When you create your Sequelize object  pass false to the logging parameter  var sequelize   new Sequelize  database    username    password             disable logging  default  console log   logging  false       For more options  check the docs

If  config config json  file is used  then add  logging   false to the config json in this case under development configuration section        file config config json                    development              username    username            password    password            database    db name            host    127 0 0 1            dialect    mysql            logging   false                 test

Here is my answer   Brief  I was using typeorm as a ORM library  So  to set the query logging level I have used the following option instead of directly setting the logging option as false   Solution  File name - ormconfig ts         type   process env DB DRIVER       host   process env DB HOST       port   process env DB PORT       username   process env DB USER       password   process env DB PASS       database   process env DB NAME       migrations    process env MIGRATIONS ENTITIES        synchronize   false       logging   process env DB QUERY LEVEL       entities             process env ORM ENTITIES             cli              migrationsDir    migrations             And  in the envrionment variable set the DB QUERY LEVEL as   query    error     Result  As a result it will log only when the query has error else it won t   Ref link  typeorm db query logging doc  Hope this helps  Thanks

As in other answers  you can just set logging false  but I think better than completely disabling logging  you can just embrace log levels in your app  Sometimes you may want to take a look at the executed queries so it may be better to configure Sequelize to log at level verbose or debug  for example  I m using winston here as a logging framework but you can use any other framework     var sequelize   new Sequelize  database    username    password       logging  winston debug       This will output SQL statements only if winston log level is set to debug or lower debugging levels  If log level is warn or info for example SQL will not be logged

All of these answers are turned off the logging at creation time   But what if we need to turn off the logging on runtime    By runtime i mean after initializing the sequelize object using new Sequelize    function   I peeked into the github source  found a way to turn off logging in runtime      Somewhere your code  turn off the logging sequelize options logging   false     Somewhere your code  turn on the logging sequelize options logging   true
