An adapter for Scrib to write logs into a log file.

npm install scrib scrib-local --save
var Scrib = require("scrib"),
    logger = new Scrib({
        "local": {
            file: "./data/log.txt",
            filter: function(message) {
                // Messages with a priority lower or equal 0 won't be logged 
                return message.priority > 0;
    }, function(e) {
        if(e) throw e;
        logger.put("Message", { 42: true }, 3, "MSG", "Logs");
        logger.put("Message2", { node: "up" }, 1, "MSG_2", "Logs");

Then your log file will look like (you can modify it using the format option):

[Thu, 01 Aug 2013 19:21:41 GMT] 3 MSG (Logs): Message {"42":true}
[Thu, 01 Aug 2013 19:21:41 GMT] 1 MSG_2 (Logs): Message2 {"node":"up"}


  • file: A path relative to your current file to the log file
  • flags = "a+": File flags to open file with
  • filter = null: A function called with every message to filter them
  • format = null: A function called with every filtered message to return a string to write to the file
