After running npm install on the project, create a .env file in this directory with two entries: "PORT" and "PG_CONNECTION_STRING".
Example:
PG_CONNECTION_STRING=postgres://postgres:secretpassword@localhost:7778/nextudatabase
PORT=4000
After creating the .env, you will need to run the migrations. For doing so, run npx knex migrate:latest in your terminal
To run your project you need to run npm run dev on your terminal.
The only file that needs to be modified is user.js.
