It uses socket.io library which enables real-time, event-based communication. It shows how socket.io rooms can be used to create different chat rooms. 6 | This application can be run locally as well as on Cloud Foundry landscape. 7 | 8 | Features: 9 | * Login with name, email Id. 10 | * Chat with a user who has logged into the same chat room. 11 | * Only 2 people are allowed per room. If more people enter, they will be directed to a different room. 12 | 13 | ## Requirements 14 | - [Node js](https://nodejs.org/en/download/) 15 | - [Cloud Foundry Command Line Interface (CLI)](https://github.com/cloudfoundry/cli#downloads) 16 | - Cloud Foundry trial or enterprise account, [sign up for a Cloud Foundry environment trial account on SAP Business technology Platform(https://developers.sap.com/tutorials/hcp-create-trial-account.html) 17 | 18 | ## Download and Installation 19 | Running the application 20 | 21 | 1. [Clone](https://help.github.com/articles/cloning-a-repository/) this repository 22 | 2. Login to Cloud Foundry by typing the below commands on command prompt 23 | ``` 24 | cf api 25 | cf login -u -p 26 | ``` 27 | `api` - [URL of the Cloud Foundry landscape](https://help.sap.com/viewer/65de2977205c403bbc107264b8eccf4b/Cloud/en-US/350356d1dc314d3199dca15bd2ab9b0e.html) that you are trying to connect to. 28 | 29 | `username` - Email address of your sap.com account. 30 | `password` - Your sap.com password 31 | 32 | Select the org and space when prompted to.
