Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including itsa-cli with all npm packages installed. Try it out:

itsa-cli lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:

// require("itsa-cli/[??]")

This service is provided by RunKit and is not affiliated with npm, Inc or the package authors.

itsa-cli v16.5.2

Command line interface for itsa-react-server


Command line interface for itsa-server


Step 1: install itsa-cli globally:

npm install -g itsa-cli

Creating applications

Once you have all these packages, you can create a new web-application like this:

Create a new application:

itsa create appname

appname will become a new folder with all appropriate files.

Check the new application

Goto the created folder and run:

npm run watch

As soon as the message Server running development at port: 3001 appears, you can open a browser and visit http://localhost:3001. The Hello World! app should come up.

See for the complete documentation and usage.

You can start right away building your application. Any help can be found at
