Local development

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

Dependencies:

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

  1. 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.

  1. To run the test suite in docker:

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