PR Summary

Handle reaction_added messages

Converts reaction_added messages to TextMessages before passing them to Hubot. Used to implement behavior needed by 18F/hubot-slack-github-issues and depends on behavior from slackapi/node-slack-sdk#96, which may be out-of-date by now. I'll take a look at the latest version and report back when I get a chance tonight or tomorrow, unless someone else already has context and beats me to it.

Related Issues

Supercedes and closes #271. Also pertains to #251.

Test strategy

Unit tests to validate the new SlackBot.reactionAdded method as part of the existing Handling incoming messages suite.

Hello @mbland ! This looks quite nice, thank you for taking the time to update your PR!

However, I have one complaint. Rather than emitting a TextMessage, the current paradigm is to emit a new kind of message, so that clients can select what kinds of events they respond to. Look at bot.coffee:137–ff. I would recommend creating a ReactionMessage that specifies what happened in a structured way (what reaction? what message? was it added or removed?) rather than overloading TextMessage to accomplish this.

Thoughts?

mtlewis · 2016-09-20T07:51:27Z

@mbland thanks so much for picking this back up!

@DEGoodmanWilson I was secretly hoping you'd suggest something like that. Done.

The reason I held back originally (other than trying to keep parity with the existing #271 while I re-familiarized myself with the code) was because I noticed all the existing message types are imported from the hubot npm. Would the long-term plan, then, be to add this message type upstream? I'm happy to send out another PR to github/hubot to do that if you think that makes sense.

Also, looking back at slackapi/node-slack-sdk#96 and https://github.com/slackhq/node-slack-sdk/blob/3.4.0/lib/clients/rtm/client.js, it looks like the reaction_added and reaction_removed events are emitted by default, as with every other event type. Consequently, everything should "just work", modulo pushing the ReactionMessage class upstream.

johnagan · 2016-09-20T16:29:10Z

LGTM 👍

great work!

UncannyBingo · 2016-09-20T17:56:47Z

Yeah, this is great. I would advise against adding these types upstream in Hubot. Not all messaging services provide this kind of functionality, and to my mind at least, platform-specific features should remain with the adapter. Because, let's be honest, a Hubot script or plugin that makes use of this message type is simply not going to work on another service.

Merging this in, will release…soon. I promise.

mbland · 2016-09-20T18:29:06Z

Cool, thanks! (And I was tilting towards the same conclusion re: pushing ReactionMessage upstream.)

mbland · 2016-09-21T20:21:20Z

Looks like this just got pushed in v4.1.0. Thanks, @DEGoodmanWilson and @johnagan!

neufeldtech · 2016-10-03T17:12:05Z

Hi there @mbland,
I've scanned the code in your PR, but I'm still unsure on how to actually implement reaction handling in a hubot script. Would you care to provide a simple "hello world" example on how to get hubot to listen for reaction_added messages? Thanks!

mbland · 2016-10-03T19:21:45Z

@neufeldtech I'll try to get to it in the next day or two. Feel free to ping me by Friday if I haven't posted back.

FWIW, the original hack was to hook into the receiveMiddleware mechanism, and when a message came through, check the message type (reaction_added) and item type. I need to update that plugin as well, so I'll try to both knock it out and the "Hello, World!" example at the same time.

mbland · 2016-10-05T22:27:46Z

@neufeldtech OK, here you go: https://github.com/mbland/hubot-slack-reaction-example

neufeldtech · 2016-10-05T22:35:40Z

@mbland Thanks! I'll be sure to take a look at this.

mbland · 2016-10-06T02:31:11Z

Not to drag this thread out too long, but...I've already updated the example script to be even smaller and easier to follow.

And @DEGoodmanWilson: Do you think it'd be worth patching on a robot.react during SlackBot.run, so that clients won't have to require the ReactionMessage type or define the (message) -> message instanceof ReactionMessage matcher at all? (Happy to supply the PR myself, of course.)

UncannyBingo · 2016-10-06T16:47:08Z

@mbland That might be a good idea, actually!

Per slackapi#360, this is the first step towards implementing a `robot.react` method based on: https://github.com/mbland/hubot-slack-reaction-example/blob/v1.1.0/scripts/handle-reaction.coffee The previous Hubot development dependency version was ~2.11, but the `robot.listen` method didn't appear until v2.16.0: hubotio/hubot#986 hubotio/hubot#1035

Per slackapi#360, this implements `robot.react` as a replacement for the approach from: https://github.com/mbland/hubot-slack-reaction-example/blob/v1.1.0/scripts/handle-reaction.coffee Specifically, the `ReactionMessage` definition will no longer be required in client code, and this: robot.listen( (message) -> message instanceof ReactionMessage handleReaction ) can now become: robot.react handleReaction `robot.react` can also take optional `matcher` and `options` arguments just like the underlying `robot.listen` method: robot.react( (message) -> message.type == 'added' && message.reaction == '+1' {id: 'my-reaction-matcher'} handleReaction )

mbland · 2016-10-06T20:58:40Z

OK, just filed #363. Anyone who's still interested can subscribe to that PR.

Thanks to the new @slack/client npm, slackapi/hubot-slack#360, and slackapi/hubot-slack#363, the `SlackBot` will now emit a `ReactionMessage` object for `reaction_added` and `reaction_removed` events. A future commit will repackage the logic so that it is no longer middleware, but called as part of a `robot.listen` or `robot.react` callback.

mbland · 2016-10-14T16:23:39Z

FYI @neufeldtech (and others), with the merge of #363 and release of v4.2.0, robot.react is now live. I've updated my hubot-slack-reaction-example to use it (as well as trimmed down the instructions), so you may want to look at it again.
