Welcome to the JavaScript Guild!

As members of the JavaScript guild, you will be working through the challenges of TwilioQuest using server-side JavaScript, specifically node.js. This project is pre-configured to do some interesting Twilio stuff using node.js and the Express web framework.

Setting Up

We assume that before you begin, you will have node.js and npm and installed on your system. Before you can run this project, you will need to set three system environment variables. These are:

  • TWILIO_ACCOUNT_SID : Your Twilio "account SID" - it's like your username for the Twilio API. This and the auth token (below) can be found on the console.
  • TWILIO_AUTH_TOKEN : Your Twilio "auth token" - it's your password for the Twilio API. This and the account SID (above) can be found on the console.
  • TWILIO_PHONE_NUMBER : A Twilio number that you own, that can be used for making calls and sending messages. You can find a list of phone numbers you control (and buy another one, if necessary) in the console.

For Mac and Linux, environment variables can be set by opening a terminal window and typing the following three commands - replace all the characters after the = with values from your Twilio account:

export TWILIO_ACCOUNT_SID=ACXXXXXXXXX
export TWILIO_AUTH_TOKEN=XXXXXXXXX
export TWILIO_PHONE_NUMBER=+16518675309

To make these changes persist for every new terminal (on OS X), you can edit the file ~/.bash_profile to contain the three commands above. This will set these environment variables for every subsequent session. Once you have edited the file to contain these commands, run source ~/.bash_profile in the terminal to set up these variables.

On Windows, the easiest way to set permanent environment variables (as of Windows 8) is using the setx command. Note that there is no =, just the key and value separated by a space:

setx TWILIO_ACCOUNT_SID 'ACXXXXXXXXX'
setx TWILIO_AUTH_TOKEN 'XXXXXXXXX'
setx TWILIO_PHONE_NUMBER '+16518675309'

Running the application

Download the project source code directly or clone the repository on GitHub. Navigate to the folder with the source code on your machine in a terminal window.

You will first need to install the application's dependencies. You can do this using npm, the bundled package manager for node.js:

npm install

Now, you should be able to launch the application. From your terminal, run npm start. This should launch your Express application on port 3000 - visit that URL on your local host at http://localhost:3000. Enter your mobile number in the fields provided, and test both SMS text messages and phone calls being sent to the mobile number you provide.

If your phone receives both a call and text message, you're good to go!

Begin Questing!

This is but your first step into a larger world. Return to TwilioQuest to continue your adventure. Huzzah!
