An InfluxDB Node.js Client

npm install influx

Create a client instance (database not required for all methods):

var client = influx(

  //cluster configuration
  hosts : [
    {
      host : 'localhost',
      port : 8060 //optional. default 8086
    }
  ],
  // or single-host configuration
  host : 'localhost',
  port : 8086, // optional, default 8086
  username : 'dbuser',
  password : 'f4ncyp4ass',
  database : 'my_database'
});

A list of all configuration values can be found below.

You can either pass a single hostname or an array of hostnames. Node-influx uses round-robin balancing to distribute the requests across all configured hosts. When a host is unreachable, node-influx tries to resubmit the request to another host and disables the failed host for 60 seconds (timeout value is configurable). If all servers fail to respond, node-influx raises an error.

###setRequestTimeout Sets the default timeout for a request. When a request times out the host is removed from the list of available hosts and the request is resubmitted to the next configured host. The default value is null (will wait forever for a respose).

Be careful with this setting. If the value is too low, slow queries might disable all configured hosts.

setRequestTimeout( value ) { }

###setFailoverTimeout Sets the failover timeout for a host. After a host has been removed from balancing, it will be re-enabled after 60 seconds (default). You can configure the timeout value using this function.

setFailoverTimeout( value ) { }

###getHostsAvailable Returns an array of available hosts.

getHostsAvailable( ) { }

###getHostsDisabled Returns an array of disabled hosts. This can be useful to check whether a host is unresponsive or not.

getHostsDisabled( ) { }

###createDatabase Creates a new database - requires cluster admin privileges

createDatabase(databaseName, callback) { }

###deleteDatabase Deletes a database - requires cluster admin privileges

deleteDatabase(databaseName, callback) { }

###getDatabaseNames Returns array of database names - requires cluster admin privileges

getDatabaseNames(function(err,arrayDatabaseNames){}) { }

###getSeriesNames Returns array of series names from given database - requires database admin privileges

getSeriesNames(databaseName, function(err,arraySeriesNames){} ) { }

###createUser Creates a new database user - requires cluster admin privileges

createUser(databaseName, username, password, callback) { }

###updateUser Updates database user - requires cluster admin privileges

updateUser(databaseName, username, options, callback) { }

e.g.:
// adds database admin privilege
influxDB.updateUser('myDatabase','johndoe',{admin:true},callback);

###writePoint Writes a point to a series - requires database user privileges

var point = { attr : value, time : new Date()};
writePoint(seriesName, point, options, callback) { }

###writePoints Writes multiple point to a series - requires database user privileges

var points = [ {attr : value, time : new Date()}, {attr : value2, time : new Date()}];
writePoints(seriesName, points, options, callback) { }

###writeSeries Writes multiple point to multiple series - requires database user privileges

var points = [ {attr : value, time : new Date()}, {attr : value2, time : new Date()}];
var points2 = [ {attr : value, time : new Date()}, {attr : value2, time : new Date()}];

var series = {
    series_name_one : points,
    series_name_two : points2
};

writeSeries(series, options, callback) { }

Please note that there's a POST limit at about 2MB per request. Do not submit too many points at once.

###query Queries the database - requires database user privileges

var query = 'SELECT MEDIAN(column) FROM myseries WHERE time > now() - 24h';
query(query, callback) { }


query(query, callback) { }

###getContinuousQueries Fetches all continuous queries from a database - requires database admin privileges

getContinuousQueries( [databaseName,] callback) { }

###dropContinuousQuery Drops a continuous query from a database - requires database admin privileges

dropContinuousQuery( [databaseName,] queryID, callback) { }

###dropSeries Drops a series from a database - requires database admin privileges

query ( [databaseName ,] seriesName, callback) { }

As Jeff Atwood puts it... Read the source, Luke. If you're still stuck, read the ./examples/* files and the ./test.js file.
