[ANNOUNCE] node-red-contrib-jsontohtml

[BartButenaers]

Hi folks,

I was re-installing one of my Raspberry devices, and I found some custom nodes on it that were about 95% finished. I have such nodes lying around all over the place. It it is a very bad habbit. I should reserve some time to finalize the last 5% instead of starting with something new ...

Anyway I have quickly published one of those nodes on NPM ( ):

This node-red-contrib-jsontohtml node allows you transform a Javascript object to HTML, based on a specified transformation.

On the readme page you can find an example, where I inject an object (containing the statusses of various sensors):

Which is then transformed to HTML.
This allows me to show a popup dialog in my Node-RED dashboard very easily:

Have fun with it!!

Errr why wouldn't I just use a template node ?

[BartButenaers]

@dceejay

Errr

That sounds not like a motivational contribution speech...

Do you mean to write the html manually in a template node? Or is there perhaps a standard way to convert json to html, which I'm not aware of?

[dceejay]

Yes - that is exactly what the template node has been doing for the last 6 years...

OMG...
Never seen this kind of functionality before ...
I will put your example on my readme page, and explain that is the standard way to go...
Thanks for the example!

.... w do warn folk to discuss things here before diving in and writing loads of code... ah well as long as you enjoyed yourself.

[BartButenaers]

This must be one of my first custom nodes. Have used it since I started with Node-RED, and never have seen something similar passing by in the discussions that I follow. So it hasn't come up my mind that there was anything to discuss about it ...

Anyway I have updated the readme:

And added your example:

It now looks more like a advertising brochure for the Template node

:-). Stick to SVG goodness.
