Real World - Conduit 🌏
"The mother of all demo apps." 🔥While most "todo" demos provide an excellent cursory glance at a framework's capabilities, they typically don't convey the knowledge & perspective required to actually build real applications with it. ✅ Real World solves this by allowing you to choose any front-end like 🌈 : • React / Redux / Mobx • Angular • Vue • Elm • Aurelia • Clojure And any back-end like 🌀 : • ASP.NET Core • Node / Express • F# • Laravel • Django • Rails • Go + Gin • Rust • Scala & Play Framework • Hapi.js And see how they power a real world, beautifully designed fullstack app called "Conduit". ✨ https://t.me/pgimg/128 [ Projects ] : bit.do/reworld 〰〰〰〰〰〰 #Template #RealWorld @ProgrammingTip

Favor Privileges over Role Checks ⛔️
A very common practice in web applications, especially those written using the ASP.NET built-in Role provider, is to perform role checks throughout the code to determine whether a user should have access to a particular page or control or command. 🔍
For instance, you might see something like this ♻️ :
if (User.IsInRole(Roles.Administrators))
{
SomeSpecialControl.Visible = true;
}
The problems with the maintainability of this approach become apparent after a short while.❗️
For one, any buttons or other controls on the SomeSpecialControl above that post back to the page should also do a role check to ensure the user submitting the postback is in an acceptable role, otherwise a security hole may be present and users outside of these roles may be able to perform privileged actions. ☠️
🔸🔹🔸🔹
Introducing Privileges ✅
Wouldn't it be better to act like this❓
EditorPanel.Visibility = CurrentUser.CanEdit(CurrentArticle);This is very clear and is at the appropriate level of abstraction. 💎 CanEdit isn’t itself a privilege; we can look at it as a sort of helper method in this case that lets us write clear and concise code. ✨ https://t.me/pgimg/127 [ Full Article ] : bit.do/prauth 〰〰〰〰〰〰 #AspMvc #Authorization @ProgrammingTip

InversifyJS ⚡️
A powerful and lightweight inversion of control container for JavaScript & Node.js apps powered by TypeScript. 💎
About 👤
InversifyJS is a lightweight (4KB) inversion of control (IoC) container for TypeScript and JavaScript apps. 💉
An IoC container uses a class constructor to identify and inject its dependencies. 🗂
InversifyJS has a friendly API and encourages the usage of the best OOP and IoC practices. ✅
Motivation 💜
JavaScript now supports object oriented (OO) programming with class based inheritance. These features are great but the truth is that they are also dangerous. ☠️
We need a good OO design (SOLID, Composite Reuse, etc.) to protect ourselves from these threats. The problem is that OO design is difficult and that is exactly why we created InversifyJS. ✨
InversifyJS is a tool that helps JavaScript developers write code with good OO design. 💯
Philosophy 🌀
InversifyJS has been developed with 4 main goals 🔝 :
• Allow JavaScript developers to write code that adheres to the SOLID principles. ☝🏻
• Facilitate and encourage the adherence to the best OOP and IoC practices. 🔥
• Add as little runtime overhead as possible. ⏰
• Provide a state of the art development experience. 🌈

A Mini-Course on React Native Flexbox ✨
Flexbox solves design issues that are particularly challenging on mobile, and it does so strikingly well — without requiring hacky CSS or Javascript tricks. 🗂
But there’s a learning curve.
The property names all sound incredibly similar and do nothing to indicate what sets them apart. ↔️
On top of that, each property has a set of values that are mostly similar, yet slightly different, from each other. And to compound the confusion, not all properties of the Flexbox standard are included in React Native. 🌀
This can cause surprises when you try to follow regular CSS documentation, only to discover that React Native doesn’t implement a particular feature, such as reverse flex❗️
To help make it easier to internalize the rules of Flexbox, I’ve decided to write the guide that I would have liked to read — with the underlying concepts explained and simple examples along the way. 👾
Doodle along with me and get comfortable solving design scenarios with Flexbox. 💎

API Feature Folders ⚡️
In ASP.NET Core (and unlike ASP.NET 5 / Web API 2), Web API controllers are just controllers. 🗂
You don’t need to inherit from a different base type or anything like that. ❌
What’s more, your API controllers should be returning DTOs that are separate from your underlying domain or data model. ↔️
What I’ve found to be a better organization is to do away with the Controllers folder (or keep it around if you’re using view-based controllers) and instead use feature folders for your APIs. 💎
I’m partial to having a root level API folder but if you’d prefer to put your features in the root of the project that would work, too. 👍🏻
Within each feature folder, you include the controller along with any model types it needs to work with, like this 👾 :
https://t.me/pgimg/124
Obviously one benefit of this approach is that it’s more cohesive. ✅
Things that change together are located physically next to one another, and the friction involved in moving between different folders with too many files in them is greatly reduced. ✂️
Another nice thing about this approach is that it just works. Unlike view-based controllers, you don’t need to change anything about how ASP.NET Core is configured to have this organization structure work for you. ✨

