Next.js Example - Winter 2023

• Next.js
• Postgres.js

Database Setup

Copy the .env.example file to a new file called .env (ignored from Git) and fill in the necessary information.

Follow the instructions from the PostgreSQL step in UpLeveled's System Setup Instructions.

Then, connect to the built-in postgres database as administrator in order to create the database:

Windows

If it asks for a password, use postgres.

psql -U postgres

macOS

psql postgres

Linux

sudo -u postgres psql

Once you have connected, run the following to create the database:

CREATE DATABASE <database name>;
CREATE USER <user name> WITH ENCRYPTED PASSWORD '<user password>';
GRANT ALL PRIVILEGES ON DATABASE <database name> TO <user name>;
\connect <database name>;
CREATE SCHEMA <user name> AUTHORIZATION <user name>;

Quit psql using the following command:

\q

On Linux, you will also need to create a Linux system user with a name matching the user name you used in the database. It will prompt you to create a password for the user - choose the same password as for the database above.

sudo adduser <user name>

Once you're ready to use the new user, reconnect using the following command.

Windows and macOS:

psql -U <user name> <database name>

Linux:

sudo -u <user name> psql -U <user name> <database name>

API Design

• create an animal
• update an animal
• delete an animal
• get all animals but limited to x amount

/api/animals
GET => read all animals should receive a param that limit the amount of animals
POST => create a new animal
NextResponse.json({ animals: animals });

/api/animals/:id
GET => read a single animal
PUT => update a single animal
DELETE => delete a single animal
