Parse a mime tree, no magic included. This is supposed to be a "low level" mime parsing module. No magic is performed on the data (eg. no joining HTML parts etc.). All body data is emitted out as Typed Arrays, so no need to perform any base64 or quoted printable decoding by yourself. Text parts are decoded to UTF-8 if needed.

Usage

npm install --save emailjs-mime-parser
import parse from 'emailjs-mime-parser'

parse(String) -> MimeNode

MimeNode

A MimeNode represents a MIME tree.

MimeNode
|
+----> childNodes -> [MimeNode]
+----> content -> Uint8Array
+----> bodyStructure -> String
MimeNode.childNodes -> [MimeNode]

The child MIME nodes are stored in the childNodes array.

MimeNode.content -> Uint8Array

The content of the specific node is stored in this.content as Uint8Array. All body data is emitted as Typed Arrays, so no need to perform any base64 or quoted printable decoding by yourself. Text parts are decoded to UTF-8 if needed.

message/rfc822 is automatically parsed if the mime part does not have a Content-Disposition: attachment header, otherwise it will be emitted as a regular attachment (as one long Uint8Array value).

MimeNode.bodyStructure -> String

Bodystructure is the original raw message stripped of bodies and multipart preambles. MIME stores like to store the bodystructure of MIME content in raw (loss-less) form, to later run through a MIME parser to answer IMAP or WebDAV type queries.
