sendNotification from external process...

[desq42]

Hi,

I´m fairly new to the whole node/socket thingy, but I´m wondering if it´s possible to send
a notification from an external process outside the MagicMirror Universe.
Specifically I would like to send a Notification from MotionEye, which has the ability to call a URL if it detects a Movement. This notification could perhaps show a picture of your frontdoor etc...
Perhaps somebody can give me a hint, if somethings like this would be possible, so I can dive into it.

Thank you.

You would probably use the NodeHelper to expose a URL, which MotionEye calls as a WebHook, triggering the notification. I'm not the utmost expert on this, but this should be the correct solution.

[desq42]

I got the same idea. A node_helper is already working... I´ll keep you posted.

One simple solution could be:

(in your node helper)

    start: function() {
        var self = this;
        this.expressApp.get(this.name + '/foo', function (req, res) {
            res.send('OK');
            self.doSomething();
        });
    },
    doSomething: function() {
        // Do something here, like sending a socket message to the frontend.
    }

You could now invoke the doSomething() method by calling: http://localhost:8080/modulename/foo.

(Code is not tested, but something like the above should work ...)

start: function() {
    var self = this;
    this.expressApp.get(this.name + '/foo', function (req, res) {
        res.send('OK');
        self.doSomething();
    }
},
doSomething: function() {
    // Do something here, like sending a socket message to the frontend.
}

Thanks for the Code-Snippet. Missing ")" bracket after ´/foo´?
I´m getting a "Cannot GET /urlserver/foo", if I´m calling the URL.

[MichMich]

Sorry, missing ); below the self.doSomething(). Fixed it in my example.

[desq42]

Thanks. I´m still getting a "Cannot GET /urlserver/foo" from my browser when I´m calling the url.
No "doSomething()" invoked.

[MichMich]

What is the exact url you are calling?

[desq42]

I´m running the whole thing on my mac. so : http://localhost:8080/urlserver/foo

[MichMich]

and urlserver is the exact name of your module?

[desq42]

correct.

[MichMich]

Should work. You could try debugging by checking all registered routes, using something like:

console.log(this.expressApp.stack);

(Not sure of that works ...)

[desq42]

okay. now it works. here is my node_helper code. - the problem was a missing "slash" in the path;
(BTW How do I tag my code correctly for viewing?

(the insert code tag doesn´t work for me)

`
var NodeHelper = require("node_helper");
var express = require('express');
var app = express();

module.exports = NodeHelper.create({
start: function () {
var self = this;
this.expressApp.get('/' + this.name + '/foo', function (req, res) {
res.send('Welcome');
self.doSomething();
});
},
doSomething: function() {
console.log("Called!");
this.sendSocketNotification('URLSERVER'," called!");
}
});
`

[MichMich]

use:

    ```javascript
    // your code here
    ```

Would it be ok for you to proceed any further discussion of this issue on: https://forum.magicmirror.builders? This way I can limit the use of GitHub issues to bug reports.

[desq42]

Of course. Thanks for your assistance.

Hello @desq42 , I want add face recognition based-on this model from external process and then send notification to MagicMirror. Could you share your program code as you discussed above?

Thank you :)
