Server-side Swift. The Perfect core toolset and framework for Swift Developers. (For mobile back-end development, website and API development, and more…)

Last update: Jan 6, 2023

Overview

Perfect: Server-Side Swift 简体中文

Perfect: Server-Side Swift

Perfect is a complete and powerful toolbox, framework, and application server for Linux, iOS, and macOS (OS X). It provides everything a Swift engineer needs for developing lightweight, maintainable, and scalable apps and other REST services entirely in the Swift programming language for both client-facing and server-side applications.

Perfect includes a suite of tools that will enhance your productivity as you use only one programming language to build your apps: Swift. The global development community’s most dynamic and popular server-side toolbox and framework available today, Perfect is the backbone for many live web applications and apps available on iTunes.

This guide is designed for developers at all levels of experience to get Perfect up and running quickly.

Perfect project is divided into several repositories to make it easy for you to find, download, and install the components you need:

Perfect – This repository contains the core PerfectLib and will continue to be the main landing point for the project
Perfect Docs – Contains all API reference-related material

More about Perfect

Perfect operates using either a standalone HTTP server, HTTPS server, or through FastCGI server. It provides a system for loading your Swift-based modules at startup, for interfacing those modules with its request/response objects, or to the built-in Mustache template processing system.

Perfect is built on a completely asynchronous, high-performance networking engine to provide a scalable option for internet services. It supports Secure Sockets Layer (SSL) encryption, and it features a suite of tools commonly required by internet servers such as WebSockets and iOS push notifications, but you are not limited to those options.

Feel free to use your favourite JSON or templating systems, etc.

Comments

Perfect should be more "Swifty"

We'd heard from a few people that Perfect isn't as "Swifty" as it should be. We'd love to hear what this means to you, and where you think we could improve Perfect to be more so. What is "Swifty" to you that Perfect isn't?

Is this project dead?

The last commit was 3 months ago and I haven't seen much recent activity. ~~I am unable to join the Slack channel~~. So is this project basically dead?

EDIT: I've got to join Slack now after some failed attempts (was getting HTTP 502-504)

I am looking to decide what to use for a backend and thought of server-side Swift (instead of going with some NodeJS thing) and found this but I am quite skeptical.

Swift compiler error

Hello Perfect team, I tried following the README Quick Start instructions.

After I enter the following in Terminal: git clone https://github.com/PerfectlySoft/PerfectTemplate.git cd PerfectTemplate swift build

I get: /Users/matthewtso/git/PerfectTemplate/Packages/PerfectThread-0.10.0/Sources/ThreadQueue.swift:210:97: error: cannot convert value of type 'UnsafeMutablePointer<Void>' (aka 'UnsafeMutablePointer<()>') to expected argument type 'UnsafeMutablePointer<_>'

error: exit(1): /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-build-tool -f /Users/matthewtso/git/PerfectTemplate/.build/debug.yaml

Checking my Swift version returns the following: Apple Swift version 3.0 (swiftlang-800.0.30 clang-800.0.24) Target: x86_64-apple-macosx10.9

I'm pretty new and not sure how to diagnose this, is there something I can try to fix this? Thanks!

License Rationale and Clarification

I see this great project is under the Gnu Affero License, which basically implies that any software built using this server will need to be under the same license (see https://www.gnu.org/licenses/gpl-faq.html#LinkingOverControlledInterface).

Swift.org has been released under the Apache License. Any chance this project would consider doing the same ?

Missing OpenSSL

Hello,

I built the latest version of PerfectLib with the correct Swift snapshot. However, when I import the .xcodeproj or a compiled version of the framework into Xcode whenever I try to compile my program the compiler says "Missing required module 'OpenSSL'." Also, I ran 'brew link openssl --force' to force symlink the openssl libs to /usr/local/include/openssl.

Thanks!

Deploy on AWS?

I'm assuming this can't be deployed to a real production server yet, since it can't run on linux. Is that something that is only reconcilable after Apple open sources the language?

