Logger

Logger is a very simple logging library for node.js.

Installation

Install like any other NPM library:

npm install --save logger

Usage

var logger = require("logger");

Logger has 4 methods for logging:

logger.info("foo");   // yyyy/mm/dd HH:MM:SS INFO: foo
logger.notice("foo"); // yyyy/mm/dd HH:MM:SS NOTICE: foo
logger.warn("foo");   // yyyy/mm/dd HH:MM:SS WARNING: foo
logger.die("foo");    // yyyy/mm/dd HH:MM:SS ERROR: foo

After logger.die, the process will immediately exit.

If an error object is passed instead of a string, a stack trace will be printed, like this:

logger.notice(new Error("foo"));

// yyyy/mm/dd HH:MM:SS NOTICE: foo - stack trace:
// Trace: [Error: foo]
//     <stack trace>

To set a different color theme, use setTheme:

logger.setTheme({
	timestamp: "green"
})

The available properties for setTheme is:

• timestamp: timestamp, default: “blue”
• level_0: logger.info, default: “grey”
• level_1: logger.notice, default: “yellow”
• level_2: logger.warn, default: “red”
• level_3: logger.die, default: [“bold”, “red”]

The available values for themes are listed here: npmjs.com/package/colors
