launchpad.rb

status: WIP

Application Stack

• ruby
• roda
• parity
• launchpad swarm setup
• postgres

Coding Style

The code style of the project is RubyJS (RJS for the most intimates - :D)

The core principles are:

• use arrow functions (lambdas)
• use exports
• use brackets ( () and .() ) when defining and calling methods
• use modules not classes
• use {} instead of where you commonly use the do -- end coding style commonly used for multiline blocks

function -> { } 

module Something
  SomeFunction = -> {
    # ...
  }
end

Exports.default = Something

see more infos about RJS: https://github.com/makevoid/rjs

And remember to use RSpec and request specs

Rspec.describe do |r|
  r.specify("") {
    value.should == '123'
    # get("/"); body.should =~ /foobar/
  }
end

Modules

• search (dm ferret or elasticsearch)
• datamapper to datamapper2 (ROM)
• op_return integration and explorer

SOON

• ipfs
• tendermint

Step 1) Setup

Deploy an ethereum contract and call it

require_relative 'env'

contract = Ethereum::Contract.create file: "store.sol", client: CLIENT
address = contract.deploy_and_wait
puts "new contract: #{address}"

5.times do
  contract.transact.set "rand-#{rand 10}"
  value = contract.call.get
  puts "got value: #{value}"
end

Step 2) Configure

serverless/docker-compose.yml

services:
  app:
    image: me/my-launchpad-function1
    environment:
      - RACK_ENV=production
      - PARITY_HOST=xxx
    depends_on:
      - parity
    # ports:
    # - 9292:9292
  parity:
    image: appliedblockchain/parity-solo
    environment:
      - NETWORK=mainnet
      #- NETWORK=kovan

Step 3) Deploy

Deploy via kubernetes

docker pull me/my-launchpad-function1
docker stack deploy -c docker-compose.yml my-launchpad-stack --orchestrator=kubernetes
