About The Project

I have created this project to have a guide of code examples and good practices as a future reference for me and for anyone who may be interested.

I will be adding more examples that I think are interesting and that provide an extra for anyone who wants to get started in the technologies mentioned bellow.

Features

PHP8
Symfony 6
DDD guidelines
Hexagonal Architecture
SOLID
Docker
Doctrine ORM & DB migrations
Albums module with CQRS pattern (command and query bus)
Static code analysis: PHPCS, Rector, Psalm
Unit and integration tests: PHPUnit
Acceptance tests: Behat
Basic Authorization, with mandatory token to http POST endpoints
Basic JWT Authorization, with mandatory token to http PUT endpoints
NoSql: Redis examples
Frontend examples (React, Redux, Webpack, Babel, etc.): on this repo
Elastic stack (Elasticsearch, Logstash, Kibana, Filebeat)

Upcoming Features

Aggregates organization
Using native PHP amqp extension to publish events (instead of Symfony/Messenger)
RabbitMQ configuration wizard (queues and exchanges, retry, dead-letter and bindings)
Supervisor configuration wizard (file .ini per queue)

Getting Started

I will add new features and examples, this project is constantly evolving! You can see unreleased code at here

Prerequisites

docker: How to install docker? Please click here
make

Installation

Clone repo, download deps and create docker services:

git clone https://github.com/masfernandez/symfony-ddd-hexarch-cqrs.git
cd symfony-ddd-hexarch-cqrs
make composer-install
make up

Running prod env

Execute at root path:

make prod-start

Request examples

In order to create a new Album is mandatory to include a valid Token in request's Authorization header. So first, let's create a new User:

make create-demo-user
# Credentials for demo user: [email protected] 1234567890

Now, it's time to get a valid token:

curl -i -X POST 'http://api.musiclabel.127.0.0.1.nip.io/authentication' \
-H 'Content-Type: application/json' \
--data-raw '{
    "email": "[email protected]",
    "password": "1234567890"
}'

You can find the Token in response's Location header:

Server: nginx/1.19.5
Content-Type: application/json
Transfer-Encoding: chunked
Connection: keep-alive
X-Powered-By: PHP/8.0.0
Location: 4ac71eeda13c8fe7f0e4c017412bd9f2d886288cb8c88331007f2a9c7652385b
Cache-Control: no-cache, private
Date: Fri, 15 Jan 2021 11:23:45 GMT
X-Robots-Tag: noindex
Strict-Transport-Security: max-age=31536000

{}

We can publish new Albums now: (replace the value of the token here with the one you got before... obviously)

curl -i -X POST 'http://api.musiclabel.127.0.0.1.nip.io/albums' \
-H 'Authorization: Bearer 4ac71eeda13c8fe7f0e4c017412bd9f2d886288cb8c88331007f2a9c7652385b' \
-H 'Content-Type: application/json' \
--data-raw '{
    "id": "0da69030-3ed7-42b5-8aa5-25fb61dab1b2",
    "title": "Abbey Road",
    "release_date": "1969-09-26 00:00:00"  
}'

Verifying the Album created:

curl -X GET 'http://api.musiclabel.127.0.0.1.nip.io/albums?page[number]=1&page[size]=1&sort=title&fields[albums]=id,title,release_date'

We need a JWToken to make PUT operations on Albums, so let's get one:

curl -i -X POST 'http://api.musiclabel.127.0.0.1.nip.io/authentication/jwt' \
-H 'Content-Type: application/json' \
--data-raw '{
    "email": "[email protected]",
    "password": "1234567890"
}'

You can find the JWToken (header.payload.signature) in response's headers:

header+payload in Location header
signature in set-cookie header

HTTP/2 201 
server: nginx/1.19.8
content-type: application/json
location: header+payload:eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwOi8vZXhhbXBsZS5jb20iLCJhdWQiOiJodHRwOi8vZXhhbXBsZS5vcmciLCJqdGkiOiJlWFZocHBTR0JwZllTeHNZIiwiaWF0IjoxNjE3MzU1NTMyLjQyNzU3MSwibmJmIjoxNjE3MzU1NTMzLjQyNzU3MSwiZXhwIjoxNjE3MzU5MTMyLjQyNzU3MSwidWlkIjoiMGY4MzNjMjItZmVmZC00ZmFmLWE3YzItNGEwNzlhMjJjMzdjIn0

You may be asking why sending the JWToken like this... well, I'm to lazy to write hundred of words when there is a lot of information already on there. Just few tips:

Main reason is security (XSS and CSRF). This is an evolved example of the following medium article:
https://medium.com/@ryanchenkie_40935/react-authentication-how-to-store-jwt-in-a-cookie-346519310e81

Recommend read:

http://cryto.net/~joepie91/blog/2016/06/13/stop-using-jwt-for-sessions/

Don't forget the purpose of this repo: just to show some examples, crazy dev ideas and my opinionated vision on how to approach some scenarios ;)

Let's replace Album created before:

The client (React, Vue, Curl, Postman... whatever) should know how to re-construct the JWToken to make a request (remember, header + payload in Authorization header and signature in cookie)

Note: replace the values of the token here with the one you got before... obviously

curl -i -X PUT 'http://api.musiclabel.127.0.0.1.nip.io/albums/0da69030-3ed7-42b5-8aa5-25fb61dab1b2' \

--data-raw '{
    "title": "New album value here",
    "release_date": "2021-04-02 00:00:00"
}'

Docker services

Several docker services will be available and ready for use when the app starts:

RabbitMQ

http://localhost:15672
user: rabbit_user
password: rabbit_pass

Kibana

http://localhost:5601

Kibana Nginx logs configuration:

Execute below command after all ELK services are started:
```
make filebeat-dashboards
```
Go to http://localhost:5601/app/dashboards and search for "Nginx"

Kibana Symfony logs configuration:

Create an index pattern at http://localhost:5601/app/management/kibana/indexPatterns/create
- Step 1. Write "logstash*" as index pattern and press "Next" button
- Step 2. Select @timestamp for Time field and press "Create index" button
Configure logs
- Step 3. Go to http://localhost:5601/app/logs/settings and include "logs-,filebeat-,logstash*" in `Log indices´ field and confirm pressing Apply button at bottom page.

Logs can be visualized now at http://localhost:5601/app/logs/stream

Running dev env

make dev-start

Tests

make test

Docker info

There are several services in the Docker stack for this project. All services are built from official docker images except:

Nginx: Custom docker image. I will optimize some parameters soon but at this moment is just a wrapper of the official docker image. More info here
PHP-FPM: Custom docker image. It has 2 main targets, for production and development environment. Each env has some deps that you can check at here. This is also a repo I'm working on.
