| 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. | |
