Create GitHub Actions, GitLab CI, or Jenkins pipelines with caching, matrix builds, and deployment stages in minutes.
Migrate Infrastructure
Generate Terraform variables, Kubernetes manifests, and Helm charts for consistent multi-environment deployments.
Best Practices
- Always start from a preset that matches your environment — it is faster and safer than configuring from scratch.
- Enable strict mode in TypeScript and ESLint from day one to catch bugs early in development.
- Pair ESLint with Prettier using eslint-config-prettier to avoid rule conflicts between linting and formatting.
- Keep Docker images small by using multi-stage builds and .dockerignore to exclude unnecessary files.
- Version control your config files and use shared configs in monorepos to enforce consistency across teams.
- Run validation before committing — syntax errors in config files are the most common cause of broken CI.
- Use environment variables for secrets and never hardcode API keys, passwords, or tokens in config files.
- Review generated configs before using in production — always treat generated output as a starting point.
