File handling simplified in grammY

This plugin allows you to easily download files from Telegram servers. Check out the official plugin page for further documentation.

Example

import { Bot, Context } from 'grammy'
import { hydrateFiles, FileFlavor } from '@grammyjs/files'

// Transformative API flavor
type MyContext = FileFlavor<Context>

// Create bot
const bot = new Bot<MyContext>('')

// Install plugin
bot.api.config.use(hydrateFiles(bot.token))

// Download videos and GIFs to temporary files
bot.on([':video', ':animation'], async ctx => {
    // Prepare file for download
    const file = await ctx.getFile()
    // Download file to temporary location on your disk
    const path = await file.download()
    // Print file path
    console.log('File saved at', path)
})

You can pass a string with a file path to download if you don't want to create a temporary file. Just do await file.download('/path/to/file').
