How to use MySql into a lambda function in Netlify or Vercel platform
Posted on October 16, 2022
Suppose you have a MySql db and want to fetch or write to it from within a lambda function. I use Netlify function but it should be the same in other platforms.
const mysql = require('mysql2/promise')
const connOb = require('./conn')
exports.handler = async (event, context) => {
const body = JSON.parse(event.body)
const name = body.name
try{
const conn = await mysql.createConnection(connOb)
await conn.execute(`insert into mytable (name) values ('${name}')`)
}catch(e){
console.log('error on mysql')
}
return {
statusCode: 200,
body:'OK'
}
}
Don't forget to define the connection object connOb such as:
module.exports = {
host: process.env.DB_HOST,
user: process.env.DB_USER,
password: process.env.DB_PASSWORD,
database: process.env.DB_DATABASE
}
