What is Hyperledger Composer Playground Server?

✍: FYIcenter.com

A

Hyperledger Composer Playground Server is a Web server that allows you to run and control your own Hyperledger Composer Playground.

Hyperledger Composer Playground Server is included in the Hyperledger Composer tool set. It is normally installed as part of your Hyperledger Composer developer environment.

When Hyperledger Composer Playground Server is running, you can:

Connect to the Playground Server with a Web browser.
Create, modify and test business networks with Hyperledger Fabric simulator running in the browser.
Create, modify and test business networks with Hyperledger Fabric developer environment running on your local computer.

You can still access the Playground Server provided at composer-playground.mybluemix.net. But that server will not provide you access to business networks hosted on your Hyperledger Fabric developer environment.
