MagicMirror² v2.13.0 is available! For more information about this release, check out this topic.

config.js in JSON format

  • @Serge maybe javascript-stringify npm module would help.

    Load config.js
    Json stringify
    Apply schemas
    Capture json on save
    Convert to js

    this little script seems to work

    var jjs=require('javascript-stringify')
    var cfg=require('../MagicMirror/config/config.js')
    var js=require('json-stringify')
    var js_config = JSON.stringify(cfg.config)
    console.log("var config="+jjs_config)

    JSON converting may lose some js specific features like callback function, dynamic values by condition, etc. I doubt the benefit of strict json format.
    And the user would still make mistakes to write strict JSON format.
    I can’t agree JSON is the only or better way to make user-friendly configurable web UI.

  • @Sean do you have some examples of these kinds of data elements? I’d be interested to pass them thru this simple converter to see the fidelity

  • Module Developer


    1. callback function as value;
      Many of my modules use the callback functions to make user command or user-customizable dynamic features instead to modify the source itself. (eg. filter, sort, transform, …)
      Here is the the sameple of MMM-NotificationTrigger;
      module: "MMM-NotificationTrigger",
      config: {
            trigger: "SOME_NOTIFICATION",
            fires: [
                payload: (payload) => {
                  return {
                    title:"Notification comming",
                    message: payload.someOption
    1. dynamic values;
      I manage several different configurations in one config.js for my convenience. like this;

    (simplified concept)

    const mode = "testA"
    const someValue = {
      "testA" : "testA",
      "testB" : "testB",
      "debug" : "debug",
      "release" : "release",
      module: "MMM-SOMEMODULE",
      config: {
        someField: ((mode == "testA") ? true : false),
        someField2: someValue[mode],

    The real usage is more complex but you can catch my approach.

  • @Sean thanks… the 1st, with callbacks was preserved… the 2nd, with the algorithmic values, produced the results of the algorithm… the node runtime does the algorithmic replacement on load of the file… the converter would not know. (unless it processed the text)

                            module: 'MMM-SOMEMODULE',
                            config: {
                                    someField: true,
                                    someField2: 'testA'

  • @lavolp3
    here is a short video of what is done at the moment.

    So what I have:

    1. Webserver which is based on the asws webserver. Updated version for MagicMirror is here. Changes made to cmd/asws.go file only.
      Download git

    2. build docker container from it (go to asws directory and run “ docker build -t asws_new .

    3. Clone to home/pi/www sample web-interface for MagicMirror clock module settings. It is bases on free SB Admin 2 bootstrap template.
      Git includes js/settings.js which is necessary for make everything works. Git is here:

    4. Run with a folloing command a docker container build in point 2 above: sudo docker run -d --restart unless-stopped -e DEBUG=true -p 80:80 -v $(pwd)/www:/www asws_new

    Sample config.js from video is located at www/config.js

  • @Serge @Sean @lavolp3 cool

    I found this the other day, maybe it will help your UI

    allows live dynamically positioning module content
