Architecture Guide: Tools, Standards & Engineering Best Practices

1. Real-Time Client-Side Validation (JSON/YAML/XML)

Formatters run isolated in WebAssembly/Web Workers, guaranteeing zero latency and 100% privacy with no server transmission.

2. Regular Expressions (RegEx) & AST Parsing

Inspect match groups, tokens, and flags interactively with real-time feedback and explanation engine.

3. Cryptographic Security & JWT Claims

Inspect payloads, token expiration, and verify RS256/HS256 signatures with client-side Web Crypto API.

FAQS & ARCHITECTURE SPECS

Q: Are my tokens or source data sent to any remote server?

A: No. 100% of computation executes entirely in your browser using Web Workers and the Web Crypto API.

Q: Can it handle multi-megabyte files without lag?

A: Yes. Heavy compute operations are offloaded to background threads so your browser UI stays silky smooth.
