log-transform

transform your logger statements

What is this?

log-transform is a simple node module that transforms found custom logger statements to something beautiful.

Getting started

npm install log-transform

Usage

Transformer takes string as a input and returns a string with the same amount of lines.

var transformer = require('log-transform')(/* options */);
transformer('this.log("hello kids");');
// 'console.log.apply(console, [\'%c\' + \'General\' + \' %c→\', \'color:#4bc800\', \'color:blue\', "hello kids"]);'

var transformer = require('log-transform')({ silent: true });
transformer('this.log("hello kids");');
// ';'

Options

all options are completely optional

• silent [default: false] when true then removes the log statements
• logFn [default: fn(className, text)] function used to replace the found log statement
• className [default: General] default value if no class name can be distinguished
• logMatcher regexp that defines how log statements should be found
• classMatcher regexp that defines how className should be found
• ignoreLinesContains list of simple strings. Lines containing these strings are ignored from processing (performance)
