Facebook messenger chatbot to evaluate crypto currencies

To start your Phoenix server:

• Install dependencies with mix deps.get
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.

To run bunny bot inside docker on local machine, run the following commands

Build the docker image

docker build -t bunny-bot:version-init .

Run the application inside docker container

docker run -d -e FB_PAGE_ACCESS_TOKEN=[put_fb_page_token_here] \
-e FB_WEBHOOK_VERIFY_TOKEN=[put_fb_webhook_verify_token_here] \
-p 4000:4000 \
--name bunny-bot bunny-bot:version-init

OR

Run the shell-script to run bunny bot inside docker container

./deploy-docker.sh

Run following commands to run tests using mix test utility

mix test

mix test test/crypto_bunny

mix test test/crypto_bunny_web/controllers

To make sure Facebook messenger communicate with bunny bot either running locally or on production, set the following webhook url with the webhook verify token same as in app configuration.

http://localhost:4000/api/facebook-webhook

If the application is running on local machine, we cannot use localhost address directly. To expose localhost on internet, we can take advantage of port-tunneling using Ngrok. Now webhook url would look like

https://65db-119-160-99-97.ngrok.io/api/facebook-webhook
