logless

About

Logless is a lightweight logging library specially crafted for serverless apps.

Install

npm install --save @thetimes/logless

Usage

const loggerFactory = require("@thetimes/logless");

const config = { logLevel: "debug" };

const log = loggerFactory(config, requestID);

log("something's up!");

Using a custom log function

By default logless uses console.log as a log function. But you can define your own by passing it as a config parameter:

const loggerFactory = require("@thetimes/logless");

const myCustomLogFunction = msg => process.stdout.write(msg);

const config = {
  logLevel: "warn",
  logFn: myCustomLogFunction
};

const log = loggerFactory(config, requestID);

log("something's up!");
