That costs $15 a month, but it's cheaper than a course, it's legit, I saved me a bunch of time (I mean, people have full-time jobs managing databases) and DigitalOcean gives you referral codes that let you get credits for a certain amount of time (usually 30-60 days) and I had credit so it was free to try! If you want to give it a try sign up using my referral code and you can get $50 in credits for 30 days so it's free for you to get started.

This file serves as the primary configuration file governing your. Once you’ve identified your PostgreSQL version, your next task involves tweaking the nf file. Step 2: Modifying Connection Settings in nf. I have a decent amount of experience using MongoDB databases and have built a fairly good sized project using Prisma, which uses SQL behind the scenes but I had not ever had to actually write a SQL query and interact directly with a SQL database. ls /etc/postgresql/ This tutorial is based on PostgreSQL 15, one of the latest versions at the time of writing.

In this post, I am going to be looking at creating a managed PostgreSQL (which from now on I'm just going to call a SQL database) and connecting to it using node_postgres.
