                Switching the lights on: Hugo vs Hugo config files

                        Switching the lights on: Hugo vs Hugo config files
> A simple Hugo blog setup
The story of getting codewithhugo.com up and running.
The tl;dr is the following: 

I always rave about my blog setup, it’s simple, fast and just works
I used Hugo, “The world’s fastest framework for building websites”, a static site generator
I used a theme, casper-two, which is a Hugo port of the https://ghost.org/ default theme
I deployed to GitHub pages behind Cloudflare.

Why I didn’t build my own website 🏃‍♂️
I’m not a designer, and Code with Hugo wasn’t about me learning or showing off my website-making skills, it was about writing content consistently.
That’s why I used a template, Hugo and GitHub pages. It’s a static site with a CDN (Cloudflare) in front so pretty much nothing can go wrong. That means I have to focus on the content.
Picking a theme and overriding little things 🖼
Casper Two, the ghost.org default theme is awesome.
I tweaked a couple of things, as you can see in my static/overrides.css:
.site-title {
    font-weight: 200;
    font-size: 8rem;
}
.collection-title {
    text-transform: uppercase;
    font-size: 6rem;
    font-weight: 300;
}
.site-header:before {
    background: rgba(0, 0, 0, 0.5);
}
// This was only needed when I enabled pygments for syntax highlighting
.site-wrapper {
    min-height: auto;
}
.highlight {
    width: 100%;
}

Adding that stuff in config.toml:
[params]
    customCSS = "overrides.css"

That’s all the CSS I wrote 🙂 .
Enabling syntax highlighting 🎨
codewithhugo.com didn’t have syntax highlighting for a while, 😕 and I even started whining.

I tried a couple of times to enable it, it was meant to be as simple as putting the following in config.toml:
pygmentsUseClassic=false
pygmentsCodefences=true
pygmentsUseClasses=true

This stumped me for months, finally it turns out I was doing this
[params]
  pygmentsUseClassic=false
  pygmentsCodefences=true
  pygmentsUseClasses=true

Classic case of blinders being on.
As part of this process I got highlight.js working, but in keeping with the “It’s a static site so pretty much nothing can go wrong” it felt a bit wrong to use a client-side library to highlight stuff.
Since syntax highlighting is done at build-time, no highlight.js JS in layouts/partials/js.html :

If you want it to actually look nice we need to generate the syntax.css:
$ hugo gen chromastyles --style=monokai &gt; ./static/syntax.css

And hook it up in config.toml:
[params]
  customCSS = [
    "overrides.css",
    "syntax.css"
  ]

Image and things 🤳
Resize using imagemagick
Create a /static/img folder using:
$ mkdir -p static/img

Then we can resize whatever image I’m going to use (usually for the post cover photos):
$ convert my-image.jpg -resize 1500x1500 ./static/img/my-image.jpg

Convert PNG to JPG
I use Alchemy to convert from PNG to JPG https://dawnlabs.io/alchemy/, although I thing ImageMagick can do it as well.
Deployment and more
Deployment script
./scripts/deploy.sh, as taken from the Hugo docs:
#!/bin/bash
echo -e "\033[0;32mDeploying updates to GitHub...\033[0m"
# Build the project.
hugo # if using a theme, replace with `hugo -t <yourtheme>`
# Go To Public folder
cd public
# Add changes to git.
git add .
# Commit changes.
msg="rebuilding site `date`"
if [ $# -eq 1 ]
    then msg="$1"
fi
git commit -m "$msg"
# Push source and build repos.
git push origin master
# Come Back up to the Project Root
cd ..

“Cleaning up” with Node and npm scripts 🙄
This is the full package.json (minus the stuff that’s not necessary):
{
    "name": "codewithhugo",
    "description": "Repo for content of codewithhugo.com.",
    "config": {
      "syntax": "static/syntax",
      "overrides": "static/overrides",
      "images": "static/img"
    },
    "scripts": {
      "build": "concurrently --names \"SYNTAX,OVERRIDES,IMAGES\" -c \"bgBlue.bold,bgMagenta.bold,bgYellow.bold\" \"npm:build:css:syntax\" \"npm:build:css:overrides\" \"npm run build:imageoptim\"",
      "predeploy": "npm run build",
      "deploy": "./scripts/deploy.sh",
      "serve": "./scripts/serve.sh",
      "start": "npm run dev",
      "dev": "concurrently --names \"CSS,HUGO\" -c \"bgBlue.bold,bgMagenta.bold\" \"npm:watch:css\" \"npm:serve\"",
      "watch:css": "concurrently \"npm run build:css:syntax -- --watch --map inline\" \"npm run build:css:overrides -- --watch --map inline\"",
      "build:css:syntax": "csso -i $npm_package_config_syntax.css -o $npm_package_config_syntax.min.css --stat",
      "build:css:overrides": "csso -i $npm_package_config_overrides.css -o $npm_package_config_overrides.min.css --stat",
      "build:imageoptim": "imageoptim $npm_package_config_images"
    },
    "author": "Hugo Di Francesco",
    "homepage": "https://github.com/HugoDF/codewithhugo#readme",
    "devDependencies": {
      "concurrently": "^3.6.0",
      "csso-cli": "^1.1.0",
      "imageoptim-cli": "^2.0.3"
    }
}

Let’s walk through what happens when I run npm run deploy, these three tasks are the main ones:
"build": "concurrently --names \"SYNTAX,OVERRIDES,IMAGES\" -c \"bgBlue.bold,bgMagenta.bold,bgYellow.bold\" \"npm:build:css:syntax\" \"npm:build:css:overrides\" \"npm run build:imageoptim\"",
"predeploy": "npm run build",
"deploy": "./scripts/deploy.sh",

