Follow along in this new developer series video as Terry Orchard guides you through storing and passing data in a Node-RED flow.

What if you need to snapshot a message from a very specific part of a Node-RED flow?

For those of you who've been using the Node-RED programming tool or are just getting started, Terry's latest video provides some guidance on storing data. In a Node-RED flow, each node can add to, modify, or delete data in different ways.

You might need this data to:

• use in an entirely different flow
• compare it to another value
• prevent something from being overwritten
• save it for future reference

How do you do this?

Watch and learn the fast, easy way to store data by using the Context Storage feature in Node-RED.
