SyntaxError: Unexpected token ':' in typescript but working in run dev

Recently, i'm trying to learning about typescript. I have a proble in this part

const connection = mysql.createConnection(config);
//CONNECT TO MYSQL
connection.connect((err: any) => {
    if (err) throw err;
        console.log("Connected!");
    }
);

When i run it with nodemon ./src/index.ts , it is working fine. There is no error, but when i run it with npm run postinstall, i get this error

connection.connect((err: any) => {
                       ^

SyntaxError: Unexpected token ':'
