Heliodor is server-less database management tool


Add this line to your application's Gemfile:

gem 'heliodor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install heliodor


Next example creates new database file, table inside of it and inserts value

require 'heliodor'
db = Heliodor::DB.new './example.db'
  .query('Users') # Perform query on table 'users'
  .ensure         # Ensure that this table exists - if it does not, create it
  .insert(first_name: 'Vasya', last_name: 'Pupkin', age: 20) # Insert data into table
  .write  # Write data
  .finish # Finish query - executes all statements

# Resulting table will be returned after finishing query
