    How to Do Code Review

    Code reviews are essential for maintaining code quality as teams grow, but they can create bottlenecks and conflicts without proper guidelines. Effective code reviews require both authors and reviewers to follow best practices: authors should keep changes small, self-review first, and provide clear descriptions, while reviewers should respond within 24 hours, focus on constructive feedback, and approve when code is good enough rather than perfect. The typical workflow involves creating pull requests, running automated checks through CI, conducting human reviews, making updates based on feedback, and deploying approved changes. AI tools like CodeRabbit can complement human reviewers by handling routine checks and providing consistent feedback, ultimately improving developer velocity while maintaining code quality.

    Modern deployment the right way

    Manual infrastructure setup doesn't scale for modern web applications. Docker solves this by containerizing applications into portable, versioned units that run consistently across environments. For complex multi-service applications, orchestration tools like Kubernetes manage containers automatically, handling scaling, restarts, and traffic routing through a declarative infrastructure-as-code approach.

    Stop Deploying Just To Test!

    Traditional staging environments create bottlenecks when developers deploy every small change for testing. Remocal testing (remote + local) offers an alternative by connecting local applications directly to staging environments without deployment. Tools like mirrord enable this by intercepting network traffic, mirroring environment variables, and proxying requests between local processes and Kubernetes clusters. This approach maintains production-like testing conditions while eliminating build-deploy cycles, reducing feedback loops from hours to minutes, and keeping developers focused on code rather than pipeline management.

    Introducing Branching 2.0

    Supabase introduces Branching 2.0, removing the Git requirement for creating database branches. Users can now create isolated copies of their production environment directly through the dashboard, CLI, or API without needing GitHub integration. The new system supports both Git-based and Gitless workflows, allowing developers to experiment with schema changes, functions, and configurations safely before merging to production. While the feature offers easier access for no-code users, it has current limitations including support only for public schema changes and manual conflict resolution.

    GitHub Actions Workflows: How to Create and Manage

    GitHub Actions workflows are YAML-based CI/CD pipelines that automate software building, testing, and deployment processes. Workflows consist of jobs that run in parallel by default, with each job containing sequential steps. They're triggered by repository events like pushes, pull requests, or schedules. Key features include matrix builds for testing across multiple environments, job dependencies using the 'needs' keyword, environment variables, and concurrency controls. The platform supports reusable actions from the GitHub Marketplace and allows integration with external tools through custom actions.

    Using ApplicationSet to deploy to multiple clusters

    ApplicationSets in ArgoCD enable automated deployment across multiple Kubernetes clusters using generators. The article demonstrates two approaches: list generators with hardcoded cluster configurations for specific environments (test/prod), and cluster generators that dynamically discover clusters using label selectors. Both methods allow templating of ArgoCD applications to deploy the same application across different environments while maintaining cluster-specific configurations.

    You should delete tests

    Challenges the common belief that tests should never be deleted, arguing that tests exist primarily to build confidence in code changes. When tests become flaky, overly brittle, too slow to run regularly, or test outdated requirements, they actually decrease confidence and should be removed. The key principle is that any test that harms rather than helps developer confidence in their changes should be deleted rather than maintained.
