How to hide generated javascript file in visual studio code

In this post I am going to show you a cool trick in visual studio code. Let's suppose you are writing typescript code in visual studio code and you want to hide generated javascript code.

Create .vscode folder in your folder and then create settings.json file and paste following code

{ "files.exclude": { "node_modules":true, "**/.git": true, "**/.DS_Store": true, "**/*": true, "**/*.js": {"when": "$(basename).ts"}     } }

Decorator Design Pattern

Attach additional responsibilities to an object dynamically. Decorators provide a flexible alternative to sub classing for extending functionality (also known as Wrapper)

using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; namespace DecoratorPattern { publicclass UpperStream : Stream { private Stream _stream; public UpperStream(Stream stream) { this._stream = stream; } publicoverridelong Length { get { return _stream.Length; } } publicoverrideint Read(byte[] buffer, int offset, int count) { var numberOfBytesRead = _stream.Read(buffer, offset, count); for (int i = 0; i < numberOfBytesRead; i++) { buffer[i] = (byte)char.ToUpper((char)((int)buffer[i])); } return numberOfBytesRead; } publicoverrideboo…

Strategy Design Pattern

Strategy Design Pattern
Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.

Client wants to decide at run-time what serialization it should use to serialize a type. Many different serialization algorithms are already available.
Encapsulate the different serialization algorithms using the Strategy pattern!
C# Code
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace StrategyPattern { publicinterface ISerializer { void Serialize(); } publicclass XmlSerializer : ISerializer { publicvoid Serialize() { Console.WriteLine("Xml serilizer Invoked"); } } publicclass JsonSerializer : ISerializer { publicvoid Serialize() { Console.WriteLine("Json serializer Invoked"); } }�…
