debug-symbols

Motivation

I built this small module because I wanted to use the popular debug module but extend it to:

• Handle different log levels out of the box
• Use colorization for different log levels (using chalk )
• Add the amazing log-symbols symbols to logs.

Usage

This module merely extends Debug's usage and leaves all else intact.

const logger = require("debug-symbols")("namespace");

// Extend logger, Internally does debug.extend()
logger.extend("extend-to");

// This runs debug() as you might expect
logger.log("Default usage");

// Adding various log levels...
logger.debug("debug");
logger.info("info");
logger.warn("warn");
logger.error("error");
logger.fatal("fatal");
logger.fail("failed");
logger.success("success");

This will log something like this:

Default Namespaces

When working with a large project, you might want to have a default main namespace.

For example.

For Example:

Assume my project is called aws-server I would want all scripts using debug-symbols to have their namespace as aws-server:script-name

The default namespace in this case is aws-server. Instead of repeating it in every script, I can set it globally using the environment variable DEBUG_NS and each module will adopt it.

In this case:

• The namespace express becomes aws-server:express.
• The namespace aws-server:admin-route remains aws-server:admin-route.

So to show my logs, all I need is add process.env.DEBUG="aws-server* and all my scripts will log as expected.
