Release v1.48.0

🚀 New Features

🔹 Unified Token-Bucket Rate Limiter for HTTP Clients

GoFr introduces a brand-new, pluggable rate limiter that works across all HTTP client calls.

Key Highlights:

• Supports in-memory and Redis-backed stores
• Simple drop-in integration via RateLimiterConfig or AddOption
• Integer-only token bucket with burst support
• Background cleanup for local buckets
• Customizable request grouping using KeyFunc

Why this matters:

• Ensures consistent throttling across all downstream HTTP services
• Distributed apps can now safely rate-limit using Redis

Additional Details :

• Default limit: 60 req/min, burst 10
• Returns RateLimitError (429) with RetryAfter for easy handling.

📦 Improvements

🔹 HTTP Client Enhancements with Rate Limiting

• Rate limiter now acts as an HTTP wrapper, intercepting all Get/Post/Put/Delete calls (including header variants)

• Service key normalization improved via default keying (scheme://host)

• Cleaner validation through RateLimiterConfig.Validate() with automatic sane defaults

🔹 SQL Operation Normalization

• SQL operation detection now always returns UPPERCASE keywords. Improves reliability for middleware and query inspection logic.

🔹 OAuth Token URL Validation Cleanup

• Switched to shared scheme constants (http / https). Reduces duplicated literals and improves code clarity

🐛 Bug Fixes & Small Changes

🔹 Consistent SQL Operation Detection

• getOperationType() now normalizes to uppercase, preventing case-sensitivity issues across modules

🔹 Documentation Updates

• HTTP communication guide adds all details to add rate-limiter in your registered HTTP Services. Added examples for:
  • In-memory usage
  • Redis-backed multi-instance usage
  • Custom keying functions
• Added Documentation to setup gRPC Streaming Services/Clients using GoFr.
