GitHub
in GitHub, projects are kept in repositories, or repos for short
source
you can think of repos as folders
source
you can store anything in a repo, including data
source
many tech-focused jobs will require some GitHub knowledge
GitHub Pages: free web hosting
source
once you get your code on GitHub, they'll display those pages for free
source
and GitHub Pages perform better for viewers than Glitch
source
there are a few ways to put your code in GitHub:
the command line
we'll use Glitch
two phases:
1. initial setup
2. updating the code
1. initial setup
use a descriptive repository name (doesn't have to match your Glitch project name)
initialize with a README
2. updating the code
authorize (just the first time)
when you're done you'll have two URLs to keep track of:
1. the GitHub repo
https://github.com/ebrelsford/carto-single-layer/
like the code view in Glitch
https://github.com/ebrelsford/carto-single-layer/
this will always be at github.com
https://github.com/ebrelsford/carto-single-layer/
2. the GitHub Pages site
https://ebrelsford.github.io/carto-single-layer/
like the "show" view in Glitch
https://ebrelsford.github.io/carto-single-layer/
this will always be at github.io
https://ebrelsford.github.io/carto-single-layer/
likely issues
blank page!
in developer tools, JS and CSS aren't loading
the browser is looking at the wrong URL for styles.css
new Glitch projects often get files using /styles.css
/styles.css means "put /styles.css" right after the domain"
this works fine in Glitch
https://flaxen-bait.glitch.me/styles.css
but not in GitHub
https://ebrelsford.github.io/styles.css
since the GitHub URL ends with the repo name
https://ebrelsford.github.io/my-map/
so you want to load styles this way:
https://ebrelsford.github.io/my-map/styles.css
pretty straightforward fix—add . before the /
. means "look in this folder"
is GitHub worth the effort?
depends!
since many tech and tech-adjacent work uses GitHub, it's good to get familiar with it
it's a bit easier to keep organized than Glitch
Glitch puts sites to sleep when they're inactive
GitHub Pages won't do this
my recommendation: use Glitch for small experiments, GitHub for projects you want to keep around
if you want, you can register a domain and point it at GitHub
source
or for free,
you can make an "organization" in GitHub
you get organizationname.github.io
GitHub isn't just for hosting web sites
