create a config file in your home directory ~/.gatorconfig.json with this content:

{
  "db_url": "postgres://example"
}

install go

on Linux (debian/ubuntu):

sudo apt install go

on macOS with brew:

´´´ brew install go ´´´

postgres install (you need at least version 15):

Linux:

install it with your paket manager:

sudo apt update
sudo apt install postgresql postgresql-contrib

make sure its installt and has the right version:

psql --version

set a password:

sudo passwd postgres

start the server:

sudo service postgresql start

or

sudo systemctl start postgresql

macOS with brew:

install:

brew install postgresql@15

make sure the installed version is at least 15:

psql --version

start the server: on Linux:

sudo service postgresql start

on macOS:

brew services start postgresql@15

postgres setup

enter the psql shell: macOS: psql postgres Linux: sudo -u postgres psql

your command prompt should look like this:

postgres=#

create a new database:

CREATE DATABASE gator;

connect to the new database:

\c gator

your command prompt should look like this:

gator=#

if your on Linux set the user password (not on macOS):

ALTER USER postgres PASSWORD 'postgres';

to exit use

exit

now you need to create the ~/.gatorconfig.json in your home dircetory (you can just use nano or vim and then copy one of the following configurations in) config file this file determines the database you will query against and your user:

{
  "db_url": "protocol://username:password@host:port/database?sslmode=disable",
  "current_user_name": "username_goes_here"
}

if you just followed the steps above, and you're on Linux this should work for you:

{
  "db_url": "postgres://postgres:postgres@localhost:5432/gator?sslmode=disable",
  "current_user_name": "username_goes_here"
}

if you are on macOS this should work for you:

{
  "db_url": "postgres://postgres:@localhost:5432/gator?sslmode=disable",
  "current_user_name": "username_goes_here"
}

if you want to remove the postgres service (if you do this you cant use the programm anymore):

sudo systemctl disable postgresql

install the program

go install github.com/OhRelaxo/Blog-Aggregator
