Usage

The options argument is always optional.

numbers is an alias for integers

sequence is an alias for sequences

var random = require("node-random");

random.integers(options, function(error, data) {
    // data is an array of numbers
});

random.sequences(options, function(error, quota) {
    // data is an array of numbers
});

random.strings(options, function(error, data) {
    // data is an array of strings
});

random.quota(options, function(error, data) {
    // data is an integer
});

random.sequences

See here for the meanings (Option names are slightly different);

• minimum - 0

• base - 10
• random - "new"

random.strings

See here for the meanings (Option names are slightly different);

• number - 1
• length - 10
• digits - true
• upper - true
• lower - true
• unique - false
• random - "new"

Examples

var random = require("node-random");

// Get 2 random numbers between 1 and 6
console.log("Rolling 2 dice");
random.numbers({
    "number": 2,
    "minimum": 1,
    "maximum": 6
}, function(error, data) {
    if (error) throw error;
    data.forEach(function(d) {
        console.log(d);
    });
});

// Get a random 3x3 grid and print the middle vertical row
random.sequences({
    "minimum": 1,
    "maximum": 9,
    "columns": 3
}, function(error, data) {
    if (error) throw error;
    console.log(data);
    console.log(data[0][1]);
    console.log(data[1][1]);
    console.log(data[2][1]);
});

// Get 20 different lowercase characters
random.strings({
    "length": 1,
    "number": 20,
    "upper": false,
    "digits": false
}, function(error, data) {
   if (error) throw error;
   console.log(data.join(" and "));
});

// Check your quota
random.quota(function(error, quota) {
    console.log("Remaining bytes: " + quota)
});
