  </p>

  <p>
    This page lists the SQLite3 APIs exported
    by <code>sqlite3.wasm</code> and exposed to clients
    by <code>sqlite3.js</code>. These lists are generated dynamically
    by loading the JS/WASM module and introspecting it, with the following
    caveats:
  </p>

  <ul>
    <li>Some APIs are explicitly filtered out of these lists because
      they are strictly for internal use within the JS/WASM APIs and
      its own test code.
    </li>
    <li>This page runs in the main UI thread so cannot see features
      which are only available in a Worker thread. If this page were
      to function via a Worker, it would not be able to see
      functionality only available in the main thread. Starting a
      Worker here to fetch those symbols requires loading a second
      copy of the sqlite3 WASM module and JS code.
    </li>
  </ul>
