What is SonarCloud?

SonarCloud is a powerful, cloud-based service for continuous inspection of code quality and security. It supports multiple languages and provides detailed analysis on code smells, bugs, vulnerabilities, and technical debt. For teams working on ASP.NET Core and Angular applications, SonarCloud offers an invaluable tool to enforce coding standards and maintain a high level of code health.

Integrating SonarCloud with ASP.NET Core and Angular

1. Setting Up SonarCloud:

  • Create a SonarCloud Account: Start by signing up on the SonarCloud website and creating a new organization for your projects.
  • Generate Tokens: For seamless integration, generate security tokens that will be used by GitHub Actions to authenticate with SonarCloud.

2. Configuring Your Projects:

  • ASP.NET Core Configuration: Add a sonar-project.properties file at the root of your ASP.NET Core project. This file should contain necessary configurations such as project key, organization, and sources to be analyzed.
  • Angular Configuration: Similarly, for Angular, ensure that the relevant project files are included in the sonar-project.properties file.

3. GitHub Actions Setup:

  • Creating Workflow Files: In your GitHub repository, navigate to the .github/workflows directory and create a new workflow file (e.g., ci.yml). This file will define the CI/CD pipeline.
  • Adding SonarCloud Steps: Integrate SonarCloud analysis into your workflow by adding steps to install necessary tools, build the project, and run SonarCloud analysis. Here’s a sample configuration:

name: CI/CD Pipeline

on: [push]

    runs-on: ubuntu-latest

    - name: Checkout code
      uses: actions/checkout@v2

    - name: Setup .NET Core
      uses: actions/setup-dotnet@v1
        dotnet-version: 5.0

    - name: Setup Node.js
      uses: actions/setup-node@v2
        node-version: 14

    - name: Install dependencies
      run: npm install
      working-directory: ./YourAngularProject

    - name: Build Angular project
      run: npm run build
      working-directory: ./YourAngularProject

    - name: Build .NET project
      run: dotnet build
      working-directory: ./YourDotnetCoreProject

    - name: Run SonarCloud Analysis
      uses: sonarsource/sonarcloud-github-action@v1
        projectKey: 'your_project_key'
        organization: 'your_organization'
        token: ${{ secrets.SONAR_TOKEN }}


4. Running the Pipeline:

  • Push Changes: Once your workflow file is set up, push the changes to your GitHub repository. GitHub Actions will automatically trigger the pipeline.
  • Review Analysis: After the pipeline completes, you can view detailed reports on SonarCloud, highlighting any issues in your codebase.

Benefits of Using SonarCloud with GitHub Actions

- Automated Code Review: With each push, SonarCloud provides instant feedback on code quality, allowing teams to address issues early in the development cycle. - Improved Security: By identifying vulnerabilities and potential security risks, SonarCloud helps in maintaining a secure codebase. - Enhanced Collaboration: Integrating these tools promotes a culture of continuous improvement and collaboration among team members.


Integrating SonarCloud with ASP.NET Core, Angular, and GitHub Actions is a strategic move for any development team aiming to uphold high standards of code quality and security. This setup not only automates the code review process but also enhances the overall development workflow, ensuring that potential issues are caught and addressed promptly. Embrace this integration and lead your projects towards greater reliability and maintainability.
