@souravroy7864 starred it bro, btw, when running on browser, how does it handle data persistance?

S
@souravroy7864

@nhrdev it is not supposed to persist data on browser. Your files are yours you run in on playground and see the action then decide to take it to your application.

An embedded SQL database that runs in the browser, on servers, and locally at 5x DuckDB speeds on some queries is impressive. MIT licensed and built from scratch makes it worth watching closely.
