Setup a Loomio development environment

A step by step guide for people wanting to install Loomio on their personal computer so they can fix bugs and write features.

There are 3 parts to this document: MacOS X system setup, Ubuntu system setup, and Application setup. You'll need to complete one of the system setups, and then the application setup after that.

MacOS X system setup

First install homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

You then need to install Command Line Tools for XCode from https://developer.apple.com/downloads.

With that done, use Homebrew to install Git and PostgreSQL

brew install git postgresql pkgconfig redis
brew install ImageMagick --with-perl
brew services start postgresql
brew services start redis

And that's it. You can jump to 'Install ruby'

Ubuntu system setup

sudo apt-get update
sudo apt-get install postgresql postgresql-contrib build-essential \
                     libssl-dev libreadline-dev zlib1g-dev \
                     libpq-dev libffi-dev libmagickwand-dev \
                     imagemagick python3 redis

Install ruby

I recommend that you install ruby via rbenv, this gives you the flexibility required to install and switch between various versions of ruby.

Follow the installation steps for rbenv from https://github.com/sstephenson/rbenv#installation.

Then install ruby-build like so:

mkdir -p "$(rbenv root)"/plugins
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build

When a new version of ruby is released, you can update ruby-build with

cd "$(rbenv root)"/plugins/ruby-build && git pull

At the time of writing 3.2.4 is the version of ruby that Loomio uses. To check what the current version required is, see .ruby-version

rbenv install 3.2.4
gem install bundler

Install node

You'll need Node.js and I recommend you use nvm to install it. Just run:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.1/install.sh | bash

You'll need to restart your terminal, then run:

nvm install 14
nvm alias default 14

Fork and clone the Loomio git repo

I recommend you visit https://github.com/loomio/loomio then click "Fork" to create your own loomio repository to work from. Then clone that repo to your local computer:

cd ~/projects # or wherever you like to keep your code
git clone git@github.com:YOURUSERNAME/loomio.git && cd loomio

Install ruby and node dependencies

From you freshly checked out Loomio repo:

bundle install
cd vue; npm install && cd ..

Create database.yml

cp config/database.example.yml config/database.yml

On Linux you'll need to create a postgres user with the same name as your Linux user account. This is not required on MacOS as it's automatic.

sudo postgres -c 'createuser -P --superuser <username>'

Setup the Loomio database and schema

createdb loomio_development
rake db:setup

Launch rails and npm serve

In one terminal run

rails s

In the another run

cd vue
npm run serve

You can view Loomio in your browser by visiting http://localhost:8080.

To view Loomio's features and changes to your source code, visit any of the dev routes listed at http://localhost:8080/dev/ (be sure to include the trailing slash). A good place to is http://localhost:8080/dev/setup_group.

Other things to know

Rails stuff

  • sometimes rails s and similar commands will fail. Try with bundle exec rails s and that can help.
  • rails c will bring up a rails console
  • 'rspec' will run the rails tests

Having trouble?

Let us know in the product development group on Loomio.
