keypunch

NodeJS Logging Module without the fancy bits.

Setup

npm install keypunch --save

const console = require('keypunch');
console.log("Hey it works!", "oh thats sick");

Log Functions

debug - Logs all function arguments & a stack trace.

log - Logs all function arguments.

info - Logs all function arguments.

warn - Logs all function arguments.

error- Logs all function arguments.

stackTrace - Logs all function arguments & a stack trace.

Log Levels

Each log function has an assigned level. When initiating your app remember to set the Keypunch log level, either with process.env.LOG_LEVEL or via JS as shown below.

const console = require('keypunch');
console.logLevel = 3;
...
console.debug("testing the request fired", req); // Won't fire a log message

Levels

debug - 1

log - 2

info - 3

warn - 4

error- 5

stackTrace - 5

Message prefixing

Message output by themselves can often require more context. Keypunch lets you add your own functions to modify the start of a log message. Here are some examples,

console.addHeaderFunction((type) => `[MyPackage (${type})] `);
console.addHeaderFunction((type) => new Date().toString());
