Our playground uses our less-code cloud approach. No need to create HTTP calls, just create a node.js module and call its exported functions.
Full Stack Snippets
Each time you click on the "Run" button, the Node.js module is deployed on a real physical server on the cloud (currently on Azure). All is managed for you from the deployment or accessing the backend logs to debug your code. The preview gives you the result of your frontend+backend execution right in your browser.
