Supported platforms

J1 is supported on all current x64-based OS:

• Windows 10, build >= 1903
• Windows WSL 2
• Linux, kernel version >= 4.15 (e.g. Ubuntu 18.x LTS)
• OSX, version >= 10.10.5 (Yosemite)

Note that 32-bit versions (x32) are generally not supported for all platforms.

Development languages and tools

To run the Development System for J1 Theme, the following languages and tools expected to be in place with your OS:

• Ruby language, version v3
• Javascript (NodeJS), version >= 18
• NPM, version >= 8.5
• YARN, version >= 1.22
• Git, version >= 2.29

<1> required only for full Jupyter Notebook support

Note: More current or older versions may work, but not tested.

Development packages

For some of the componentsJ1 is using, a working C/C++ development environment is needed to compile platform-specific libraries. Ensure that all dev packages are installed for your OS (Linux, OSX, or Windows).

Development packages for Windows

For Ruby on Windows, a installation using RubyInstaller is recommended. A current Ruby of version 3.1 is available at the RubyInstaller site.

Note, to automatically install a development environment for Ruby on Windows, a x64 version of Ruby should be installed that is already bundled with a DEVKIT (MSYS2 toolchain).

Development packages on Linux (Ubuntu)

In order to install all required development components on e.g. Ubuntu you run:

sudo apt-get -y install \
gcc g++ make \
autoconf bison build-essential \
libssl-dev \
libyaml-dev \
libreadline-dev \
zlib1g-dev \
libncurses5-dev \
libffi-dev \
libgdbm-dev

To install the required languages and tools, if not already in place, the following commands can be used to do so:

sudo apt-get -y install \
curl \
git-all \
nodejs \
ruby

Additionally, for Ruby and NodeJS the dev-packages are to be installed to make all header files available for a working C/C++ development environment:

sudo apt-get -y install \
nodejs-dev \
ruby-dev

Note that priviliged (administrative) user rights are needed to install system-wide software packages for the OS.

Development packages on OSX

For all OSX system, the installation of the Apple Developer Tools (XCode) is expected. Development tools like Ruby, NodeJS, or the bash comes with the OS are not recommended to use. Most of the software comes in quite old versions and therefor unusable for J1 development.

To install recommended versions, the easiest way to install the missing software is Homebrew. A lot of helpful information how to manage package installations using Homebrew can be found on the internet.

Beside the base installation of the recommend tools, all other recommendations for Linux systems are for OSX the same.

Upgrades needed for all platforms

If Ruby and NodeJS are in place, some packeages are to be upgraded to more current versions. Install all packages system-wide with their respective product installation pathes.

Upgrades needed for Ruby <= v2.7

Install latest bundler for Ruby:

  gem install bundler --no-document

Install latest RubyGems for Ruby:

  gem install rubygems-update --no-document
  update_rubygems --no-document
  gem update --system

Upgrades needed for NodeJS

NodeJS comes with NPM pre-installed. The native CLI for the NodeJS package management is npm. Besides npm there's another quite handy CLI for NPM available: Yarn.

The CLI yarn is developed at Facebook and can be used as a replacement for npm. From a top-level perspective, both package management clients behave pretty much the same. The syntax yarn uses is shorter in writing, making the command-line look a bit more natural. Therefore, we prefer to use yarn.

NOTE: Yarn adds some additional features to the NodeJS package management implemented for the needs at Facebook. Regarding the J1 development system, those add-ons are neither needed nor used.

Install latest NPM and Yarn packages for NodeJS:

  npm install -g npm@latest
  npm install -g yarn@latest

Setting up the project

Running the J1 Theme project is very simple:

• Downlad the repo
• Setup the project
• Run and develop the buildin starter web

Checkout the Repo

The repo for the J1 Theme development system is published on Github. You can get it from Github by cloning the repository using git:

git clone https://github.com/jekyll-one-org/j1-template.git

The repo gets written to folder j1-template. Have a look and browse the folder. You'll see a structure like this:

j1 development repo

  ├──── .git
  │    └─── packages
  │         ├──  100_theme_css
  │         ├──  200_theme_js

  │         ├──  400_theme_site

J1 Theme is a so-called multi-package project, a Monorepo managed by Lerna. A Monorepo is a strategy where multiple (sub-)projects are stored in a single repository instead of putting them into individual repositories.

All development tasks are defined as NPM scripts with the top-level project config file package.json. For each package, package-level config files are used having the same name package.json to manage specific tasks like the generation of CSS and JS files, or creating the buildin starter web.

All base development tasks are defined with the top-level project configuration; no need to dive into all the package-level configurations. All is managed by Lerna, based on simple top-level tasks.

Initialize the project

Initializing the project is managed by the top-level task setup. A bunch of sub-tasks are fired, all of the managed by Lerna.

Let's start ...

yarn setup

Because a lot of sub-tasks getting started for a (first) setup, see below the output as a summary :

The setup process will take a while - typically up to ten minutes for the first run (depending on the performances of your Internet connection and your workstations power). A bunch of NPM modules and Ruby Gems are downloaded and linked for the packages part of the repo. See setup as an extended install and build process to manage an initial setup for the (Lerna) Monorepo.

Running the Starter Web

Running the buildin Starter Web for development is done like so:

yarn site

The task site does a lot for you. Whatever is necessary for a full-stack Web development. The task will put in place all needed CSS and JS components, build the content, and finally run the website in a browser.

Go, go, go ..

Finally, the J1 starter web get openend in your default browser.

Reset the Development System

To start from the beginning, you can reset the development system to the factory state. The top-level task reset does the resetting work for you and cleans up each and everything except the Git repo and the NPM modules folder node_modules stored in the project root. Both are kept untouched by a reset.

yarn reset

The cleanup runs some tasks for the root folder and in parallel sub-tasks using Lerna for all packages:

Reset development system to factory state ..
Clean up project root files ..
Remove bundle folder ..
Remove log folder ..
Remove log files ..

Clean up project packages ..

done.

Done in 11.20s.

To reset the Development System completely, delete the folder node_modules manually and start from the scratch by running the setup task again:

yarn setup

Happy Jekylling!
