SimpleDB Transport for Winston

The winston-simpledb module allows you to log your winston messages to Amazon's SimpleDB.

var SimpleDB = require('winston-simpledb').SimpleDB;

winston.add(winston.transports.SimpleDB, {
    // for andychilton
    accessKeyId : '...',
    secretAccessKey : '...',
    awsAccountId : 'xxxx-xxxx-xxxx',
    domainName : 'log',
    region : amazon.US_EAST_1,
    itemName : 'uuid',


  $ npm install winston-simpledb


winston-simpledb is just like any other transport for winston. When adding it to winston, it takes some options so that it knows where to log to SimpleDB.

The SimpleDB transport takes the following options:

accessKeyId     : your AWS access key id
secretAccessKey : your AWS secret access key
awsAccountId    : your AWS access id (of the form 'xxxx-xxxx-xxxx')
region          : the region where the domain is hosted (of the form amazon.US_EAST_1)
domainName      : the domain name to log to, or a function to generate the domain name
itemName        : the type of itemName to use or a function to generate the item name

AWS Credentials

All of these options are values that you can find from your Amazon Web Services account: 'accessKeyId', 'secretAccessKey' and 'awsAccountId'.


This is the region in which your domain is located. For example you need to pass it one of the amazon.* constants such as amazon.US_EAST_1 or amazon.EU_WEST_1. See 'awssum' for more details.


The domainName provided is the one where you want your messages logged. As well as providing a string, you may instead provide a function which returns a string. This gives you the ability to dynamically change which domain to log to.

Valid domainName options are:

a string    -> the domain name is this literal string
a function  -> the string that this function returns


The itemName option you provide determines how the itemName is generated when logging to SimpleDB. You may provide a string which is a predefined generator (such as 'uuid', 'epoch' or 'timestamp') or a function which returns an itemName.

Valid itemName options are:

'uuid'      -> '75f38e1c-1bc6-4854-b3e2-9e6b65e9d012'
'epoch'     -> 1321751212043
'timestamp' -> '2011-11-20T01:06:52.043Z'
function    -> (a string that the function returns)
