The light-weight and fastest node.js logging library.

---

First, you should install Prent through NPM.

npm install prent

Second, you should include Prent to your file.

var prent = require("prent");

Third, starting now, you can use Prent logging. For example:

prent.trace("Some trace message");
prent.info("2 + 2 is ", 2 + 2);

Will outputted as

[ Trace ] [ Sun, 19 Jan 2014 08:48:57 GMT ]: Some trace message [ Info ] [ Sun, 19 Jan 2014 08:48:57 GMT ]: 2 + 2 is 4

*"Trace" and "Info" are colored.

Prent can be configured through prent.init() For example, below configuration will write to console and file (logfile.txt) with frequency value 3 (write when logs >= than 3):

prent.init({
    consoleOutput: true,
    fileOutput: {
        enable: true,
        type: "File",
        path: "logfile.txt",
        frequency: 3

}});

Or, below configuration will write to console and directory with frequency value 10 (write when logs >= than 10):

prent.init({
    consoleOutput: true,
    fileOutput: {
        enable: true,
        type: "Directory",
        path: "logsdir",
        frequency: 10

}});

winston.info x 95,060 ops/sec ±0.44% (96 runs sampled)

intel.info x 58,784 ops/sec ±1.34% (96 runs sampled)

prent.info x 207,741 ops/sec ±2.98% (94 runs sampled)

Fastest is prent.info
