Exporting function(s) does not make it available in other module

Question

I'm trying to use the retrieve_endpoints function in cli_config.js. I added the functions to the module exports and added the require in the cli_config file. Why can't I seem to call the retrieve_endpoints function?

collector.js

async function retrieve_endpoints(enviromnent) {
    let configured_endpoints = []; 

    return configured_endpoints;
}



module.exports = ({ server }) => {
    return {
        retrieve_endpoints
    };
}

cli_config.js

const collector = require('../collector/collector');



function webapi_source({ menus }) {
    endpoints = await collector.retrieve_endpoints(env);
            
}

Answer 1

The main problem with your example is that you replace the exports object with a function that returns an object in collector.js, but in cli_config.js you don't call that function, you expect a bare object. Based on your example I think you don't need that function in the first place. Sulman is also right that there is a syntax error around async / await, and a few others, but I think those problems are probably just a copy-paste error.

Using ECMA modules

It's 2024, I suggest you rather to write Standard ECMAScript Modules. All you have to do is to rename your files to .mjs, this will allow you to use the export / import syntax.

collector.mjs

export async function retrieve_endpoints(enviromnent) {
    let configured_endpoints = []; 

    return configured_endpoints;
}

cli_config.mjs

import { retrieve_endpoints } from '../collector/collector.mjs';

async function webapi_source({ menus }) {
    endpoints = await retrieve_endpoints(env);
}

Using CommonJS

If you have to use CommonJS Modules, then the fix would look something like this:

collector.js

async function retrieve_endpoints(enviromnent) {
    let configured_endpoints = []; 

    return configured_endpoints;
}

module.exports.retrieve_endpoints = retrieve_endpoints;

cli_config.js

const collector = require('../collector/collector');

async function webapi_source({ menus }) {
    endpoints = await collector.retrieve_endpoints(env);
}

Answer 2

The issue in your webapi_source function is that you are trying to use the await keyword without marking the function as async.

async function webapi_source({ menus }) {
    endpoints = await collector.retrieve_endpoints(env);
}
