The Phoenix Project

A deployment ready template with support for authentication, real-time chat, push notifications, files, email verification

phoe·nix

noun

(in classical mythology) A unique bird that lived for five or six centuries in the Arabian desert, after this time burning itself on a funeral pyre and rising from the ashes with renewed youth to live through another cycle.

Goal: To establish an advanced template that lays the groundwork for common mobile app API functionality such as authentication, real-time chat and push notifications.

Why Vapor?

"Server-side app development with Swift and Vapor is a unique experience. In contrast to many traditional server-side languages — for example PHP, JavaScript, Ruby — Swift is strongly- and statically-typed. This characteristic has greatly reduced the number of runtime crashes in iOS apps and your server-side apps will also enjoy this benefit.

Another potential benefit of server-side Swift is improved performance. Because Swift is a compiled language, apps written using Swift are likely to perform better than those written in an interpreted language.

Excerpt From: By Tim Condon. "Server Side Swift with Vapor."

If you are unfamiliar with Vapor 3 please first see their Getting Started Guide

Requirements

  • Swift 4.1
  • Vapor 3
  • Vapor Toolbox
  • cURL (for Push Notifications)
  • MySQL (other DBs are supported you will just have to modify the template)

Build

vapor fetch
vapor build

Run

vapor run

Environment Variables

Default environment variables can be set in Sources/App/Extensions/Environment+Extensions.swift. Note, some do not have defaults so you will need to set them in your environment or docker container.

<enviornment_property>: <default_value>
DATABASE_HOSTNAME: "127.0.0.1"
DATABASE_PORT: 3306
DATABASE_USER: "root"
DATABASE_PASSWORD: "root"
DATABASE_DB: "vapor"
SENDGRID_API_KEY:
APP_NAME: "Phoenix App"
PUBLIC_URL: "127.0.0.1:<PORT>"
PORT: 8000
X_API_KEY: "myApiKey"
NO_REPLY_EMAIL: "no-reply@phoenix.io"
MOUNT:
STORAGE_PATH: "./Storage"

Deployment

Vapor Cloud

See the Vapor Cloud Quick Start

After configuring cloud.yml

vapor cloud deploy

GCP, DigitalOcean, AWS or any other Linux Box

Deployment can be made easy with capistrano. I recommend following this great guide.

After configuring config/deploy.rb and config/deploy/production.rb

cap deploy production

	"isTyping": false
}

Send:
{
	"userId": "DI1IjCF7wI",
	"conversationId": "DIuyhSwUIf",
	"text": "Hello, World!"
}

Recieve:
{
    "text": "Hello, World!",
    "id": "HRGPSmvarY",
    "user": {
        "username": "nathantannar4@gmail.com",
        "id": "DI1IjCF7wI",

    "updatedAt": "2018-08-28T17:54:04Z",
    "createdAt": "2018-08-28T17:54:04Z"
}

When connected, the socket will accept Message and TypingStatus binary data in addition to Strings which it will convert to a Message.

Data sent to the socket will be propogated to all the other connections in the "room", this includes saved Messages and TypingStatus.

Whenever a user connects or disconnects the socket sends an updated Conversation to all connections

For other CRUD operations on Message and Conversation see InstallationController.swift
