How to set custom path or package name to generated .data files in generated .js file?

[oregu1]

Could anyone explain how to set custom path inside of generated .js file to generated .data file?
There are variables generated by Emscripten itself in output .js file.

var PACKAGE_NAME = '2x.data';
var REMOTE_PACKAGE_BASE = '2x.data';

In my case this file is called 2x.js

is it possible to set in cmake or elsewhere custom name or path to .data file?

I want to make it like this:

var PACKAGE_NAME = '/static/game/2x.data';
var REMOTE_PACKAGE_BASE = '/static/game/2x.data';

The file packager should generate code that looks like this:

var REMOTE_PACKAGE_NAME = Module["locateFile"]?.(REMOTE_PACKAGE_BASE, "") ?? REMOTE_PACKAGE_BASE;

This means that if you specific a locateFile handling in your Module object you can do things line prepend /static/game/ at runtime.

My code looks this:

var REMOTE_PACKAGE_NAME = (_Module$locateFile = (_Module$locateFile2 = Module['locateFile']) === null || _Module$locateFile2 === void 0 ? void 0 : _Module$locateFile2.call(Module, REMOTE_PACKAGE_BASE, '')) !== null && _Module$locateFile !== void 0 ? _Module$locateFile : REMOTE_PACKAGE_BASE;

I can't figure out how to set proper path to my .data files.

I found the next solution but I don't like it at all. Invoke this inside my init.js file
Could you tell me or show reference how to make the same via emscripten?

var Module = {
    locateFile: function(path, prefix) {
        console.log('Emscripten looks for:', path);
        
        if (path.endsWith('.data')) {
            return '/static/game/' + path;
        }
        
        return prefix + path;
    }
};

You can use --pre-js=myfile.js and put that code in myfile.js.
