Slack Weather Snippet

This magic piece of code allows you to retrieve the weather of a specified city using a Slack slash command.

For this you need:

• A Slack bot + a Slack slash command configured
• An OpenWeatherAPI account
• Ngrok for testing locally

Installation

To use this script, just follow the steps below:

git clone [email protected]:luis-at/slack-weather-app.git
pip3 install -r requirements.txt

Running the script

First, you need to create a vault.py file on the code directory, following the structure below:

SLACK_TOKEN = "YOUR_SLACK_TOKEN"
SLACK_SIGNING_SECRET = "YOUR_SIGNING_SECRET"
OPENWEATHERMAP_API_KEY = "YOUR_API_KEY"

Secondly, you need to run:

python3 main.py

Then, you should setup ngrok to listen and forward all the requests to configured Flask port (9002 in this case):

ngrok http --domain=YOUR_NGROK_DOMAIN 9002

If you have your Slack app and slash commands properly configured, you should now be able to run:

/jumo_weather Texas

And you should be seeing a reply. If you don't get any reply, it means that something is broken. Double-check the communication between Slack and ngrok, namely by checking that the configured domain matches the YOUR_NGROK_DOMAIN you used on the command above.
