npm (scoped)

This project provides a sandbox in which you can manually test your Launch extension. You can test both (1) your views that will eventually appear in the Launch application and (2) your library logic that will eventually run on the user's website.

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

Installing the Sandbox

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 both @adobe/reactor-turbine and @adobe/reactor-sandbox and save them in your project's devDependencies by running

npm install @adobe/reactor-turbine @adobe/reactor-sandbox --save-dev

Running the Sandbox

To run the sandbox, run node_modules/.bin/reactor-sandbox from the command line within your project's directory. A server will be started at http://localhost:3000. If you navigate to that address in your browser, you will see the view sandbox which allows you to test your views. You'll need to have previously created a view in your extension for it to show up in the sandbox. You can switch between views you would like to test using the controls toward the top of the page.

You may also click on the "Go to library sandbox" button at the top-right of the page to navigate to the library sandbox where you can test your library logic. See Configuring the Sandbox for how to configure the library sandbox for proper testing.

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

  "scripts": {
    "sandbox": "reactor-sandbox"

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

Configuring the Sandbox

To configure the portion of the sandbox that allows you to test your library logic, you'll want to run node_modules/.bin/reactor-sandbox init (Mac/Linux) or node_modules\.bin\reactor-sandbox init (Windows) from the command line within your project's directory. This will generate a directory within your project named .sandbox that contains two files you may edit to configure the sandbox:

  • container.js When Launch publishes a library, it consists of two parts: (1) a data structure that stores information about saved rules, data elements, and extension configuration and (2) an engine to operate on such a data structure. container.js is the data structure (not the engine) that you may modify to simulate saved rules, data elements, and extension configuration. This template will be used to produce a complete container.js (JavaScript from your extension will be added) which will be used in tandem with the Turbine engine inside the sandbox. If you need help understanding how to modify container.js for your needs, please let the Launch team know and we can help you out.
  • libSandbox.html includes some simple HTML along with script tags to load a complete container.js and the Turbine engine. libSandbox.html can be modified to manually test whatever you would like. For example, if you're testing that your awesome new "focus" event feature works, you can add a text input to the web page to ensure your dummy rule fires when a form element receives focus.
