A Rails application generator from Platanus, inspired by Suspenders.

You have to install Potassium globally:

$ gem install potassium

Use the potassium create command to create a new project:

$ potassium create <project-name>

Please note:

1. Potassium will perform a version check before running to ensure that you are using the latest potassium.
2. If you feel that it's too slow, you may need to update rubygems: gem update --system.
3. Potassium uses node under the hood, so a check will also be performed to ensure you are running the supported version.

In case you want to use the Platanus Configuration you should use the following command:

$ potassium create <project-name> --platanus-config

This will create a project with the following configuration:

1. database: 'postgresql'
2. local: 'es-CL'
3. email_service: 'sendgrid'
4. devise: true
5. devise-user-model: true
6. admin: true
7. vue_admin: true
8. pundit: true
9. api: true
10. storage: 'shrine'
11. heroku: true
12. background_processor: true
13. draper: true
14. schedule: true
15. sentry: true
16. front_end_vite: true
17. google_tag_manager: true
18. test: true
19. spring: true

The remaining question will be asked as usual.

If you cloned this repository and are running the gem using the bin script (potassium/bin/potassium create), take careful note of the gem versions that are used. Sometimes the local Rails version is used instead of the one specified in the gemspec. Remove your local Gemfile.lock after pulling from the repository to help prevent these issues.

Use the potassium install command to add a recipe to a project:

$ potassium install devise

You can force an already installed recipe by passing the --force argument

$ potassium install devise --force

You can run the command on its own to view all the available recipes and select one:

$ potassium install

Potassium Rails apps includes the following gems and technologies:

• dotenv for loading environmental variables in development
• Yarn for frontend assets packages
• EditorConfig for keeping all our editor configurations the same
• pry and pry-byebug for a less painful debugging experience
• RSpec for unit and integration testing
• FactoryBot for test factories
• Guard for continuous testing and other watch-related tasks
• AWS-SDK for file uploads, sdks, etc and because we use AWS
• Puma to serve HTTP requests
• Rack Timeout to abort requests that are taking too long
• Tzinfo-Data for updating timezone information
• Faker for creating development data
• Scout for monitoring performance
• Mjml for mails style
• Bullet to identify eager loading (N+1 queries)

The following optional integrations are also added:

• PostgreSQL or MySQL for the database
• Devise for authentication
• ActiveAdmin for admin interfaces
• ActiveAdminAddons for some help with ActiveAdmin
• Pundit for role-based authorization
• Sidekiq a simple, efficient background processing for Ruby
• Sidekiq-scheduler to run scheduled processes
• Mailing configuration for AWS SES and Sendgrid with recipient interceptor support
• Sentry to monitor exceptions and errors
• Vue.js or Angular 2 for frontend development
• Google Tag Manager for analytics
• Creates the Github repository of your choice for the project. A local git repository will always be created.

A few more things are added to the project:

• A low database connection pool limit
• Setup continuous integration in CircleCI to run tests
• A bin/setup script to setup things on a newly cloned project
• A bin/cibuild script to run continuous integration build on CI
• A db:fake_data:load rake task to load fake data for development

The optional API support includes:

• Responders for dry-ing our api controllers
• Versionist for some flexible api versioning
• ActiveModel::Serializers for record serialization
• Simple Token Authentication for stateless API authentication

When you choose to deploy to heroku a few extra things are added for the project.

• Adds a Procfile to define the processes to run in heroku
• Setup continuous integration using docker and herokuish to maintain better parity between testing and production environments
• Adds a bin/release file with the release phase script to run specific tasks before the app is deployed completely, for example rails db:migrate:with_data
• Adds a .buildpacks file with the default buildpacks to use. It use the following buildpacks:

Also the heroku applications are created

• Creates a staging and production applications
• Creates a pipeline and assign the above application to the staging and production stages
• Setup initial configuration variables
• Set the application buildpack to the multi-buildpack

You'll need to manually

• Connect the pipeline with the github repository
• Assign a branch to each stage for auto deployments
• Enable deploy after CI pass

In order to CicleCI start building the project on each push you need tell circle ci. Go to https://circleci.com/add-projects, choose the repository from the list and hit Build Project

In order to enable code linting via CircleCI and ReviewDog, you need to activate the Only build pull requests option under the Advanced settings section for your project.

This is useful when you are adding new recipes to Potassium, and you want to use the potassium create command, to check the new functionality without pain. To achieve this you need to run, In the Potassium's root path, the bin/potassium_test create instead of potassium create command. This command, will do the same as potassium create but first:

• Will drop any existent database of the test app
• Will remove the directory containing a previous version of the test app

It's important to remember that bin/potassium_test create:

• Does not receive an app_path param. It always creates the test project inside /tmp/dummy_app
• Can receive the same options as potassium create
• Runs with options with a default value. This is to avoid the "asking part" of the creation process. You need to enable what you want to test like this: $ bin/potassium_test create --clockwork

On master branch.

1. Change VERSION in lib/potassium/version.rb
2. Change Unreleased title to current version in CHANGELOG.md
3. Commit new release. For example: Releasing v6.3.0
4. Create tag. For example: git tag v6.3.0
5. Push tag: git push origin v6.3.0
