Tiny-node-logger NPM

Features

100% test coverage
Zero dependencies 👌
Colored log levels for ⚪ TRACE, 🔵 DEBUG, ⚫ INFO, 🟡 WARN and 🔴 ERROR
Timestamps and flags to easily spot warnings (!) and errors (X)
Right aligned filename & line numbers just like in devtools
Handles nicely the logging of objects using util inspect
Daily inspiring quotes 🤦‍♂️

Install

npm install tiny-node-logger

Usage

Simple

const { log } = require("tiny-node-logger");

// You can either use the logger as a function...

log("Hello world");

// ...or as a tagged template

log`Hello world`;

Using import (ES6 / Typescript)

import logger, {debug} from "tiny-node-logger";

logger.level = "debug";

debug("Hello modules");

Levels

const logger = require("tiny-node-logger")

const {
    trace, debug, info, warn, error
} = logger;

logger.level = "trace";

trace`this is a trace message`;
debug`this is a debug message`;
info`this is an info message`;
warn`this is a warn message`;
error`this is an error message`;

To just use log(...) is similar to use log.info(...) but it ignores any threshold set by log.level.

For more examples please look in the fixture folder

Benchmark

console.log x 1,655 ops/sec ±4.35% (77 runs sampled)
simple x 1,596 ops/sec ±3.63% (85 runs sampled)
tagged templates ... x 1,465 ops/sec ±4.88% (75 runs sampled)

Fastest is console.log ...BUT NOT BY MUCH!!!
