation, a single-page app would be a suitable architecture.
So that’s my reasoning. At least nine times out of ten, a multi-page approach is leaner, more robust, and simpler.
Like I said, there are times when a single-page approach makes sense—it all comes down to whether state needs to be constantly preserved. But these use cases are the exceptions, not the rule.
It’s kind of like when people ask, “Why don’t you have children?” Surely the decision to have a child should require deliberation and commitment, rather than the other way around.
When it comes to front-end development, I’m worried that we’ve reached a state where the more complex over-engineered approach is viewed as the default.
I hope I’m wrong. I hope that other developers will start to consider user experience first and foremost when making architectural decisions.
Anyway. That’s my answer. User experience.
