pgpass

Install

npm install pgpass

Usage

var pgPass = require('pgpass');

var connInfo = {
  'host' : 'pgserver' ,
  'user' : 'the_user_name' ,
};

pgPass(connInfo, function(pass){
  conn_info.password = pass;
  // connect to postgresql server
});

Description

This module tries to read the ~/.pgpass file (or the equivalent for windows systems). If the environment variable PGPASSFILE is set, this file is used instead. If everything goes right, the password from said file is passed to the callback; if the password cannot be read undefined is passed to the callback.

Cases where undefined is returned:

• the environment variable PGPASSWORD is set
• the file cannot be read (wrong permissions, no such file, ...)
• for non windows systems: the file is write-/readable by the group or by other users
• there is no matching line for the given connection info

There should be no need to use this module directly; it is already included in node-postgres.

Configuration

The module reads the environment variable PGPASS_NO_DEESCAPE to decide if the the read tokens from the password file should be de-escaped or not. Default is to do de-escaping. For further information on this see this commit.

Tests
