n8n - An open-source workflow automation platform that supports over 400 applications and allows drag-and-drop creation of complex workflows.

What is n8n?

n8n is an open-source, low-code AI workflow automation tool built on Node.js. Through a visual interface, users can easily build automated processes by dragging and dropping nodes, each representing an action or trigger. n8n supports integration with over 400 services, including Slack, Google Sheets, Notion, and more, and allows for custom code to meet complex needs. n8n's core advantages are its open-source and free nature; it can be used for personal and non-commercial purposes without restrictions on data privacy and supports self-hosted deployment. Suitable for both businesses and individuals, it can automate tasks such as handling customer inquiries and posting on social media. n8n offers flexible deployment options, installable via npm, Docker, or binaries.

Main functions of n8n

• Visual workflow buildingBuild automated workflows by dragging and dropping nodes. Each node represents an operation or trigger, enabling process automation without complex programming.
• Rich service integrationIt supports integration with over 400 services, covering common applications and data sources such as Slack, Google Sheets, Notion, and Airtable, making it easy for users to connect to various tools and platforms.
• Custom code supportAllows users to write JavaScript or Python code in nodes to implement more complex logic and functions, meeting personalized needs.
• Self-hosted deploymentUsers can deploy n8n themselves to ensure data privacy and security, and can customize and expand it according to their needs.
• Flexible triggering methodsIt supports various triggers, such as timed triggers and event triggers, and allows you to flexibly set the workflow startup conditions according to different business scenarios.
• Powerful data processing capabilitiesIt can handle various types of data, including text, numbers, and files, and supports data conversion, filtering, and mapping operations.
• Collaboration and management functionsIt supports team collaboration, allowing users to share workflows, set permissions, and provides features such as workflow version control and execution logs for easy management and maintenance.

How to use n8n

• Installation and DeploymentIt can be installed globally via npm, deployed via Docker, or using a binary package.
• Create a workflowAfter logging into the n8n interface, click "Create Workflow" to start building an automated process.
• Add triggerSelect the appropriate trigger node, such as timed trigger or API trigger, and set the trigger conditions.
• Add operation nodeAdd various operation nodes as needed, such as sending emails and updating the database.
• Configure node parametersConfigure specific parameters for each node, such as data source and target address.
• Connecting nodes: Connect triggers and operation nodes by dragging lines to form a complete workflow.
• Test workflowAfter saving the workflow, click the "Test" button to check if the workflow is running as expected.
• Deployment and OperationAfter successful testing, the workflow will be deployed to the production environment to automate the tasks.
• Monitoring and maintenanceUse n8n's logging and monitoring features to view the execution status of workflows and handle exceptions promptly.

n8n's technical principles

• Built on Node.jsn8n uses Node.js as its runtime environment, leveraging its efficient event-driven and non-blocking I/O model to achieve high-performance automated task processing.
• Workflow engineThrough a visual interface, users can connect different nodes (operations or triggers) to form workflows. The n8n engine is responsible for parsing and executing these workflows, running each node according to the user-defined order and logic.
• Node SystemEach node represents a specific operation or trigger, such as sending an email, reading from a database, or receiving a webhook. n8n provides a rich set of built-in nodes and supports user-defined nodes, extending functionality by writing JavaScript or Python code.
• Data Flow and ProcessingIn the workflow, data flows between nodes in JSON format. Each node can receive, process, and transmit data, and n8n provides powerful data processing capabilities, including data transformation, filtering, and mapping.
• Service Integrationn8n supports integration with over 400 external services and APIs, connecting to various applications and data sources via OAuth, API keys, and other methods to enable data interaction and manipulation.
• Self-hosted and Deployedn8n supports multiple deployment methods, including local servers and cloud platforms. Users can choose the appropriate deployment environment according to their needs and security requirements to ensure data privacy and security.
• Task scheduling and triggeringn8n provides multiple triggering methods, such as timed triggering and event triggering, which can automatically start the workflow according to preset conditions to realize automated task scheduling.
