Microservices Development Cookbook

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Open the newly created service object in the app/services/attachments_service.rb file and move the responsibility for uploading the file to the AttachmentsService#upload method."

A block of code is set as follows:

class AttachmentsService  def upload(message_id, user_id, file_name, data, media_type)    message = Message.find_by!(message_id, user_id: user_id)    file = StorageBucket.files.create(      key:  file_name,      body: StringIO.new(Base64.decode64(data), 'rb'),      public: true    )
