<hr>
<div>Below is the list of test pages for the sqlite3 WASM
builds. All of them require that this directory have been
"make"d first. The intent is that <em>this</em> page be run
using:</div>
<blockquote><pre>althttpd -enable-sab -page index.html</pre></blockquote>
<div>and the individual tests be started in their own tab.
Warnings and Caveats:
<ul class='warning'>
<li>Some of these pages require that
the web server emit the so-called
<a href='https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Opener-Policy'>COOP</a>
and
<a href='https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Embedder-Policy'>COEP</a>
headers. <a href='https://sqlite.org/althttpd'>althttpd</a> requires the
<code>-enable-sab</code> flag for that.
</li>
<li>Any OPFS-related pages require very recent version of
Chrome or Chromium (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 (v110 as of 2022-12-02).

<div>The tests and demos...
<ul id='test-list'>
<li>Core-most tests
<ul>
<li><a href='tester1.html'>tester1</a>: Core unit and
regression tests for the various APIs and surrounding
utility code.</li>
<li><a href='tester1-worker.html'>tester1-worker</a>: same thing
but running in a Worker.</li>
<li><a href='tester1-esm.html'>tester1-esm</a>: same as
<code>tester1</code> but loads sqlite3 in the main thread via
an ES6 module.
</li>
<li><a href='tester1-worker.html?esm'>tester1-worker?esm</a>:
same as <code>tester1-esm</code> 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.
</li>
</ul>
</li>
<li>High-level apps and demos...
<ul>
<li><a href='fiddle/index.html'>fiddle</a> is an HTML front-end
to a wasm build of the sqlite3 shell.</li>
<li><a href='demo-123.html'>demo-123</a> provides a
no-nonsense example of adding sqlite3 support to a web
page in the UI thread.</li>
<li><a href='demo-123-worker.html'>demo-123-worker</a> is
the same as <code>demo-123</code> but loads and runs
sqlite3 from a Worker thread.</li>
<li><a href='demo-jsstorage.html'>demo-jsstorage</a>: very basic
demo of using the key-value VFS for storing a persistent db
in JS <code>localStorage</code> or <code>sessionStorage</code>.</li>
<li><a href='demo-worker1.html'>demo-worker1</a>:
Worker-based wrapper of the OO API #1. Its Promise-based
wrapper is significantly easier to use, however.</li>
<li><a href='demo-worker1-promiser.html'>demo-worker1-promiser</a>:
a demo of the Promise-based wrapper of the Worker1 API.</li>

(<a href='test-opfs-vfs.html?opfs-sanity-check&opfs-verbose'>same
with verbose output and sanity-checking tests</a>) is an
sqlite3_vfs OPFS proxy using SharedArrayBuffer and the
Atomics APIs to regulate communication between the
synchronous sqlite3_vfs interface and the async OPFS
impl.
