Node.js MySQL Error Handling

Question

I\'ve read several examples for using mysql in node.js and I have questions about the error handling.

Most examples do error handling like this (perhaps for brevity)

Answer 1

I guess this method is more approachable. In this case even if you fail to gain connection you throw an Internal Server Error status to client(helpful if you building a Rest Api Server) and in case there is a query error after releasing connection your sending the error. Please correct me if am wrong anywhere.

 pool.getConnection(function(err, connection){
      if(err){
        console.log(err);
        return res.status(500).json();
      };


      connection.query('SELECT * FROM TABLE', function(err,results,fields){
        connection.release();

        if(err){
          console.log(err);
          return (res.status(500).json());
        };
        res.status(201).send('OK');

      });


   });
