I am currently making a discord bot with the discord.js module and I want to integrate the firebase realtime database.
Here are all the code files realted.
These are two classes used to store data.
class User
{
constructor(userId, guildId)
{
this.userId = userId
this.guildId = guildId
this.blacklisted = false
this.muted = false
this.coins = 0
this.bank = 0
this.level = 0
this.xp = 0
this.xpTotal = 0
}
}
module.exports = User
class Guild
{
constructor(id)
{
this.id = id
this.welcomeEnabled = false
this.welcomeChannelId = ""
this.welcomeMessage = "Welcome to ${guildName} ${username}, we are now ${members} on the server."
this.goodbyMessage = "Goodby ${username}, we are now ${members} on the server."
this.helpEnabled = true
this.administrationEnabled = false
this.administrationPrefix = "!"
this.administrationRoleId = ""
this.administrationTicketCategoryId = ""
this.adminitrationAdminRoleId = ""
this.levelingEnabled = false
this.levelingChannelId = ""
this.levelingMessage = "${member}, you gained a level, you are now level : ${level} !"
this.levelingMultiplier = 1
this.economyEnabled = false
this.memberCountEnabled = false
this.memberCountChannelId = ""
}
}
module.exports = Guild;
And these are the two main files : firebase.js and sendData.js
const admin = require('firebase-admin');
var serviceAccount = require("./admin.json");
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "https://DATABASE_URL.DATABASE_REGION.firebasedatabase.app/"
});
const database = admin.database();
database.goOnline()
module.exports = database
const database = require('../firebase.js')
const User = require('../data/user.js')
module.exports = async (Discord, client, message) => {
const guildID = message.guild.id;
const userID = message.author.id;
if (userID === client.user.id) return;
let profileData = null
await database.ref(`/Users/${userID}-${guildID}`).on('value', (snapshot) => {
if (snapshot.val() == null) profileData = new User(userID, guildID)
else profileData = snapshot.val()
})
let guildData = null
await database.ref(`/Guilds/${guildID}`).on('value', (snapshot) => {
guildData = snapshot.val()
})
await database.ref(`/Users/${userID}-${guildID}`).set(profileData)
await database.ref(`/Guilds/${guildID}`).set(guildData)
}
I am using replit.com to host my files and code. My repl uses node version 12.16.1. One of the main problem is that I can see the data in the database but it is then being removed because the code in sendData.js cannot find it and resets it.
Does anyone know how I can fix this issue ?
CodePudding user response:
The Firebase Reference.on()
method does not return a Promise
. Thus, the code quickly returns and sets your refs to null
, deleting your data.
Instead, you may want to use Reference.once()
, which does return a Promise
:
const database = require("../firebase.js"),
User = require("../data/user.js");
module.exports = async (Discord, client, message) => {
const guildID = message.guild.id,
userID = message.author.id;
if (userID === client.user.id) return;
let profileData = null;
await database.ref(`/Users/${userID}-${guildID}`).once("value").then((snapshot) => {
if (snapshot.val() == null) profileData = new User(userID, guildID);
else profileData = snapshot.val();
});
let guildData = null;
await database.ref(`/Guilds/${guildID}`).once("value").then((snapshot) => {
guildData = snapshot.val();
});
await database.ref(`/Users/${userID}-${guildID}`).set(profileData);
await database.ref(`/Guilds/${guildID}`).set(guildData);
}
