Using as module

var onEnd = function (result) {
  if (result.error) {
    console.log(result.error)
    return
  }
  console.log("done")
  console.log(result.latestTime)
}

var downloadEmailAttachments = require('email-attachments');
downloadEmailAttachments({
  invalidChars: /[^A-Z]/g, //Regex of Characters that are invalid and will be replaced by X
  account: '"[email protected]":[email protected]:123', // all options and params besides account are optional
  directory: './files',
  filenameTemplate: '{day}-{filename}',
  filenameFilter: /.xlsx?$/,
  timeout: 3000,
  log: {warn: console.warn, debug: console.info, error, console.error, info: console.info },
  since: '2015-01-12',
  lastSyncIds: ['234', '234', '5345'] // ids already dowloaded and ignored, helpful because since is only supporting dates without time
  attachmentHandler: function (attachmentData, callback, errorCB) {
    console.log(attachmentData)
    callback()
  }
}, onEnd)

Options

You have to pass an imap account with password, the format is:

username:password@host:port

• username If username contains @ or :, put it in quotes, e.g. `"[email protected]":[email protected]
• password If password contains @ or :, put it in quotes, e.g. `joe:"123:@456"@example.com
• host This is the imap domain
• port Optional, defaults to 993

--directory / directory

Optional. Defaults to ./

Directory where attachments shall be downloaded to.

--filename-template / filenameTemplate

Optional. Defaults to {filename}

Filenames the attachments shall be saved as. Using / will create subfolders. The following placeholders are available

• {filename}, e.g. data.xls
• {basename}, e.g. data
• {extension}, e.g. xls
• {day}, e.g. 2015-01-01
• {recipientAddress}, e.g. [email protected]
• {senderAddress}, e.g. [email protected]
• {id}, unique content ID, e.g. c361f45d-98b6-9b18-96ac-f66aee2cb760
• {nr}, starts at 1 and increments for every stored file.

--filename-filter / filenameFilter

Optional

Pass a regular expression, only attachments matching it will be downloaded.

--timeout / timeout

Optional, defaults to 10000

Timeout in millisecond to wait for data from the imap server until closing the connection.

--since / since

Optional. Defaults to today's date in YYYY-MM-DD format

Local setup

git clone [email protected]:gr2m/download-email-attachments.git
cd download-email-attachments
npm install

Run all tests

npm test

Note: There is no full stack test yet, because of the complexity of stubbing an imap server. If someone could help here, that'd be much appreciated! Ping me
