Spree Commerce VS vendure

A good system to study is Spree https://github.com/spree/spree. It has an inventory and billing system and supports different adjustments and sale configurations. If you don't want to use it wholesale it's a solid Rails application that does most of what you want so you can use it as solid inspiration.

Check out spree or similar ecommerce software. https://github.com/spree/spree

Spree Commerce: https://spreecommerce.org/

Maybe Spree?

I'd say Solidus and Spree are you best options rather than trying to roll out you own ecommerce solution.

When I was working on that company, that mobile ordering app, Counterless, I looked a lot at codebases like Spree, the Spree Commerce codebase. And that's how I learned a lot about how do you model an order with line items and things like that? I saw some amazing things that helped me develop an understanding and save a ton of time by looking at oh, they have a state machine. What are the ways that an order transitions through all these different states as it gets processed and charged? And how do you track all of those things?

After publishing Back-In-Stock Vendure plugin, we got our first issue reported almost immediately and it happened to be related to an issue with Typescript 3.7+ useDefineForClassFields flag in ts-config breaking Vendure BaseEntity initialization when consuming the plugin.

Vendure is a modern, open-source headless commerce framework built with TypeScript & Nodejs with an awesome plugin architecture to keep the monkey-business at bay.

medusa and vendure. i can only name these off the top of my head

The hardest part of your application will probably be the shop itself. I would recommend some kind of E-Commerce backend, for instance Shopify or Vendure. If you wanna go Open Source, then I'd suggest Vendure.

Vendure can use a number of DBs - MySQL/MariaDB, Postgres, SQLite etc. If you want to know about the actual schema, i.e. what tables there are and how they are related, I don't have a simple overview of that, but all the definitions can be found here: https://github.com/vendure-ecommerce/vendure/tree/master/packages/core/src/entity

We have plans in the upcoming v2 to make multi-vendor marketplaces a first-class use-case of Vendure, which will make it probably the only open-source framework of its kind for marketplace development. You can read more about the plans here: https://github.com/vendure-ecommerce/vendure/issues/1329