Nevertheless, not being able to scale the servers made is definitely an issue.

Issue when launching the server on Ubuntu 15-10 : "the file / was not found"

Hello,

I have a problem when i launch the perfectserverhttp from Ubuntu 15-10.

The server launches properly, but then i can't manage to work with it. The message "The file "/" was not found" is displaying on the navigator.

Could it be because i use a virtual machine? Or did i do something wrong with the installation? I followed step by step the instructions written in the Readme files.

Thanks in advance!

Releasing version 4 of PerfectHTTP and PerfectHTTP-Server?

Hi, we recently moved from precompiled Perfect to one resolved via SPM.

We stumbled upon the crash explained in:

https://github.com/PerfectlySoft/Perfect/issues/296

only when running in Release configuration. On the very first request, app crashes in

return UnsafePointer(bytesArray).withMemoryRebound(to: Int8.self, capacity: bytesArray.count) { return String(validatingUTF8: $0) }

Now this seems to be fixed in PerfectLib from version 4.0 onwards by following commit:

https://github.com/PerfectlySoft/Perfect/commit/135fb33471f1dd316eb323f8a94d701bde2efa85#diff-69391fd63fbd9d34d8f320a64858e895ea4ab70dc9e87fafe0cfe701de2db5b0L250

The problem is that no publicly available version of HTTP and HTTP-Server depends on PerfectLib 4.0, which essentially is letting me with no access to the fix for this crash.

Long story short, is there an intent from your side to publish HTTP/HTTP-Server version 4.0 that depends on PerfectLib 4.0?

Thanks in advance. Uros

A emoji parameter bug On Linux

Platform: Linux(not happen on Mac) What happen: the server shutdown How to happen: remove permeter escapeVS, request body is '👨‍👩‍👧‍👦' Strange: set parameter escapeVS or request not contains '👨‍👩‍👧‍👦', this wouldn't happen. My question: Is the postParams wrong when the request body contains some speical emoji?

this is my request:

curl --location --request POST 'http://localhost:8181/emoji/parse?a=b' \
--header 'Content-Type: text/plain' \
--data-raw '👨‍👩‍👧‍👦'

this is my code:

func emojiParse(request: HTTPRequest, response: HTTPResponse) {
    do {
        let escapeVS = request.param(name: "escapeVS", defaultValue: "false")?.elementsEqual("true") ?? false
        if let raw = request.postBodyString {
            response.setHeader(.contentType, value: MimeType.forExtension("json"))
            let result = raw.translateUEmojiCode(escapeVS)
            try response.setBody(json: result)
        }
    } catch {
        response.status = .internalServerError
        response.setBody(string: "Error handling request: \(error)")
    }
    response.completed()
}

this is my debug on Mac:

this is the error log:

--------UPDATE----------

this request also trigger the bug.

curl --location --request POST 'localhost:8181/emoji/parse?escapeVS=false&👨‍👩‍👧‍👦=b' \
--header 'Content-Type: text/plain' \

--------UPDATE----------

Looks like a swift unicode bug on Linux?

Fatal Error When Idle "UnsafeMutablePointer.initialize overlapping range"

I've built a listener server with Perfect HTTP, listening on certain routes for Webhooks called by GitLab on certain repository actions. The project is a work in progress and primarily for my own use, though it is public on https://gitlab.com/apricum/gitlab-listener.

I'm starting the server through systemd via systemctl start and the likes. I've found it crashes after a seemingly random amount of time, sometimes a few hours, other times not even ten minutes. Reading the log with sudo journalctl -u gitlab-listener (where gitlab-listener is the name of the systemd service file), as follows:

Help

Hello everyone, I'm glad to learn how to use Perfect, but I encountered some problems. When I used Perfect Assistant to create an Empty Executable Project, I found that HTTPServer could not be dragged, and I was prompted "The Package.swift file could not be parsed", Is there a problem with my settings?
