Best Practices
General Practices
Write clear, concise documentation before implementing features. Use markdown files and keep them versioned.
Commit frequently, use descriptive messages, and follow a branching strategy (e.g., GitFlow).
Maintain unit, integration, and end‑to‑end tests. Aim for at least 80% coverage.
Coding Practices
Adopt a style guide (e.g., Airbnb for JavaScript) and enforce it with linters.
Structure code into small, reusable modules. Use dependency injection where appropriate.
Profile critical paths, use lazy loading, and avoid unnecessary re‑renders.
Design Practices
Design mobile‑first, use fluid grids, and test across breakpoints.
Follow WCAG 2.1 AA. Ensure proper ARIA roles, contrast ratios, and keyboard navigation.
Maintain a component library and a design token system for colors, spacing, and typography.
Security Practices
Sanitize and validate all user inputs on both client and server sides.
Use OAuth2 or OpenID Connect. Enforce least‑privilege principles.
Run automated scans (e.g., npm audit) and keep dependencies up‑to‑date.
