General logger utility for the browser and console.
With npm, use the familiar syntax e.g.:
npm install @reduct/logger --save
once the logger package is installed, just require it in your application file.
const logger = require('@reduct/logger');
This package also supports AMD/RequireJS. Aren't using AMD or CommonJS? Access the logger via the following global:
const logger = window.reduct.logger;
You will find a logLevels
object in the export of this package.
This object holds all valid logLevels which can be used in conjunction with the logger.setLogLevel() method.
LogLevel | Description |
---|---|
logLevels.SILENT |
No messages are logged out. |
logLevels.WARN |
Only severe messages are logged out. |
logLevels.ALL (Default) |
All messages are logged out. |
Type: Function
Argument namespace
: String
This method will return a namespaced version of the global logger instance.
Useful to diverse between logs of different modules. The returned namespaced methods are still bound to the global
logLevel, so bear in mind that if someone calls logger.setLogLevel(logLevels.SILENT);
no logs will be returned in your namespaced logger as well.
Type: Function
Argument int
: Number
This method controls the amount of logs the logger will output.
Please pass in a value of the exported logLevels
object for future compatibility.
Type: Function
Argument message
: String
Argument appendix
: *
If possible, logs out a message to the console object. Optionally you can specify a appendix which could be a reference to a HTML Element, an object or even a function.
Type: Function
Argument message
: String
Argument appendix

Basically the same as the basic log method, but tries to access the info
method of the console API.
Type: Function
Argument message
: String
Argument appendix
: *
Basically the same as the basic log method, but tries to access the warn
method of the console API.
Type: Function
Argument message
: String
Argument appendix

Will log an error to your console as well as throws an error afterwards since the Error
object cant print out
objects, functions or HTML Elements.
