I am trying to capture connection error on nodejs while using mysql or mysql2 node module. My code is
console.log("Connecting to database")
try{
var connection = mysql.createConnection({
host : process.env.DB_HOST,
user : process.env.DB_USERNAME,
password : process.env.DB_PASSWORD,
database : process.env.DB_NAME
});
connection.connect();
console.log("Connected")
}
catch(exce)
{
console.log(exce)
}
The mysql server is not running and all details are wrong here. I am expecting this code to throw a connection error but this does not happen. Instead, I am receiving the following console output.
Connecting to database
Connected
I don`t know why there is no connection error thrown by mysql module.
The following solution suggested by @Anatoly worked for me.
var mysql=require("mysql2/promise")
var connected=true
console.log("Connecting to database")
try{
var connection =await mysql.createConnection({
host : process.env.DB_HOST,
user : process.env.DB_USERNAME,
password : process.env.DB_PASSWORD,
database : process.env.DB_NAME
});
// connection.connect();
console.log("Connected")
}
catch(exce)
{
console.log(exce)
connected=false
}
