- ... display data in a UI?
The flowing gif shows the usage of final flow implementation in Node-RED.
The motivation for that example project is: When I support Hackathons I notice there's often a lack of programming knowledge and building UIs. 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 to 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 this example project, which provides an example to build a simple application from scratch, which contains the main functionalities to insert data, display data in a table and search for values, as you see in the gif below.
Estimated time and level¶
|30 min||beginners||(option 1) build flow absolute beginner from scratch|
|10 min||beginners||(option 2) import existing absolute beginner flow|
After the setup of the example 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 diagram shows the simplfied architecture of the example Node-RED application.
You should have a ...
- ... free IBM Cloud Lite Account
- ... running Node-RED instance on IBM Cloud created with a pre-configured Node-RED App.
