Overview: To enhance the developer experience for "Defi-Central," we will focus on the following areas:

• Preferred Development Environment: Setting up and configuring Visual Studio 2022 for backend development and Visual Studio Code for frontend development.
• Local Development Setup: Providing scripts and tools for easy local environment setup, including dependencies, database migrations, and local servers.
• Guidelines and Best Practices: Establishing coding standards, commit guidelines, and best practices to ensure code quality and maintainability.

Visual Studio 2022 is a powerful integrated development environment (IDE) that offers advanced features for .NET development, including support for C# .NET 8, built-in testing tools, code refactoring, debugging, and Git integration.

Steps to Set Up Visual Studio 2022:

• Install Visual Studio 2022: Download and install Visual Studio 2022 from the Visual Studio official website. Select the .NET Desktop Development and ASP.NET and Web Development workloads during installation to ensure all required components are installed.
• Clone the Backend Repository: Use Git to clone the defi-central-backend repository.

  git clone https://your-repo-url/defi-central-backend.git

• Open the Solution in Visual Studio: Open the DefiCentral.sln solution file in Visual Studio 2022.
• Install Required Extensions: Install recommended extensions for .NET development:
  • ReSharper for advanced code analysis and refactoring.
  • SonarLint for in-IDE static code analysis to detect issues early.
  • Azure DevOps extension for integrated pipeline management and work item tracking.
• Configure Debugging and Run Settings: Configure Visual Studio to use the built-in IIS Express or Kestrel web server for local debugging. Set breakpoints and run the application in Debug mode to step through code and diagnose issues.
• Use Visual Studio for Testing: Leverage Test Explorer to run and debug unit tests. Ensure code coverage by running tests and analyzing results within Visual Studio.

Visual Studio Code (VS Code) is a lightweight, cross-platform code editor ideal for frontend development with Angular. It offers a wide range of extensions, built-in Git support, and an integrated terminal.

Steps to Set Up Visual Studio Code:

• Install Visual Studio Code: Download and install Visual Studio Code from the Visual Studio Code official website.
• Clone the Frontend Repository: Use Git to clone the defi-central-frontend repository.

  git clone https://your-repo-url/defi-central-frontend.git

• Open the Project in Visual Studio Code: Open the defi-central-frontend folder in Visual Studio Code.
• Install Recommended Extensions: Install the following recommended extensions for Angular development:
  • Angular Language Service: Provides code navigation, refactoring, and auto-completion for Angular projects.
  • ESLint: Enforces consistent coding standards and identifies potential errors.
  • Debugger for Chrome: Allows debugging of Angular applications directly from VS Code.
  • Prettier: Automatically formats code according to a consistent style guide.
• Set Up Integrated Terminal: Use the integrated terminal in VS Code to run common commands, such as:

  npm install
          npm start  # Start the Angular development server
          npm test   # Run unit tests

• Use Live Server and Debugging Tools: Use the Live Server extension for real-time development and live reloading. Configure debugging settings to connect to the local Angular development server.

To streamline the local development process, provide scripts and tools that automate environment setup and common tasks, reducing the time required to get started.

Create a script (setup-backend.ps1 for Windows or setup-backend.sh for Linux/macOS) to set up the backend environment, including installing dependencies, initializing the database, and running migrations.

Sample setup-backend.ps1 Script:

# Check and install required .NET SDK
        $dotnetVersion = "8.0"
        if (!(dotnet --list-sdks | Select-String $dotnetVersion)) {
            Write-Host "Installing .NET SDK $dotnetVersion..."
            Install-Package -Name dotnet-sdk -Source chocolatey
        }

        # Restore NuGet packages
        Write-Host "Restoring NuGet packages..."
        dotnet restore

        # Apply EF Core migrations to the local database
        Write-Host "Applying EF Core migrations..."
        dotnet ef database update

        Write-Host "Backend environment setup complete!"

Create a script (setup-frontend.sh) to automate the frontend environment setup, such as installing Node.js dependencies, running tests, and starting the development server.

Sample setup-frontend.sh Script:

#!/bin/bash

        # Install Node.js dependencies
        echo "Installing Node.js dependencies..."
        npm install

        # Run initial unit tests to ensure the environment is set up correctly
        echo "Running unit tests..."
        npm test

        # Start the development server
        echo "Starting the Angular development server..."
        npm start

Provide scripts to initialize and populate the local development database with test data. Store these scripts in the scripts/ folder of the backend repository.

Sample init-db.ps1 Script:

# Initialize the SQL Server Database for Local Development

        # Connection details
        $server = "localhost"
        $database = "DefiCentralDB"
        $connectionString = "Server=$server;Database=$database;Integrated Security=True;"

        # Create the database
        Write-Host "Creating local database..."
        sqlcmd -S $server -Q "CREATE DATABASE [$database]"

        # Run EF Core migrations
        Write-Host "Applying EF Core migrations..."
        dotnet ef database update

        Write-Host "Database initialized successfully!"

To maintain code quality and consistency across the team, establish clear guidelines and best practices:

Follow consistent coding standards for C# and TypeScript:

• Use the Microsoft .NET Coding Guidelines for C#.
• Use the Angular Style Guide for TypeScript and Angular projects.
• Enforce coding standards using tools like ESLint (for TypeScript) and SonarLint (for C#) in the IDE.

Use a consistent commit message format:

• feat: A new feature
• fix: A bug fix
• docs: Documentation changes
• style: Code style changes (formatting, etc.)
• refactor: Code refactoring without changing functionality
• test: Adding or updating tests
• chore: Maintenance tasks, such as dependency updates

Example Commit Message:

feat(api): Add user authentication endpoint

        - Implement JWT-based authentication for user login
        - Add unit tests for authentication service

Set up branch policies in Azure DevOps to require pull requests for merging code into main branches. Require at least one reviewer approval for every pull request. Run automated tests and checks (SonarQube, Checkmarx) on pull request builds to ensure code quality.

Provide comprehensive README.md files in each repository to describe the project structure, setup instructions, and common tasks. Create a developer guide with onboarding steps, common workflows, and troubleshooting tips.

By setting up a well-defined development environment and guidelines:

• Boosts Developer Productivity: Ensures developers can start contributing quickly and effectively.
• Maintains Code Quality: Enforces standards and best practices across the team.
• Facilitates Collaboration: Provides a unified workflow for development, testing, and code reviews.
