- 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.
