 # How this is built

 Gatsby has a [template for blogs](https://github.com/gatsbyjs/gatsby-starter-blog). Using
-
+```bash
 npx gatsby new blog https://github.com/gatsbyjs/gatsby-starter-blog
+```

 I let gatsby create an instance of the blog template for me. From this template I got going with `npx gatsby develop` and started off with deleting a lot of files I didn't need. I also did some changes to the style. I have absolutely no background in anything even remotely related to making things look good, so I just went with what I had in my mind at that very moment (any feedback and suggestions are very welcome). The `gatsby new` command did also initialize a [`git`]() repository so I just had to commit my new changes. For better availability I then pushed the repository to [my self-hosted git server](https://code.while-false.de/stephan/blog).

 # How this is run

 I mentioned `docker` before. [It seems to be officially supported](https://github.com/gatsbyjs/gatsby-docker). I just went with the documentation and tried to get it to run. First, I created a `Dockerfile` in the project with just one line of content:
-
+```docker
 FROM gatsbyjs/gatsby:onbuild
+```

 Then, I could build first the gatsby project with `npx gatsby build` and use the optimized output from that to build a docker image with `docker build -t while-false/blog .` from the context of my project root. Next, I started a container from the newly created image with `docker run -d --name blog -p 8080:80 while-false/blog`. It worked on my laptop for `localhost:8080`, I saw the blog I just built. Nice!

+title: Comments
+date: "2020-09-05T17:56:22.339Z"
+description: I would love to hear from you!
+---
+
+## Where do comments live?
+
+I built this blog with [`GatsbyJS`](https://www.gatsbyjs.org/), which is optimized for static content. It works great for everything that exists when I build the code and create another docker image. But now I want to add comments from my readers. Which of course aren't static and don't exist on compile-time. So it seems GatsbyJS would not be the right tool for the job.
+
+Luckily, GatsbyJS is expandable. There even is a [guide on how to integrate comments](https://www.gatsbyjs.com/docs/adding-comments/) in a blog on the gatsby website itself. But it assumes you just go and use some external service like disqus (although it does mention several alternatives). I didn't want to outsource that, the whole point of this blog is to run things myself and learn from that.
+
+What I found was [Commento](https://commento.io/). It focusses around privacy and can be [self-hosted](https://docs.commento.io/installation/self-hosting/) instead of using an external service. It even has docker support. I quickly set up my very own instance on my server:
+
+```bash
+docker run -d --name blog-commento \
+  -e "COMMENTO_ORIGIN=https://comments.while-false.de" \
+  -e "COMMENTO_POSTGRES=postgres://commentoDbUser:SuperSecretPassword@db_postgres/commento?sslmode=disable" \
+  registry.gitlab.com/commento/commento
+```
+*(In reality, I use a few more parameters and steps required for my specific hosting setup, which I will explain in a future post)*
+
+So my blog itself can still be static and throught the magic of gatsby's automatic optimization blazing fast, while the dynamic comments are handled by an external server, which I can fully control as I host it myself.
+
+## Include the comments in the blog
+
+Next, I followed the [documentation for commento](https://docs.commento.io/installation/self-hosting/register-your-website/) and registered the blog on my commento instance. Easy.
+
+Now to the tricky part. The static Gatsby.js website must embed the dynamic comments from the commento server. Again, I am lucky and found that [someone already did exactly that](https://itnext.io/adding-commento-to-react-apps-like-gatsby-871824fb57ae). With some small tweaks, this is what I use:
+
+```js
+import React, { useEffect } from 'react';
+
+/**
+ * Helper to add scripts to the page.
+ * @param {string} src The source path for the script to insert.
+ * @param {string} id The unique identifier for the script element to insert.
+ * @param {HTMLElement} parentElement The DOM element to insert the script into.
+ */
+const insertScript = (src, id, parentElement) => {
+  const script = window.document.createElement('script');
+  script.async = true;
+  script.src = src;
+  script.id = id;
+  parentElement.appendChild(script);
+  return script;
+};
+
+/**
+ * Helper to remove scripts from the page.
+ * @param {string} id The unique identifier for the script element to remove.
+ * @param {HTMLElement} parentElement The DOM element to remove the script from
+ */
+const removeScript = (id, parentElement) => {
+  const script = window.document.getElementById(id);
+  if (script) {
+    parentElement.removeChild(script);
+  }
+};
+
+
+const Commento = ({ id }) => {
+  useEffect(() => {
+    // If there's no window there's nothing to do for us
+    if (!window) {
+      return;
+    }
+    const { document } = window;
+    // In case our #commento container exists we can add our commento script
+    if (document.getElementById('commento')) {
+      insertScript('https://comments.while-false.de/js/commento.js', 'commento-script', document.body);
+    }
+    // Cleanup; remove the script from the page
+    return () => removeScript('commento-script', document.body);
+  }, [id]);
+  return <div id="commento" />;
+};
+
+export default Commento;
+```
+
+This component itself is evaluated at runtime (it uses `useEffect`, which gatsby understands as non-static). It dynamically loads the scripts required by commento. The commento component is then included in my default blog-post template component by adding the line `<Commento id={this.props.slug} />`. The slug is the part of the URL after the hostname, i.e. `004-comments/` for this page. Thus, commento differentiates which comment belongs to which page.
+
+Now, users can register and directly comment or comment anonymously with a required moderator review (which is me). Also, markdown, up- and downvoting, sorting, sticky, replies and moderation tools are included. Give it a try, I'd love to hear from you!
+
+In the next few days I will tinker around with commento's settings for moderation notification emails, custom styling and comment analytics (number of views and number of comments).
