Pergunta

I am using MariaDB in my node.js application. I am having the following code

         var nodeMaria = require('node-mariadb');

         var connection = nodeMaria.createConnection({
             driverType: nodeMaria.DRIVER_TYPE_HANDLER_SOCKET,
             host:'localhost',
             port:9998
         });

         connection.on('error', function(err){
             console.log(err);
             process.exit(1);
         });

         connection.on('connect', function(){
             console.log("mariadb connected");
         });

Problem

After connecting the db, It is logging "mariadb connected". After that Application is breaking without throwing any error.

Note: I had handled the error in connection connection.on('erorr',function(){});

Any help will be great.

Solução

If the application is closing, it doesn't necessarily mean that an error has occurred with connecting to MariaDB.
In fact, if there isn't anything keeping a node application explicitly open, it just closes after execution of the code.
What keeps a node application open? Event listeners. If you have an event listener listening for events, the node application doesn't close after finishing code execution. For example, if you have a http.listen command, which starts the web server and starts listening for incoming HTTP connections.
