Automated quality checks.
WHAT A FORMATTER DOES
Applies consistent formatting automatically.
WHAT THAT ACHIEVES
Style stops being discussed, and code review addresses substance.
WHAT TO CONFIGURE
Formatting on save and before commit.
WHAT A LINTER DOES
Flags likely errors and discouraged patterns.
WHAT TO ENABLE
Rules catching genuine errors Rules catching security problems Rules specific to your framework
WHAT NOT TO ENABLE
Rules that are matters of taste.
WHY
Warnings people ignore train them to ignore warnings.
WHAT STATIC ANALYSIS ADDS
Deeper inspection: unreachable code, possible null access, type problems, security patterns.
WHAT SECURITY SCANNING FINDS
Known vulnerable dependencies
Dangerous patterns: injection risks, weak cryptography, hard-coded secrets
WHAT TO RUN ON EVERY CHANGE
Formatting, linting, analysis, tests.
WHERE
Locally before commit, and in a pipeline.
WHY BOTH
Local checks give fast feedback; the pipeline is what enforces.
WHAT TO DO WITH EXISTING PROJECTS
Apply formatting in one separate commit, then adopt rules gradually.
