I'm not sure what this means… sqlite isn't available to use in any browser. Not to mention, it has nothing to do with JavaScript on the web.
Snowpack is for bundling ES modules to build web applications. Nothing mentioned in your comments works to build a client-side web application. If this your comment was some sly remark, it's totally lost on me.
Also if your needs are simple you can just write a cgi script (provided you don't need too many RPS.)
