What API’s do you guys use to get satellite image? Preferably one with a dark theme.

n

Okay, so I I have to create another html tag or will it inherit the master?

How can I go about designing the UI for my module. Is there any site I can use as a playground to design the UI?

Thanks,

Thank you all for all your wonderful suggestions. I’m able to run my python script successfully now. Thanks!

@sdetweil Amazing. Thank you.

@sdetweil I think I see what your mean now. Can I do, for instance, something like

wrapper.innerhtml = "<h1>This is some random text</h1>"

@sdetweil after running successfully a few times it now returns Buffer 48 45 5c… or something that looks like hexadecimal code

@sdetweil So I tried putting in the full path in my node_helper as opposed to relative path and that seemed to work. is there a way I can log the current directory in nodejs. It seems that’s the issue

@sdetweil said in child_process won't execute:

node testit.js

Yes, that works in the console.

@sdetweil That is correct. It works up till that point.

@sdetweil thanks for the response. that doesn’t seem to be working either.
Is there something I need to install to be able to use stdout?

@sdetweil How can I construct ModuleName as an html?

I’m trying to execute a python script using the child_process. However my function doesn’t seem to be triggering.

const spawn = require("child_process").spawn
var NodeHelper = require("node_helper")
const process = spawn("python3", ["return_something.py"])

module.exports = NodeHelper.create({
  start: function() {
    this.countDown = 10000000
  },
  socketNotificationReceived: function(notification, payload) {
      switch(notification){
          case "DO_YOUR_JOB":
            console.log(payload)
            this.sendSocketNotification("I_DID", (this.countDown - payload))
            break
          case "RETRIEVE_DATA":
            console.log(payload)
            this.job()
            break
      }
  },
  job: function(){
    console.log("I'm trying to retrieve data")
    process.stdout.on('data', (data)=>{
      //********everything works up till here
        console.log("inside")
      var result = String.fromCharCode.apply(null, new Uint16Array((data)))
      this.sendSocketNotification("DATA_RETRIEVED", result)
    })
  }
})

Python script.

import sys

print("Hello, I'm Amira")

sys.stdout.flush()

Hello all. I’m currently trying to build a custom module. I’ve been trying to wrap my head around it for a few days but I think I finally have a decent understanding. I’m not that familiar with node.js so my question might sound stupid. I understand that the MMM-ModuleName.js pretty much passes data or documents to the main html. Is it possible to have an html file with custom html already defined, a table of data for example, load it in your MMM-ModuleName.js using nodejs, modify the contents using the elementid and then pass that to the main html? As opposed to creating the html using nodejs. Again, I’m pretty green when it comes to nodejs please forgive me.
