Is it better to use SQLite3 or WebSQL with Node-Webkit?

Question

SQLite

Good day!
Wrote a web application for a client to automate some business processes. The problem is that the Internet may not be stable.
It was decided to write a Dekstop version using Node-Webkit and synchronize with the server when there is a connection.
What is better to use for the base? SQLite3 or WebSQL? I know that "under the hood" is the same SQLite, but still, what are the differences between them, what are the limitations?
The database can grow up to ~1 GB.
PS SQLite3 could not build under Node-Webkit 0.18.3 (win 32-bit). I did everything according to _ttp://www.technerium.ru/nwjs/vklyuchenie-sqlite3-v-proekt-nwjs
