@jwilson5607 glad u got it working…

if I hadn’t done my own chartjs module, I would have had no clue,

@bugsounet
Thanks a lot for your kind informations.

@sdetweil Thanks Sam. Will give that a go.

@kylelamb1324 see my sample module
it’s node helper receives a message and sends one back
https://github.com/sdetweil/SampleModule

its
string identifying the message
and some buffer of data,
completely up to you, string, number, structure…

then on the receiving side u get the identifier, so you can tell different messages apart
and a pointer to the buffer sent by the sender

socket notifications are private to your module

an example use

the node_helper does not get any of the info from config.js like the modulename.js does

so, typically the first thing would be to send the this.config buffer to the node_helper

@thgmirror and there is a $HOME/.npm folder for npm, but I have no idea what all is stored there, and what needs to be persistent and not

@1BlauNitrox it’s 28 inch lcd monitor. Few years old. Don’t know the model

@SvenT the module should not update when it is suspended (hidden)

@MZ-BER lucky it’s a div table and not html table

@thgmirror it’s not ‘in an html’
it has to be loaded into a browser.

and then u have to export it correctly, and THEN you can call it ft another script.

@sdetweil ok
Thank you ❤

@bugsounet my apologies. I have deleted the post.

@banbutcher there is a little nosql db and lib in one
https://www.npmjs.com/package/nosql

@enderflop cool

key here is module name = foldername = filename = register name
and node_helper.js has to be in the same folder

@1blaunitrox said in updateDom() blocks MagicMirror:

I installed the software like in the docs show.

my script fixes little odds and ends not covered by the doc

@sdetweil It works btw

@sdetweil Yes he can also look at MMM-EasyBack to see how to do videos

@sifuhall my SampleModule has all the parts. u won’t need the helper if fetch works

@birdabirda the config.js info is provided to the modulename.js instance. this is object oriented programming

each unique instance is pointed to by ‘this’.

think of node_helper as a server. .
but it’s responses are broadcast to ALL instances.

so each instance needs to pass it’s
identifier as part of the data on each sendsocketNotifocation

then the node helper has to keep track of that and send that back as part of the response

then each modulename instance has to check to see if the response is for them.

you can store the data in a hash by
instance id.

@mumblebaj Log.log is just a wrapper for console.log, which lets mm do the loglevel settings in config.js
