The motivation for that blog post is: When I support Hackathons I notice there’s often a lack of programming knowledge and building UIs, but they have awesome ideas. If this is the case, then Node-RED is a perfect starting point to realize a prototype at a hackathon. The dashboard of Node-RED is a awesome way to build a UI, but there was a “out of the box” Node missing to simply add a table. Now I found a very useful Node that’s create a table inside a Node-RED dashboard.
That’s motivated me to create an example GitHub project, which provides an example to build a simple application from scratch.
The gif shows the simple functionality of the flow.
- Enter a new user
- Search for lastname
- Inspect result
After the setup of the example you should be able to use your Node-RED instance on IBM Cloud to
- … save data in a Cloudant database within your Node-RED installation on IBM Cloud
- … search for data entries using Cloudant database query
- … display data in a UI using Node-RED dashboard and Node-RED UI Table
The following 25 min YouTube video shows the setup:

I hope this was useful for you and let’s see what’s next?

PS: By the way, you can use the IBM Cloud for free, if you simply create an IBM Lite account. Here you only need an e-mail address and for more information about IBM Cloud information sources?
