Honestly if you just wanna get up and running quickly with the least hassle, go for Shopify. But if you actually want to build something, run it yourself and have no fees, you should check out my project vendure. It is built on Node with TypeScript and handles all the hard stuff for you. Combine it with our Remix storefront starter and you're most of the way there. Source: over 1 year ago

If OTS does not fit the bill, try one of the many open-source e-commerce frameworks that already solved all the hard parts for you, and allow you to just build out the custom parts specific to your requirements. Some suggestions: Vendure (my project), Saleor, Medusa, Sylius. Source: about 2 years ago

Another option is to take a framework that handles 80% of the stuff you need (customer/order/inventory managament, payments, shipping etc) but that gives you the flexibility to create whatever custom flows you need. Shameless plug: I work on just such a framework (vendure.io) and it might be worth checking out. Source: about 2 years ago

I'm happy to arrange a chat. Email me at [contact at vendure.io] and let's set something up. Source: over 2 years ago

I learned a lot from contributing to the https://vendure.io/ project and use the patterns in my everyday programming. It's NodeJS based, so it shouldn't be too complicated if you're using React! Source: over 2 years ago
