# Technical Information ## Does ScandiPWA Support TypeScript? When developing extensions and theme overrides, developers are free to choose any technology they wish, including TypeScript. However, ScandiPWA doesn't support TypeScript yet. Our team is currently working on a migration of the code to TS. You can follow the roadmap at [scandipwa.com/phase-two](https://scandipwa.com/phase-two). ## 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
