 This repo is a fork of and wrapper around sql.js to provide a read-only HTTP-Range-request based virtual file system for SQLite. It allows hosting an SQLite database on a static file hoster and querying that database from the browser without fully downloading it.

It could also be useful to other applications, the code is in [lazyFile.ts](./src/lazyFile.ts). It might also be useful to implement this lazy fetching as an [SQLite VFS](https://www.sqlite.org/vfs.html) since then SQLite could be compiled with e.g. WASI SDK without relying on all the emscripten OS emulation.
