Stop Building Things Manually
Continuous Integration and Continuous Deployment (CI/CD) means establishing an automated infrastructure that compiles, lints, formats, and tests every line of your codebase before an engineer is ever allowed to merge it into the main branch.
The Automation Ecosystem
The days of transferring a build directly from your own personal laptop to a production Unix server via FTP are long gone. The risk of the classic “it worked on my machine” problem is just too high!
Instead, we use isolated Docker containers spun up dynamically by triggers to reproduce the production environments perfectly.
Essential Automation Steps
- Linter: Does the code fit the formatting rules?
- Typechecker: Does the Typescript build without breaking any types?
- Unit Tests: Run the automated testing suite against isolated modules.
- Integration Tests: Does the entire system communicate perfectly when assembled?
- Deployment script: Auto-ship the artifact to the cloud provider!
By leaning into CI/CD, the team can focus purely on business logic rather than ops!
