Enhancing Code Quality through SonarQube: A Clean Coding Approach

SonarQube is an open-source platform developed by Sonar Source to perform continuous inspection of code quality for automatic reviews through static analysis of code for bugs, code smells, and security vulnerabilities. It supports various programming languages, such as Java, C#, JavaScript, TypeScript, Python, and many others.

It showcases a dashboard related to the issues found in the codebase and metrics such as code duplication, complexity, and test coverage. Such tools are also incorporated well with various build tools like Maven, Gradle, and MS Build for easy integration into the software development process.?

It helps the teams maintain the quality of code, keep to the coding standards, and identify the potential problems at an early stage in the development cycle, which finally leads to better software maintainability and reliability.?

SonarQube Impact on Project

• Early Detection of Issues: This detects issues early in the development cycle, so developers can spot them before they become a significant issue and thus avoid technical debt as well as maintaining quality in code.?

• Consistency Across Codebase: SonarQube enforces coding standards and best practices consistently across the entire codebase. All developers will have to follow the same quality guidelines, and that will lead to a more uniform and maintainable codebase.?

• Security Vulnerability Detection: It detects security vulnerabilities through security analysis rules. This scans for possible vulnerabilities in the code, so early fixes significantly reduce the chances of a security breach and enhance your application's security posture overall.?

• Maintainability Improvement: SonarQube gives you metrics and insights on the maintainability of code, including cyclomatic complexity and duplication. This allows developers to address issues that are brought up by SonarQube and generally make the codebase more readable and modifiable.?

• Improved Code Reviews: The analysis result of SonarQube provides useful feedback during code reviews. The developers can use the report of SonarQube for prioritizing code review activities and focusing on the maximum impact areas for improving the quality of code.?

• Continuous Monitoring: SonarQube enables continuous monitoring of code quality metrics over time. By tracking trends and fluctuations in these metrics, teams can identify areas of improvement and track the effectiveness of quality initiatives over time.?

• Compliance and Governance: SonarQube supports compliance with industry standards and regulations by providing built-in rulesets tailored to specific programming languages and frameworks. This helps ensure that the code meets regulatory requirements and follows industry best practices.?

• Educational Tool: SonarQube serves as an educational tool for developers by providing explanations and recommendations for detected issues. Developers can learn from these insights and improve their coding skills over time.?

• Integration Ecosystem: SonarQube integrates seamlessly with various development tools and platforms, including IDEs, CI/CD pipelines, and version control systems. This integration enables automated code analysis and ensures that code quality checks are an integral part of the development workflow.?

By leveraging these capabilities, SonarQube helps teams deliver software with higher code quality, reduced technical debt, and improved maintainability, ultimately leading to greater client satisfaction and trust in the delivered product.

Step 4:

[path ->(C:\sonarqube-9.9.1.69595\sonarqube-9.9.1.69595\elasticsearch\config\elasticsearch(yml file))] --> edit with Notepad++?

• Add line no: 22 --> #node.max_local_storage_nodes: 4

Step 5:

[path ->(C:\sonarqube-9.9.1.69595\sonarqube-9.9.1.69595\conf\sonar)] -->edit with? Notepad++?

• line no: 285 (sonar.search.port=9001) this to change = sonar.search.port=9002?

• Note: Remove # above the edited line.

Step 6:

[path ->(C:\sonarqube-9.9.1.69595\sonarqube-9.9.1.69595\bin\windows-x86-64)]??

• Open Command and run the command line StartSonar.bat?

• Successfully run sonar

Step 7:

Open the URL After configuring the local instance?

Login to https://localhost:9000.?

Using System Administrator Credentials

1. login: admin
2. password: admin --> current password: ***

Step 8:

Click the Create New Project button.?

• Create Project -> Manually?

• Give your project a Project Display name and a Project Key, and give a?Main branch name. Click the Set Up button.

Step 9:

Click locally?

• Generate a Project Token after click on continue

Step 10:

Run analysis on your Project

1. What option best describes your build?

• Choose .NET

2. Choose your build tool

• .NET core

Step 11:

Run this command line->[dotnet tool install --global dotnet-sonarscanner] in the cmd prompt.

Step 12:

project path->C:\Users\vthin\OneDrive\Documents\GitHub\api?

Execute the scanner: run the given command lines one by one.?
