I'm looking for solution on how can i append to a pdf file. The output 'file' of HTML-PDF node generate a new file every time i insert new line. The output "buffer" /"stream" save only the first insert. Is it possible to append pdf file in node-red. And thanks in advance.

Maybe you would get some more help if you post your flow here instead of starting a new topic for the same question over and over again. See How to share code or flow json

[{"id":"7a388eef.f3624","type":"tab","label":"Flow 6","disabled":false,"info":""},{"id":"4ce45511.318b7c","type":"ui_template","z":"7a388eef.f3624","group":"1dc1526e.1e610e","name":"","order":0,"width":0,"height":0,"format":"<style>\n /* The Modal (background) */\n body {font-family: Arial, Helvetic…

Please provide a flow that we can test to see the problem. Use inject node(s) to simulate inputs. I cannot test the one you have provided as it just keeps asking me in French for something and won't accept what I enter.

I'm sorryabout that. Here's an exemple with inject [{"id":"594ba9a8.b17d38","type":"inject","z":"9e3de0fc.322e9","name":"","topic":"","payload":"hello","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":110,"y":240,"wires":[["b6b117ea.7a2388"]]}]

You have posted a flow with only one node - an inject node. Nothing else.

Sorry again. [{"id":"95d073fd.2cb84","type":"tab","label":"Flow 18","disabled":false,"info":""},{"id":"d35461.7e881ba","type":"file","z":"95d073fd.2cb84","name":"","filename":"","appendNewline":true,"createDir":true,"overwriteFile":"false","x":550,"y":180,"wires":[[]]},{"id":"185d10ab.0a440f","type…

When I click an inject it creates the file of size 6167 bytes. When I click it again it doubles in size to 12330, and gets bigger each time I click an inject. It is not overwriting the file each time. Have you checked the file size on your system?

yeah i have checed it but the content still the same from the first inject.

What size file are you seeing after one and two injections?

one inject 7 KB , two inject 13 KB.

If you're trying to collect data over an unspecified period you should consider to put that data into a database first (sqlite for example) and add a "Generate PDF"-button" which selects the wanted data from the database and writes it to a PDF at once.
