#CI/CD

A guide to integrating the Sentry SDK in production frontend applications and building a secure source maps upload pipeline for precise error debugging.

Users found the broken signup before I did after a late-night deploy. How I set up Playwright E2E tests and integrated them into CI to prevent this.

Manual builds and deploys led to shipping bugs to production. GitHub Actions automated my pipeline and eliminated human error.

Solo developers can't get code reviews? AI review tools changed that. Setting up automated code review on every PR.

Stop fearing Friday deploys. Feature Flags (or Toggles) allow you to push code to production while keeping it dormant. We explore the 4 categories of flags, how they enable Trunk-Based Development, the power of Canary Releases, and the critical importance of cleaning up stale flags to prevent technical debt.

Stop hiring 'DevOps Engineers' to fix your broken culture. DevOps is about breaking down silos between Development and Operations, not creating a new silo. We explore the 'Three Ways' of DevOps (Flow, Feedback, Learning), the importance of CI/CD, Immutable Infrastructure, and why DevSecOps is the inevitable future.

Why is it called 'Canary'? How does it differ from Rolling and Blue/Green deployments? We explore the strategy of releasing to a small subset (1%) of users first to detect issues before they impact everyone. Includes details on Metrics, Tools, and advanced strategies.

How to deploy without shutting down servers. Differences between Rolling, Canary, and Blue-Green. Deep dive into Database Rollback strategies, Online Schema Changes, AWS CodeDeploy integration, and Feature Toggles.
