In this tutorial, you are going to learn how to build a blog with Jekyll. A static website needs a source of content: in this example, we will deliver it using an API created with Strapi.

A static website contains Web pages with fixed content. Technically, it is a simple list of HTML files, which displays the same information to every visitor. Unlike dynamic websites, they do not require any back-end programming or database. Publishing a static website is easy: the files are uploaded on a simple Web server or storage provider. The two main advantages of static websites are security and speed: there is no database so it can not be hacked and there is no need to render a page for each request, which makes Web browsing faster.
To make their creation easier, numerous open-source static websites generators are available: Jekyll, Hugo, Gatsby, Hexo, etc. Most of the time, the content is managed through static (ideally Markdown) files or a Content API. Then, the generator requests the content, injects it in templates defined by the developer and generates a bunch of HTML files.
Note: the code source of this tutorial is available on GitHub.
Developed on top of Ruby, Jekyll makes static website creation super easy. It includes many features such as permalinks, categories, pages, and custom layouts. Write some Markdown files, customise your templates and you will get an easy to host website in seconds.
Last but not least, Jekyll is the static website generator powering GitHub Pages!
Thanks to its extensible plugin system, it provides a large set of built-in features: Admin Panel, Authentication & Permissions management, Content Management, API Generator, etc.
Unlike online CMSs, Strapi is 100% open-source (take a look at the GitHub repository), which means:
To make the magic happen, let's create a Strapi API and add some content.
Install Strapi using npm:
$ npm i strapi@alpha -g
Note: Strapi v3 is still an alpha version, but it will be fine for this tutorial.
Create a directory named
$ mkdir jekyll-strapi-tutorial
Scaffold your API inside it through a single command line:
$ cd jekyll-strapi-tutorial $ strapi new api
The CLI will ask you to choose your database: select MongoDB (currently better supported). Then, fill the database information. The default values should work if you correctly installed MongoDB.
Enter inside your project's folder:
$ cd api
Launch the Node.js server:
$ strapi start
Starting now, you should be able to visit the admin panel of your project: http://localhost:1337/admin.
Add your first user from the registration page.
Strapi APIs are based on a data structure called Content Types (equivalent of models in frameworks and Content Types in Wordpress).
Create a Content Type named
post with five fields:
text, select the WYSIWYG in the advanced options section.
relation: many posts related to one user.
Add some posts in the database. To do so:
Add New Post.
For security reasons, the API access is, by default, restricted. To allow access, visit the Auth and Permissions section for Guest role, select the
Post - find action and save. At this point, you should be able to request the list of posts.
The author API access is also restricted. Authorize anonymous access by selecting the
find (in "Users & Permissions" section) action and saving the form.
Great job, your API is ready! We can start developing the static website.
First, install the Jekyll CLI:
$ gem install jekyll bundler
In the folder
jekyll-strapi-tutorial that you previously created, generate your brand new blog:
$ jekyll new blog
Enter in your project's folder:
$ cd blog
Start the server:
$ bundle exec jekyll serve
At this point, you should able to see your fresh blog at http://localhost:4000.
When you manage a static website, your data can come from different sources: Markdown files, CSV files, a WordPress website (using the JSON REST API plugin), etc.
By default, Jekyll uses Markdown files to manage data. Fortunately, thanks to the plugin system, you can get data from any source.
In this example, we are using Strapi. Obviously, we are going to need a plugin compatible with Strapi APIs. Good news: we built it for you!
jekyll-strapi gem to your
Install the gem:
gem install jekyll-strapi
jekyll-strapi to your plugins list in
$ bundle install
This plugin need some configurations. Add the end of
_config.yml, add the following content:
First, we want to display the list of articles. To do so, we are going to instruct Jekyll to retrieve the list of posts:
Each Content Type must be listed in the
collections object. The
type field is used to build the URL requested. For example, if your type is
product, the requested URL will be
http://localhost:1337/product. The permalink is the URL structure you want to use for your blog posts. We could have chosen
/posts/:id, but slugs are more friendly.
After that, we need to display the data. Jekyll uses a theme system. By default, the used theme is minima. The theme's files are not generated in the Jekyll projects, but you can override every theme's template by creating a file with the same name in the
_layouts folder. To replace the existing home page content, create the folder
home.html inside it:
Finally, restart the server (
ctrl + c and
$ bundle exec jekyll serve) to let Jekyll consider these updates and admire your list of articles at http://localhost:4000.
At the top of the file, we indicate the layout we want to use in order to display the header and the footer.
jekyll-strapi exposes the data received from the API through the global variable
strapi, which is accessible from every template. To display the list of posts, we checked that the list
strapi.collections.posts is not empty. If it is the case, we loop on it to display each item.
As you can see, some fields are displayed using
|. The vertical line symbol is used by Jekyll's filters, which alter the way to display text. For example,
post.createdAt uses the
data_to_string to display the post's creation date in a more human friendly way.
Every entry includes an additional property named
url which represents the url of the record's page based on the permalink given in the configuration.
Our website now starts looking like a blog which is a good thing. However, an important part is still missing: the post’s details page.
Let's create the template and define the content displayed in a new file named
post.html located in the
The template displays the title of post, some meta data and convert the content from Markdown to HTML.
_config.yml we must add
output lines to indicate to Jekyll that we want to generate a new page for each post, using the template we previously created.
After restarting the Jekyll server, you should be able to see a new folder named
posts, in the
_site folder, containing the generated pages.
From now on, you can visit the detail page by clicking on URLs displayed on the homepage.
Articles are written by authors. They deserve a dedicated page.
The processes for creating author views and article pages are very similar. First, we create the template:
Let's add the the new collection in the config file:
Finally, restart the server and visit the author page from the article view's links.
Congrats! You’ve successfully built a super fast and easy-to-maintain blog!
Since the content is managed by Strapi, the authors can write post through a nice UI and developers only have to rebuilt the Jekyll blog in order to update the content.
Where to go next?
Feel free to continue this project to discover both Jekyll and Strapi advantages. Here are some features you can add: list of authors, post's categories, and comment system with the Strapi API or Disqus. You can also create other kind of websites (e-commerce shop, corporate website, etc.).
When your project is achieved, you will probably want to deploy it. The static website generated by Jekyll can easily be published on storage providers: Netlify, S3/Cloudfront, GitHub pages, GitLab pages, Heroku, etc. The Strapi API is nothing else than a simple Node.js API, so it can be hosted on Heroku or any Linux instance that has Node.js installed.
We hope you enjoyed this tutorial. Feel free to comment on it, share it, and let us know how you create static sites and manage their content.