A shorter and URL friendly GUID ✨
This a small helper class in C#. 👾
The class encodes a GUID into a 22 character long string and decodes the string back to the original GUID again. ✅
It takes a standard GUID like this 🔬 :
c9a646d3-9c61-4cb7-bfcd-ee2522c8f633And converts it into this smaller string 💎 :
00amyWGct0y_ze4lIsj2MwIt basically just converts a GUID into a base64 string and shortens it a bit. ⚡️ https://t.me/pgimg/123 [ Article ] : bit.do/guids 〰〰〰〰〰〰 #CSharp #GUID @ProgrammingTip

Avoid Lazy Loading Entities in ASP.NET Applications 🙅🏻♂️
Lazy Loading is an Entity Framework feature that lets you worry less about the specific amount of data you need to fetch with a given query. 😌
Instead, you write simple queries, and Entity Framework will load the minimal amount of data (which is a good thing), and then will only fetch additional data on an as-needed basis. ✅
That is, rather than eager loading all of the related data a given entity might have, lazy loading is a technique that has EF perform the minimal amount of work needed up front, and then only performs additional work if it turns out to be necessary. ⚠️
This sounds like a great feature, but you should turn it off in your ASP.NET web apps. 🚫
This article explains why you should do this. 🧐

Blazor will have all the features of a modern web framework, including ✨ :
• Components
• Routing
• Layouts
• Forms and validation
• Dependency injection
• JavaScript interop

Using MariaDB with ASP.NET Core 2.0 🌊
What is MariaDB❓
MariaDB is a community-developed fork of the MySQL relational database management system intended to remain free under the GNU GPL. 🐧
Development is led by some of the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle Corporation. 💎
Basically it is a fork of MySQL which is guaranteed to stay open source, and as noted it is supposed to be a drop-in replacement for MySQL. ✨
So let’s put this to the test with a simple ASP.NET Core application. 🔥

Use DbContextPooling to Improve the Performance : .NET Core 2.1 Feature 💎
If you are familiar with .NET Core, then you might be knowing AddDbContext method. 🧐
This method is used to inject dependency of DbContext into your controller and it should be written in the Startup.cs class. 💉
So in case of AddDbContext, a new instance will be created for each request and would get disposed once the work is done. ♻️
New contexts are getting created for each request. ⏳
That is still fine but if there are more than 1k requests – 1k times object will be created and disposed, unless you have made it a Singleton. ☝🏻
Creating and disposing of so many objects may impact the performance. ❌
How DbContextPooling can help❓

Principle of Least Surprise 😳
Principle Statement :
In interface design, always do the least surprising thing. 😨
Description :
Never surprise the user. ❌
An interface should behave exactly as the user thinks it behaves. ✅
What surprises the user depends on the kind of interface and the type of user. 🖥
The central idea of PLS is to think about how the user would want to use the interface. 🤳🏻
Principle of least astonishment is when you, as an API designer, prevent your users from saying WAT. 😱
🔸🔹🔸🔹
Examples :
1️⃣ Consider an elevator with a button next to it that says "call". ☎️
When you press the button, the payphone phone rings (rather than calling the elevator to that floor). ❌
The correct design would be to put the call button next to the phone rather than the elevator. ⛓
2️⃣ Think of a web page that has popup window that shows a windows style error with an 'ok' button on it. 🆗
People click the 'ok' button thinking it is for the operating system and instead go to another web page. 🌐
This astonishes the user. 😦
3️⃣ The name of a function should reflect what it does. Otherwise, a user of the function will be unpleasantly surprised❗️
Bad :
int multiply(int a, int b)
{
return a + b;
}
Better :
int multiply(int a, int b)
{
return a * b;
}
🔹🔸🔹🔸
When it comes to an API ... 👾
• Think about a toString() method that instead of printing out the fields returns back "to be implemented". 🤥
• An equals() method that works on hidden information. 👁
• Sometimes people try to implement a sorted list class by changing the add method to call sort() on the array afterwards. 🗂
This astonishing because the add method is supposed to append to the list. 🗳
This is especially astonishing when one gets back a List object with no knowledge that somewhere deep inside, someone violated the interface contract. 🤔
Having a method that does one distinct thing contributes to reduction of astonishment. ✅
