npmove 0.0.2

Small CLI to move, back up, and diff n8n workflows between instances.

npmove

Small command-line tool to move, back up, and diff n8n workflows between instances.

npmove talks to the n8n REST API. It is useful when you have more than one n8n instance (typical setup: dev / staging / prod) and you want to keep workflows in sync without clicking through the UI or hand-editing exported JSON.

Install

pip install npmove

Python 3.9+ required.

Quick start

Save credentials for an instance (do this once per server):

npmove auth dev   https://dev.n8n.example.com  --token <api-token>
npmove auth prod  https://n8n.example.com      --token <api-token> --default

List workflows on the default instance:

npmove list
npmove list --active

Test string for example Export a single workflow to stdout:

npmove export 42

Export a single workflow to a file:

npmove export 42 -o workflows/my-flow.json

Export every workflow to a directory (one JSON per workflow, named <slug>.<id>.json):

npmove export --all -o ./backups/

Import a workflow onto another instance:

npmove import workflows/my-flow.json --instance prod

Optionally rename on import:

npmove import workflows/my-flow.json --instance prod --name "My Flow (prod)"

Compare a local file with the remote version (auto-match by workflow name, or pass --id):

npmove diff workflows/my-flow.json --instance prod

diff exits with status 1 if there are differences — handy for CI checks.

Commands

Command	Purpose
npmove auth <name> <url> --token <token>	Save instance credentials
npmove instances	List configured instances
npmove forget <name>	Remove an instance
npmove list	List workflows on the configured instance
npmove export <id>	Export one workflow
npmove export --all -o <dir>	Export every workflow
npmove import <file>	Create a new workflow on the instance
npmove diff <file>	Compare local file with the remote workflow

Run npmove <command> --help to see all flags.

Where credentials are stored

Default location: ~/.npmove/config.json (the file is chmod-600 on POSIX). You can override the directory with the NPMOVE_HOME environment variable.

The file holds plain text tokens — treat it like any other dotfile that contains secrets.

What npmove import does (and does not)

It creates a new workflow on the target instance. It does not overwrite an existing one by name or id. If you need to overwrite, delete the target workflow first (DELETE in the n8n UI or via the API), then import.

Server-managed fields (id, versionId, createdAt, updatedAt, meta.instanceId, ...) are stripped before the create call — n8n assigns them.

Limitations

• Credentials inside workflows are not transferred — n8n does not expose secrets via the workflow API, by design. After import, re-link credentials in the n8n UI.
• The tool currently supports the standard self-hosted n8n REST API (/api/v1/...). n8n Cloud uses the same shape, set the --url accordingly.
