NodeRun trans

is the newest Profound Logic product dedicated to making it easier for Node.js developers to create applications by moving development to a cloud-based environment. NodeRun comes with a full IDE with Visual Designer, editor, debugger, and Node.js already pre-installed. Some of NodeRun's most notable capabilities include design screens, the ability to develop and run application within the program, full debugging capabilities, the ability to install NPM packages, manage your own Node.js server, work with active sessions to see end-user activity, host database and built-in Database Explorer, a command-line terminal for full control of your space, as well as the ability to share and collaborate with other developers.

Getting started with NodeRun is quick and easy. All you need is a modern internet browser (Google Chrome, Mozilla Firefox, etc.) and that's it. Every NodeRun Space is free to build and comes with its own files, database, and server. To get started visit NodeRun.com create an account and begin developing, it's that easy!

This 8 part blog series will give you a set of exercises to help you build a Node.js applications that work with employee data. Last week we looked at how to list a web service within NodeRun, this week we are going to learn how to create a details web service.
