How to filter updates with allowed_updates?

[sidelux]

I read days ago new api version where telegram now take possibility to filter incoming update with allowed_updates in getUpdates method.
How can i write this method correctly to receive only text messages and edited messages?

Thanks a lot!

This feature would certainly be useful 👍

---

First, the current implementation of the TelegramBot#getUpdates() does not allow us to pass the allowed_updates parameter. This is being addressed in PR #245. (DONE)

---

Second, we need a way to provide parameters to be re-used during polling, in our Constructor. For example,

const bot = new TelegramBot(token, {
  polling: {
    // parameters reused in each request during polling
    params: {
      "allowed_updates": ["message", "edited_channel_post", "callback_query"],
    },
  },
});

This will also allow us to pass an offset to determine the first update to be pulled. However, it should be updated after each poll interval! This will close issue #14!

(DONE — commit)

@GochoMugo or, instead of allowing users specify which updates they wanna receive, what about building that list based on the updates they listen to?

this.allowedUpdates = [];
on(event, callback) {
    super(event, callback);
    this.addAllowedUpdate(event);
}
addAllowedUpdate(event) {
    if (!this.allowedUpdates.includes(event) {
        this.allowedUpdates.push(event);
    }
}
onText() {
    // other stuff
    addAllowedUpdate('message');
}

I have just added this enhancement (in commit e75d51ca8fe46059e78a74e1ece7787c881157cb). Please try out the updated master branch's code to see this feature in action. See documentation on options.params.

@GingerPlusPlus Sorry, I felt your way being too complex. We would have to coordinate when polling starts and when are done scanning for the allowed updates. However, we can discuss more on it, in depth (preferably in an entirely new issue).

Shipped in v0.27.0.

Thanks @sidelux and @GingerPlusPlus for contributing to this feature.
