Development Best Practices

Essential tips and techniques to improve your development workflow and code quality.

๐Ÿ“„

JSON Best Practices

Follow JSON formatting standards for better readability and API compatibility.

{ "name": "John Doe", "age": 30, "skills": ["JavaScript", "Python", "React"], "active": true }
๐Ÿ”

Password Security

Generate strong passwords with mixed characters and adequate length for security.

โ€ข Minimum 12 characters โ€ข Mix uppercase, lowercase, numbers, symbols โ€ข Avoid dictionary words โ€ข Use unique passwords per service
๐Ÿ†”

UUID Usage Guidelines

Choose the right UUID version for your specific use case and requirements.

UUID v1: Timestamp-based (contains MAC address) UUID v4: Random (most common, cryptographically secure) UUID v5: Namespace-based (deterministic)
โšก

Code Formatting Standards

Maintain consistent code formatting for better readability and team collaboration.

โ€ข Use 2-4 spaces for indentation โ€ข Keep lines under 80-120 characters โ€ข Use meaningful variable names โ€ข Add comments for complex logic
๐Ÿ“ฑ

QR Code Optimization

Design QR codes for maximum scannability and user experience.

โ€ข Use high contrast colors โ€ข Maintain quiet zone around code โ€ข Test on various devices โ€ข Keep data concise for better scanning
๐Ÿ”—

Hash Function Selection

Choose appropriate hash functions based on security requirements and use cases.

MD5: File integrity (not cryptographically secure) SHA-256: Digital signatures, certificates bcrypt: Password hashing HMAC: Message authentication

Frequently Asked Questions

Common questions about development tools, code formatting, and best practices.

JSON formatting beautifies and structures the code for readability, while validation checks syntax correctness and identifies errors. Both are essential for working with JSON data effectively.
Yes, our password generator uses cryptographically secure random number generation (CSPRNG) to create passwords that are unpredictable and suitable for security-critical applications.
Use UUID v4 for most applications as it's random and doesn't leak information. Use UUID v1 only when you need timestamp ordering and don't mind exposing MAC address information.
QR codes are not encrypted by default and can be read by anyone. For sensitive data, encrypt the information before encoding or use QR codes only as references to secure systems.
No, MD5 is not secure for passwords due to collision vulnerabilities and speed. Use bcrypt, scrypt, or Argon2 for password hashing instead. MD5 is still acceptable for file integrity checks.
Yes, most tools process data client-side in your browser and work offline once loaded. This ensures privacy and security as your data never leaves your device.
While these are web-based tools, you can bookmark them for quick access. For CI/CD integration, consider using command-line equivalents of these tools in your build processes.
Most tools can handle files up to 10MB. For larger files, consider breaking them into smaller chunks or using specialized tools designed for big data processing.
