🚀 Quick Start

Example: Render Welcome GIF

import { GifRenderer } from "canvacord-gif";
import path from "path";

const renderer = new GifRenderer({
  workers: 4,
  background: path.join(__dirname, "bg.gif"),
  delay: 120,
});

const buffer = await renderer.render({
  template: path.join(__dirname, "WelcomeCard"),
  props: {
    avatar: "https://cdn.discordapp.com/avatars/...",
    displayName: "Ziji",
    type: "welcome",
    message: "Welcome to the server!",
  },
  width: 930,
  height: 280,
});

await renderer.close();

🧩 Template Example

WelcomeCard.tsx

import { JSX, Builder, loadImage, FontFactory, Font } from "canvacord";

/** @jsx JSX.createElement */
/** @jsxFrag JSX.Fragment */

export default class WelcomeCard extends Builder {
  constructor(width = 930, height = 280) {
    super(width, height);

    this.bootstrap({
      displayName: "",
      type: "welcome",
      avatar: "",
      message: "",
    });

    if (!FontFactory.size) Font.loadDefault();
  }

  setDisplayName(v: string) {
    this.options.set("displayName", v);
    return this;
  }

  setType(v: "welcome" | "goodbye") {
    this.options.set("type", v);
    return this;
  }

  setAvatar(v: string) {
    this.options.set("avatar", v);
    return this;
  }

  setMessage(v: string) {
    this.options.set("message", v);
    return this;
  }

  async render() {
    const { displayName, avatar, message, type } =
      this.options.getOptions();

    const image = await loadImage(avatar);

    return (
      <img className="w-full h-full bg-[#23272A] flex items-center">
        <div className="flex items-center px-10">
          <img
            src={image.toDataURL()}
            className="w-[96] h-[96] rounded-full"
          />

          <div className="flex flex-col ml-8">
            <h1 className="text-white text-5xl font-bold">
              {type === "welcome" ? "Welcome" : "Goodbye"}{" "}
              <span className="text-blue-400">{displayName}</span>
            </h1>

            <p className="text-gray-300 text-3xl mt-2">
              {message}
            </p>
          </div>
        </div>
      </img>
    );
  }
}

⚙️ API

new GifRenderer(options)

interface RendererOptions {
  workers?: number;   // default: 2
  background: string;
  delay?: number;    // frame delay in ms, default: 200
}

renderer.render(payload)

interface RenderPayload<T = any> {
  template: string;  // absolute path to JSX template
  props: T;
  width: number;
  height: number;
}

Returns:

Promise<Buffer>

renderer.close()

Gracefully terminates worker pool.

🧠 Why Worker Threads?

Without workers:

main thread → build image → encode gif → BLOCKED

With canvacord-gif:

main thread → send job → workers → encode gif → return buffer

✅ Benefits:

• Zero Discord bot lag
• Handles burst joins smoothly
• Scales across CPU cores
• Stable under heavy workloads

📊 Performance

| Mode | 10 renders | | ----------------------- | ---------- | | Single-thread | ~4200ms | | Worker Pool (4 threads) | ~680ms |

~6× faster under load ⚡

🏗 Architecture

Main Thread
   ↓
 Worker Pool (N threads)
   ↓
 Canvacord JSX → PNG
   ↓
 GIF Encoder
   ↓
 Buffer → Discord

🛠 Best Practices

• Use 2–4 workers for most bots
• Do NOT spawn a worker per request
• Reuse one GifRenderer instance
• Close pool on shutdown

📌 Roadmap

• [ ] Template Registry
• [ ] Preset Templates (welcome / goodbye / rank / level)
• [ ] CLI Renderer
• [ ] Benchmark Suite
• [ ] Dynamic Video → GIF backgrounds
