fs.writeFile not writing to file unless run twice

I'm trying to learn Node.js so I've been trying to write a simple Discord bot. It runs fine except when I try to write to a config file. It only writes to the file when I run the command twice or if another command is run right after it. I can't seem to figure out why it does that. It succeeds in posting a message in Discord after every command, but it's just the file that doesn't get updated. It doesn't output an error to the console either.

I have the code below and the config.json sample. Any help would be greatly appreciated.

config.json:


"ownerID": "1234567890",
"token": "insert-bot-token-here",
"prefix": "!",
"defaultStatus": "status-here"



const Discord = require("discord.js");
const client = new Discord.Client();
const fs = require("fs")

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

client.on("ready", () =>
console.log("I am ready!");
client.user.setActivity(config.defaultStatus,
type: 'WATCHING'
);
);

client.on("message", (message) => );

client.login(config.token);

That works only the second time because you're declaring configData before you change the config object.

configData

config

configData = JSON.stringify(config, null, 2); //saves the config as a string
// you do all your stuff, including changing the prefix, for example
config.prefix = '-'; //this is stored in config, but not in configData
// then you write the file with the old data
fs.writeFile("./config.json", configData, (err) => console.error);


That causes the changes to be delayed every time.

You should create the configData after changing config:

configData

config

...
config.prefix = '-'; // inside the command
...
let configData = JSON.stringify(config, null, 2);
fs.writeFile('./config.json', configData, err => console.error);
