node-pg-migrate VS PostgresApp

Why PG? For the clarity of the article to a large circle of developers, the entire explanation will be built by PostgreSQL and PG package. And in a real project, the database schema will change over time, and in order to be able to perform migrations, we will use Node PG migrate.

b) How you will manage schema migrations: every time you change tables, columns, foreign keys, every time you create or modify stored procedures, and so on, you need to do this through a migration. Here I'm at loss to recommend anything specific, but if you went with Prisma, I would read their docs and use whatever they are recommending you (if they actually recommend something). If you want something more neutral but still in the node ecosystem, node-pg-migrate might be the winner here? I'm not sure.

You’ll probably want something like this too: https://github.com/salsita/node-pg-migrate

You can use any normal DB migration tool. For k8s, I put the app's readiness probe to false, run the migrations and then toggle the probe back to true.

Here are some migration libraries:

Node - https://github.com/salsita/node-pg-migrate

A running Rails application needs a database to connect to. You may already have your database of choice installed, but if not, I recommend PostgreSQL, or Postgres for short. On a Mac, probably the easiest way to install it is with Posrgres.app. Another option, the one I prefer, is to use Homebrew. With Homebrew installed, this command will install PostgreSQL version 16 along with libpq:

I was using Postgres.app, but of course, you can download it in any way as long as it works.

There are two ways to connect with the Postgres database which can be in the terminal or using a Postgres GUI client app like DBeaver. But first, download the PostgreSQL installer for macOS or Windows, depending on your OS. The setup and installation come with the psql command, a tool shipped with Postgres that allows you to communicate with Postgres through the command line.

6a. Even stricter option is an "append-only" aka "timeseries" schema, which I highly recommend. Can't remember the last time I didn't use one.

7. If you happen to be testing on a Mac, https://postgresapp.com/ is easier than the MacPorts or Homebrew packages.

And if you're on a Mac, Postgres.app makes it even easier: https://postgresapp.com/

A great app for managing PostgreSQL databases is Postgres.app.
