loggerjs-web

Ultrafast logger for modern web | simple | lightweight | 0 dependency. Currently, built for frameworks which use process.env variable system at runtime. At present default log level is set to debug in code like:

export const CURRENT_LOG_LEVEL = process.env.CURRENT_LOG_LEVEL || LogLevel.DEBUG;

If using yarn:

yarn add loggerjs-web

• Override CURRENT_LOG_LEVEL variable in your build tool environment.

E.g. in React as:

export enum LogLevel {
  DEBUG = 'debug',
  INFO = 'info',
