How to Build a Slack Bot

Slack is a great chat and communication tool used by small and large businesses as well as personal use. Slack has a great API and great official Node JS clients that help you automate many features of Slack. If you're thinking of building a bot for Slack, be sure to follow this step by step tutorial on how to build a Slack bot in JavaScript using the Slack API and the Node Slack SDK. With this SDK, we can connect to the Slack Web API and even hook into events using the RTM API and build a bot in just a few minutes that you can add to your Slack server today.

Nice video. One suggestion: I would add an annotation/link to your "Setting Up Windows for JavaScript Development THE RIGHT WAY" video at 03:23 Start Writing Code. I hadn't seen your description while watching your video for the first time and I was immediately lost at that chapter.

[adrianjason]

Hey man. Grateful to have found your tutorial! Really helpful. I've got an issue though. My bot is not appearing as online even though I got the "Always Show My Bot as Online" enabled. Any thoughts? Thanks and cheers!

[alexanders]

Hey Tim, great Video. Could you maybe make a Video about the Ticketsystem „Zammad“ or about the knowledgebase System „xWiki“?

[tiagoalexandrino]

Hello!

Thank you so much for this great Tutorial!

Unfortunately, i'm having a small problem... When i type "!Hello" at Slack, the Bot answers me the same message 5 times in a row... and i can't understand why. Could you give me a little help please?

Thanks in advance!

[Lysiak.Yevhenii]

Thanks a lot ! Very good explanation !

[ljohnso]

I used to program a lot of PHP code, and am familiar with server side code, but how do i install this on a web server so i can run it in production not just on my main machine. Your tutorial for how to configure my windows environment was nice, a few version updates made me search for a few answer but i got there.

[alokpradhan]

Nice tutorial but rtm-api is deprecated . Can you create same tutotial in socket Mode using @Slack/bolt package? Thanks and happy Learning!!

Hey Techno Tim,

After starting up the bot at 8:39, I get the following error message:

*/
TypeError: Cannot read properties of null (reading 'message')
at callback
at afterWrite
at onwrite
at WriteWrap.onWriteComplete [as oncomplete]

/*

Do you know what I can do next?

[webmandman]

Yo TechnoTime, its been a year since you published this. and I don't see a classic app option. What gives?

[JeDeXxRioProKing]

LIKE --> Comment, before Watching video I know it will be something good

[martincarrascofilippi]

I'm working on a bot that sends request to my private API to create some data on my DB and they are mounted both on the same server. Do you recommend this or should I mount both of them as different applications?

[creechavo]

One question. Can you do a video in how to host/create a game server in proxmox if it's possible to do it in that. If not then with a reliable solution to host gaming servers on one server machine.
