<h1>Testing export/import of Olm devices in the browser</h1>
<ul>
<li>
Make sure you built the current version of the Matrix JS SDK
(<code>yarn build</code>)
</li>
<li>
copy <code>olm.js</code> and <code>olm.wasm</code>
from a recent release of Olm (was tested with version 3.1.4)
in directory <code>lib/</code>
</li>
<li>start a local Matrix homeserver (on port 8008, or change the port in the code)</li>
<li>Serve this HTML file (e.g. <code>python3 -m http.server</code>) and go to it through your browser</li>
<li>
in the JS console, do:
<pre>
aliceMatrixClient = await newMatrixClient("alice-"+randomHex());
await aliceMatrixClient.exportDevice();
await aliceMatrixClient.getAccessToken();
</pre>
</li>
<li>
copy the result of <code>exportDevice</code> and <code>getAccessToken</code> somewhere
(<strong>not</strong> in a JS variable as it will be destroyed when you refresh the page)
</li>
<li><strong>refresh the page (F5)</strong> to make sure the client is destroyed</li>
<li>
Do the following, replacing <code>ALICE_ID</code>
with the user ID of Alice (you can find it in the exported data)
<pre>
bobMatrixClient = await newMatrixClient("bob-"+randomHex());
roomId = await bobMatrixClient.createEncryptedRoom([ALICE_ID]);
await bobMatrixClient.sendTextMessage('Hi Alice!', roomId);
</pre>
</li>
<li>Again, <strong>refresh the page (F5)</strong>. You may want to clear your console as well.</li>
<li>
Now do the following, using the exported data and the access token you saved previously:
<pre>
aliceMatrixClient = await importMatrixClient(EXPORTED_DATA, ACCESS_TOKEN);
</pre>
</li>
<li>You should see the message sent by Bob printed in the console.</li>
</ul>
