This is a common problem between different Jekyll environments.
We need to understand site.url
and site.baseurl
and in which situation we need them. Those variables don鈥檛 serve the same purpose.
site.url
By default, this variable is only used in page head for the canonical
header and the RSS link
. It鈥檚 also used in the xml feed to point to site resources as the software that will manage this feed doesn鈥檛 know resource鈥檚 urls.
This variable is only necessary for external systems.
site.baseurl
This variable indicates the root folder of your Jekyll site. By default it is set to ""
(empty string). That means that your Jekyll site is at the root of http://example.com
.
If your Jekyll site lives in http://example.com/blog
, you have to set site.baseurl
to /blog
(note the slash). This will allow assets (css, js) to load correctly.
See how assets are loaded in you head :
<link rel="stylesheet" href="/ocw/pluginfile.php/19489/mod_resource/content/3/_site/css/main.css">
that can also be :
<link rel="stylesheet" href="/ocw/pluginfile.php/19489/mod_resource/content/3/_site/css/main.css">
Now you have to test your site locally and to deploy it in production. Sometimes, the baseurl
is different and the jekyll build
may not work out of the box in one of those environment.
Here we have two solutions :
jekyll serve
Let鈥檚 imagine that your site lives in a github repository and is served at https://username.github.io/myProject
.
You can setup the baseurl
to /myProject
. and test your site locally with jekyll serve
, your site will be served at http://127.0.0.1:4000/myProject/
If, for one reason or another, you cannot use jekyll serve
, you can set a configuration file for both environment and jekyll build
depending on where you are deploying.
Let鈥檚 say we have the local site served at http://localhost
and the production site served at https://username.github.io/myProject
.
We leave the _config.yml
with url: https://username.github.io
and baseurl: /myProject
We create a new _config_dev.yml
with only url: https://localhost
and baseurl: ""
Now to test locally :
jekyll build --config _config.yml,_config_dev.yml
or
jekyll build --config _config.yml,_config_dev.yml --watch
When pushed on production, the jekyll build
command will use the default _config.yml
.
