Async export of redis client in nodejs

The following code constructs a redis client and exports. I am fetching the redis password from vault secret management service and that call is a promise/async. The code doesnt wait for that call and it exports the redis client before async call completes. I am not sure what I am doing wrong here. Any idea?
import redis from 'redis';
import bluebird from 'bluebird';
import logger from '../logger';
import srvconf from '../srvconf';
import { getVaultSecret } from '../services/vault.service';
const vaultConfig = srvconf.get('vault');
bluebird.promisifyAll(redis);
let redisUrl = '';
const maskRedisUrl = (url) => url.replace(/password=.*/, 'password=*****');
const setRedisUrl = (host, port, pw) => {
const pwstring = pw ? `?password=${pw}` : '';
const url = `redis://${host}:${port}${pwstring}`;
console.log(`Setting redis_url to '${maskRedisUrl(url)}'`);
return url;
}
if (vaultConfig.use_vault) {
(async () => {
const secret = await getVaultSecret(`${vaultConfig.redis.secrets_path + vaultConfig.redis.key}`)
redisUrl = setRedisUrl(srvconf.get('redis_host'), srvconf.get('redis_port'), secret.PASSWORD);
})().catch(err => console.log(err));
} else {
if (!srvconf.get('redis_url')) {
redisUrl = setRedisUrl(srvconf.get('redis_host'), srvconf.get('redis_port'), srvconf.get('redis_password'));;
} else {
redisUrl = srvconf.get('redis_url');
console.log(`Found redis_url ${maskRedisUrl(redisUrl)}`);
}
}
const options = redisUrl
? { url: redisUrl }
: {};
const redisClient = redis.createClient(options);
redisClient.on('error', err => {
logger.error(err);
});
export default redisClient;

The problem is that (async () => {...})() returns a Promise and you are not awaiting it at the top-level, so the script continues to run past that line, sets options = {} and returns the redisClient.
What you need is a top-level await which is enabled by default in Node versions >= 14.8.0. However, if your project uses a version older than that, there is a workaround as shown below.
Please note that the below code is NOT tested since I do not have the same project setup locally.
Module
import redis from "redis";
import bluebird from "bluebird";
import logger from "../logger";
import srvconf from "../srvconf";
import { getVaultSecret } from "../services/vault.service";
const vaultConfig = srvconf.get("vault");
bluebird.promisifyAll(redis);
let redisUrl = "";
let redisClient = null;
const initRedisClient = () => {
const options = redisUrl ? { url: redisUrl } : {};
redisClient = redis.createClient(options);
redisClient.on("error", (err) => {
logger.error(err);
});
};
const maskRedisUrl = (url) => url.replace(/password=.*/, "password=*****");
const setRedisUrl = (host, port, pw) => {
const pwstring = pw ? `?password=${pw}` : "";
const url = `redis://${host}:${port}${pwstring}`;
console.log(`Setting redis_url to '${maskRedisUrl(url)}'`);
return url;
};
(async () => {
if (vaultConfig.use_vault) {
try {
const secret = await getVaultSecret(
`${vaultConfig.redis.secrets_path + vaultConfig.redis.key}`
);
redisUrl = setRedisUrl(
srvconf.get("redis_host"),
srvconf.get("redis_port"),
secret.PASSWORD
);
} catch (err) {
console.log(err);
}
} else {
if (!srvconf.get("redis_url")) {
redisUrl = setRedisUrl(
srvconf.get("redis_host"),
srvconf.get("redis_port"),
srvconf.get("redis_password")
);
} else {
redisUrl = srvconf.get("redis_url");
console.log(`Found redis_url ${maskRedisUrl(redisUrl)}`);
}
}
// Initialize Redis client after vault secrets are loaded
initRedisClient();
})();
export default redisClient;
Usage
At all places where you import and use the client, you always need to check if it is actually initialized successfully, and throw (and catch) a well defined error if it is not.
const redisClient = require("path/to/module");
...
if (redisClient) {
// Use it
} else {
throw new RedisClientNotInitializedError();
}

why does my discord bot don't seem to hear?

