node.js - How to make and reference a configuration file in javascript

Question

I have a file that I am trying to make a config.json file for to be able to input and change the data quick and easily. The code below is my mention.js file that I mapped and referenced into my index.js File. The data below needs to be changed periodically and and a config file that I can set the 1. accountName and 2. userId Into my mention.js file. I’m new to npm and JavaScript and am still learning so any help and advice would be extremely helpful. Thank you!!

const map = new Map();
map.set("Pogo0303PTA",'<@679533427925450852>');
map.set("Wretched0671pta", "<@679533427925450852>");
map.set("Pogo0347PTA", "<@679533427925450852>");
map.set("Wretched0047pta", "<@679533427925450852>");
map.set("PogoDroid","<@679533427925450852>");
module.exports = map;```
    
     ```{
"acct1": "pogopta000",
"userid1": "65465132168451324"
},
{
"acct2": {account}
"userid2": {userID}
} ETC...

If you only need to read the config.json file once, you can use const config = require('./config.json'), assuming you have the .js file in the same folder as config.json.

If you need to read config.json you can use node's built in module fs by putting const fs = require('fs') at the top of your program and using let config = JSON.parse(fs.readFileSync('./config.json')) to read the file, and using fs.writeFileSync('./config.json', JSON.stringify(config)) to write the file.

You can structure your json file like:

   [
       {
            "accountName": "Pogo0303PTA",
            "userId": "<@679533427925450852>"
        },
        {
            "accountName": "Wretched0671pta",
            "userId": "<@679533427925450852>"
        },
        etc...
    ]

Hope this helped!
