This Slack bot annoys you in conversations. The bot mixes up words in your conversation by making use of the Google Cloud Natural Language API.
This bot is build with the botkit.ai Botkit.
Go to http://my.slack.com/services/new/bot and copy the API token.
Update heroku-config.sh (is executed later on).
Create a new Service Account and create and download a Private Key in JSON format.
Copy project ID and client email from the JSON file to heroku-config.sh
Base64 encode the private key from within the .json using encode-base64.js and copy that value as well.
Follow https://devcenter.heroku.com/articles/git:
Create a new node App through the Heroku online console and connect it with this repo with
heroku git:remote -a <app-name>
Set env variables for the app with `heroku-config.sh from above.
Create and connect a redis instance with
heroku addons:create heroku-redis:hobby-dev
Make sure the app has now a REDIS_URL environment variable set by heroku.
With
git push heroku master or if the GitHub repo is connected to Heroku (see below) simply git push.
Make sure no web but a worker process of this app is started (refer to Procfile).
In case heroku ps does not state a single worker is running do:
heroku ps:scale web=0
heroku ps:scale worker=1
If everything is fine heroku ps should look like this:
=== worker (Free): npm start (1)
worker.1: up 2017/07/15 22:46:57 +0200 (~ 10m ago)
If the project is on GitHub, the repo should have an origin and a heroku remote:
$ git remote -v
heroku https://git.heroku.com/<heroku-app>.git (fetch)
heroku https://git.heroku.com/<heroku-app>.git (push)
origin https://github.com/<user>/<repo>.git (fetch)
origin https://github.com/<user>/<repo>.git (push)
In this case you can connect the GitHub repo within the heroku app and enable automatic deploys on pushes to the remote origin.
