I am trying to create a JS script to open and view Eml file. But till now I am stuck and with no way to go further. Can someone give me some directions. I was planning to post back my findings here with code so others can benefit too.
Opening and viewing Eml files in Html

The first step is to load the EML file either as a String or as a Stream. A EML file should look like this:
Date: Wed, 29 Jan 2014 11:10:06 +0100
To: "Foo Bar" <[email protected]>
From: Online Shop <[email protected]>
Subject: Winter promotions
Content-Type: text/plain; charset=utf-8
Some Content
If you are looking to parse it yourself you have to look for keys like this:
/[\n\r]+[\-a-zA-Z]+:/ (a newline followed by a word with no spaces and a colon)
Everything after the colon and before the next key will become the value for that key.
- However bear in mind that keys will repeat and the order they appear matters,
- Some keys are optional and most eml you will find nowadays have plenty of custom Keys,
- You should double check the values as some will need a decode algorithm to be usable.
