nodeでmysqlを使ってInsertする方法
なんてことはありません
const connection = mysql.createConnection({
host: 'localhost',
user: 'root',
password: 'pass',
database: 'db_name'
});
connection.query(`INSERT INTO user_table (name, mail, pass) VALUES ('${user_name}', '${user_name}', '${user_name}');`, function (err, result, fields) {
if (err) throw err;
});
