A simple Express app that lets you see texts to a Twilio number
This is set up to run on Heroku. Deploying is as simple as pushing the master branch to a Heroku app.
You'll need a TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, and TWILIO_PHONE_NUMBER.
forever -w server.js
The app will now be available at localhost:3000 and will update as you make changes to it. Note that you'll need the necessary Twilio environment variables for it to work.
You'll need a TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, and TWILIO_PHONE_NUMBER. It's recommended that you put these in the .env file. You can do this by copying the .env.example file to .env:
cp .env.example .env
and then filling in the necessary details.
Twilio uses webhooks to reply to messages. For development purposes you can use ngrok to make these webhooks available on the public internet.
In where-ever you've downloaded ngrok (probably ~/Downloads on a Mac), run:
./ngrok http 3000
This will assign you a random URL that you can then point your Twilio instance at. Note that every time you restart the subdomain of this URL will be different. One way of avoiding this is to pay for ngrok.
