Telegram Wallpaper maker

A telegram bot written with Telegraf.js that turns any image sent into a fitted phone wallpaper with a blurry background.

The project uses Docker, to make the setup easier.

Credits to @MakotoIchinose6 for the image of Clive they made that I use for the preview. (I'm absolutely in love)

Requirements

• Docker

or if you are planning to run the script yourself

• NodeJS >= v18.0.5

Setup

Using Docker

1. Create a token for the bot through BotFather

2. Get the docker image:

docker pull kiwipetal/telegramwallpapers:latest

3. Run the docker image:

docker run -d -e BOT_TOKEN="YOURTOKEN" kiwipetal/telegramwallpapers:latest

Manual

1. Pull the repository.

2. Install all dependencies:

npm install
# or
yarn

3. Create a token for the bot through BotFather

4. Create an .env file:

BOT_TOKEN=YOURTOKEN

5. Run the script

npm run start
# or
yarn start

Usage

Send a number to change the blur strength (default: 200). The package for blurring seems to break if you go above 300 though (Will fix that later).

Send an image (not as a file). The bot will respond with an edited version.

TODOs

• Script to Make images
• Custom intensity
• Docker integration
• Feature flag to opt out of session persistence
• Custom resolution
