Sinatra App Template

Lightweight web framework codebase. Just clone and develop on it.

Tech component: Rack+Sinatra+Sequel and default use Postgresql database.

Add rails-like migration command line helpers.

Find helpful rake tasks

rake or rake -T

Run server & develop

rake server:run

Production Server & deploy

APP_ENV=production bundle exec rake server:run

you can also use docker

docker built -t <what your docker image label> .

Custom server & database

You can use DSL to config Key:Value , then you application just use.

Config::Default.configure do\n set :app_env, ENV.fetch('APP_ENV'){ 'development' }\n set :bind, ENV.fetch('HOST') { '0.0.0.0' }\n set :port, ENV.fetch('PORT') { 3000 }\n set :secrets, ENV.fetch('SECRETS') { 'YOU CANNOT GUESS ME' }\n set :max_threads, ENV.fetch('MAX_THREADS') { 5 }\n\n set :database_url, ENV['DATABASE_URL']\nend\n\nConfig::Development.configure do \n set :database_url, 'ENV['DATABASE_URL']'\nend\n\nConfig::Test.configure do \n set :database_url, ENV['DATABASE_URL']\nend\n\nConfig::Production.configure do \n # set :database_url, ENV['DATABASE_URL']\nend\n

They have an inheritance relationship

Development < Default\nTest < Default\nProduction < Default\n

In your code, just use Config directly. core/bootstrap do a work that loaded all necessery mods before your code.

Config.current # current env configuration\n\nConfig::Development.database_url\n\nConfig::Development\n\nConfig::Development.database_url\n

You can also create your own Config for your single Application:

class MyConfig < Config::Base\n\nend\n\nMyConfig.configure do \n # set :database_url, ENV['DATABASE_URL']\nend\n\n

Mount different Sinatra web application

Edit config.ru

Lark also is Rack application. We can use Rack middlewares.

require_relative './cores/bootstrap'\nBootstrap.rack \n\n# you can load Rack middleware here\n\n# mount applications\nrequire 'controllers/root_controller'\n# routers(handy config)\nmap '/' do\n run RootController \nend\n

Base

bases directory are use for Application Base Class.

You can make different Configured Sinatra Application class here, then your application/controller just inherit the Base Class to create Application.

It will share Config, and make less code.

# Sinatra Doc http://sinatrarb.com/intro.html\nrequire 'sinatra/base'\nrequire 'json'\n\nclass BaseController < Sinatra::Base\n # Inject config\n\n # Config & register Sinatra Extensions\n\n # Rewrite Views dir\n settings.views = File.expand_path(File.join($PROJECT_DIR, 'views'))\n\n configure :development do\n require 'sinatra/reloader'\n register Sinatra::Reloader\n end\n\n # mount Sinatra Helpers\n\n # mount Sinatra middlewares\n\nend\n\n\n# Share Configuration\n\nclass MyPageServer < BaseController\nend\n\nclass MyApiServer < BaseController\nend\n\n

ORM & Tools

Provide rails-like rake task help you build app quickly.

rake db:check # Checking for current migrations\nrake db:connect # Connect database\nrake db:console # Database Console\nrake db:create[database_name] # Create database\nrake db:create_migration[name] # Create a migration\nrake db:drop[database_name] # Drop database\nrake db:ls # List database tables\nrake db:migrate[version] # Run migrations\nrake db:rollback[version] # Rollback to migration\nrake db:version # Prints current schema version\nrake list # List all tasks\nrake seed:all # Seed: run all seeds\nrake seed:run[seed_name] # Seed: run seed\nrake server:run # Run server\nrake test # Run tests\n

Bootstrap & Load orders

For Rake

require_relative './cores/bootstrap'\nBootstrap.rake\n

It will auto load files make sure rake task can work.

In rake we can use Config.current to read configuration.

DB also available.

For Rack/Applications

In the same way

require_relative './cores/bootstrap'\nBootstrap.rack\n# OR\n# Bootstrap.apps\n

It will autoload all dep mods. Share with a context.

Change load orders

cores/bootstrap.rb defines different load orders, you can change.
