Hello I have DB that I want to connect to my Nodejs app running in the DO App Platform. I followed the concept in this post to add the env vars and CA path for allow my app to connect: https://www.digitalocean.com/community/questions/how-can-we-configure-planetscale-with-app-platform
However I think the CA path and env var may be different for Nodejs app vs Laravel like in that post. Has anyone had any luck connecting to PlanetScale DB’s via mysql2
in a Nodejs app before?
Any help is greatly appreciated 🙏

Hi there,
What I would personally do is to follow the steps from the official Planescale guide here:
https://planetscale.com/docs/tutorials/connect-nodejs-app
You can add a DATABASE_URL
environment variable with the following content:
mysql://<USERNAME>:<PLAIN_TEXT_PASSWORD>@<ACCESS_HOST_URL>/<DATABASE_NAME>?ssl={"rejectUnauthorized":true}
And then reference it in your create connection statement as follows:
require('dotenv').config();
const express = require('express')
const app = express()
const port = process.env.PORT || 3000
const mysql = require('mysql2')
const connection = mysql.createConnection(process.env.DATABASE_URL);
connection.connect()
app.get('/', (req, res) => {
connection.query('SELECT * FROM users', function (err, rows, fields) {
if (err) throw err
res.send(rows)
})
})
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`)
})
They also have an example repo here:
https://github.com/planetscale/express-example/tree/main
Let me know how it goes!
An alternative option here would be to add your database details as separate environment variables as described in the discussion that you’ve linked to and then reference the CA file as follows:
const fs = require('fs');
const mysql = require('mysql2');
const connection = mysql.createConnection({
host: process.env.DB_HOST,
user: process.env.DB_USER,
password: process.env.DB_PASSWORD,
database: process.env.DB_NAME,
port: process.env.DB_PORT,
ssl: {
ca: fs.readFileSync(process.env.MYSQL_SSL_CA)
}
});
Hope that this helps!
Best,
Bobby
