Telegram Stickers API

This is basically a wrapper around the Telegram Bot API that only provides access to sticker data.

It aggressively caches sticker image data both on-disk and in the Cache-Control header, both to save requests to Telegram and to save requests from clients.

It is suitable for public use -- no API tokens are required.

Features

Public sticker API
Automatically handles WebP -> PNG conversion
Aggressive file caching for fast response times
Pre-set CORS headers -- use it in client-side JS immediately

Usage

Create config.json:

{
  "BOT_TOKEN": "Something",
  "CACHE_TIME": 3600
}

Then:

npm install
node index

In production, you can use environment variables instead of config.json.

Then, simply use these endpoints:

GET /pack/:name
GET /sticker/:id.png

Examples:

(Please do not use stickers.horner.tj in production. It is not stable and may go down at any time. It is simply for demonstration purposes.)

Docker

A Dockerfile is included in this repo, but prebuilt images are available:
