Feature Overview

AWS IoT Integration

• AWS Iot Ready — Bring your own cloud.
• Capture device data and export to AWS.
• Send control plane data to AWS IoT shadows.
• Send structured device data to AWS DynamoDB / MongoDB.
• Stream volume device data to AWS S3 data lake or Kinesis.
• Store device logs, metrics in AWS CloudWatch.
• Keep an audit trail in CloudTrail.

MQTT Client

• MQTT 3.1.1 support.
• TLS encryption with ALPN over port 443.
• Supports connect, publish, subscribe, ping and disconnect messages.
• Message quality of service for reliable delivery.
• Retained messages.
• High message throughput with exceptionally low overhead.
• Wait for delivery or acknowledgement options.
• Auto reconnect.
• Parallelism via fiber coroutines.

HTTP Server

• HTTP/1.0, HTTP/1.1 support.
• TLS/SSL 1.3 and Alpn support.
• URL actions that bind URLs to C functions.
• Configurable request routes and redirections.
• Supports transfer chunk encoding to preserve keep-alive.
• Cookie and session management.
• Authentication and user management.
• Request tracing for HTTP request and response headers.
• Sand-box resource limits.
• Runtime configurable via JSON config files.
• HTML helpers for encoding, decoding and escaping content.
• JSON parser and query engine.
• Single-threaded, fiber coroutine event-based runtime.

Safe Runtime

• JSON parser and renderer.
• JSON query engine.
• Fiber coroutines for non-blocking procedural programming model.
• Global memory error handler.
• Logging framework —— filter by source and/or message type.
• Safe strings, lists, hashing and buffer management.
• Portable, cross-platform O/S abstraction.

Performance

• Tiny memory footprint. Web server component is 25K code. All-up is 96K code.
• Single-threaded fiber coroutines provide an elegant, non-blocking, procedural programming paradigm without resorting to clumsy callbacks or complex threads.
• Web server request throughput (> 9,300 requests per second on Raspberry PI 4).

Security

• Sandbox limits.
• Safe portable runtime to protect against memory leaks and buffer overflows.
• Transport Layer Security (TLS/SSL).
