    @newbi well, compliments does fetch, helloworld is a simple module

    my sample module is full function, but you wont need a node_helper as fetch works browser

    https://github.com/sdetweil/SampleModule

    cheerio is a nodejs lib you can find in npmjs , and will require the node_helper, so best to combine fetch and cheerio there

    the module development doc is here

        As i am working on my Windows Laptop, having a MagicMirror on a Raspy 3, can i develope on my Laptop or do i need to create a developement environment on my raspy (or on my Windows Laptop)?

          @newbi
          If you want to display how crowded yor gym is, use HTML Snippet or SmartWebDisplay. Cheerio is more for static pages useful. If yor gym does not block iframes thi is the easiest way imho.

          Regards, Chris.

            @newbi MagicMirror runs on windows

            need to follow the install instructions

            need nodejs (20.18.1, or 22 up)
            git

            there is a separate start script for windows

            npm run start:windows

              @newbi asked

              can i develope on my Laptop or do i need to create a developement environment on my raspy

              Dear @newbi ,
              neither, nor :-)
              You can “develop” physically on your laptop but the files (should) remain on the Raspi.
              On the Raspi therefore you do not need a “development” environment.
              You need a FTP Browser - connect this one via SFTP to the Raspi (SSH should be enabled on the Raspi - then SFTP works inherently).

              Than you click right on the remote (Raspi) File(s) you need to modify and open the file(s) with a (Laptop) local editor of your choice.
              When changes are done, save the file and restart the mirror - then you see the changes.

              At least this is the way as I do those things - currently NOT programming but changing custom.css and config.js.

              I am on a Windows laptop in most cases and I use BitVize for FTP and SSH and Sublime as Editor (which is for “programmers” because several “languages” are marked up nicely).
              For a quick view on the result I use VNC-Viewer which gives me a better view because I have my display in portrait format which isn’t displayed nicely in Webbrowser).

              HTH
              Regards,
              Ralf

                @chrisfr1976 thanks for giving me the two modules :)
                The first one seems to be promising. But I struggle to get the page been shown.
                Is it possible to show a page?
                And is it possible just to show the content of

                with a class name thats locatet somehere on the page?
                If not, i will stopp my effords and enjoy what i got so far, but it would be nice to get this information on the screen.

                @rkorell, well newbi to programming or confuguring a mirror. Not now to programming at all, but i do it in a completele different environment (more old school).
                I do nothing with webpages, nopthing with javascript, no libraries.
                My Configuration does work well, i do it wie ssh. not the best way, but the result is good.

                  @newbi if you use the iframe approach it is complete page only

                  thst didnt sound like what you wanted. as mentioned if you install one of the windows tools, you will get ssh window to pi, AND a windows file manager that adds drag/drop and double click to edit

                  i use notepad++ on windows as my editor, or sometimes visual studio

                  you can slso use a browser on windows to view the page, and debug the browser side of the module

                      no, an iframe is not exactly waht i wanted, but better than nothing. I struggle a bit to get the iframe to the correct position. Well if i can manage to scroll to the desired position, it would be helpfull, but i did not made it.
                      @sdetweil , i will chekc the module thanks. It is so much to find out, to test, a big cosmos on its own :)
