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.

I'm interested in that question too. In the meantime, I suggest using mhonarc to convert (on the server) the
emlfiles tohtml. – Clément Commented Nov 20, 2017 at 2:31

Reset to default 1The 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 bee 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.
