Starter Kit Application

This is a starter Rails application with everything you need to properly bootstrap a useful Rails application. This is a fully self-contained application with backend stack.

Prerequisites

You need to have the following installed before you can run this application:

• Refer to the .tool-versions file for current Ruby / NodeJS versions.
• Docker for Mac

asdf is the recommended version manager for Ruby.

Installing pg gem on macOS

If you're trying to install the postgresql gem pg and it is failing with the following error message:

Installing pg 1.2.3 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    current directory: ~/.rbenv/versions/3.0.0/lib/ruby/gems/3.0.0/gems/pg-1.2.3/ext
~/.rbenv/versions/3.0.0/bin/ruby -I ~/.rbenv/versions/3.0.0/lib/ruby/3.0.0 -r ./siteconf20210125-97201-pycpo.rb extconf.rb
checking for pg_config... no
No pg_config... trying anyway. If building fails, please try again with
 --with-pg-config=/path/to/pg_config
checking for libpq-fe.h... no
Can't find the 'libpq-fe.h header

The following helped me resolve the issue without having to install the entire postgresql as recommended in the stop Stack Overflow post (already using it in a Docker container):

brew install libpq
gem install pg -- --with-pg-config=/usr/local/opt/libpq/bin/pg_config

Backend

Backend services defined in the docker-compose.yml are:

• Postgres 15.3
• Redis 7.2
• Memcached 1.6

Docker scripts

The backed services are configured in the docker-compose.yml file. These services are controlled via some convenience scripts in ./bin/docker:

• ./bin/up -> Install docker images and start the services.
• ./bin/stop -> Stop all the services.
• ./bin/watch -> Monitor all services in real-time.
• ./bin/teardown -> Remove all docker containers and images.

Setup

• Start all the docker services.
• Run the provided setup script:

./bin/setup

• Seed the database:

rake development:truncate_and_seed

• Start the app:

foreman start

Configuration

• You can override environment settings in the .env file.

Run the application

• Start the application:

foreman start

• Navigate to http://localhost:3000
• Login using the default user credentials:
  • Email: jim@example.com
  • Password: Changeme1!

Resetting data

• Run the provided rake task to prepare a clean dataset:

rake development:truncate_and_seed

Running tests

• To run the test suite simply run:

rspec

• You can also run guard for TDD-style testing:

guard

Sample data

• There are 3 sample data files provided for general use / experimentation:

• data/credit-cards.json -> Sample JSON credit card data created at generatedata.com

• data/moviedata.json -> Sample JSON data file from the AWS DynamoDB tutorial
