    appenders: {
        hangoutAlert: {
            type: '@kevit/log4js-hangout',
            space: '****',
            key:'****',
            token:'****'
        }
    },
    categories: {default: {appenders: ['hangoutAlert'], level: 'warn'}}
});

Without webhookUrl

####With webhook url

log4js.configure({
    appenders: {
        hangoutAlert: {
            type: '@kevit/log4js-hangout',
            webhookUrl: 'https://chat.googleapis.com/v1/spaces/*****/messages?key=*****&token=***'
        }
    },
    categories: {default: {appenders: ['hangoutAlert'], level: 'warn'}}
});

This configuration will send all warn (and above) messages to the respective hangout room.

####With multiple appenders

log4js.configure({
	appenders: {
		out: {type: 'stdout'},
		allLogs: {type: 'file', filename: 'all.log', maxLogSize: 10485760, backups: 10, compress: true},
		outFilter: {
			type: 'logLevelFilter', appender: 'out', level: process.env.LOG_LEVEL || 'all'
		},
		hangout: {
		    type: '@kevit/log4js-hangout',
		    webhookUrl: 'https://chat.googleapis.com/v1/spaces/*****/messages?key=*****&token=***'
		    },
		hangoutFilter: {
			type: 'logLevelFilter', appender: 'hangout', level: process.env.ALERT_LOG_LEVEL || 'warn'
		}
	},
	categories: {
		default: {appenders: ['allLogs','outFilter', 'hangoutFilter']}
	}
});

This configuration displays use of multiple appenders.

• outFilter: Push log in stdout with filter LOG_LEVEL set in environment, if not set then all levels
• hangoutFilter: Push log in hangout-webhook with filter ALERT_LOG_LEVEL set in environment, if not set then warn levels
