It's a platform depicting personal expirience/skills in graph mode

Etog

It's my personal blog "Experience to Graph" or short - "Etog" (there’s a small wordplay here, as the abbreviation is like “Resume” in Russian). Here I summarize some of my projects, completed courses or finished books, and try to share my experience and knowledge. This is my attempt to try new or interesting technologies on something more tangible than artificial projects.

The basis of the project is:

• Phoenix
• Phoenix LiveView
• Graph database Node4j

Development

To install elixir

• MacOS: brew update && brew install elixir (or follow the instructions https://elixir-lang.org/install.html)

To install Neo4j

• Check docs here

To start your Phoenix server:

• Install dependencies with mix deps.get
• Install Node.js dependencies with cd assets && npm install
• Install Stylelint cd assets && npm install -g stylelint prettier eslint
• Install Lefthook for git hooks:
  • brew install Arkweid/lefthook/lefthook https://github.com/Arkweid/lefthook
  • lefthook install && lefthook run pre-commit
• Load ENV variables source config/.env
• Start Phoenix endpoint with mix phx.server

To add translations:

• mix gettext.extract && mix gettext.merge priv/gettext && mix gettext.merge priv/gettext --locale LOCALE

Now you can visit localhost:4000 from your browser.

Build

To build a release you need a docker container. Build it (only for first release):

• docker build -t etog:latest .

Build a full release:

• docker run -v $(pwd):/opt/app --rm -it etog:latest /opt/app/bin/build

Or build an upgrade release:

• docker run -v $(pwd):/opt/app -e RELEASE_TYPE=upgrade --rm -it etog:latest /opt/app/bin/build

Deploy

To start the release you have built:

• Extract the release in releases/VERSION directly: tar xvf etog-VERSION.tar.gz
• Update a symlink and restart container: cd ~/apps/etog && rm current && ln -s releases/VERSION current && cd ~/docker && docker-compose restart etog

To upgrade a previous release:

• Copy the new release to ~/apps/etog/releases/VERSION and rename it to etog.tar.gz
• Hot reload docker exec -ti etog bach -c "./bin/etog upgrade VERSION"

Useful commands:

• Start a shell, like 'iex -S mix' _build/prod/rel/etog/bin/etog console
• Start in the foreground, like 'mix run --no-halt' _build/prod/rel/etog/bin/etog foreground
• Start in the background, must be stopped with the 'stop' command _build/prod/rel/etog/bin/etog start
• Connects a local shell to the running node _build/prod/rel/etog/bin/etog remote_console
• Connects directly to the running node's console _build/prod/rel/etog/bin/etog attach
• Show a complete listing of commands and their use _build/prod/rel/etog/bin/etog help
