💃 A Quick Intro to Design Patterns 🕺

Good morning, Salesforce Nerds! We all know that designing software solutions 🟰 solving problems.

We also know we’re not the first ☝️ to come across most of these problems.

In fact, from a software engineering perspective 🤓, these problems rear their ugly head regardless of what platform your dev’ing on or what the underlying business requirement is. 👺 

It’s our job as dev’s to recognize this and know when to leverage pre-packaged 📦️ solutions.

This is what we’ll start to cover in today’s article.

Agenda for today includes

• Intro to Design Patterns 🧩 

• Daily Principle

• All the Memes

What are they? 🤔 

The common definition will be something like this:

Reusable solutions to common software engineering problems found in real-world application development.

They are NOT ❌ code, but rather, really just templates for how to solve these common problems within your solution design.

We’re talking solutions for things like:

• How to create instances in your application ✍️ 

• How to relate these instances 👨‍👨‍👦‍👦 

• How to modify their behavior (even dynamically at run time!) 🤯 

It all started in ‘94 when the Gang of Four (GoF) dropped their book titled Design Patterns - Elements of Reusable Object-Oriented Software 

This really kicked off the concept of Design Patterns in the development world.

Benefits 👍️ 

This is easy 🍰🥱 

While I believe there are many benefits, I’d say the three primary ones are:

📖 Common language

Design patterns provide a standard terminology. AKA, developer jargon. This helps devs understand an implementation without having to see the code. 🔎 

🏆️ Best Practices

Design patterns follow well-understood paths. In this way, they encourage more legible, maintainable code that can be reused. 😋 

🏎️ Speed

Design patterns speed up development by providing tested & proven development paradigms. 💯 

The different types 🧩 

Where the rubber meets the road! 🛣️

The GoF listed 23 patterns and classified them into three different categories. 🗄️ 

In the coming weeks, we’ll pluck a few from each category and take a good look under the hood. 🚗 

For now, let’s get a high-level 🪂 view of these are:

🪄 Creational 

These design patterns provide a way to create objects while hiding 🥷 the creation logic.

🏗️ Structural

These design patterns concern class and object composition. 🧩 

🔃 Behavioral

These design patterns are specifically concerned with communication between objects. 📢
