This is an application example implementing Click to Call using Twilio. For a step-by-step tutorial, visit this link.
Implementations in other languages:
.NET | Java | Python | Ruby | PHP |

Done | Done | Done | Done | Done |
- Nodejs v10 or v12
This application should give you a ready-made starting point for writing your own application. Before we begin, we need to collect all the config values we need to run the application:
Config Value | Description |
---|---|
TWILIO_ACCOUNT_SID | Your primary Twilio account identifier - find this in the Console. |
TWILIO_AUTH_TOKEN | Used to authenticate - just like the above, you'll find this here. |
TWILIO_NUMBER | A Twilio phone number in E.164 format - you can get one here |
-
First clone this repository and
cd
into it.git clone https://github.com/TwilioDevEd/clicktocall-node.git cd clicktocall-node
-
Install the dependencies.
npm install
-
Copy the sample configuration file and edit it to match your configuration.
cp .env.example .env
See Twilio Account Settings to locate the necessary environment variables.
-
Launch local development web server, will run on port 3000.
npm start
-
For Twilio to be able to talk to your application, you'll need a way to make your server publicly available to the internet. For local testing purposes, we recommend using ngrok. Ngrok provides secure introspectable tunnels to localhost webhook development: for more information and instructions on setting up ngrok to work with your application, check out this section of the Click to Call tutorial.
ngrok http 3000
-
Finally, open up your browser and go to your ngrok URL. It will look something like this:
http://<sub-domain>.ngrok.io
That's it!
If you have Docker already installed on your machine, you can use our docker-compose.yml
to setup your project.
- Make sure you have the project cloned.
- Setup the
.env
file as outlined in the Local Development steps. - Run
docker-compose up
. - Follow the steps in Local Development on how to expose your port to Twilio using a tool like ngrok and configure the remaining parts of your application.
To execute tests, run the following command in the project directory:
npm test
Additionally to trying out this application locally, you can deploy it to a variety of host services. Here is a small selection of them.
Please be aware that some of these might charge you for the usage or might make the source code for this application visible to the public. When in doubt research the respective hosting service first.
