Dumpus is a cross-platform app that allows users to view statistics collected by Discord using their Discord Data Package.

This project is the follow-up of DDPE made by Androz2091. It takes all its ideas and dives deeper.

My role as a frontend freelancer was to create full mockups of the app, implement them and make sure the app is adapted to all platforms (web, mobile and desktop). I had to interact with the Python API made by Androz2091 and keep all logic client-side for security reasons.

To achieve this goal I used the following technologies:

Purpose and Goal

This project is done for my friend and client Androz2091. We have already worked together in the past so collaboration is really made easy.

This project has several goals:

  • Make a better version than DDPE
  • Make it cross-platform (big challenge!)
  • Design the whole app
  • Keep it open-source and maitain it
  • Keep logic client-side
  • Working i18n

A lot of challenges to overcome, but what an enriching experience!

Spotlight: cross-platform

This project has so many interesting aspects but let’s focus on getting the app cross-platform.

I first started to develop the app on the web using Next.js, making sure it’s client-side only by using static exports. Mobile and desktop indeed don’t support SSR so this had to be taken into account from the beggining.

Running the app on desktop

After getting a POC working on web, getting it running on desktop was…effortless. Really, it only required to follow the Tauri documentation and that’s pretty much it!

Running the app on mobile

Setting up Capacitor was a different kettle of fish. We first had to figure out how to handle HMR in development while keeping a clean config for production. We ended up with the fairly minimal one:

// https://github.com/dumpus-app/dumpus-app/blob/main/capacitor.config.ts
import { CapacitorConfig } from '@capacitor/cli'
import os, { NetworkInterfaceInfo } from 'node:os'

function localIpAddress() {
    const interfaces = Object.values(os.networkInterfaces()).filter(
        (iface) => iface !== undefined
    ) as NetworkInterfaceInfo[][]
    const aliases = interfaces
        .filter((iface) =>
            iface.some((alias) => alias.family === 'IPv4' && !alias.internal)
        .map((iface) => {
            iface = iface.filter(
                (alias) => alias.family === 'IPv4' && !alias.internal
            return iface
    const ipAddress = aliases.find(
        (alias) => !alias.address.startsWith('172')

    if (!ipAddress) {
        throw new Error('No suitable network interface found.')

    return ipAddress

const isDev = process.env.NODE_ENV === 'development' || false
if (isDev) {

export default {
    appId: 'app.dumpus.app',
    appName: 'Dumpus',
        ? {
              server: {
                  url: `http://${localIpAddress()}:3000`,
                  cleartext: true,
        : {
              webDir: 'dist',
} satisfies CapacitorConfig

However, some complexity is moved to our package.json because of the many environments. Here is an extract:

    "scripts": {
        "android:dev": "cross-env-shell NODE_ENV=development \"echo 'Run `pnpm dev:mobile` in parallel' && cap sync && cap run android\"",
        "android:dev:static": "cross-env-shell NODE_ENV=production \"echo 'Run `pnpm build:mobile first` && cap sync && cap run android\"",
        "build": "cross-env-shell NEXT_PUBLIC_DEPLOY_ENV=web \"pnpm build:shared\"",
        "build:desktop": "cross-env-shell NEXT_PUBLIC_DEPLOY_ENV=desktop \"pnpm build:shared\"",
        "build:mobile": "cross-env-shell NEXT_PUBLIC_DEPLOY_ENV=mobile \"pnpm build:shared\"",
        "build:shared": "pnpm script:list-locales && next build",
        "dev": "cross-env-shell NEXT_PUBLIC_DEPLOY_ENV=web \"pnpm dev:shared\"",
        "dev:desktop": "cross-env-shell NEXT_PUBLIC_DEPLOY_ENV=desktop \"pnpm dev:shared\"",
        "dev:mobile": "cross-env-shell NEXT_PUBLIC_DEPLOY_ENV=mobile \"pnpm dev:shared\"",
        "dev:shared": "pnpm script:list-locales && next dev",
        "dev:tauri": "tauri dev",
        "ios:dev": "cross-env-shell NODE_ENV=development \"cap sync && cap run ios\"",
        "ios:dev:static": "cross-env-shell NODE_ENV=production \"cap sync && cap run ios\"",
        "prepare": "pnpm script:list-locales",
        "script:list-locales": "node ./scripts/list-locales.cjs",
        "start": "serve dist",
        "tauri:icon": "tauri icon ./ios/App/App/Assets.xcassets/AppIcon.appiconset/AppIcon-60@3x~car.png",
        "trapeze:run": "node ./trapeze.config.mjs"

Pretty massive as you can see. But I’m digress, the other hard part was getting the local server running once the app built. And the issues we faced were actually caused by Next 13.

If you don’t know about Next 13, it introduces the App directory which uses React Server Components (RSC). There are basically 2 ways of building Next apps and they can coexist (you can have both app and pages folders).

Well, it turns out we were using both for obscure reasons (because of some misunderstanding actually) and Capacitor was not able to handle it. Switching everything to the app dir solved all the issues I had for countless hours.

If you have other questions about getting Capacitor and Next.js running, DM me on Twitter and I’ll update this part!

Getting iOS to work

I’m an Android user but when it comes to cross-platform development, you have to test your app on real devices to make sure everything works. Therefore, I invested in a Mac Book Air and an iPhone SE to be able to debug and troubleshoot any issues. I couldn’t have completed the project without those.

Current status

Dumpus has been officially released and made open-source in August! People have alredy contributed and it’s now getting more and more users!

I’ll keep maintaining the repo for now if there are any critical issues, but feel free to contribute and help us!

Lessons Learned

I learned a few things in this project:

  • Cross-platform: this is something I had been eager to learn for a long time and that was the perfect time for it
  • Async state management: I’ve learned a lot about using React Query
  • Overestimate the time you need: you always need more time than expected. A few bugs remain, you’re waiting for other people’s work… Play it safe!

This app contains quite some logic and this led me to learn more about TDD and clean architecture. I can’t wait to apply those practises to real projects!
