Shopify Polaris React Now Deprecated: The New Era of Polaris Web Components

One of the most critical building blocks we use when developing apps with Shopify is without a doubt Polaris. Polaris React, which has been offering React-based UI components for the Shopify Admin interface for years, has recently officially been officially deprecated was announced. I first noticed this through a big blue pop-up that popped up when I was searching for components in the Polaris documentation:

“Polaris for React is deprecated.”

So why is Shopify making such a change? And how will this new architecture affect us?

What is Framework-Agnostic?

The phrase that first caught my attention after seeing the warning”framework agnosticIt was a concept. It was the first time I came across a definition that was used so clearly, and I wanted to explore it in detail.

In the discussions on Stack Overflow, framework-agnostic structures are described as follows:

Not dependent on any framework,
Works compatible with React, Vue, Svelte or Vanilla JS,
which does not deteriorate when moved to different platforms,
Delivering more flexible and scalable interfaces in the long term
UI libraries are considered framework agnostic.

In short, your components if it only works because React works this is a React dependency;

but If the UI side stays intact even if you switch to Vue instead of React This is a framework-agnostic approach.

Shopify Polaris Is Now Moving Forward Over Web Components

Shopify summarizes Polaris's new roadmap as follows:

A single unified UI kit
Common structure covering Admin, Checkout, Customer Accounts, and other Shopify surfaces
Fully Web Components based on standards
React, Vue and even without any framework
Shopify's own Lightweight and modular components served from CDN

Along with this architecture:

❌ Polaris React → No longer available

✅ Polaris Web Components → New standard

Formerly limited to React, Polaris is now completely “rid of React dependency”. This means a freer ecosystem in the long run, especially for Shopify App developers.

My First Experiences: Flexible but There's Still a Way to Go

The first thing I see when I tinker with the new Polaris Web Components a bit:

more supple,
more modern,
more framework-independent It offers a structure.

But on the other side:

The list of “common bugs” is quite fluffy,
Documentation is still in development,
The stability of the components is variable from time to time,
In some cases it is difficult to carry React habits naturally.

I'm thinking of waiting for the winter update especially in my own projects; it doesn't feel quite “ready” for the production environment at the moment.
