Anime Design Pattern

Ready to supercharge your TypeScript with six battle-tested design patterns—shōnen-style? Whether you're commanding a pirate crew or mastering ninja techniques, these patterns will make your code as legendary as your favorite anime heroes. Let's dive into production-ready examples that actually work in the real world! 1. Singleton – Only One Captain per Crew Every pirate crew needs exactly one captain. Our hardened Singleton ensures you can appoint the captain only once—and locks down the instance to prevent tampering. class PirateCrew { // Holds our single crew instance private static instance: PirateCrew; // Tracks who's captain (null until first assignment) private captain: string | null = null; // Private so nobody can do `new PirateCrew()` outside private constructor() { // Lock down the instance: no one can add/remove properties later Object.freeze(this); } // Lazy-init access point: first call creates, subsequent calls return same public static getInstance(): PirateCrew { if (!PirateCrew.instance) { PirateCrew.instance = new PirateCrew(); } return PirateCrew.instance; } // Assigns our one-and-only captain; warns if you try again public assignCaptain(name: string): void { if (this.captain === null) { this.captain = name; console.log(`

Ready to supercharge your TypeScript with six battle-tested design patterns—shōnen-style? Whether you're commanding a pirate crew or mastering ninja techniques, these patterns will make your code as legendary as your favorite anime heroes. Let's dive into production-ready examples that actually work in the real world!

1. Singleton – Only One Captain per Crew

Every pirate crew needs exactly one captain. Our hardened Singleton ensures you can appoint the captain only once—and locks down the instance to prevent tampering.

class PirateCrew {
  // Holds our single crew instance
  private static instance: PirateCrew;

  // Tracks who's captain (null until first assignment)
  private captain: string | null = null;

  // Private so nobody can do `new PirateCrew()` outside
  private constructor() {
    // Lock down the instance: no one can add/remove properties later
    Object.freeze(this);
  }

  // Lazy-init access point: first call creates, subsequent calls return same
  public static getInstance(): PirateCrew {
    if (!PirateCrew.instance) {
      PirateCrew.instance = new PirateCrew();
    }
    return PirateCrew.instance;
  }

  // Assigns our one-and-only captain; warns if you try again
  public assignCaptain(name: string): void {
    if (this.captain === null) {
      this.captain = name;
      console.log(`
