Below is the list of demo pages for the sqlite3 WASM builds. The intent is that this page be run using the functional equivalent of:

and the individual pages be started in their own tab. Warnings and Caveats:

• All of these pages must be served via an HTTP server. Browsers do not support loading WASM files via file:// URLs.
• Any OPFS-related pages or tests require:
  • That the web server emit the so-called COOP and COEP headers. althttpd requires the -enable-sab flag for that.
  • A very recent version of a Chromium-based browser (v102 at least, possibly newer). OPFS support in the other major browsers is pending. Development and testing is currently done against a dev-channel release of Chrome (v111 as of 2023-02-10).

The tests and demos...

• Core-most tests
  • tester1: Core unit and regression tests for the various APIs and surrounding utility code.
  • tester1-worker: same thing but running in a Worker.
  • tester1-esm: same as tester1 but loads sqlite3 in the main thread via an ES6 module.
  • tester1-worker?esm: same as tester1-esm but loads a Worker Module which then loads the sqlite3 API via an ES6 module. Note that not all browsers permit loading modules in Worker threads.
• Higher-level apps and demos...
  • demo-123 provides a no-nonsense example of adding sqlite3 support to a web page in the UI thread.
  • demo-123-worker is the same as demo-123 but loads and runs sqlite3 from a Worker thread.
  • demo-jsstorage: very basic demo of using the key-value VFS for storing a persistent db in JS localStorage or sessionStorage.
  • demo-worker1: Worker-based wrapper of the OO API #1. Its Promise-based wrapper is significantly easier to use, however.
  • demo-worker1-promiser: a demo of the Promise-based wrapper of the Worker1 API.
