const logger = require('@voodoo.io/fast-logger');

logger.info('My log');
logger.error('My error');
}
You can disable the logger by calling the function setCacheTTL
with a negative integer value or you can customize the TTL
of the items in the cache
const logger = require('@voodoo.io/fast-logger');
// cache is disable
logger.setCacheTTL(-1);
// buffer of 1 sec in the cache
logger.setCacheTTL(1000);
