A simple javascript based binary encoding scheme for a message interface

• The Message string is made up of segments
• Each segment is separated by a character '/'
• First segment is for the size of headers from 00 to 63
• Next comes headers one by one with key-values separated by '/'
• Last comes the payload
• Message string is converted into binary Array Buffer
• All segments are URLEncoded in order to escape '/' character in the content

• Binary array buffer is converted into message string
• message string is split into segments by '/'
• First segment (header size) is used to run a loop through next segments and get all headers
• Last segment is fetched as payload
• All segments are URLDecoded to bring back any escaped character

• It's assumed that the initial state of a message is always { headers: {}, payload: '' }
• System tries to return to the initial state when there's a erroneous deviation in message input structure

• MessageCodec.test.js contains basic tests without help of any testing tool
• node MessageCodec.test.js to run the tests
