THANK YOU SO MUCH! I will probably be back with more questions, but not around this issue.

config.address===“0.0.0.0”?“localhost”:config.address

oops
need parens around that…

strange… I just found the following code at the top of my file. I did not add it there. Going to delete it now.

const config = require("../../config/config");

I added let header = “” and let cors_url = jdhflrkgd. I did not add anything else at all.

exact code below:

        let header = "";

        // this is the API call url
        let original_url = "http://api.seatgeek.com/2/events?lat=" + self.config.latitude + "&lon=" + self.config.longitude + "&per_page=" + self.config.eventCount + "&datetime_utc.gte=" + today + "&datetime_utc.lte=" + oneweek + "&range=" + self.config.range + "&type=concert" + "&client_id=" + self.config.clientID + "&client_secret=" + self.config.clientSecret;
        
        // this is the cors URL
        let cors_url = "http://" + config.address==="0.0.0.0"?"localhost":config.address + ":" + config.port + "/cors?" + header + "&url=" + original_url;
    
        // fetching the data from seatgeek
        fetch(cors_url)

config is already defined for you

this.config is the stuff from your module entry
config. is ALL the config.js

    ```

// this next block is to deal with a CORS permissions issue with the API
let header = “”;

    // this is the API call url
    let original_url = "http://api.seatgeek.com/2/events?lat=" + self.config.latitude + "&lon=" + self.config.longitude + "&per_page=" + self.config.eventCount + "&datetime_utc.gte=" + today + "&datetime_utc.lte=" + oneweek + "&range=" + self.config.range + "&type=concert" + "&client_id=" + self.config.clientID + "&client_secret=" + self.config.clientSecret;
    
    // this is the cors URL
    let cors_url = "http://" + config.address==="0.0.0.0"?"localhost":config.address + ":" + config.port + "/cors?" + header + "&url=" + original_url;

Is this right?

yes

almost …

"IP ADDRESS HERE"

MUST be

"0.0.0.0" 

(which is the MM value for listen on any network adapter)

let header = "",

let original_url = "https://api.seatgeek.com/2/events?client_id=MYCLIENTID&client_secret=MYCLIENTSECRET "

let cors_url = "http://" + config.address==="IP ADDRESS HERE"?"localhost":config.address + ":" + config.port + "/cors?" + header + "&url=" + original_url

and then I fetch(cors_url)?

Is this right?

you use that code to build your fetch url (and put it in the original_url variable)

I just created the JS code to do the build from the parts
the comment in the linked file just doesn’t help me at all…

and when you execute the fetch, it sends it to magic mirror code that forwards on supposedly to avoid the cors problem…

honestly the whole thing is a bit confusing to me. I’m not sure where it is supposed to go… as part of where I define the URL variable?

there used to be free services where you could send the request to them and they would forward (from a known address) and send the response back to you
a CORS proxy, most of those have gone away or are no longer free.

we’ve added a cors safe fetch (we think) to the MM system

see ~/MagicMirror/js/server_functions.js
( I have tried to break that into understandable reusable sections below )

u change your url request to this cors_url

let header_stuff_if_any="sendheaders=header1:value1,header2:value2&expectedheaders=header1,header2"
// empty string, "",  if no headers

let original_url="http://www.test.com/path?param1=value1"

-----------

let_cors_url=

"http://"+
// use the config.address value, unless its "0.0.0.0", then use "localhost"
config.address==="0.0.0.0"?"localhost":config.address
+
":"
+config.port+
"/cors?"+ 
header_stuff
+"&url="+
original_url 

and we will send it, and return the response to your fetch

postman didn’t use localhost it used the local IP address

you ‘might’ get to fix it in config.js ? maybe

from terminal window do

ip addr

that give u the local machine ip address
use that in the config.js

address:""

instead of locahost…

CORS basically means, “hey, you are not in our known approved access network, get lost”

I tested the exact link from the first error “Access to fetch at…” in postman and I get a clean response

npm init -y 
npm install luxon 

if u don’t do the npm init in your module folder the module will be installed in the root MM node_modules, then not found here

I am moving between my mac and raspberry pi

magicmirror will run on your mac…

use my install script

depending where your module is , the quick way

mv MMM-ConcertsAroundMe ~/MagicMirror/modules

First, I got the following message when trying to move it:

mv MMM-ConcertsAroundMe /modules
mv: cannot move 'MMM-ConcertsAroundMe' to '/modules': Permission denied

Will paste the console errors as well, I am moving between my mac and raspberry pi
