      @AxLed MMM-ImagesPhotos uses it…

      the Module wants to use request, so issues a request to a local server (express path)
      which invokes the routine to get the list of photos//

      (instead of doing the sendSocketNotification to the node_module…)

      the express routine is like a cgi pgm invocation…

      from
      https://expressjs.com/en/guide/routing.html

      Route parameters

      the path can autoparse the url
      Route path: /users/:userId/books/:bookId
      Request URL: http://localhost:3000/users/34/books/8989
      req.params: { “userId”: “34”, “bookId”: “8989” }

      but the result, net, is the parms are in the req (uest) parameter object when the routine is called

            @AxLed so, it should be as simple as

            const express = require('express')
            
            // setup server path handler, for http get request
            this.expressApp.get("/MMM-Navigate",(req,res) =>{this.someFunction(req,res)});
            
            // handler dump request object
            someFunction: function(request,response){
                 console.log("request data="+JSON.stringify(request))
                response.send("Hello from MMM-Navigate");
            }

              Here is another example of express;

              const express = require('express')
              const bodyParser = require('body-parser')
              
              // in your member function of node_helper.js, usually it will be `.start()`
              
              this.expressApp.use(bodyParser.json())
              this.expressApp.use(bodyParser.urlencoded({extended: true}))
              var process = (req, res) => {
                var subpath = req.params.subpath
                if (CHECK_SOME_CONDITION) {
                  var requestObj = {
                    path: subpath,
                    query: req.query,
                    post: req.body,
                    method: req.method,
                  }
                  this.sendSocketNotification("REQUEST_COMING", requestObj)
                  res.status(200).send({status: 200})
                } else {
                  res.status(400).send({status: 400})
                }
              }
              
              this.expressApp.get("/YOUR_PATH/:subpath", process)
              this.expressApp.post("/YOUR_PATH/:subpath", process) // when you need POST method.

                Thanks for your quick response, you are faster than my programming timeslots in my “mancave” are. Today i had some time and got it working.

                I will test my module changes (for MMM-Navigate) on my mirror for some days, maybe i find some errors and can fix them before i upload it to quick to github in a poor “quality”.

                My intension was to get rid of MMM-Remote-Control in my installation, as i found errors (while a new install of my MM) and as it seems that MMM-Remote-Control is not maintainanced anymore.

                I added following features to MMM-Navigate:

                • Raspberry operations: any Shellcommands, i use it for
                  • restart of MM (pm2 restart mm)
                  • restart of Raspberry (sudo shutdown -h now)
                  • reboot of Raspberry (sudo reboot)
                • controlling MM by URL Calls (if you dont have a rotary encoder connected or while programming)

                stay healthy

                Regards
