💡 What is N8N?

n8n stands for “Node-based Workflow Automation Tool”, and as the name suggests, it’s a tool that helps you easily automate complex workflows by connecting different services and APIs through a visual interface based on Nodes. It’s a type of low-code/no-code platform, but it’s different in that its open source nature allows for a much deeper level of customization and control.

Its biggest feature is that it supports self-hosting, which means you can install and run it on your own server, giving you data sovereignty and reducing your dependence on service providers.

🌟 Why Choose N8N?

There are many automation tools on the market, but n8n has a special place in our hearts because of the following powerful advantages

1. Open Source Power 🚀**

   • n8n is an open source project under the MIT license, which means that anyone is free to check, modify, and distribute the code. You’re not locked into a specific vendor and have unlimited flexibility to extend or customize the functionality as needed. It’s also constantly evolving with an active community of developers around the world.

2. On-premise/Self-Hosting 🔒.

   • Unlike most cloud-based automation services, n8n can be installed and run on your own server, VPS, or even on your local computer. This is especially important for businesses that need to meet security and compliance requirements, without entrusting sensitive data to an external service. Your data is under your control.

3. Infinite Flexibility ✨

   • In addition to hundreds of built-in integrations, n8n can connect with almost any web service via HTTP requests. It even provides nodes that can execute JavaScript code, allowing you to implement complex data processing or specific business logic yourself. Beyond simple connectivity, this allows for truly customizable automation.

4. Strong Community 🤝

   • As an open source project, n8n has an active community. With an official forum, Discord channel, and more, users can ask questions, share solutions, and get new ideas from each other. This is a great help when you’re having trouble solving a problem on your own or want to learn a new feature.

5. Cost-Effectiveness 💰.

   • It’s basically free to use and doesn’t require any additional fees other than the cost of running the server. If you run a large workflow or need to handle a lot of tasks, it can save you a lot of money in the long run when compared to paid software as a service (SaaS) automation tools.

🛠️ N8N’s core features.

n8n offers a wide range of features to help you build complex workflows efficiently.

• Node-Based Interface (N8N) 🎨

  • At the core of n8n is an intuitive node-based drag-and-drop interface. Each node represents a specific service (e.g. Slack, Google Sheets, CRM) or a specific function (e.g. data transformation, conditional branching), and you can connect them to visually organize the flow of your workflows.

• Diverse Triggers & Actions (Diverse Triggers & Actions) 🔗

  • Workflows are initiated by specific events (triggers). N8N supports a wide variety of triggers, including Webhooks, Scheduler, receiving an email, changing a specific database, etc. It also provides pre-built nodes (Actions) for hundreds of services to easily send data or perform actions.

• Data Transformation & Processing ⚙️

  • *Data passed through workflows often requires transformation or cleansing. n8n provides powerful capabilities to parse, filter, merge, and complexly process data in various formats such as JSON, XML, and more using custom code.

• Error Handling 🛡️

  • *Errors are bound to happen in automated workflows. N8N provides a variety of error handling options to increase the reliability of your workflows, including retry logic, sending notifications to specific channels, or running alternative workflows when an error occurs.

• Expressions & Functions 💡.

  • Expressions and Functions can be used when you want to dynamically process data or control the flow of a workflow based on specific conditions. Written in JavaScript, they allow for flexible and powerful data manipulation.

🗺️ How does N8N work? (Basic flow of a workflow)

N8N workflows basically work in the following flow.

1. Trigger (Trigger): The starting point of the workflow ➡️.

   • **Workflow starts when a predefined event occurs, such as a new email is received, an inquiry is made on your website, or a certain time is reached.
   • Example: “Every day at 9am ⏰” or “New Twitter mentions 🐦”

2. Nodes: Actions at each step 🧩

   • *A workflow initiated by a trigger goes through several nodes in sequence to perform an action. Each node is responsible for receiving data, processing it, and passing it on to the next node.
   • Examples: “Get data from Weather API”, “Filter data”, “Send Slack message”

3. Data Flow: The movement of information 🌊.

   • Each node takes as input the data processed by the previous node, performs its own task, and outputs the result to the next node. This data flow allows you to connect and automate complex tasks.
   • Example: Weather data (input) -> Filter node (processing) -> “Today’s weather in Seoul is sunny.” (output)

🌐 Real-World Use Cases

N8N offers endless possibilities for improving business and personal productivity. Here are just a few examples

• CRM/Database Synchronization:.

  • When new customer information is added to your CRM, it automatically sends a welcome email, sends a notification to your Slack channel, and records backup data in Google Sheets. 📧💬📊

• Social Media Automation:.

  • Monitor tweets with specific keywords and log them in a spreadsheet, or automatically share new blog posts to LinkedIn, Facebook, etc. when they’re published. 🐦📈

• Automate reports and alerts:**

  • Every morning at 9am, aggregate last week’s sales data into a report and email it to the right people; or, send instant alerts via SMS or Discord when your server monitoring system raises an alert. 📊📨

• Data extraction and transformation:.

  • Periodically scrape data from specific websites, remove unnecessary information, and store the refined data in a database. 🧹💾

⚔️ n8n, how is it different from other automation tools (vs. Zapier, Make, etc.)?

Cloud-based automation services like Zapier and Make (formerly Integromat) are convenient and powerful, but n8n has a few key differences

N8N is an excellent choice, especially when data security and privacy are important, or when complex and highly customized workflows are required.

🚀 Get started with N8N

Getting started with n8n is not as difficult as you might think.

1. Installation: The most recommended method is to use Docker. You can easily install and run n8n on your server with just a few lines of commands.

   docker run -it --rm --name n8n -p 5678:5678 -v ~/.n8n:/home/node/.n8n n8n/n8n

   There are many other ways to install using npm, Docker Compose, and more.

2. Accessing the UI:** After installation, connect to http://localhost:5678 (or your server IP address: 5678) in a web browser and you’ll be greeted with n8n’s clean workflow editor.

3. Create your first workflow:**

   • As a simple example, you can create a workflow that “gets the weather every morning at 9am and posts it to a Slack channel”.
   • Trigger: Use the Cron node and set it to “9am every day”.
   • Action 1: Use the HTTP Request node to send a request to a weather API (e.g., OpenWeatherMap) to get weather data.
   • Action 2: Use the Slack node to post the fetched weather information to a specific Slack channel. (You can use Expressions to dynamically include the weather data in the message content.)
   • Action 3: Connect the nodes, set up the necessary credentials, and “Activate” the workflow to start the automation!
