# 🦉 Jia
|
||
|
||
Keeping an eye on the Hack Club Slack’s [#counttoamillion](https://hackclub.slack.com/archives/CDJMS683D) channel.
|
||
|
||
## Setup
|
||
|
||
### Creating the Slack app
|
||
|
||
You’ll need to create a Slack app (not a classic one) with at least the following bot token scopes. The reasons each scope is required are also included:
|
||
|
||
- `channels:history` (or `groups:history`, if it’s a private channel): Used to listen to messages sent.
|
||
- `chat:write`: Used for sending messages.
|
||
- `reactions:write`: For reacting to invalid messages.
|
||
|
||
Then you’ll need to subscribe the app to a few events. The server has an endpoint open at `/slack/events`, so when you’re asked for a request URL, just put `https://<SERVER>/slack/events`. Only the following events are needed:
|
||
|
||
- `message.channels` (or `message.groups` if it’s a private channel)
|
||
|
||
### Environment variables
|
||
|
||
Here are all the variables you need to set up, with hints.
|
||
|
||
```bash
|
||
# The port to run the app server on
|
||
PORT=3000
|
||
# Redis database to store the last number and its sender
|
||
REDIS_URL=redis://…
|
||
# App config. Obtained from the "Basic Information" page of your app.
|
||
SLACK_CLIENT_BOT_TOKEN=xoxb-…
|
||
SLACK_VERIFICATION_TOKEN=xxxx…
|
||
# The channel where Jia should validate counted numbers in.
|
||
SLACK_CHANNEL_ID=C…
|
||
```
|
||
|
||
### Deploying
|
||
|
||
```bash
|
||
# Run it…
|
||
make
|
||
|
||
# …or build a binary and run that instead
|
||
make build
|
||
./bin/jia
|
||
```
|
||
|
||
After you’ve followed all the above steps, you should see something like this:
|
||
|
||
```bash
|
||
Starting Jia…
|
||
Listening on port 3000
|
||
```
