Send SMS to your users using Twilio in NodeJS in just a couple of steps.

Twilio provides programmable communication tools for making and receiving phone calls, sending and receiving text messages, and performing other communication functions using its web service APIs.

Here is how you can send an SMS using Twilio in NodeJS.

1. Create a Twilio account here https://www.twilio.com/try-twilio.

2. Folder Overview

   • Server.js is the entry point for our app.

   • app.js configures our application and dependencies for development

Conclusion

I think that Twilio is an excellent tool for sending SMS. It does have all the expected features for general app development, and it can be extended with the add-ons found in the marketplace. I have not yet used it for long-term projects since my side projects don't last long enough, but so far, I've been happy with it from the tinkerer's perspective. I would rather not spend my leisure coding time dealing with infrastructure.

Once again, thanks for reading, and I hope you found this helpful.
