Store and retrieve global configuration variables across workflows

Overview

This node manages global configuration variables across workflows by allowing users to set, get, delete, and clear variables stored in a shared config store. It is useful for storing environment-specific settings, API keys, or any data that needs to be reused across multiple workflows. For example, you can set a project ID once and retrieve it in different workflows without hardcoding it each time.

Use Case Examples

  1. Set a variable named APPWRITE_PROJECT_ID with your project ID to reuse in workflows.
  2. Get the value of a stored variable to use in subsequent workflow steps.
  3. Delete a variable when it is no longer needed.
  4. Clear all stored variables to reset the config store.

Properties

Name Meaning
Variable Name The name of the variable to set, get, or delete. Use uppercase for convention.
Variable Value The value to store for the variable. Supports n8n expressions. Only used when setting a variable.
Options Additional options for the operation.

Output

JSON

  • _configStore
    • operation - The operation performed (set, get, setMultiple, getAll, delete, clear).
    • variable - The variable name involved in the operation (if applicable).
    • value - The variable value, masked if marked as secure.
    • success - Indicates if the operation was successful.
    • found - Indicates if a requested variable was found (for get operation).
    • error - Error message if a variable was not found (for get operation).
    • variables - An object containing multiple variables and their values (for setMultiple and getAll operations).
    • count - The count of variables involved in the operation (for setMultiple and getAll).
    • deleted - Indicates if a variable was deleted (for delete operation).
    • cleared - The number of variables cleared (for clear operation).

Dependencies

  • Uses an internal Map object to store variables in memory during runtime.

Troubleshooting

  • If a variable is not found during a get operation, the output will indicate 'Variable not found'. Ensure the variable name is correct and has been set previously.
  • When setting a variable as secure, the value is masked in the output and logs. Make sure to handle secure variables appropriately in downstream workflow steps.
  • Clearing all variables removes all stored data; use with caution to avoid data loss.
