Sylius VS Slim

I think it would be difficult (or much harder) to build something like Sylius on top of Laravel. Especially if you want good code-coverage by tests.

For the development of high-scaling applications and responsive websites, open source headless commerce architecture has become the go-to option in recent years because of its flexibility, scalability, and agility. However, choosing the best open source headless ecommerce platform can be challenging. To help you navigate this complex landscape, this article compares two popular open source solutions: Medusa and Sylius.

Checkout Sylius. Try to run it and modify it in some way. Pretty big codebase and project. If you can modify it without directly rewriting the Syius code (like overloading Symfony services and so on...) you can be confident in your skills.

Can you tell me what exactly is wrong in language with code like this? Do note that this is still old <7.4 version, and version 8.0 and 8.1 gave us many goodies like constructor promotion, match, enums, throw expressions...

Just go with Shopify/Vercel. I've been hearing nice things about https://sylius.com/ too.

Sylius: https://sylius.com/

I would say Sylius is your best bet: https://github.com/Sylius/Sylius but I am sure there are many more.

Take a look at this: https://sylius.com/ it's opensource, based on Symfony and might be better than everything you mentioned.

Not sure what your needs are but yes I would use a framework and since you mentioned e-commerce I would take a look at this: https://github.com/Sylius/Sylius

Slim is a micro PHP framework used for web development with 11.7k stars and 2k forks on GitHub. It has a simple and intuitive API development process. It is a micro-framework, meaning you only get a minimum of support for HTTP requests and forwarding requests to appropriate controllers. So the question is, why should you choose a micro-framework? Because it offers you flexibility and high extensibility.

Slim 4, a minimalistic PHP micro-framework, offers middleware support to easily add CORS headers. Middleware in Slim acts like a series of layers through which your app sends a request. One such layer can be responsible for adding CORS headers.

SlimPHP 3 Skeleton app shows this as well: https://github.com/slimphp/Slim-Skeleton/blob/3.1.8/public/index.php

How hard did you look? There are plenty out there. FastRoute, Phroute, based on FastRoute, with basic middleware, League/Route - routing with middleware, using FastRoute, PSR 7 & 15, Slim Framework, at it's core, it like League/Route, etc. None of these require a full framework to use.

You can have the container call in a config folder with a file called dependencies or how ever you want. A few existing examples of this is here - Slim calls this app/dependencies in this skeleton project and Odan's Skeleton has this as config/container in their project.

Maybe use this if you don't like to dive into bigger frameworks: https://www.slimframework.com/
