Hi, you need to bind (from FAQ - What happened to replaceConsole - it doesn’t work any more?):

console.trace = logger.trace.bind(logger);
console.debug = logger.debug.bind(logger);
console.log   = logger.log.bind(logger);
console.info  = logger.info.bind(logger);
console.warn  = logger.warn.bind(logger);
console.error = logger.error.bind(logger);
