If you’re a Brawl Stars fan like me, you know how addictive it is to track your trophy count, brawler upgrades, and win rates. But opening the game every single time just to check stats? That can get tiring—especially if you want to monitor trends over time.
So I thought, why not build a bot that automatically fetches my Brawl Stars stats, analyzes them, and even gives me friendly reminders to upgrade my brawlers?
Using the Brawl Stars Official API, Node.js, and some clever data processing, we can create a bot that becomes your personal Brawl assistant.
What You’ll Need
Before we dive into the code, let’s get our checklist ready:
- A Brawl Stars Developer Account
- A Brawl Stars API Key (linked to your IP address)
- A working Node.js setup
- Basic knowledge of JavaScript, REST APIs, and JSON
- A text editor (I use VS Code)
- Your player tag from the game
Step 1: Get Your API Key
- Go to the Brawl Stars Developer Portal.
- Sign in with your Supercell ID.
- Create a new API key and whitelist your IP address.
- Copy the API key — we’ll store it securely in a .env file.
Step 2: Set Up Your Node.js Project
mkdir brawl-bot
cd brawl-bot
npm init -y
npm install axios express dotenv node-cron
Create a .env file:
BRAWL_API_KEY=your_api_key_here
PLAYER_TAG=#YOURTAG
Step 3: Create the Express Server & Fetch Stats
We’ll build a basic server to fetch and display your stats.
// server.js
require('dotenv').config();
const express = require('express');
const axios = require('axios');
const cron = require('node-cron');
const app = express();
const port = 3000;
const api = axios.create({
baseURL: 'https://api.brawlstars.com/v1',
headers: {
Authorization: `Bearer ${process.env.BRAWL_API_KEY}`,
},
});
// Helper to format tag
function formatTag(tag) {
return encodeURIComponent(tag.replace('#', ''));
}
// Fetch player stats
async function getPlayerStats() {
const tag = formatTag(process.env.PLAYER_TAG);
const res = await api.get(`/players/${tag}`);
return res.data;
}
// Example cron job to fetch every hour
cron.schedule('0 * * * *', async () => {
const stats = await getPlayerStats();
console.log(`[BOT] ${stats.name} - ${stats.trophies} trophies`);
});
app.get('/', async (req, res) => {
const stats = await getPlayerStats();
res.json({
name: stats.name,
trophies: stats.trophies,
highestTrophies: stats.highestTrophies,
club: stats.club ? stats.club.name : 'No club',
});
});
app.listen(port, () => {
console.log(`🚀 Server running at http://localhost:${port}`);
});
Step 4: Analyze & Recommend Upgrades
We can enhance our Nulls Brawl APK bot by analyzing which brawler is closest to the next rank.
async function getBrawlers() {
const tag = formatTag(process.env.PLAYER_TAG);
const res = await api.get(`/players/${tag}/brawlers`);
return res.data.items;
}
async function recommendUpgrade() {
const brawlers = await getBrawlers();
const target = brawlers
.filter(b => b.power < 11)
.sort((a, b) => a.power - b.power)[0];
console.log(`💡 Tip: Upgrade ${target.name} to level ${target.power + 1} next!`);
}
recommendUpgrade();
Step 5: Automate & Notify
You can integrate with Discord, Telegram, or even email to send automatic updates.
Example with Discord Webhook:
const webhookUrl = 'YOUR_DISCORD_WEBHOOK_URL';
async function sendDiscordMessage(content) {
await axios.post(webhookUrl, { content });
}
cron.schedule('0 20 * * *', async () => {
const stats = await getPlayerStats();
await sendDiscordMessage(`📊 ${stats.name} now has ${stats.trophies} trophies! Keep pushing!`);
});
Step 6: Handle Rate Limits & Retries
Brawl Stars API enforces strict rate limits. Read the x-ratelimit-remaining and x-ratelimit-reset headers and back off when you’re close to the cap. Implement exponential backoff to avoid bursts.
async function safeGet(url, tries = 3) {
try {
const res = await api.get(url);
return res.data;
} catch (e) {
const retryAfter = Number(e.response?.headers?.['x-ratelimit-reset'] || 1);
if (tries > 0 && e.response?.status === 429) {
await new Promise(r => setTimeout(r, retryAfter * 1000));
return safeGet(url, tries - 1);
}
throw e;
}
}
Step 7: Cache for Speed (and Kindness)
Cache player/brawler responses for 1–5 minutes in memory (or Redis) to reduce API calls and improve response times.
const cache = new Map();
function memo(key, ttlMs, getter) {
const hit = cache.get(key);
if (hit && (Date.now() - hit.t) < ttlMs) return hit.v;
return getter().then(v => (cache.set(key, { v, t: Date.now() }), v));
}
Final Thoughts
This bot isn’t just a fun weekend project — it’s a tool that can help you track progress, improve your gameplay, and stay motivated.
You could take it further by:
- Tracking your battle log for win/loss streaks
- Building a web dashboard to visualize your stats
- Creating leaderboards for your club
- Adding AI-powered strategy tips based on performance
With the Brawl Stars API and a little creativity, your bot can become your ultimate gaming companion.
