Serverless Architecture

WORK IN PROGRESS

What is included in this pattern?

We go over 2 topics in this pattern:

• Organization Strategies
• Dependency Strategies

The 01_withRequire project goes over all 3 organization strategies while defining dependencies with require

The 02_withDependencyInjection project goes over all 3 organization strategies while defining dependencies with dependency injection

Organization Strategies

There are many ways a project can be organized. In this pattern, we present 3 possible ways, starting with the simplest, and moving towards more complex. The three methods are as follows:

• Method 1: Handler
• Method 2: Handler / Helper
• Method 3: Handler / Helper / Logic

These methods are aimed to solve complexity and code size. When a service gets larger and painful to manage, moving to the next method will help manage and organize the size of your project.

Goal of Strategy

Problem:

As a project grows, code becomes hard to read, organize, understand, and maintain

Solution:

The above methods aims to solve these problems when they arise

Dependency Strategies: Require vs Dependency Injection

Rather than have all our code in 1 file, we often organize our code into different files. In order for our code to work, we need to define when fileA needs functionalty from fileB and so on. This is known as a dependency, fileA depends on fileB because it needs to use something from that file.

There are 2 general ways we can accomplish this

• Requiring Dependencies
• Injecting Dependencies
