JSJ 394: SMS Integration with Dominik Kundel

JSJ 394: SMS Integration with Dominik Kundel

Episode SummaryDominik Kundel works as developer evangelist at Twilio. Dominik talks about the history of Twilio, which actually started with integrating phone calls into apps and then moved to SMS integration. Today Charles and Dominik are talking about how the SMS message approach can augment your user experience. Since many people are not familiar with implementing SMS, Dominik talks about how Twilio can help. Twilio created was a supernetwork where they work with carriers and gateways around the world to ensure that they provide reliable services. They also focus heavily on making sure that the developer experience is great.Uber and Lyft are two of the companies that use Twilio, and Dominik shares some of the interesting things that they’ve accomplished. He is particularly excited about phone number masking to support privacy. Uber and Lyft use phone number masking so that your driver doesn’t see your real number and you don’t see theirs. Instead, each of you sees a Twilio number. This use case is becoming more common. Twilio recently introduced Flex, which Dominik explains is their contact center solution. Flex is designed to keep with their philosophy of everything should be programmable and configurable, and take it on to a software shipment. This is their first time shipping software instead of just APIs. Flex is highly customizable and flexible, allows you to build React plugins that let you change anything you want.Charles asks Dominik about some of the gotchas in telephony. One major issues is spam calls, which Twilio is trying to work with some providers on a ‘verified by Twilio’ list. This list lets companies get verified, and they’re working on ways to let you know the reason why they’re calling without having to answer your phone. This can be difficult because each country has different regulations.Dominik talks about what it would take for someone who wanted to build an SMS gateway themselves. They would have to work with carriers and learn SMS protocols. It’s important to note that SMS and phone calls have different protocolsDominik talks about some of the unique use cases they’ve seen their system. Some examples are contextual communications, account verifications, and codex creation. There are other fun examples, such as a drone controlled via text message, a fake boyfriend app, and a dog that was taught to take selfies that are sent to his owner. Charles asks about ways to get started with Twilio. If you want to explore this and don’t know where to get started, try Twilio Quest, a game to teach you how to use Twilio. There is also documentation, which is good if you know exactly what you want to achieve, or if you just want to explore possibilities then download Twilio Quest. They delve into a more specific use case for Twilio to send text to subscibers of DevChatTV. Dominik talks about ways of dealing with sending notifications to people outside of the US. You can send with a US number to any country code, or you can personalize it, so that people in the UK receive it from a UK number and so on through automatic geocode matching. They talk about Twilio’s billing. Finally, they talk about security within telephony in light of recent hacks. They discuss the security of two factor authentication.Two factor authentication and security, especially in light of recent hacks. Dominik talks about the API called Authy, where you can implement different ways of doing two factor authentication, such as push notifications, time based one time password, sms, and phone calls. For most people in the world two factor authentication is very safe, unless you’re a very important person, then you’re more at risk for targeted attacks. They conclude by talking about Twilio’s acquisition of Sendgrid.Panelists

Replacing Create React App: Why Create TS Router App Is the Future of React Development - JSJ 675

Replacing Create React App: Why Create TS Router App Is the Future of React Development - JSJ 675

We’ve been diving into the evolving landscape of React app development and why tools like Create TS Router App (CTA) are stepping up to fill the gap left by the deprecation of Create React App (CRA). What we’ve learned is that SSR (server-side rendering) isn’t one-size-fits-all—e-commerce sites need it for SEO and performance, but internal tools and dashboards often don’t. That’s where CTA shines. It gives us a fast, modern, Vite-powered setup with TanStack Router built in, so we can start small and scale up without committing to heavy frameworks like Next.js from day one.What we love about CTA is how it keeps things familiar (same structure as CRA) while giving us type safety, file-based routing, and the flexibility to add only the features we need—like Clerk, Sentry, or even SolidJS support. Whether we’re building a simple prototype or a full-featured app, CTA makes the experience smoother, more intuitive, and future-friendly.Become a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.
