const Knex = require('knex');

// createUnixSocketPool initializes a Unix socket connection pool for
// a Cloud SQL instance of Postgres.
const createUnixSocketPool = async config => {
  // Note: Saving credentials in environment variables is convenient, but not
  // secure - consider a more secure solution such as
  // Cloud Secret Manager (https://cloud.google.com/secret-manager) to help
  // keep secrets safe.
  return Knex({
    client: 'pg',
    connection: {
      user: process.env.DB_USER, // e.g. 'my-user'
      password: process.env.DB_PASS, // e.g. 'my-user-password'
      database: process.env.DB_NAME, // e.g. 'my-database'
      host: process.env.INSTANCE_UNIX_SOCKET, // e.g. '/cloudsql/project:region:instance'
    },
    // ... Specify additional properties here.
    ...config,
  });
