OPC UA Client Proxy for Node.js

The `node-opcua-client-proxy` package is a specialized module within the comprehensive `node-opcua` pure Node.js OPC UA SDK, currently at version 2.169.0. It provides functionalities for creating client-side proxies to interact with OPC UA servers, facilitating streamlined machine-to-machine (M2M) and Internet of Things (IoT) communication patterns. The `node-opcua` project maintains an active release cadence, with frequent updates focusing on stability, performance, and OPC UA specification compliance (e.g., full support for OPC UA 1.05 subtyped structures and unions). Recent releases have introduced features like advertised endpoints for Docker/NAT deployments and a global method-call interceptor API, alongside significant internal migrations from older libraries (`async`/`lodash`) to native modern JavaScript. Key differentiators include its robust TypeScript support, comprehensive certificate management capabilities, and continuous optimization for memory and throughput, particularly in its secure channel and transport layers. This specific module is designed to provide a structured and potentially higher-level abstraction for client interactions with the OPC UA address space, simplifying common operations.
