Local development

The most common way to run a development version of the application is run with local dependencies.

Dependencies:

• Ruby
• Rails
• PostgreSQL
• NodeJS
• Gecko driver (for running Selenium tests)

We recommend using RBenv to manage Ruby versions.

We recommend using nvm to manage NodeJS versions.

Pre-setup installation

1. Install PostgreSQL

   macOS:

   brew install postgresql
   brew services start postgresql
   

   Linux (Debian):

   sudo apt install -y postgresql postgresql-contrib libpq-dev
   sudo systemctl start postgresql
   

2. Create a Postgres user

   sudo su - postgres -c "createuser <username> -s -P"
   

3. Install RBenv and Ruby-build

   macOS:

   brew install rbenv
   rbenv init
   mkdir -p ~/.rbenv/plugins
   git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
   

   Linux (Debian):

   sudo apt install -y rbenv git
   rbenv init
   echo 'eval "$(rbenv init -)"' >> ~/.bashrc
   mkdir -p ~/.rbenv/plugins
   git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
   

4. Install Ruby and Bundler

   rbenv install 3.1.4
   rbenv global 3.1.4
   source ~/.bashrc
   gem install bundler
   

5. Install JavaScript dependencies

   Note that we currently use node v16, which is no longer the latest LTS version so you will need to specify the version number when installing

   macOS (using nvm):

   nvm install 20
   nvm use 20
   brew install yarn
   

   or you could run it without specifying the version and it should use the version from .nvmrc

   nvm install
   nvm use
   brew install yarn
   

   Linux (Debian):

   curl -sL https://deb.nodesource.com/setup_20.x | sudo bash -
   sudo apt -y install nodejs
   mkdir -p ~/.npm-packages
   npm config set prefix ~/.npm-packages
   echo 'NPM_PACKAGES="~/.npm-packages"' >> ~/.bashrc
   echo 'export PATH="$PATH:$NPM_PACKAGES/bin"' >> ~/.bashrc
   source ~/.bashrc
   npm install --location=global yarn
   

6. (For running tests) Install Gecko Driver

   Linux (Debian):

   wget https://github.com/mozilla/geckodriver/releases/download/v0.31.0/geckodriver-v0.31.0-linux64.tar.gz
   tar -xvzf geckodriver-v0.31.0-linux64.tar.gz
   rm geckodriver-v0.31.0-linux64.tar.gz
   chmod +x geckodriver
   sudo mv geckodriver /usr/local/bin/
   

Also ensure you have firefox installed

7. Clone the repo

   git clone https://github.com/communitiesuk/submit-social-housing-lettings-and-sales-data.git
   

Application setup

1. Copy the .env.example to .env and replace the database credentials with your local postgres user credentials.

2. Install the dependencies:

   bundle install && yarn install
   

3. Create the database & run migrations:

   bundle exec rake db:create db:migrate
   

4. Seed the database if required:

   bundle exec rake db:seed
   

Running Locally

Application

Start the dev servers

a. Using Foreman:

./bin/dev

b. Individually:

Rails:

bundle exec rails s

JavaScript (for hot reloading):

yarn build --mode=development --watch

If you’re not modifying front end assets you can bundle them as a one off task:

yarn build --mode=development

Development mode will target the latest versions of Chrome, Firefox and Safari for transpilation while production mode will target older browsers.

The Rails server will start on http://localhost:3000.

Tests

bundle exec rspec

Or to run individual tests / files use your IDE

Formatting

• yarn prettier . --write for scss, yml, md, and json files
• yarn standard --fix for js files

Linting

bundle exec rake lint

Using Docker

1. Build the image:

   docker-compose build
   

2. Run the database migrations:

   docker-compose run --rm app /bin/bash -c 'rake db:migrate'
   

3. Seed the database if required:

   docker-compose run --rm app /bin/bash -c 'rake db:seed'
   

4. To be able to debug with Pry run the app using:

   docker-compose run --service-ports app
   

If this is not needed you can run docker-compose up as normal

The Rails server will start on http://localhost:8080.

5. To run the test suite in docker:

   docker-compose run --rm app /bin/bash -c ' RAILS_ENV=test rspec'
