Hands-On Server-Side Web Development with Swift

Using the PostgreSQL database driver

Let's start by using PostgreSQL database driver:

1. Add the PostgreSQL core as a dependency in your project's SPM package manifest file:

import PackageDescriptionlet package = Package(    name: "MyJournal",    dependencies: [        ...        .package(url: "https://github.com/vapor/fluent-postgresql.git", from: "1.0.0"),    ],    targets: [        .target(name: "App", dependencies: ["FluentPostgreSQL", ...]),        .target(name: "Run", dependencies: ["App"]),        .testTarget(name: "AppTests", dependencies: ["App"]),    ])

2. After modifying Package.swift, remember to regenerate your Xcode project files to reflect the changes:

$ vapor xcode

3. Register PostgreSQLProvider in configure.swift in order for the PostgreSQL driver to work properly:

import PostgreSQL ...
