Services Communication Design

TL;DR The plan is to use protobuf for the format. Message calls should be made with gRPC when the client wants a response. High level messages should also be published to the bus. Message calls (events) that don't require a response can just be published to the bus.

There are 3 parts to consider:

Messaging format
Client calls that require a response - RPC
Publishing events - BUS

Messaging Format

The message format must be statically typed, binary, good adoption and have RPC integration.

# Gemfile

gem 'simple_form'

Further customization

bundle open simple_form

<!-- app/view/blogs/_form.html.erb -->

<%= simple_form_for @blog, :html => { :class => 'form-horizontal' } do |f| %>

Customization

<%= f.input :state, :collection => ['SA', 'WA'] %>

<%= f.input :state,
            :as => :radio_buttons,
            :collection => ['SA', 'WA'],

Config

# config/initializers/simple_form.rb

SimpleForm.setup do |config|
  config.wrappers :default,
                  :class => 'input',
                  :hint_class => 'field_with_hint',
                  :error_class => 'field_with_errors' do |b|

	swift code exemplifying sandy metz style duck types
	Sure, here's an example of a Swift code that uses duck typing, in a style similar to that of Sandi Metz:

	swift
	Copy code
	protocol Quackable {
	func quack() -> String
	}

	// TL;DR: look at this cool thing in swift
	let ibsTags = try ibsTagRecords().reduce(into: [Int64: [Int64]]()) {

	// this line here
	$0[$1.ibsID, default: []].append($1.tagID)

	}

	// V1 original

	class RawOSMDataTests: QuickSpec {
	override func spec() {
	context("given a RawOSMData") {
	var subject: () -> RawOSMData? = { return nil }

	describe(".decode") {
	var json: String? = ""
	afterEach { json = nil }

	beforeEach {

	#!/usr/bin/env bash

	set -e
