Using the Node Dev CLI#

Using the Node Dev CLI makes sense if you do not want to ever share the node that you create. For example, for internal systems or something very specific to your internal tooling. Also, the CLI only works if there are no additional dependencies required by the node as it does not support installing additional node modules.

If that is not the case, it is best to do follow the creating your first node tutorial or create your own custom node-package.

Create the first basic node#

  1. Install the WF²-node-dev CLI: npm install -g WF²-node-dev
  2. Create and go into the newly created folder in which you want to keep the code of the node
  3. Use CLI to create boilerplate node code: WF²-node-dev new
  4. Answer the questions (the “Execute” node type is the regular node type that you probably want to create). It will then create the node in the current folder.
  5. Program… Add the functionality to the node
  6. Build the node and copy to correct location: WF²-node-dev build That command will build the JavaScript version of the node from the TypeScript code and copy it to the user folder where custom nodes get read from ~/.WF²/custom/
  7. Restart Doc² and refresh the window so that the new node gets displayed

Create own custom WF²-nodes-module#

If you want to create multiple custom nodes which are either:

  • Only for yourself/your company
  • Are only useful for a small number of people
  • Require many or large dependencies


To learn how to develop and test WF²-nodes-module, refer to the Create WF²-nodes-module documentation.

It is best to create your own WF²-nodes-module which can be installed separately. That is an npm package that contains the nodes and is set up in a way that Doc² can automatically find and load them on startup.

When creating such a module the following rules have to be followed that WF² can automatically find the nodes in the module:

  • The name of the module has to start with WF²-nodes-
  • The package.json file has to contain a key WF² with the paths to nodes and credentials
  • The module has to be installed alongside WF²

An example starter module which contains one node and credentials and implements the above can be found here:²-io/WF²-nodes-starter

Setup to use WF²-nodes-module#

To use a custom WF²-nodes-module, it needs to be installed alongside Workflow². For example like this:

# Create folder for Doc² installation
mkdir my-WF²
cd my-WF²

# Install WF²
npm install WF²

# Install custom nodes module
npm install WF²-nodes-my-custom-nodes

# Start WF²

Development/Testing of custom WF²-nodes-module#

This works in the same way as for any other npm module.

Execute in the folder which contains the code of the custom WF²-nodes-module which should be loaded with WF²:

# Build the code
npm run build

# "Publish" the package locally
npm link

Then in the folder in which Doc² is installed:

# "Install" the above locally published module
npm link WF²-nodes-my-custom-nodes

# Start WF²
