To build a secure Node.js API for Raspberry Pi GPIO control, implement REST endpoints with Basic Auth over HTTPS, input validation, rate limiting, and IP filtering to ensure only authorized local network traffic can access your hardware.

You can run a Node.js backend on a Raspberry Pi Zero W by applying performance optimization techniques tailored for low-resource devices, ensuring your application design remains mindful of the limited CPU and RAM constraints.

The best way to secure REST APIs interacting with IoT hardware is to enforce HTTPS, configure IP filtering, apply rate limiting, and require robust authentication to prevent unauthorized access to your physical devices.

Deploying a Node.js application on Raspberry Pi using systemd involves creating a service file to manage your backend process, ensuring it runs continuously in the background and automatically restarts upon system reboots or failures.

Your Raspberry Pi REST API needs input validation and rate limiting to protect resource-constrained hardware from malicious payloads and abusive request volumes, ensuring stable performance and preventing system crashes.

Yes, you need HTTPS to expose Raspberry Pi GPIO pins over a local network to encrypt communication and secure Basic Auth credentials, preventing unauthorized interception of control commands and sensor data.
