A fledgling calendar bot to showcase Opal. It currently connects to Slack and uses Wit for NLU.

Here's how to get it running:

1. npm install (or yarn) and then tsc.
2. Obtain a Wit API token. Put this in the WIT_ACCESS_TOKEN environment variable.
3. Obtain a Slack bot access token. Put this in the SLACK_BOT_TOKEN environment variable.
4. To run on Facebook Messenger too, do the incredibly complicated dance to obtain Facebook credentials. Set the FB_PAGE_TOKEN variable for your bot and the FB_VERIFY_TOKEN variable to the string you chose when setting up your webhook.
5. Run node build/bot.js. Use -s to run on Slack or -f to run on Facebook. (Both can work at once.)

Or, you can run a local version for fun by skipping the Slack token and providing the -t flag (for terminal).

Because there are a lot of environment variables involved, you might want to put them in a .env file. If you do that, you can run the bot using a convenient Make target:

$ make run ARGS=-t
