Store API Cleanup #3169

Since Shopware 6 has an API first approach, IMHO you should concentrate to improve the full page caching support. For example in https://github.com/shopware/platform/blob/trunk/src/Core/Content/Product/SalesChannel/Listing/ProductListingRoute.php#L88 by supporting more GET requests you can make use of the internal full page cache. If this is not possible, there is a way to convince the FPC with a bit of trickery to cache even POST/Search requests.

The benefit would be high: Having only a minimal bootstrapping for store-api requests would greatly improve loading time. Especially if you need to access multiple endpoints on the first time (loading menu, products, manufacturers, ... on first visit)

We found the following existing issues which may help or are related to your topic:

• WIP: Improve Store API Specification
• Allow usage of the store api in app scripts
• Price fields in store api
• API documentation
• Store API ignores active and maintenance mode flags of sales channel
• Store API stopped responding after multiple Login/Logout calls
• [GitHub] Define Store API context route as service.
• API Versioning: Documentation
• Remove open-api-schema call from administration

Will be part of the HTTP Cache rework and in some kind of the read optimized storages (#3165)
