Technical Information
Regarding technical decisions behind ScandiPWA

Does ScandiPWA Support TypeScript?

When developing extensions and theme overrides, developers are free to choose any technology they wish, including TypeScript.
However, ScandiPWA has no plans to change the language of the core code. JavaScript is preferred due to its simplicity.

ScandiPWA Cache

ScandiPWA uses the default Magento 2 cache control mechanism over the X-Magento-Tags-Pattern header.
It provides AddTagsToResponsePlugin to add entity headers to each GraphQL cacheable response.
A custom Cache entity (singleton) is used to gather all entities that were loaded during current request. Flushing happens on the default cache_flush events for most entities. CMS has its own event observers to track response/flush.
