Working with environment variable in Node.js is very easy and simple. Any mistake can lead your server to crash.

You have to make sure that your server is properly configured to make use of correct variables for both development and production environments. They always contains very sensitive data and doesn't meant to be shared with outside world. Hope y'all like it 🤞.Įnvironment variables are very fundamental part of developing with Node.js or any server side language. How do we load the values from this file? The easiest way is by using an npm module called dotenv.This is my first blog post. env.example or similar file is a common practice if you want to share a template file with other people in the project. env.example files, you can then copy them to. Typically, you don’t want to check these files into source control. These files allow you to specify a variety of different environment variables and associated values. A great way to achieve project-specific configuration is by using. For example, different messaging apps might need different Twilio Messaging Service SIDs, but both would be called TWILIO_MESSAGE_SERVICE_SID. If you develop multiple Node.js projects on one computer, you might have overlapping environment variable names. Overall, you should avoid overriding environment variables as much as possible and just initialize a configuration variable, as shown in the PORT example. However, keep in mind that this value is only set during the execution of this Node.js process and only available in child processes spawned by this process.

The code above will set or override the value of MY_VARIABLE. You can check if you already have Node.js installed on your machine by opening up a terminal and running the following:

This will include installing npm on a Mac and getting the environment ready for a Twilio project. We’ll then take you through the basics of setting up Node.js for use with Twilio on a Mac. We’ll review a few tricks and tools when working with environment variables in Node.js in this blog.įirst things first, we need to ensure that we have a Node.js environment. So while hosts will set a PORT variable that specifies on which port the server should listen to, modules might have different behaviors (like logging) depending on the value of the NODE_ENV variable. This opens up an array of ways to configure different aspects of your Node.js application.

So if you wanted to send an SMS, for example, you’ll need to install Node.js and the Twilio Node.js module.Īnother great feature of the Node.js language (and its modules) is that it has a neat way of working with environment variables, which many cloud hosts (such as Heroku, Azure, AWS, Now.sh, etc.) use. The reason for this is due to its event-driven, nonblocking input/output structure.Ĭombining it with Twilio makes building awesome telephony apps really easy. While still very young, Node.js has shown itself to be fast, highly-scalable, and efficient.

Node.js is one of the most talked about frameworks in the web development community since Rails. The basics of environment variables in Node.js

With just a few lines of code, you can simply run a Node.js application straight from the terminal and use Twilio to send and receive text messages with Twilio Programmable SMS.
