Sequelize Create Database

Question

Is there a way to have sequelize create the database I\'m trying to connect to if it doesn\'t exist?

I have a raw MySQL instance and I get this error back:

Answer 1

I didn't have this problem with Postgresql but I did have with mysql. Solution was creating a pre-migrate script and trigger it before the sequelize migration, here's part of my package.json :

"db:pre-migrate": "node scripts/createDB.js",
"db:migrate": "npm run db:pre-migrate && node_modules/.bin/sequelize db:migrate",

and similarly to what was proposed in some answer here, you could create this createDB.js using modules like node-postgres or mysql(or any other that connects to mysql with raw queries):

const mysql = require('mysql2/promise');

const dbName = process.env.DB_SCHEMAS || "YOUR_DB";

mysql.createConnection({
    host: process.env.DB_HOST || "127.0.0.1",
    port: process.env.DB_PORT || "3306",
    user     : process.env.DB_USER || "root",
    password : process.env.DB_PASSWORD || "root",
}).then( connection => {
    connection.query(`CREATE DATABASE IF NOT EXISTS ${dbName};`).then((res) => {
        console.info("Database create or successfully checked");
        process.exit(0);
    })
})
