code-tower-defense

Tower defense for developers. Towers are services, waves are traffic, creeps are requests, bosses are outages.

Usage

const { Game, TOWER_TYPES, CREEP_TYPES } = require('./src/game');

const game = new Game('Production Defense');

// Place towers
game.placeTower(TOWER_TYPES.CACHE, 0, 0);
game.placeTower(TOWER_TYPES.WAF, 2, 0);
game.placeTower(TOWER_TYPES.CDN, 4, 0);

// Start wave
game.startWave();

// Run simulation
for (let i = 0; i < 200 && !game.gameOver; i++) game.tick();

// Upgrade towers
game.upgradeTower(0);

console.log(game.mapView());
console.log(game.report());

Towers

• Cache ($50) — Slows requests, fast fire, low damage
• CDN ($70) — Long range, splash damage to multiple creeps
• WAF ($80) — Blocks malicious requests, high damage
• Rate Limiter ($40) — Fires very fast, slows everything
• Auth ($100) — Instant kills unauthenticated requests
• Logging ($30) — Reveals stealth creeps, no damage

Creeps

• GET Request (HP 30) — Basic, weak, plentiful
• POST Request (HP 60) — Heavier, more damage
• Bot Crawler (HP 45) — Fast scraper
• Aggressive Scraper (HP 80) — Ignores rate limits
• DDoS Zombie (HP 50) — Fast, in massive numbers
• Stealth Probe (HP 40) — Invisible without logging tower
• API Abuser Boss (HP 500) — The final boss
