This is a JS Worker file for the main sqlite3 api. It loads
sqlite3.js, initializes the module, and postMessage()'s a message
after the module is initialized:
{type: 'sqlite3-api', result: 'worker1-ready'}
This seemingly superfluous level of indirection is necessary when
loading sqlite3.js via a Worker. Instantiating a worker with new
Worker("sqlite.js") will not (cannot) call sqlite3InitModule() to
initialize the module due to a timing/order-of-operations conflict
(and that symbol is not exported in a way that a Worker loading it
that way can see it). Thus JS code wanting to load the sqlite3
Worker-specific API needs to pass _this_ file (or equivalent) to the
Worker constructor and then listen for an event in the form shown
above in order to know when the module has completed initialization.
This file accepts a URL arguments to adjust how it loads sqlite3.js:
- `sqlite3.dir`, if set, treats the given directory name as the
directory from which `sqlite3.js` will be loaded.
