Why would anyone want to do this?

I wanted to start practicing writing a dev blog for my various interests. While my homepage is built on netlify and gatsby I didn’t want to scale out each potential project in my github account with with a deployment pipeline and have the nightmare of mainting it and applying security patches (I’ve had to update my homepage project several times after running npm audit fix).

While I appreciate github alerting me when ther is a new security vunerablity and I have a duty as an software engineer to respond . I want to write, create, and explore my interests for fun, not another job (One reason I never seriously considered playing Death Stranding).

Therefore I started exploring – or rather rediscovering – using github pages and jekyll. However, it became appartent that I needed to develop a way to see my changes while I was making edits to my posts.

A typical development cycle is to install jekyll on your workstation and run it locally. I typically like to keep my development free of installed packages. I also tend to hop from machine to machine and from project to project. My common practice is to create an single entrypoint in the project to boostrap everything a contributor would need to start coding right away.

  1. Clone the repository
  2. Run the entrypoint script (in this case Make)
  3. Start coding

As a bonus, this is a fun little meta post on how I finally getting started on a project rather than thinking about starting a project.

Running jekyll in a container

Docker hub provided an image jekyll/jekyll that you can use to generate and serve files from your project.

docker run -p 4000:4000 jekyll/jekyll jekyll serve

Since I didn’t want to remember that command I wrote a small docker-compose file to simplify my development environment.

version: "3"

    image: "jekyll/jekyll:builder"
      - "4000:4000"
      - ./:/srv/jekyll
      "JEKYLL_ENV": "development"
      - jekyll
      - serve

Running the command docker-compose up will start the services and you should see the following output in your terminal:

ʕ •ᴥ•ʔ docker-compose up
Starting alexjpazgithubcom_jekyll_1 ... done

jekyll_1  |  Auto-regeneration: enabled for '/srv/jekyll'
jekyll_1  |     Server address:
jekyll_1  |   Server running... press ctrl-c to stop.

You can then open your browser to http://localhost:4000 and you should see your generated site!

Other goodies

Typically with web frameworks such as webpack and command-line tools like entr there is the concept of “live reloading” or reloading the application when there is changes made to a project.

Doing a quick search I landed on livejs and including this in my layouts for jekyll

<script type="text/javascript" src="http://livejs.com/live.js"></script>

What is next?

I’m going to try and keep writing and hopefully I start improving my writing skills. I’m hoping to start another article about creating a game in the browser or pico-8.
