What local databases does uxp support? Is it convenient to transplant SQLite and MySQL databases from CEP to uxp? Thanks.
UXP does not yet support any form of local database such as web SQL or IndexedDB. IndexedDB is used internally, but right now those APIs are not exposed to developers.
If you need to connect to a database, you’ll need to have a helper app that you can launch locally and communicate with via sockets, or connect to a REST endpoint externally.
