Simple File-Based Key-Value Store (GetKey)

Read a value by key from a local JSON file. Related workflow: [WriteKey](https://n8n.io/workflows/1407) Create a subfolder in your n8n home directory: `/home/node/.n8n/local-files`. In Docker, look at the data path and create a subfolder `local-files`. Set the correct access rights: `chmod 1000:1000 local-files`. Put the workflow code in a new workflow named `GetKey`. Create another workflow with a `function item`: ```js return { file: "/4711.json", // 4711 should be your workflow id key: "MyKey", default: "Optional returned value if key is empty / not exists" } ``` Pipe the `function item` to an `Execution Workflow` that calls the `GetKey` workflow. It would be nice if we could get someday a shiny built-in n8n node that does the job. :)
