The fundamental and most significant issue is that Liquid is a template language, making it challenging to develop. Custom databases, complex logic, and third-party service requests are impossible. Furthermore, when developers think about frameworks like Ruby on Rails, or Django, Liquid is a View layer. The developer has no direct access to the controllers and models that have been predetermined.
When you utilize Shopify as an e-commerce component of the headless system, you may encounter several typical difficulties. When comparing these two methods, we notice that both have their drawbacks. The most significant distinction is that, in the headless variation, the problems are conquerable at the cost of development resources. Still, the themed variant has no way to address fundamental issues. So let's describe how the new Hydrogen by Shopify addresses that problems.
The Storefront API's GraphQL types are used to generate and optimize the data for hydrogen. The structure of the information supplied to components, hooks, and utilities is based on the GraphQL types from the Storefront API. Hydrogen can also handle data from third-party sources, such as API-first CMSes like Prismic or Contentful, or even non-Shopify e-commerce systems.
In other words, Hydrogen provides a straightforward method to construct a contemporary Shopify shop at the expense of technological independence and software modifiability restrictions. It's also a wise business decision for Shopify. While the headless design is vendor-agnostic and enables freedom from any platform, Shopify, as a corporation, strikes back by providing tools for fast and contemporary development to its clients while maintaining tight ties between them.If Hydrogen was not designed to create headless shops, it implies that it is intended to take the place of Liquid.
