sqlite-js: Universal SQLite APIs for JavaScript

Currently provides a NodeJS driver and a better-sqlite3 driver.

Future work:

• Implement update notifications.
• Well-defined error handling behavior.
• Proper concurrency testing.
• CJS build

@sqlite-js/driver

This is a universal driver API and utilities for implementing drivers.

The APIs here are low-level, and should not be used directly by most apps. It is however a good target for other libraries.

@sqlite-js/driver/node

This is a driver implementation for NodeJS based on the experimental node:sqlite package.

This has some severe limitations, such as no extension support. Therefore not usable by Powersync.

@sqlite-js/better-sqlite3-driver

This is a driver implementation for NodeJS implementation based better-sqlite3. A good driver for PowerSync on NodeJS.

@sqlite-js/api

This contains a higher-level API, including transaction support. This is mostly a proof-of-concept right now, as a more fully-featured alternative to the current PowerSync query APIs.

benchmarks

Benchmarks comparing direct usage of better-sqlite3, node:sqlite, sqlite3 and the APIs here. The implementation here can generally not be faster then better-sqlite3 / node:sqlite, since it adds a layer on top of that. However, the performance gets close when using pipelining.

Using a connection pool involves worker threads which does significantly slow down the benchmarks. We do get close again when using pipelining or batching via JSON1.

This looks amazing. There are some nice gems in here.
