Using the Consumer Template

The consumer directory in this repository serves as a template for new projects. It is included as a git submodule.

1. Clone the repository with submodules:

   git clone --recursive https://github.com/codebam/cf-workers-telegram-bot.git
   Copy

   Or, if you've already cloned it:

   git submodule update --init --recursive
   Copy

2. Copy the consumer directory:

   cp -r consumer my-new-bot
   cd my-new-bot
   npm install
   Copy

3. Configure your bot: Update wrangler.toml with your worker name.

4. Set your Telegram Token: Get a token from @BotFather and add it to your worker:

   npx wrangler secret put SECRET_TELEGRAM_API_TOKEN
   Copy

5. Deploy:

   npm run deploy
