# sqlite.js

Another SQLite wrapper library.

Features:

* Incremental Blob IO via Readable / Writable Streams

* Custom VFSs with async implementations

* Coroutines / "multithreading" via Asyncify stack switching.

	* Enables cancelling a query: `Conn.prototype.interrupt()`

	* Run multiple queries  without needing SharedArrayBuffer or Worker

	* This library compiles SQLite with multithreading support

* An API with minimal construction / destruction.  Prefers 'borrowing' APIs that automatically aquire and release resources.

	* `ConnPool.prototype.borrow()`

	* Once webbrowsers get disaposable/asyncdisposable, then I might rework the APIs to better reflect the underlying SQLite objects.

* Tagged template literals

* Everything is optional: only include what you need.

	* Custom VFSs are optional (if you just want in-memory)

	* Custom scalar-functions are optional (if you don't need incremental blob IO, etc.)

	* Pool is optional

* Extensible

	* Modify how values are bound via the Bindable and Resultable traits in `sql.mjs/value.js`

	* Write your own implementation of custom VFS support.  Look at `sql.mjs/vfs/custom.js` to learn how.

	* Directly call sqlite3 functions via `sql.mjs/sqlite.js` and `sql.mjs/sqlite_def.js`

* Two VFS implementations

	* An HTTP VFS that uses HTTP range queries (if supported by the server) to incrementally query a database

		* Read-only

		* Works in browsers or Deno (uses the fetch api)

	* A browser VFS that operates on FileSystemFileHandle's and FileSystemDirectoryHandle's

		* Uses a virtual filesystem composed of file handles stored in an indexedDB database
