Juniors Best Practice
Juniors-focused best practices for React and TypeScript projects. The rules are short, practical, and organized by scope to guide consistent code reviews, refactoring, and new feature work.
When to Apply
Reference these guidelines when:
- Writing or reviewing React/TypeScript code for clarity and consistency
- Teaching junior developers or establishing baseline team conventions
- Refactoring code to align with simple, maintainable patterns
- Standardizing project-wide practices (imports, tooling, naming, commits)
Rule Categories by Priority

| 1 | Beginner Foundations | HIGH | beginner- |
| 2 | TypeScript | MEDIUM | typescript- |
| 3 | React | MEDIUM | react- |
| 4 | Styling | MEDIUM | styling- |
| 5 | Devtools | MEDIUM | devtools- |
| 6 | Assets | LOW-MEDIUM | assets- |
| 7 | Git | LOW | git- |
| 8 | REST | MEDIUM | rest- |
Quick Reference
1. Beginner Foundations (HIGH)
beginner-early-return - Prefer early returns to reduce nestingbeginner-double-negation - Avoid !isNotX patternsbeginner-unnecessary-destructuring - Keep objects intact for claritybeginner-const-vs-let - Default to constbeginner-nullish-vs-or - Use ?? for defaultsbeginner-useless-return-arrow - Remove redundant returnbeginner-uppercase-constants - Use UPPER_CASE only for stable constants
2. TypeScript (MEDIUM)
typescript-alias-naming - Use safe path alias prefixestypescript-flat-translations - Prefer flat translation keys to reduce duplication
3. React (MEDIUM)
react-string-props - Use string literals when possiblereact-children-prop - Use children for compositionreact-extends-component - Extend native element propsreact-props-typing - Keep props typing readable
4. Styling (MEDIUM)
styling-classnames-function - Use clsx for conditional classesstyling-css-states - Prefer CSS selectors for component states
5. Devtools (MEDIUM)
devtools-formatter-linter - Use formatter and linterdevtools-sorting-imports - Keep imports ordered and groupeddevtools-package-manager-lock - Use a single package manager
6. Assets (LOW-MEDIUM)
assets-svg-files - Use SVGs as components
7. Git (LOW)
git-commit-convention - Use consistent commit conventions
8. REST (MEDIUM)
rest-scalability-abstractions - Build REST layer around reusable transport abstractionsrest-naming-openapi - Keep REST naming aligned with OpenAPI contracts
