Node.js
The twilio-node library is available on npm, which is Node's package manager that is included when you download Node itself.
To install the library, run npm install twilio --save in your project directory, or npm install –g twilio to install it globally across your machine.
In your code, you'll just need to require the library and instantiate a client (client.js):
var account_sid = process.env.TWILIO_ACCOUNT_SID;
var auth_token = process.env.TWILIO_AUTH_TOKEN;
var client = require('twilio')(account_sid, auth_token);The syntax for sending an SMS from this point onwards is similar to Ruby, using a dictionary of arguments.
However, there is a complication in that Node uses asynchronous requests when contacting the API, meaning that we can't simply save what the method returns to a variable. Instead, we provide a callback that will be invoked with the Message object once it has been sent successfully (send_sms.js):
client.messages.create({
body: "This is an SMS message.",
to: "+441708300116...
