📚 Learning Notes: Input Sanitization with Express Validator & TDD While learning backend validation, I came across an important distinction: ✅ Validation checks if data is correct. ✅ Sanitization cleans data before it's processed. Both are essential because we should never trust incoming user input. 🔹 Validation vs Sanitization - Consider this email: " user@mail.com " The email is technically valid, but storing it with extra spaces can cause authentication and lookup issues later. Similarly, users might submit unexpected or even malicious input. That's where sanitization comes in. 🔹 What is Sanitization? Sanitization transforms incoming data into a safer and cleaner format before it reaches business logic or the database. Some common examples: • Remove unnecessary whitespace • Escape potentially dangerous characters • Normalize email addresses • Convert values to expected types The goal is to ensure the application works with clean and predictable data. 🔹 TDD Approach Following the Red → Green → Refactor cycle: 🔴 Red Write a failing test: • Send a registration request with spaces around the email address Example: " user@mail.com " Expected: The stored email should be: "user@mail.com" The test failed because the spaces were being saved in the database. 🟢 Green Add a sanitizer using Express Validator: trim() Now the email is automatically cleaned before reaching the controller. Run tests again → Pass ✅ 🔹 Useful Express Validator Sanitizers A few sanitizers I discovered: ✅ trim() Removes leading and trailing whitespace. ✅ escape() Converts potentially dangerous HTML characters into safe entities to help prevent XSS attacks. ✅ normalizeEmail() Normalizes email formatting. ✅ toInt() Converts values into integers. Express Validator provides many more utilities depending on the use case. 🔹 Why Sanitization Matters Without sanitization: ❌ Inconsistent data ❌ Unexpected application behavior ❌ Security vulnerabilities ❌ Poor user experience With sanitization: ✅ Cleaner database records ✅ Safer applications ✅ Consistent user data ✅ Fewer edge cases 🔹 Additional Validation Exercises The lesson also highlighted several common registration validations: • Missing first name • Missing last name • Missing password • Invalid email format • Password shorter than 8 characters • Consistent validation error responses These are great examples of requirements that can be implemented through tests first and validation rules second. 💡 Biggest takeaway Validation tells us whether data is acceptable. Sanitization ensures the data is safe and consistent. Both should work together. TDD makes it easier to verify that these rules continue working as the application evolves. @codersGyan #TDD #ExpressValidator #NodeJS #ExpressJS #TypeScript #BackendDevelopment #WebDevelopment #SoftwareEngineering #InputValidation #Security #LearningInPublic #APIDevelopment

Hey guys, I built Odos. Odos is an interactive terminal toolkit for backend developers. It helps you create, inspect, and evolve backend APIs from a local TUI instead of manually wiring the same boilerplate again and again. Install/run it: npx @levython/odos Or install globally: npm install -g @levython/odos odos What Odos helps with: - Create backend projects through a guided terminal UI - Generate Express TypeScript Prisma APIs - Add routes, models, CRUD, validation, tests, and docs - Keep backend structure tracked through odos.config.json - Preview diffs before files are written - Run project health checks - Run security checks - Generate Docker / Compose / CI deployment assets - Use a dashboard-style workflow directly inside your terminal The current stack is focused on: - Node.js - TypeScript - Express - Prisma - Zod - Vitest - Supertest The goal is simple: make backend development faster without hiding the code from you. Most generators are one-shot tools. Odos is meant to be a local backend control center. You can create a project, come backlater, add routes, add models, generate CRUD, run checks, and keep evolving the API from the same terminal workflow. If you build APIs with Node.js, TypeScript, Express, Prisma, or CLI tools, try it out: npx @levython/odos Published under @levythonhq. #BuildInPublic #OpenSource #DevTools #BackendDevelopment #NodeJS #TypeScript #ExpressJS #Prisma #CLI #TerminalUI #APIDevelopment #SoftwareEngineering #WebDevelopment #IndieDev
