Congratulations! You've successfully created a HipChat Connect Add-on using the Express web application framework.
Install your dependencies.
npm install
On a separate terminal, start up an ngrok tunnel to port 3000.
ngrok http 3000 # if you've got ngrok installed globally
or
./node_modules/ngrok/bin/ngrok http 3000 # local dependency
Copy the https forwarding URL. e.g. https://cace28ac.ngrok.io
AC_LOCAL_BASE_URL=https://cace28ac.ngrok.io node app.js
Your add-on should now be running on localhost:3000 and forwarded to the ngrok https URL.
Use the ngrok https URL to install the add-on to a HipChat room.
