General

can i actually take webshot of a webpage then email it using nodered? i did try to use the webshot palette...but it keep on crashing whenever i trigger it. Crashing means.....i will be logout from my Node-RED

If a node crashes Node-RED you really need to tell the author (usually by opening an issue on the nodes github page) so that it can be fixed.

There is also the nbrowser contrib node which you can find and read the readme on glows.nodered.org

haha, interesting idea for a website :wink:

However, flows.nodered.org might give some better results for now. :smile:

To get more information run

node-red-stop
node-red-start

in a terminal, then trigger the node. You can post the resulting output here if necessary.

I can verify that the webshot node crashes and restarts Node-RED. I too am looking for a way to capture a Node-RED ui screenshot and send it, via Twilio/SMS. I've tried all 3 nodes that mention screenshots, including the one that came out today. The other two I've tried are node-red-contrib-screenshot 1.0.1 and today's version of node-red-contrib-web-page-screenshot 0.0.2. Here's the output after installing webshot and adding it to a flow:
