var winston = exports; | |
Expose version using | require('pkginfo')(module, 'version'); |
Include transports defined by default by winston | winston.transports = require('./winston/transports');
var common = require('./winston/common');
winston.hash = common.hash;
winston.clone = common.clone;
winston.longestElement = common.longestElement;
winston.exception = require('./winston/exception');
winston.config = require('./winston/config');
winston.addColors = winston.config.addColors;
winston.Logger = require('./winston/logger').Logger;
winston.Transport = require('./winston/transports/transport').Transport; |
We create and expose a 'defaultLogger' so that the programmer may do the following without the need to create an instance of winston.Logger directly: | var defaultLogger = new winston.Logger({
transports: [new winston.transports.Console()]
}); |
Pass through the target methods onto `winston. | var methods = [
'log',
'add',
'remove',
'profile',
'extend',
'cli',
'handleExceptions',
'unhandleExceptions'
];
common.setLevels(winston, null, defaultLogger.levels);
methods.forEach(function (method) {
winston[method] = function () {
return defaultLogger[method].apply(defaultLogger, arguments);
};
}); |
function cli ()Configures the default winston logger to have the settings for command-line interfaces: no timestamp, colors enabled, padded output, and additional levels. | winston.cli = function () {
winston.padLevels = true;
common.setLevels(winston, defaultLogger.levels, winston.config.cli.levels);
defaultLogger.setLevels(winston.config.cli.levels);
winston.config.addColors(winston.config.cli.colors);
if (defaultLogger.transports.console) {
defaultLogger.transports.console.colorize = true;
defaultLogger.transports.console.timestamp = false;
}
return winston;
}; |
function setLevels (target)@target {Object} Target levels to useSets the | winston.setLevels = function (target) {
common.setLevels(winston, defaultLogger.levels, target);
defaultLogger.setLevels(target);
}; |
Define getters / setters for appropriate properties of the default logger which need to be exposed by winston. | ['emitErrs', 'padLevels', 'levelLength'].forEach(function (prop) {
Object.defineProperty(winston, prop, {
get: function () {
return defaultLogger[prop];
},
set: function (val) {
defaultLogger[prop] = val;
}
});
}); |
@default {Object} The default transports and exceptionHandlers for the default winston logger. | Object.defineProperty(winston, 'default', {
get: function () {
return {
transports: defaultLogger.transports,
exceptionHandlers: defaultLogger.exceptionHandlers
};
}
});
