• Use nvm to switch to the project's Node.js version:

nvm use

• Install project dependencies:

npm install

• Change to the directory containing your database scripts:

cd db

• Run the following command to create the database and user:

psql -U postgres -f create_user_and_db.sql

*** Note: If you are using a different user than the default, replace postgres with your username. You will be prompted to enter your password. Enter the password you created during the installation process. Sudo might be required to run this command.

Homebrew usually configures PostgreSQL to use the active OS user as the default database user.

To confirm the superuser name - enter PostgreSQL with psql postgres then type \du; to list the users. Exit postgres with \q

• Run the following command to create the database and user:

psql -U <super_user_name> -d postgres -f create_user_and_db.sql

• Run the second script to create the necessary tables in the new database:

psql -U test_user -d test_db -f create_tables.sql

• Log in to the database to verify the tables:

psql -U test_user -d test_db

• List the tables:

\dt

• You should see the following tables:

              List of relations
 Schema |       Name        | Type  |  Owner
--------+-------------------+-------+----------
    public | paintings | table | test_user
    (1 rows)

• Exit the database:

\q

• In the db folder run the following command to convert the CSV data to JSON:

node convert-csv-to-json.js

• You should see the following output:

JSON file created

You can view the JSON file in the data directory. File name: data.json.

• Create a .env file in the root directory of the project.
• Add the following environment variables to the .env file:

DB_HOST=localhost
DB_DATABASE=test_db
DB_USER=test_user
DB_PASS=test1234
DB_PORT=5432
DB_URL="postgresql://$DB_USER:$DB_PASS@$DB_HOST:$DB_PORT/$DB_DATABASE"

• Replace localhost with the hostname of your database server.
• PORT 5432 is the default port for PostgreSQL. If you are using a different port, replace 5432 with your port number.
• Save the file.

• Run the following command to load the JSON data into the database:

node load-data.js

• You should see the following output:

All paintings have been inserted

• You can also view the data in the database using the psql command:

psql -U test_user -d test_db

• Verify that the data has been loaded into the database:

SELECT * FROM paintings;

• To exit the database, run the following command:

\q

• If you encounter issues during installation or setup, consult the PostgreSQL documentation or relevant community forums for assistance.
