This video provides a comprehensive guide for beginners on building AI agents using n8n, a low-code/no-code automation tool. The tutorial covers the fundamentals of n8n, explains the differences between automations and agents, and walks viewers through building a weather reporting agent step-by-step.
The video uses ChatGPT to generate JavaScript code for a code node within the n8n workflow. The prompt given to ChatGPT is: "Create an n8n code node that parses this weather JSON and returns a message with: In Chicago, the high today is [high temperature], the low today is [low temperature]." The weather JSON refers to the data structure received from the OpenWeatherMap API call (via the HTTP request node). ChatGPT then generates the JavaScript code that extracts the high and low temperatures from this JSON data and formats them into a custom message string.
