Usage
Initialization [Isomorphic]
new LoggerConsole(LoggerInstance, settings)
-
LoggerInstance{Logger} - fromnew Logger() -
settings{Object} -
settings.format{Function} - This function must return String. Arguments:-
opts{Object} -
opts.userId{String} -
opts.time{Date} - Report date -
opts.level{String} - Message level, one of:ERROR,FATAL,WARN,DEBUG,INFO,TRACE,LOG,* -
opts.message{String} - Report message -
opts.data{Object} - Additional info passed as object
-
Example: [Isomorphic]
// Initialize Logger:
this.log = new Logger();
// Initialize LoggerConsole and enable with default settings:
(new LoggerConsole(log)).enable();
// Initialize LoggerConsole and enable with custom formatting:
(new LoggerConsole(log, {
format: function (opts) {
return ((Meteor.isServer) ? '[SERVER]' : "[CLIENT]") + ' [' + opts.level + '] - ' + opts.message;
}
})).enable();Activate with custom adapter settings: [Isomorphic]
this.log = new Logger();
(new LoggerConsole(log)).enable({
enable: true,
filter: ['ERROR', 'FATAL', 'WARN'], /* Filters: 'ERROR', 'FATAL', 'WARN', 'DEBUG', 'INFO', 'TRACE', '*' */
client: true, /* Output logs on both Server's and Client's console */
server: true /* Calls from Client and Server will be executed on Server */
});Log message: [Isomorphic]
this.log = new Logger();
(new LoggerConsole(log)).enable();
/*
message {String} - Any text message
data {Object} - [optional] Any additional info as object
userId {String} - [optional] Current user id
*/
log.info(message, data, userId);
log.debug(message, data, userId);
log.error(message, data, userId);
log.fatal(message, data, userId);
log.warn(message, data, userId);
log.trace(message, data, userId);
log._(message, data, userId); //--> Plain log without level
/* Use with throw */
throw log.error(message, data, usmerId);Catch-all Client's errors example: [Client]
/* Store original window.onerror */
var _WoE = window.onerror;
window.onerror = function(msg, url, line) {
log.error(msg, {file: url, onLine: line});
if (_WoE) {
_WoE.apply(this, arguments);
}
};Use multiple logger(s) with different settings: [Isomorphic]
this.log1 = new Logger();
this.log2 = new Logger();
(new LoggerConsole(log1)).enable({
filter: ['*'],
client: true,
server: true
});
(new LoggerConsole(log2)).enable({
filter: ['ERROR', 'FATAL'],
client: true,
server: true
});
