WOLFDEV — wolfdev-rn-sticker-api

A small, super-rad WebSocket sticker converter by WOLFDEV — converts images/videos to WebP stickers (exportable module or standalone WebSocket server).

Features

• Image -> WebP sticker (512x512, transparent background)
• Video -> animated WebP sticker (trim to max 10s)
• Programmatic module export + simple WebSocket server starter

Prerequisites

• Node.js >= 18
• ffmpeg installed and available in PATH (required by fluent-ffmpeg)
• On some systems sharp needs build deps — see sharp docs if install errors occur

Install npm install wolfdev-rn-sticker-api

Or for local development: npm install (then run server or test scripts in this repo)

Quick start (programmatic) import { createWebSocketServer } from 'wolfdev-rn-sticker-api';

const wss = createWebSocketServer({ port: 3000 }); // Clients connect to ws://host:3000 and send JSON: // { "type": "image" | "video", "buffer": <Array | base64-string> } // Server responds with { success: true, sticker: "" }

API

• createWebSocketServer(options = { port }) -> WebSocketServer
• createImageSticker(imageBuffer: Buffer) -> Promise
• createVideoSticker(videoBuffer: Buffer) -> Promise

Testing locally (repo)

1. Ensure sample.jpg and sample.mp4 are placed in src/
2. Start server: node src/server.js
3. Run test client: node src/test.js Output .webp files will be saved in src/ as output_.webp

Packaging / Publishing notes

• main entry: src/index.js
• remove node_modules and package-lock before publishing
