Technical details of this example

Setting up the database

You have to create the database manually using this command after connecting to the default database:

CREATE DATABASE northwind;

Setting up the connection

You may customize the db connection options by editing connect.ts. By default, these are the options:

const pool = new pg.Pool({
  user: 'postgres',
  password: 'postgres',
  database: 'northwind'
});

By default, the database will listen on port 5432 therefore it is not set above.

Building the application

npm run build

Testing the application

npm test

Starting the application

npm start

Creating sample data

After starting the application (it will listen on localhost:3000 by default) you can generate / recreate the sample dataset by submitting localhost:3000/initDb. Alternatively if you start unit tests (npm test) then the database will be initialized automatically.
