I'm developing a web server on an ESP8266 using NodeMCU firmware. What are the NodeMCU documentation's recommendations for efficiently implementing web servers, particularly concerning the device's limitations? Does it advise against directly building complex user interfaces or full HTTP web servers, and what is the suggested approach for handling more demanding tasks?
Navigate to the NodeMCU Documentation homepage (nodemcu.readthedocs.io). Navigate to the 'Lua Developer FAQ' section. Within the FAQ, find and access the 'Techniques for Reducing RAM and SPIFFS footprint' section. Read the content, specifically the 'How do I minimise the footprint of an application?' subsection, to extract key advice regarding web server implementation and resource management on the ESP8266. Synthesize the advice into a concise answer.
State that the documentation advises against implementing complex user interfaces or HTTP web servers directly on the ESP8266. Explain that the ESP8266 is an IoT device with limited scope and is not a general-purpose system. State that complex tasks, user interfaces, validation, and security should be offloaded to a more capable general-purpose system (e.g., Raspberry Pi) in a tiered approach. Mention the 'Keep It Simple Stupid' (KISS) principle in relation to scoping ESP8266 applications.
