The Slack Bot Mention Edge Function allows you to process mentions in Slack and respond accordingly.
|
|
|
|
## Configuring Slack apps
|
|
|
|
For your bot to seamlessly interact with Slack, you'll need to configure Slack Apps:
|
|
|
|
1. Navigate to the Slack Apps page.
|
|
1. Under "Event Subscriptions," add the URL of the `slack-bot-mention` function and click to verify the URL.
|
|
1. The Edge function will respond, confirming that everything is set up correctly.
|
|
1. Add `app-mention` in the events the bot will subscribe to.
|
|
|
|
## Creating the Edge Function
|
|
|
|
Deploy the following code as an Edge function using the CLI:
|
|
|
|
```bash
|
|
supabase --project-ref nacho_slacker secrets \
|
|
set SLACK_TOKEN=<xoxb-0000000000-0000000000-01010101010nacho101010>
|
|
```
|
|
|
|
Here's the code of the Edge Function, you can change the response to handle the text received:
|
|
|
|
```ts index.ts
|
|
import { WebClient } from 'https://deno.land/x/slack_web_api@6.7.2/mod.js'
|
|
|
|
const slackBotToken = Deno.env.get('SLACK_TOKEN') ?? ''
|
|
const botClient = new WebClient(slackBotToken)
|
|
|
|
console.log(`Slack URL verification function up and running!`)
|
|
Deno.serve(async (req) => {
|
|
try {
|
|
const reqBody = await req.json()
|
|
console.log(JSON.stringify(reqBody, null, 2))
|
|
const { token, challenge, type, event } = reqBody
|
|
|
|
if (type == 'url_verification') {
|
|
return new Response(JSON.stringify({ challenge }), {
|
|
headers: { 'Content-Type': 'application/json' },
|
|
status: 200,
|
|
})
|
|
} else if (event.type == 'app_mention') {
|
|
const { user, text, channel, ts } = event
|
|
// Here you should process the text received and return a response:
|
|
const response = await botClient.chat.postMessage({
|
|
channel: channel,
|
|
text: `Hello <@${user}>!`,
|
|
thread_ts: ts,
|
|
})
|
|
return new Response('ok', { status: 200 })
|
|
}
|
|
} catch (error) {
|
|
return new Response(JSON.stringify({ error: error.message }), {
|
|
headers: { 'Content-Type': 'application/json' },
|
|
status: 500,
|
|
})
|
|
}
|
|
})
|
|
```
