I want to take the message information from the user and save it in a JSON file and this data is constantly added, but with the following code, this data is constantly replaced. and I don't replace data I want to add data this is my code :
const fs = require("fs");
const { Client, Intents } = require("discord.js");
const client = new Client({
intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES],
});
const now = new Date();
const obj = {
table: [],
};
let confirm = false;
const { badWords } = require("../badWordList.json");
client.on("message", async (message) => {
if (message.author.bot) return;
for (let i = 0; i < badWords.length; i++) {
if (message.content.toLowerCase().includes(badWords[i].toLowerCase()))
confirm = true;
}
if (confirm) {
obj.table.push({
name: message.author.username,
date: `${now.getFullYear()}/${now.getMonth()}/${now.getDate()}`,
message: message.channel.messages.channel.lastMessage.cleanContent,
});
fs.writeFile("myjsonfile.json", JSON.stringify(obj), function (err) {
if (err) throw err;
console.log("complete");
});
}
});
When using the fs.writeFile() it replaces the content of the file, as written in the docs.
At a first glance, you might want to use fs.write(), see the docs for usage.
But the NodeJS docs says :
It is unsafe to use fs.write() multiple times on the same file without waiting for the callback. For this scenario, fs.createWriteStream() is recommended.
Since you are in asynchronous mode, you shoud probably define a write stream to the file and then write to it, it gives you something like that :
// -snip-
const whateverJsonFileStream = fs.createWriteStream("myjsonfile.json");
client.on("message", async (message) => {
//-snip-
if (confirm) {
obj.table.push({
name: message.author.username,
date: `${now.getFullYear()}/${now.getMonth()}/${now.getDate()}`,
message: message.channel.messages.channel.lastMessage.cleanContent,
});
whateverJsonFileStream.write(JSON.stringify(obj), function (err) {
if (err) throw err;
console.log("complete");
});
}
});
