log5 - Simple logging utility.
Provides a 5-level logging facility with timestamps.
The levels are: 1 = ERRORS, 2 = WARNINGS, 3 = INFO, 4 = VERBOSE, and 5 = DEBUG
npm install log5
// call by level type initial (E, W, I, V, D) log = require("log5"); // log is a default logger function set to level 3 log.E("Error"); // writes "Error" to console log.I("Info"); // writes "Info" to console log.V("Verbose"); // doesn't write anything. log(4); // change log level to 4 log.V("Verbose"); // writes "Verbose" to console // Usage by number log(2, "Warn"); // writes "Warn" to console log(4, "Verbose"); // writes "Verbose" to console log(5, "Debug"); // doesn't write anything.
Loggers with prefix
log_foo = require("log5")("Foo: "); log_foo.I("Info"); // writes "Foo: Info" to console
Use with "g"
If you combine the "log5" module with the "g" module, you can do this, to globalize the log5 functions and set a log level of 1
require("g")("log5")(1); E("this prints"); W("this doesn't");
