n8n The Ultimate Course

Master looping and iteration in n8n by processing each list item, splitting full names into first and last names, and performing conditional outreach to past customers.

Explain the difference between persistent data stored on disk or a database and non-persistent data kept in memory, which disappears when power is off.

Explore JSON through a spreadsheet analogy, learning keys, values, and nested objects like address, plus arrays and zero-based indexing, with n8n and N810 drag-and-drop expressions.

Explore how webhooks and APIs form endpoints, implement get and post methods, and design back end processing with authentication, testing, and data flows to Google Sheets using n8n.

Learn how triggers start your n8n workflows and how actions carry out tasks, with real-world examples using google sheets, sql server, and webhooks to move and manage data.

Execute a command on the host from a container and understand why, using Docker Desktop on Windows 11 with Linux fundamentals and commands like pwd and ls.

Discover how the execution data node captures extra metadata for each workflow execution, stores it as custom metadata, and enables focused reporting and queries in SQLite or Postgres.

Explore the forms node in n8n, its role alongside respond to webhook, and recognize its place among core nodes in this course.

Explore the flow nodes in n8n, starting with a trigger node, then the filter node, as you learn about branch, loop, and merge concepts and preview core nodes.

Learn how to filter lists in n8n using the filter node, with exact-match versus contains logic in Google Sheets, including cascading filters and limitations on complex groupings.

Explore how the if node can filter data and trigger actions in one step, nest conditions, and cascade and/or logic to control true and false paths.

Explore how the execute sub workflow is delivered as a facade video that points to the core video, with a duplicate item under the flow in section four.

Explore how the stop and error node handles failed workflows, switch to an error output, and route errors to a system error handler or error workflow with alerts.

Watch the facade video for the code node and follow the linked sections to access the full-length video detailing the code node.

Learn how to use the n8n date time node to get the current date, format dates, adjust date values, and handle time zones.

Explore the filter concept through a placeholder video that directs you to the official full length video in the description.

Limit data by requesting only a top x number of items, as shown with select top ten, to avoid extra work and enable batch processing.

Learn how to remove duplicates in n8n using the remove duplicates and compare data sets nodes, with a focus on deduplicating by email, keeping new items, and handling fields.

Explore how the markdown node converts HTML to markdown, producing minimal output for retrieval augmented generation and stripping HTML noise. Use an I node or AI styling to improve formatting.

Rename keys in the data transformation node to map customer name, customer email, customer phone number, and ID, with data untouched and noting SQL alternatives.

Sort data in n8n using order by to arrange by customer id or customer name in descending order, and compare sort node with the code node for flexible transformations.

Master string manipulation in n8n with replace all, split, trim, base64, and URL encoding to clean and extract URLs from RSS feeds and Google Alerts.

Learn how to create an RSS feed from Google Alerts in n8n, cast the publish date from string to date time, and compute the difference with diff two in days.

Build and test an n8n chatbot using a chat message trigger and developer mode, then deploy publicly, exploring AI agents, a basic LM chain, and memory context for conversations.

Learn how the model context protocol (MCP) works as a server and client toolbox of tools and workflows, from calculators to AI components, with security considerations for production.

Understand model quantization, parameters, and context lengths, and learn how memory and gpu constraints shape loading 17b or 70b models, with Q4, K, and M quantization notes.

Install node with brew on mac or MSI on Windows, then install n8n via npm. Run in docker for use, or Windows service with NSSM, or mac launch agent.

Install easy panel on Linode, deploy containers via Docker or repos, configure domain with https and Let's Encrypt, and manage continuous integration and delivery for scalable hosting.

Discover how to locate and configure environment variables in n8n, including Postgres and SQLite considerations, hosting with easy panel and Supabase, and key notes on endpoints, logs, and deployments.
