Who is this workflow for? The WriteKey workflow enables you to store key-value pairs in a local JSON file within your n8n environment. This setup allows multiple keys to be managed within a single file, facilitating efficient data storage and retrieval without the need for external databases..

What does this workflow do?

  • Setup Local Storage Directory:
  • Create a subfolder named local-files in your n8n home directory (/home/node/.n8n/local-files).
  • If using Docker, locate the data path and create the local-files subfolder there.
  • Set appropriate access rights using the command: chmod 1000:1000 local-files.
  • Implement the WriteKey Workflow:
  • Create a new workflow in n8n named WriteKey.
  • Insert the provided workflow code into this new workflow to handle writing key-value pairs to the JSON file.
  • Create a Data Input Workflow:
  • Build another workflow incorporating a Function Item node.
  • Configure the Function Item node to output the desired key-value data in the following format: javascript return { file: '/4711.json', // Replace 4711 with your workflow ID key: 'MyKey', value: 'MyValue' };
  • Connect to Execution Workflow:
  • Link the Function Item node to an Execution Workflow node.
  • Configure the Execution Workflow node to call the WriteKey workflow, passing the key-value data for storage.
  • Future Enhancements:
  • Anticipate the development of a dedicated n8n node for key-value storage to streamline this process further.

🤖 Why Use This Automation Workflow?

  • Local Data Management: Maintain and access key-value pairs locally without relying on external services.
  • Simplicity: Easily store and retrieve data using straightforward JSON file manipulation.
  • Integration: Seamlessly works with existing n8n workflows, enhancing data handling capabilities.

👨‍💻 Who is This Workflow For?

This workflow is ideal for developers and users of n8n who need a lightweight solution for managing configuration settings, temporary data storage, or simple data persistence tasks within their automation processes.

🎯 Use Cases

  1. Configuration Management: Store and retrieve application settings or configuration parameters locally.
  2. Temporary Data Storage: Maintain temporary data between workflow executions without using external databases.
  3. User Preferences: Save user-specific preferences or settings in a centralized JSON file for easy access and modification.

TL;DR

The WriteKey workflow provides a straightforward method for storing key-value pairs in a local JSON file within your n8n environment. By setting up this workflow, you can efficiently manage and persist data locally, enhancing your automation processes with minimal setup and maintenance.
