Simple script for preparing "CHANNEL_ID/MESSAGE_ID" formatted file out of Discord package. Just for support removal purposes

prepare_messages.js

import { readdirSync, readFileSync, writeFileSync } from "fs"

const channelIds = (() => {
    const files = readdirSync("Messages", {  withFileTypes: true })
        .filter(x => x.isDirectory() && x.name.startsWith("c"))

    return files.map(x => x.name.slice(1))
})()

const messages = channelIds.reduce((acc, id) => {
    const str = readFileSync(`Messages/c${id}/messages.json`, "utf-8")
    const json = JSON.parse(str)

    acc[id] = json.map(({ ID }) => ID)

    return acc
}, {})

writeFileSync(
    "messages.txt",
    Object.entries(messages)
        .flatMap(([channelId, messageIds]) =>
            messageIds.map(messageId => `${channelId}/${messageId}`)
        )
        .join("\n")
)
