How to break (and rebuild) the Jamstack

How do I make the codebases behind my minimum viable build tutorials?
ID the magic words
It’s been joked that naming things is one of the hardest problems in computer science, so I like to figure out why authors of existing Jamstack-ready codebases used the words they chose.
When writing a brand new CMS content model or theme from scratch, I explore how thorougly I can avoid using any of the following words when naming file, folders, variables, map keys, objects, functions, and classes:
- slug
- permalink
- url
- path
- theme(s)
- template(s)
- layout(s)
- include(s)
- component(s)
- page(s)
- post(s)
- name
- title
- data
- content
- body
- head
- header
- footer
This challenge helps me identify “magic words” that serve as handy shortcuts in content management systems or static site generators.
While I’m fine in 11ty and Gatsby, I still haven’t found a way to make Jekyll generate a URL from the value assigned to a Markdown file’s front matter key of afterTheDomainName
without duplicating the value in the file’s filename or in a front matter key called slug
or permalink
.
Have you?
Slowly reintroducing common names can reveal unexpected conflicts between various tools’ magic words.
Attempting to use the word slug
when building a Jekyll theme that I was also trying to make compatible with Stackbit CMS, I discovered that slug
seems to have special behavior in a stackbit.yaml
file managing new-Markdown-file creation.
I haven’t finished exploring, but this might mean avoiding the word slug
in my Markdown data or Jekyll theme, instead using filenames or permalink
.
Don’t forget: it’s not a great idea to leave strange names like xyzzy
or afterTheDomainName
sprinkled throughout your data or template as you build a real theme. Look around other people’s open-source code, find the standards, and consider naming things accordingly.
Update: In response to this post, Alan Smith suggested names like p_ost
and permalin_k
and I love this idea. I spend too much energy inventing awkward synonyms like afterTheDomainName
for slug
, and Alan’s pattern definitely reminds me to avoid names I’ll forget in 3 weeks like xyzzy
.
Meet in the middle
Typically, I work both “up from scratch” and “down from existing examples” concurrently.
Up
- Starting with an empty folder, I tease out how few files besides
index.html
a static site generator will let me use to make a single web page from it. - Next, I try using an
index.md
file containing a front matter property ofmessage: Hello World
, without any content below its front matter, and some layout templates containing my HTML, to see how few files I need to generate a single web page.- (The notion of a single primary content area isn’t always easy to translate to equivalent headless CMS content models, I don’t usually bother to figure out how a static site generator uses it. If I do, I make sure I understand the impacts on my theme of trying to change it to work with a headless CMS.)
- Next, I see if I can rename and move that file to something more like
/allMyMarkdown/onlyPage.md
and still render the page to the web site’s root domain. - Then I see if I can use a
mySinglePage.json
to do the same thing. - I try playing with multiple
.md
or.json
files, using some property of them to determine output URL, and build multiple pages within a site. - I try to repeat these steps, pulling the data from which I intend to build my site from a headless CMS’s API rather than from within the same filesystem as my SSG template configuration files.
Down
I’m no genius, so I usually tear apart other programmers’ open-source themes to achieve the goals above.
- How many files can I remove from this Sanity-11ty starter, and how many lines of code can I remove from each file, and still make it work?
- What do all these Contentful-Gatsby and Contentful-Hugo starters seem to have in common that comes down to the essence of “talking to Contentful’s API”?
Vary deployment
Deployment itself is something that needs to be figured out – “minimum” codebases may vary by deployment environment.
- CloudCannon builds a Jekyll site for me without my providing it a
Gemfile.lock
(or even a Gemfile? can’t remember). - Netlify requires a
Gemfile
for sure, and I believe also aGemfile.lock
. Anetlify.toml
file rarely hurts, either. - Building and running a web site on my personal computer with a static site generator requires installing a massive Ruby, Node.js, or Go codebase.
