EventumInfrastructure-grade, security-first logging for Node.js, powered by Rust.

Minimal overhead, threaded batching, and text/JSON outputs.

⚡️

Minimal overhead

Rust handles all heavy lifting with almost no impact on the Event Loop.

🧵

Efficient log batching in background threads. Log millions of messages with ease.

📝

Choose between human-readable text output with automatic coloring or exact JSON lines.

🛡️

Protect passwords, tokens, and PII with built-in sensitive data masking schemas.

🔄

Daily rotation, size-based rotation, and backup limits built-in out of the box.

🌍

Separate configs for development and production automatically applied.

Benchmarks were executed locally on a development machine. Results may vary depending on hardware and environment.
