Modelling business requirements with Eloquent.

The Ugly

• creates model in controller - move to command bus

Case Study

• Use the business terminology. ** Leaky Abstractions ** - save method inside of model

** Domain-Driven Eloquent

Level up with a Microservices architecture

Why?

• growth

Design MA -> Deploy as a Monolith

How?

• Domain driven design - language ubiquitous in a domain.
• CQRS - Command and Query Request Segregation - write model and read model
• Request Journey

• Package Exploration

• Packages can mimic the language of the business.

Patterns that pay off

Matt Stauffer https://www.youtube.com/watch?v=FNyUX2jVMeE&list=PLEkJYA4gJb7_FKspNTgrve7FUb3A1dT3y&index=12

Preventative Patterns

Do this on every app no matter what.

Reactive Patterns

Feel/see the pain, then choose the fix There is a need.

**Problem: we just use patterns without first identifying a need ** We just want to use the favourite tool.

** Don’t do stuff you don’t need **

** Cost of change ** Well written code minimises the cost of change.

Write code that is easy to delete.

Matt’s Patterns

Process

Architecture

(Re)factoring

No precogs

• You think you can predict the future
• You can’t
• Do the best work with the requirements which you have

Codebase Consistency

Everyone writes code the same way

Four Eyes

• Code always have two sets of eyes on it.

Architecture Patterns

Monolith First

Seeds not dumps

Test to save your job

• what is most likely to break
• what would be the biggest nightmare
• what needs to work

(Re)factoring patterns 26:37

• Seed each test - setup data in each test, don’t do this up front.

  Custom Requests - for preparing data

• most controllers 1, get data, 2 process, 3 get data out

• not form requests.
• eg SignUpRequest - extending Illuminate Request class

View Data Composition

Presenter - layer on top of model (like decorator for views) 36 mins in

View Model - takes data in and exports the way you want

Responsible - interface for an object which can be converted into a response

View components -

Front End Filters

Filtering in controllers

Pipeline

Feature tests powered by seeders

Arrange -> Act -> Assert Don’t keep with the other seeders.

• should rebase not amend

git log --graph -- oneline --all

git reflog

Try rebasing: git rebase master

• annotations
• multi-tenancy 09:01
• domain specific classes
• slim controllers
• use Facades (not their own) -> contracts and dependency injection
• monolith and packases
• interfaces good for learning code
• clearly defined APIs
• passing Eloquent models around take care with packages
• Homestead -> Docker + Kubernetes
• Tech debt weeks - 1 week a month - > customer value - just improving what you have got
• remote first
• document decisions
• write things down!
• markdown files in the code
