I’ve not personally used it. There is some chat around adding PouchDB (which allows for synchronization of multiple databases), however I’ve not seen any release date as of yet, see feature request: PouchDB for data sync when offline
Do you use NodeJS? I see that there’s a NodeJS NPM package for LiteSync: http://litesync.io/en/install-nodejs.html
You could install the package and create a custom module to expose the LiteSync operations to Wappler, see Wappler Extensibility - Writing Custom Modules and Formatters for Server Connect
This is fairly advanced however so could be tricky to implement.
What is your use-case?
