Uncaught ReferenceError: require is not defined at config.js:15

@acimail01 Ok, I just got an idea.

Place your json somewhere in the config folder and place the following function in your config.js.

function loadJSON(filePath) {
    if (typeof module !== "undefined") {
        return require(filePath);
    } else {
        try {
            return JSON.parse($.ajax({
                type: "GET",
                url: filePath,
                async: false
            }).responseText);
        } catch (e) {
            console.error(e);
            return {};
        }
    }
}

And call it like:

modules: [
	loadJSON("config/clock.json")
]

This function will synchronisly load the given JSON, serializes it and returns it. This code is completly untestet, but it should work anyway:)

Edit: I just updated my answer to also work with node.js

thank you but wont work also.
Error:
ReferenceError: $ is not defined at loadJSON

I want to have all API keys and passwords from a common location and not scattered in the config.js, Hence the thought with a (yml) file.
maybe this can be solved via an array variable in the config.js or similar.

@acimail01 Ok, we can fix the $ is not defined at loadJSON.

Replace the function with the following which uses good old XMLHttpRequest:

fuction loadJSON(filePath) {
    if (typeof module !== "undefined") {
        return require(filePath);
    } else {
        try {
            var xmlhttp = new XMLHttpRequest();
            xmlhttp.open("GET", filePath, false);
            xmlhttp.send();
            if (xmlhttp.status === 200) {
                return JSON.parse(xmlhttp.responseText);
            } else {
                throw "Unexpected status code!";
            }
        } catch (e) {
            console.error(e);
            return {};
        }
    }
}

Did you manage to make this work? I’m trying to do kinda the same.

Thanks
