System Design Basics: 1. K.I.S.S. (Keep It Simple Stupid) - Complexity kills - Avoid edge cases until later - Make it work, make it better later 2. Pareto principle (80/20 rule): - Identify the most important features - Solve those first - You can't solve everything at once 3. Single responsibility principle (SRP): - Classes should do one thing - Code is easier to change 4. Don't Repeat Yourself (DRY): - Avoid redundancy - Refactor code when needed 5. Separation of concerns (SoC): - Modularize code into different parts - Easier to maintain, easier to change 6. YAGNI (You Ain't Gonna Need It): - Don't over-engineer - Avoid unnecessary complexity System Design should be easy to understand, maintain and scale. Simplicity is key.

Command Design Pattern By encapsulating a request as an object, the Command Pattern is a behavioral design pattern that enables parameterizing clients with various requests, queuing requests, and recording requests. Moreover, it offers assistance with undoable operations. When you wish to separate the entity requesting it from the one sending it, this approach is really helpful. Here is a basic implementation of a Command Pattern Command ; This defines an abstract interface for executing operations. It typically has an execute() function method. Concrete Commands; These classes define the binding between an action and a Receiver object and implement the Command interface. They invoke methods on the receiver to fulfill the request. Receiver: Axis ; This is the thing that gets the job done. It is capable of carrying out the tasks that the order demands. Invoker: This is the thing that has a command and uses it to carry out the request. It is unaware of the purpose of the command.

𝐂𝐨𝐝𝐞 𝐒𝐦𝐞𝐥𝐥 𝟎𝟓 - 𝐂𝐨𝐦𝐦𝐞𝐧𝐭 𝐀𝐛𝐮𝐬𝐞𝐫𝐬 The code has lots of comments. Comments are coupled to implementation and hardly maintained. 𝐓𝐢𝐩: Leave comments just for important design decisions. Do not explain the obvious.

Don't use #designpatterns just because it sounds cool. There will be more harm than good if you don't aware of the problems you're trying to solve Here are some of the consequences - Over-engineering - Misapplication - Inflexibility - Hard-to-understand code - Adding more overhead of complexity - Performance Overhead. Make sure to only apply design patterns when you need them.

Status is something that only really matters if we are talking about Design Systems 😅 Never mind the status quo, do your DS consumers have a clear picture of component status? Is that component really available in code? Stop wasting everyone's time by making it super clear in your documentation 🤓 #DesignSystems #DesignSystemsDocumentation

12 Design Patterns You Must Know - Factory - Observer - Singleton - Builder - Adapter - Decorator - Proxy - Strategy - Command - Template - Iterator - State Which one do you use the most?

So why can't we call any solution a design pattern? There is a checklist you have to fulfill: - A pattern should have a name that describes the problem and the solution in only a couple of words. - The problem must be well stated and should also describe when it should be used. - The solution must be clearly diagramed and documented. - It should also define the trade-offs of using the solution. If your solution ticks all four of these, then congratulations, you made your own design pattern! #softwareengineering #designpatterns

If you design complex systems, you'll love sequence diagrams Complex system architectures can quickly become tangled and hard to follow. Enter sequence diagrams! They keep your design neat and easily understandable. For example, check out the diagram below. It depicts a client/server interaction, clearly differentiating between a cache hit and a cache miss. This is a prime example of how visual aids simplify complex interactions. I have two favorites for creating sequence diagrams. WebSequenceDiagrams and Mermaid. You can make sequence diagrams easily with just text.

sequence diagrams are a personal favorite and mermaid makes them easy to keep up to date and embed in markdown
