Why Progressive enhancement in Remix? - Purpose & Use Cases

The Big Idea

What if your website could delight every visitor, no matter their device or connection?

The Scenario

Imagine building a website that looks great and works perfectly on your laptop, but when someone visits it on an older phone or with slow internet, the site breaks or becomes unusable.

The Problem

Manually trying to support every device and connection speed by writing separate code for each case is confusing, slow, and easy to forget. It often leads to broken features and frustrated users.

The Solution

Progressive enhancement lets you build a simple, working base first, then add extra features that improve the experience on better devices or browsers, so everyone can use your site without problems.

Before vs After

✗ Before

if (browserSupportsJS) { loadFullApp(); } else { showError(); }

✓ After

<main>Basic content here</main>
<script>loadExtraFeatures();</script>

What It Enables

It enables websites to work well for all users, no matter their device or connection, while still offering richer experiences where possible.

Real Life Example

A news site that shows readable articles on any device, but adds interactive maps and videos only if the browser supports them.

Key Takeaways

Start with a simple, functional base everyone can access.

Add enhancements that improve experience on modern devices.

Ensure your site never breaks for users with older or limited technology.
