But Astro.js is being used by Ikea, plus a number of other e-commerce retailers.

These large companies use all kinds of tech across a huge number of projects. I hardly see how that can really be taken as a signal of the target audience. Most of these companies are using React in some capacity, so does that fall into the same category?

We're building an e-commerce retailer platform optimized for SEO so it makes sense for us since the objectives are the same.

I also wouldn't compare an Ikea to a Walmart or a Target. The latter surface massive catalogs that span multiple brands. Ikea is no small startup, but I don't put them at the same scale as Walmart and Target in terms of e-commerce.

For anyone else that wants to use React (I also advise against this), I'd personally recommend a React Vite SPA.
