  69. <hr>
  70. <p>For reasons that are very relevant to the events of this past week, I have
  71. decided to finally get around to setting up a Mastodon / Fediverse account.</p>
  72. <p>I wanted to do it under my own domain, but last time I looked into this
  73. (three or so years ago), that was not possible if the domain was running
  74. something <em>other</em> than a Fediverse server - if you tried to follow
  75. <code>@andrew@aeracode.org</code>, it would come along to this website and try and do some
  76. ActivityPub on it.</p>
  77. <p>Faced with the idea of implementing proxy views for all the ActivityPub
  78. endpoints within my site, I instead opted to go back to the warm, stable
  79. embrace of Twitter (ahem), and come back and see how the fediverse had evolved in
  80. a few years' time.</p>
  81. <p>Well, here we are, and not only has the software and number of people improved,
  82. so has a few aspects of the underlying protocol (and look, ActivityPub is not
  83. great, but the only thing worse than implementing a flawed protocol is to try
  84. and invent yet another one to take its place).</p>
  85. <p>In particular, Fediverse servers now go looking for server and account (Actor)
  86. information via three URLs (which ones they want seems to differ by server):</p>
  87. <ul>
  88. <li><code>/.well-known/webfinger</code></li>
  89. <li><code>/.well-known/host-meta</code></li>
  90. <li><code>/.well-known/nodeinfo</code></li>
  91. </ul>
  92. <p>The last is static, and while the first two can be static if you just have one
  93. account on a server and never want to add any more, they're really meant to be
  94. dynamic and so should be proxied through to the fediverse server.</p>
  95. <p>So, faced with this much easier problem, that's what I did. This site still
  96. runs Django under the hood (though now powered by a sqlite database created on
  97. the fly - more on that in the future), and so doing this was a simple case of
  98. adding three views:</p>
  99. <div class="language-python3"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">proxy.views</span> <span class="kn">import</span> <span class="n">proxy_view</span>

  101. <span class="n">remote_url</span> <span class="o">=</span> <span class="p">(</span>
  102. <span class="s2">"https://fedi.aeracode.org/.well-known/webfinger?"</span>
  103. <span class="o">+</span> <span class="n">request</span><span class="o">.</span><span class="n">META</span><span class="p">[</span><span class="s2">"QUERY_STRING"</span><span class="p">]</span>
  104. <span class="p">)</span>
  105. <span class="k">return</span> <span class="n">proxy_view</span><span class="p">(</span><span class="n">request</span><span class="p">,</span> <span class="n">remote_url</span><span class="p">)</span>

  109. <span class="o">+</span> <span class="n">request</span><span class="o">.</span><span class="n">META</span><span class="p">[</span><span class="s2">"QUERY_STRING"</span><span class="p">]</span>
  110. <span class="p">)</span>
  111. <span class="k">return</span> <span class="n">proxy_view</span><span class="p">(</span><span class="n">request</span><span class="p">,</span> <span class="n">remote_url</span><span class="p">)</span>
  112. <span class="k">def</span> <span class="nf">wellknown_nodeinfo</span><span class="p">(</span><span class="n">request</span><span class="p">):</span>
  113. <span class="n">remote_url</span> <span class="o">=</span> <span class="s2">"https://fedi.aeracode.org/.well-known/nodeinfo"</span>
  114. <span class="k">return</span> <span class="n">proxy_view</span><span class="p">(</span><span class="n">request</span><span class="p">,</span> <span class="n">remote_url</span><span class="p">)</span></pre></div>
  115. </div>
  116. <p>This uses the <code>django-proxy</code> package to provide the <code>proxy_view</code>. You might
  117. also want to put in a view that redirects <code>yourdomain.com/@username</code>:</p>
  118. <div class="language-python3"><div class="highlight"><pre><span></span><span class="kn">from</span> <span class="nn">django.http</span> <span class="kn">import</span> <span class="n">HttpResponseRedirect</span>
  119. <span class="k">def</span> <span class="nf">username_redirect</span><span class="p">(</span><span class="n">request</span><span class="p">):</span>
  120. <span class="k">return</span> <span class="n">HttpResponseRedirect</span><span class="p">(</span><span class="s2">"https://fedi.aeracode.org/@andrew"</span><span class="p">)</span></pre></div>
  121. </div>
  122. <p>Hooking these up to the right URLs is the only other thing that's needed:</p>
  123. <div class="language-python3"><div class="highlight"><pre><span></span><span class="n">urlpatterns</span> <span class="o">=</span> <span class="p">[</span>
  124. <span class="o">...</span>
  125. <span class="c1"># Fediverse</span>
  126. <span class="n">path</span><span class="p">(</span><span class="s2">".well-known/webfinger"</span><span class="p">,</span> <span class="n">blog</span><span class="o">.</span><span class="n">wellknown_webfinger</span><span class="p">),</span>
  127. <span class="n">path</span><span class="p">(</span><span class="s2">".well-known/host-meta"</span><span class="p">,</span> <span class="n">blog</span><span class="o">.</span><span class="n">wellknown_hostmeta</span><span class="p">),</span>
  128. <span class="n">path</span><span class="p">(</span><span class="s2">".well-known/nodeinfo"</span><span class="p">,</span> <span class="n">blog</span><span class="o">.</span><span class="n">wellknown_nodeinfo</span><span class="p">),</span>
  129. <span class="n">path</span><span class="p">(</span><span class="s2">"@andrew"</span><span class="p">,</span> <span class="n">blog</span><span class="o">.</span><span class="n">username_redirect</span><span class="p">),</span>
  130. <span class="p">]</span></pre></div>
  131. </div>
  132. <p>That's what's up and running on this site right now, meaning you can type
  133. <code>@andrew@aeracode.org</code> into your favourite Fediverse client and it will
  134. understand that it's meant to actually go over to <code>fedi.aeracode.org</code> to ply
  135. its ActivityPub magic. If you're a CloudFlare Pages user, Jacob has
  136. <a href="https://jacobian.org/til/my-mastodon-instance/">a nice write-up</a> on how to do
  137. a similar trick over there.</p>
  138. <p>I'm happy, and crucially, I have avoided the temptation of writing my own
  139. ActivityPub/Mastodon-compatible server in Django. For now, at least.</p>
  140. <p>Incidentally, my server is hosted by <a href="https://masto.host">masto.host</a>, who
  141. I have nothing but good things to say about so far. I will happily pay $9 a
  142. month to avoid running yet another copy of all the various datastores that
  143. Mastodon needs, just for my own private instance.</p>
  144. <p><em>Note: Updated since first publication to add</em> <code>host-meta</code>
  145. <em>and the username redirect</em></p>
