• BuildError Handler for build errors

• Start new PGX trx from controllers only

• /api/v1 is the base path for all routes except / for health check

• /models can live as a separate repo and can be imported as a git submodule

• To run the sample product API implementation, create a table called products using the following query:

CREATE TABLE IF NOT EXISTS products (
  id SERIAL PRIMARY KEY,
  name varchar(255) NOT NULL,
  description text NOT NULL,
  price int NOT NULL,
  created timestamp NOT NULL,
  modified timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
);