Well, I would create a discord bot that will stock given data in a database, .then I began to learn js
Until now i haven't any problem and found a lot of help in the web, before to create the database i tried to show detected data on the console but now I'm blocked and can't understand by myself where is the problem.
here is my code
const Discord = require('discord.js')
const client = new Discord.Client();
const { promisify } = require('util')
const sleep = promisify(setTimeout)
require('dotenv').config();
const BOT_TOKEN = '******'
client.on('ready', async () => {
console.log(`The bot is now working !\n\n`);
});
client.on('message', async (receivedMessage) => {
// Prevent bot from responding to its own messages
if (receivedMessage.author == client.user) {
return;
}
const { author, content, channel } = receivedMessage;
const { id } = author;
const trimmedContent = content.trim();
if (trimmedContent.startsWith('!ins')) {
console.log('Inside ins');
module.exports = {
prefix: "!ins",
fn: (msg) => {
let application = {}
let filter = (msg) => !msg.author.bot;
let options = {
max: 1,
time: 15000
};
msg.member.send("nom ?")
.then(dm => {
// After each question, we'll setup a collector on the DM channel
return dm.channel.awaitMessages(filter, options)
})
.then(collected => {
// Convert the collection to an array & get the content from the first element
application.name = collected.array()[0].content;
// Ask the next question
return msg.member.send("Parfait, maintenant votre mail ?")
})
.then(dm => {
return dm.channel.awaitMessages(filter, options)
})
.then(collected => {
application.emailAddress = collected.array()[0].content;
return msg.member.send("Excellent. Enfin, quel est votre âge ?")
})
.then(dm => {
return dm.channel.awaitMessages(filter, options)
})
.then(collected => {
application.pitch = collected.array()[0].content;
console.log(application)
})
}
}
}
});
// client.login logs the bot in and sets it up for use. You'll enter your token here.
client.login(' ');
The problem is that bot doesn't react to !ins command and on the console I only have the console.log 2 and 3
if you need any more info, feel free to ask them and thanks for taken time

I do think that you should code your main structure like mine because yours is a bit messy.
const Discord = require('discord.js');
const client = new Discord.Client();
const BOT_TOKEN = '...';
client.on('ready', async () => {
console.log(`The bot is now working !\n\n`);
});
client.on('message', async (receivedMessage) => {
// Prevent bot from responding to its own messages
if (receivedMessage.author == client.user) {
return;
}
const { author, content, channel } = receivedMessage;
const { id } = author;
// Removes whitespace from both ends of a string, "I personally do like this"
const trimmedContent = content.trim();
if (trimmedContent.startsWith('!ins')) {
console.log('Inside ins');
}
});
client.login(BOT_TOKEN);
process.on('exit', () => {
client.destroy();
console.log(`The bot is now disconnected !\n\n`);
});

Auto send message discord.js

I have a selfbot project for Discord (I know it's against the ToS, but this is just an experiment I'm not going to use it)
I want the selfbot to send a message like "this is an example message" every hour in a specific channel with the ID (783651779207626752)
What and where should I add something in the code?
const Discord = require("discord.js")
const client = new Discord.Client()
const { prefix, token } = require("./config.json")
const fs = require("fs")
const { table, getBorderCharacters } = require("table")
const commands = new Discord.Collection();
let commandFiles
function loadCommands() {
console.log("loading commands..")
const startTime = new Date().getTime()
commandFiles = fs.readdirSync("./commands/").filter(file => file.endsWith(".js"));
const failedTable = []
if (commands.size > 0) {
for (command of commands.keyArray()) {
delete require.cache[require.resolve(`./commands/${command}.js`)]
}
commands.clear()
}
for (file of commandFiles) {
let command
try {
command = require(`./commands/${file}`);
let enabled = true;
if (!command.name || !command.description || !command.run) {
enabled = false;
}
if (enabled) {
commands.set(command.name, command);
} else {
failedTable.push([file, "❌"])
}
} catch (e) {
failedTable.push([file, "❌"])
}
}
}
loadCommands()
exports.reloadCommands = loadCommands
client.once("ready", () => {
console.log("logged in as " + client.user.username + "#" + client.user.discriminator)
})
function runCommand(cmd, message, args) {
args.shift()
try {
commands.get(cmd).run(message, args)
} catch(e) {
console.log(e)
}
}
setTimeout(() => {
client.login(token)
}, 1500)