A feature of npm is that if you have a script called something  you can defined another script presomething that will run before something whenever it’s called.
So before deploying, we npm run build.
npm run build runs a couple of tasks in parallel with concurrently (https://www.npmjs.com/package/concurrently): 

npm:build:css:syntax which is concurrently-specific shorthand for npm run build:css:syntax
npm:build:css:overrides which is concurrently-specific shorthand for npm run build:css:overrides
npm run build:imageoptim

Minify and optimise CSS
"build:css:syntax": "csso -i $npm_package_config_syntax.css -o $npm_package_config_syntax.min.css --stat",
"build:css:overrides": "csso -i $npm_package_config_overrides.css -o $npm_package_config_overrides.min.css --stat",

build:css:syntax and build:css:overrides pretty much run the same command but on different files. Namely the files are $npm_package_config_syntax.css and $npm_package_config_overrides.css which interpolates npm_config syntax  and evaluate to static/syntax.css and static/overrides.css (see config.syntax and config.overrides in package.json. We use https://github.com/css/csso-cli, which pretty much just minifies the CSS.
The optimised CSS files get output as static/syntax.min.css and static/overrides.min.css, which I also update in the config.toml:
[params]
  customCSS = [
    "overrides.min.css",
    "syntax.min.css"
  ]

Imageoptim
A similar approach is used for build:imageoptim:
"build:imageoptim": "imageoptim $npm_package_config_images"

It runs imageoptim-cli on the contents of $npm_package_config_images (which expands to static/img).
Running in development mode
Now that I’ve got a build step in place… the problem is that I need to watch for changes etc in development as well, which are the following scripts, from package.json:
"serve": "./scripts/serve.sh",
"start": "npm run dev",
"dev": "concurrently --names \"CSS,HUGO\" -c \"bgBlue.bold,bgMagenta.bold\" \"npm:watch:css\" \"npm:serve\"",
"watch:css": "concurrently \"npm run build:css:syntax -- --watch --map inline\" \"npm run build:css:overrides -- --watch --map inline\"",

./scripts/serve.sh:
hugo serve . -F
# -D will serve even draft posts
# -F will serve future posts

I like not having to change the dates of my posts when they’re not ready to be published yet, so I use the -F flag. If I don’t want a certain post to appear in development I’ll use draft: true in the frontmatter.
npm run dev just runs the csso-cli tasks in watch mode as well as the Hugo dev server.
Getting a full RSS feed 😄
The default Hugo RSS feed doesn’t have the full post contents, it just has the excerpt (what would display on the homepage tiles in my case).
The problem with that is… well that the RSS feed doesn’t have full post contents.
I knew it was a problem but as usual I never got round to fixing it until I embarrassed myself while promoting it 😄:

And my reply to that:
> Hey there, I write at https://codewithhugo.com, I don’t think the RSS feed I’ve got actually has the full posts though 🙈— Hugo Di Francesco (@hugo__df) 21 July 2018
To fix that I found https://randomgeekery.org/2017/09/15/full-content-hugo-feeds/, (where there’s a full explanation of what we’re doing). Essentially it boils down to creating the following 
layouts/_default/rss.xml:
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
<channel>
<title>if eq  .Title  .Site.Titlewith .Title on </title>
<link/>
    <description>Recent content if ne  .Title  .Site.Titlewith .Titlein  on </description>
<generator>Hugo -- gohugo.io</generator>with .Site.LanguageCode
    <language></language>with .Site.Author.email
    <managingeditor>with $.Site.Author.name ()</managingeditor>with .Site.Author.email
    <webmaster>with $.Site.Author.name ()</webmaster>with .Site.Copyright
    <copyright></copyright>if not .Date.IsZero
    <lastbuilddate>.Date.Format &quot;Mon, 02 Jan 2006 15:04:05 -0700&quot; | safeHTML</lastbuilddate>
    with .OutputFormats.Get &quot;RSS&quot;
        printf &quot;<span class="nt">&lt;atom:link</span> <span class="na">href=</span><span class="s">&quot;%q&quot;</span> <span class="na">rel=</span><span class="s">&#39;\&quot;self\&quot;&#39;</span> <span class="na">type=</span><span class="s">&quot;%q&quot;</span><span class="nt">&gt;&lt;/atom:link&gt;</span>&quot; .Permalink .MediaType | safeHTML

    range .Pages
    <item>
<title></title>
<link/>
        <pubdate>.Date.Format &quot;Mon, 02 Jan 2006 15:04:05 -0700&quot; | safeHTML</pubdate>
        with .Site.Author.email<author>with $.Site.Author.name ()</author>
        <guid></guid>
<description>.Content | html</description>
</item>

    </channel>
</rss>

Which is just the default template except instead of:
<description>.Summary | html</description>

We do:
<description>.Content | html</description>

This make the built index.xml file huge since it’s putting every post’s full contents, so again on https://randomgeekery.org/2017/09/15/full-content-hugo-feeds/, I decided to limit the number of feed items to 15 (instead of 20 suggested in that post) that’s an update in config.toml:
rssLimit = 15

Full credit for this to this post https://randomgeekery.org/2017/09/15/full-content-hugo-feeds/, which actually explains the how and why of what has been done.
Cloudflare setup
I flipped on a couple of settings, notably forcing HTTPS: Cloudflare Dashboard > Crypto > Always use HTTPS > On and in the same section Crypto > Automatic HTTPS Rewrites > On.
I increased the Caching > Browser Cache Expiration to 8 days (could/should be more but I don’t want to have to version my assets) and switched on Caching > Always Online™ so that should GitHub Pages fall down, Cloudflare will still serve my content and all would be well.
That’s pretty much all of my Hugo setup for codewithhugo.com short of a couple of extra images and setting strings in config.toml.
