I have watched so many of your videos and they are fantastic. When I need to figure something out I will search KZfaq and scroll through the other videos until I see your example. So helpful!

Finally a wonderful and straightforward explanation about context. I really appreciated this tutorial as it helped me conceptualise some approaches I can take to manage data in my flows more effectively. Cheers for that 😀

When using the 'Change' node, can you set a default value? I think we are missing that feature?

Great explanation, but if the node red restarts, do we still have everything saved?

what is the size of context? I could not find any numbers

@developeropto2292 Жыл бұрын

Context payloads are stored to your file system, so it depends on the file storage space of the computer that Node-RED is running on. (But you can also store context to memory, so you should think about how you want to set context up in the settings.js file).

@arssandaar Жыл бұрын

@@developeropto2292 thanks for the prompt response. I checked ~/node-red/ directory, there is no my data. Where to find them and how to check what settings are set by default. It should be known because I did not set anything specific. Is there decent documentation where things are written properly?
