Send message as a bot directly to the user (define user access_hash)? about airgram HOT 11 CLOSED

You usually can obtain access_hash from the users field of some updates.

import { ag, api } from 'airgram'

airgram.updates.use((ctx: ag.UpdateContext<any>, next) => {
  if ('users' in ctx.update) {
    ctx.update.users.forEach((user: api.UserUnion) => {
       // save user.access_hash to somewhere
    })
  }
  return next()
});

Ok. Got it.
I get full updates event, that includes updateNewMessage.
Full updates event object:

{ _: 'updates',
  updates:
   [ { _: 'updateNewMessage',
       message: [Object],
       pts: 570,
       pts_count: 1 } ],
  users:
   [ { _: 'user',
       pFlags: {},
       flags: 4194411,
       id: 123456789,
       access_hash: '999999...999',
       first_name: '...',
       username: '...',
       photo: [Object],
       status: [Object],
       lang_code: 'ru' },
     { _: 'user',
       pFlags: [Object],
       flags: 17419,
       self: true,
       bot: true,
       id: 999999999,
       access_hash: '999999...999',
       first_name: '...',
       username: '...',
       bot_info_version: 1 } ],
  chats: [],
  date: 1544620388,
  seq: 0 }

@esindger If I do not want to use all updates middleware, but only updateNewMessage, in ctx.update I get only "nested update":

{ _: 'updateNewMessage',
       message: [Object],
       pts: 570,
       pts_count: 1 }

However full update event is:

{ _: 'updates',
  updates:
   [ { _: 'updateNewMessage',
       message: [Object],
       pts: 570,
       pts_count: 1 } ],
  users:
   [ { _: 'user', ... },
     { _: 'user', ... } ], }

Is it possible to get access to "full" update event inside updateNewMessage handler?
E.g. ctx.client.a.b.c.fullUpdateEvent

Nice to see fast support in this project! Thanks.

Actually, maybe I do not need "full" event object with users. What I need is "simple" reply() function.
Like in Telegraf reply().

  reply (...args) {
    this.assert(this.chat, 'reply')
    return this.telegram.sendMessage(this.chat.id, ...args)
  }

This function is used in a lot of examples:

bot.start((ctx) => ctx.reply('Welcome'))
bot.help((ctx) => ctx.reply('Send me a sticker'))
bot.on('sticker', (ctx) => ctx.reply('👍'))

The same I want to achieve with Airgram (however Airgram will be more powefull, so I can use it for bot and fo user). E.g. somewhere in updateNewMessage handler:

type OnlyOneMessageUpdateContext = /* here I want context that will contain only one message at time, so airgram will easily detect to which message it must reply */ UpdateContext;

airgram.updates.on(`updateNewMessage`, (ctx: OnlyOneMessageUpdateContext) => {
  if (update.message === '/start') {
    await ctx.reply('Hello!');
    await ctx.reply('Nice to meet you!'); // reply to the same message twice
  }
});

1. Airgram should detect to whom airgram must reply (whether message was sent from chat or directly from user). I see that using bot API is much simpler in this case, just to use sendMessage and send chat or user id. With MTProto (Airgram) this will be harder task.
   Probably detect message type as

to_id: { _: 'peerChat', chat_id: ... } // then reply to chat
to_id: { _: 'peerUser', user_id: ... } // then reply to user

2. Because of async handlers I should be confident that current context contains the same message (the same users array).

But anyway, if I will get access to users array in updateNewMessage I will try to implement reply() function on my own.

Since v0.1.9 you have access to the parent update by ctx.parent property.

airgram.updates.on(`updateNewMessage`, (ctx: ag.UpdateContext) => {
  console.log(ctx.parent)
});

from airgram.

For now, there is no plan to implement reply() function but we can refactor code to put creating of context into separate method createContext. Then you will be able to inherit this method and extend context.

Awesome! Thanks!

Got it. If you will make it - it would be nice.

@esindger

airgram.updates.on(`updateNewMessage`, (ctx: ag.UpdateContext) => {
  console.log(ctx.parent)
});

In typescript I get compile error:

[ts] Property 'parent' does not exist on type 'UpdateContext<UpdatesResponse>'. [2339]

Am I missing something?

Please check out package.lock which version is installed. This will work start from version 0.1.9.

from airgram.

Now you can extend updates context. Please check out the example

Yep. With version 0.1.9 removed package-lock.json and run npm i - helped. Thanks!
