Quick Setup

SonarCloud (Recommended for Open Source)

# 1. Connect repo at sonarcloud.io
# 2. Create sonar-project.properties

# sonar-project.properties
sonar.projectKey=org_project
sonar.organization=your-org
sonar.sources=src
sonar.tests=tests
sonar.javascript.lcov.reportPaths=coverage/lcov.info
sonar.coverage.exclusions=**/*.test.ts,**/*.spec.ts

SonarQube (Self-hosted)

# docker-compose.yml
services:
  sonarqube:
    image: sonarqube:lts-community
    ports:
      - "9000:9000"
    environment:
      - SONAR_JDBC_URL=jdbc:postgresql://db:5432/sonar
    volumes:
      - sonarqube_data:/opt/sonarqube/data

Quality Gates
