Yarn link packages dependencies

If you have a react project that depends on a package and you need to update your package, keep reading! This article will not talk about example folder created with create-react-library.

We are building a simple React App that will have only one component that take a string as props and display the reversed string. Then adding a new Component that take a sentence and reverse the words inside the sentence.

Not very usefull but easy example to get started with dependencies.

module A
  def method_a
    puts 'instance method A'
  end

  class_methods do
    def method_a
      puts 'class method A'
    end
  end

test_hash = {
  a: 1,
  b: 2,
  c: {
    d: 4,
    e: 5,
    a: 1

SSL Certificate With Gandi

Generate Signing Certicate Request

With current private key (preferred for Certificate Pinning):

$ openssl req -new -key example.com.key > example.com.csr 
You are about to be asked to enter information that will be incorporated
into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN.
