A command line scaffolding tool for building Launch extensions.

For more information regarding Launch, please visit our product website.


To use this project you will need to have Node.js installed on your computer. After you download and install Node.js you will also have access to the npm package manager for JavaScript. Your npm version will need to be at least 3.0.0. You can check the installed version by running the following command from a command line:

npm -v

After you have installed Node.js on your machine, you will need to initialize your project. Create a folder for your project if you don't already have one. Inside the folder, run

npm init

You will need to provide the information requested on the screen. After this process is complete, you should have a file called package.json inside your folder.

You will then need to install @adobe/reactor-scaffold and save it in your project's devDependencies by running

npm install @adobe/reactor-scaffold --save-dev


Run node_modules/.bin/reactor-scaffold from the command line within your project's directory. From there, just follow the prompts. You may run the scaffold tool multiple times to add additional functionality to your extension.

Rather than type the path to the reactor-scaffold script each time you would like the run the tool, you may wish to set up a script alias by adding a scripts node to your package.json as follows:

  "scripts": {
    "scaffold": "reactor-scaffold"

Once this is in place, you may then run the tool by executing the command npm run scaffold from the command line.
