After the Slack App is setup with the Slash command, run the below command to get weather information of a place.

/weather [<city>]

Additionally, you can avoid passing the city argument to get weather information of a random city from the list.

Run Offline

You can run the application on your local machine using deployctl.

OPEN_WEATHER_TOKEN=<token> deployctl run --libs=ns,fetchevent https://raw.githubusercontent.com/denoland/deploy_examples/main/slack/mod.ts

Grab a token at https://openweathermap.org and set the value for the variable.

To be able to use the local version on your Slack workspace, you need to use a tool like ngrok to tunnel Slack requests to the app running on your machine.

1. Run ngrok http 8000 (assuming that the application is running on port 8000)
2. Follow the steps under Installation section, but use the https URL output by ngrok for Request URL field.

That's it.
