Package Exports

iflog
iflog/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (iflog) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

iflog

A conditional console utility that only logs in development mode. It wraps all standard console methods and only outputs when process.env.NODE_ENV !== 'production'.

Installation

npm install iflog

Usage

import iflog from 'iflog';

iflog.log('This will only log in development!');
iflog.error('This error will only show in development!');
iflog.table([{ a: 1 }, { a: 2 }]);

if (iflog.isEnabled()) {
  // do something only in development
}

How it works

All methods are no-ops in production (process.env.NODE_ENV === 'production'). In development, they proxy to the corresponding console methods.
