A simple API for books.

Installation

1. Fork and clone this repository.

2. Change into the new directory.

3. Install dependencies with bundle install.

4. Create a .env for sensitive settings (touch .env).

5. Generate new different secrets for both development and test environments (bundle exec rake secret).

6. Store them in .env with keys SECRET_KEY_BASE_<DEVELOPMENT|TEST> respectively.

7. Create a database with bundle exec rake db:create.

8. Create a database schema with bundle exec rake db:migrate.

9. Add data to the database with bundle exec rake db:seed db:examples.

10. Run the HTTP server with bundle exec rails server or bin/rails server.

Structure

library-api-guide follows the standard project structure for Rails 4.

User authentication is built-in.

curl command scripts are stored in scripts with names that correspond to API actions.

Tasks

• rake routes lists the endpoints available in your API.
• rake test runs automated tests.
• rails console opens a REPL that pre-loads the API.
• rails db opens your database client and loads the correct database.
• rails server starts the API.
• scripts/*.sh run various curl commands to test the API. See below.