You can make another file called globalFunctions.js
Add anything that you want to be running globally as an IFFE
This will insure that every IFFE has its own block of code
globalFunctions.js
export default globalFunctions(client, channel){
/*
IFFE
*/
(function(){
setInterval(()=>{
channel.send('some message')
}, /*Time you want*/)
})()
// and so on
}
OR "I recommend this if you want to scale"
you can add other files for each global function and add then to global function file
/*Import other functions*/
import periodicMessage from 'PATH'
export default globalFunctions(client, channel){
periodicMessage(client, channel);
}
and just import this function to the main file and run it after the server runs
main.js
import globalFunctions from 'PATH'
client.once('ready', () => {
// Your code
globalFunctions(client, channel)
})

Discord.js Join and Leave Events not working

i am trying to make a bot with some new tricks i figured out but the events arent working.
When someone Joins or Leaves, it doesn't event log it in the console.
index.js:
const config = require('./config.js');
const {Client} = require('discord.js');
const client = new Client();
const utils = require('./utils.js');
let prefix = config.prefix;
client.on('ready', () => {
utils.ready(client);
utils.registerEvents(client);
});
client.on("message", message => {
utils.onMessage(client, message, prefix);
})
client.login(config.token);
utils.js:
const fs = require("fs");
const eventHandler = require('./eventHandler.js');
module.exports.ready = async (client) => {
console.log("--------------------");
console.log("Name: " + client.user.username);
console.log("ID: " + client.user.id)
console.log("--------------------");
client.user.setActivity("Team INSTINCT BETA", {"type": "STREAMING", "url": "https://twitch.tv/hanyaku"});
}
module.exports.onMessage = async (client, message, prefix) => {
let raw = message.content.slice(prefix.length).split(" ");
let cmd = raw[0];
let rawArgs = raw.join(" ");
let args = rawArgs.slice(cmd.length).split(" ");
if(message.content.startsWith(prefix))
{
fs.exists(`./commands/${cmd}.js`,function(exists){
let cmdFile = require(`./commands/${cmd}.js`);
cmdFile.run(client, message, args);
});
}
}
module.exports.registerEvents = async (client) => {
eventHandler.register(client,'guildMemberAdd');
eventHandler.register(client,'guildMemberRemove');
}
eventHandler.js:
module.exports.register = async (client, eventName) => {
eval(`${eventName}(client);`);
}
function guildMemberAdd(client)
{
client.on('guildMemberAdd', member => {
let eventFile = require(`./commands/guildMemberAdd.js`);
eventFile.run(client, member);
});
console.log("Event guildMemberAdd Registriert");
}
function guildMemberRemove(client)
{
client.on('guildMemberRemove', member => {
let eventFile = require(`./commands/guildMemberRemove.js`);
eventFile.run(client, member);
});
console.log("Event guildMemberRemove Registriert");
}
guildMemberAdd.js:
const { Client, Collection, MessageEmbed, MessageAttachment } = require('discord.js');
const fs = require("fs");
const Canvas = require('canvas');
const fetch = require("node-fetch");
module.exports.run = async (client, member) => {
console.log('Member Joined');
let channel = client.channels.cache.get('776942211798532106');
let { user } = member;
var name = user.tag;
let embed = new MessageEmbed()
.setTitle('Welcome')
.setDescription('Have a nice time, ' + name)
channel.send(embed);
}
I guess the error is in the eventHandler.js or in the guildMember.js
I hope to get help.
Greetings

I think you need to enable SERVER MEMBERS INTENT.
Go to discord dev portal and in bot section there will be SERVER MEMBERS INTENT option, enable it.

Chunks of code being ignored. No errors, no logs. Might be API related

The code below doesn't give any errors but I have a weird bug anyway. I have four streams to aggregate twitter feeds to a discord channel. 3 of those often work. but whenever I run the code there is always a feed not coming through, no line is getting executed in that stream. This often happens with the IntelFeed and/or covid-19feed. When I wait for some time or repeatedly rerun the code it starts working. I think it may be due to the structure of the code (not having enough time to fulfill the conditions) or due to the API. But I can't confirm the latter one.
