Using HTTP

HTTP is a module as part of the Engine library containing all HTTP related APIs.

With Vapor

This package is included with Vapor by default, just add:

import HTTP

Without Vapor

To include it in your package, add the following to your Package.swift file.

// swift-tools-version:4.0
import PackageDescription

let package = Package(
    name: "Project",
    dependencies: [
        ...
        .package(url: "https://github.com/vapor/engine.git", .upToNextMajor(from: "3.0.0")),
    ],
    targets: [
      .target(name: "Project", dependencies: ["HTTP", ... ])
    ]
)

If this is your first time adding a dependency, you should read our introduction to Package.swift.

Use import HTTP to access HTTP's APIs.
