In this series, I explain how to use Twitch EventSub and Courier to automatically send notifications to multiple destinations – Slack, Discord, and more – when your Twitch stream goes live. In part one, we built a Node.js app using Express.js to accept events from Twitch EventSub. Now, in part two, we’re going to listen for our event and trigger a notification using Courier.

Today, we’re excited to announce the release of Environments in Courier. You can now create, preview, and troubleshoot your notifications in a test environment before going live. With support for two environments – Test and Production – you no longer have to worry about accidentally sending a notification to your users before you’re ready.

Over the last few years, Twitch has become the streaming platform for gaming, esports, live coding, DJ-ing, and more. If you’re a streamer, whether for work or for fun, you know that one of the biggest challenges is building your audience and attracting viewers to your Twitch channel when you go live. Unfortunately, the options for sending notifications in Twitch are pretty limited. When you go live, Twitch will automatically send your followers an email, push, or in-app notification.

I recently joined Courier as a Software Engineer and part of the onboarding process was to set up and configure my development environment on the new M1 MacBook Pro. This task was more complicated than usual because, with the new MacBooks, Apple has replaced their long-running Intel processors with their own M1 chip. To help you take full advantage of the power of the new MacBooks, here are some tips and tricks I picked up when setting up my own machine.

On January 6, Riley Napier joined me for our first Courier Live of the new year. Having recently set up webhooks using Twitch EventSub, I wanted to walk through how you could trigger notifications about your Twitch livestreams using Courier. We did this using a Glitch application and explained how to set it up and start accepting requests from Twitch.

Notifications are an essential part of every application. They’re how products communicate with users when key events take place, whether it’s confirming their account or alerting them to new activity. But, for developers and companies, delivering notifications that meet their users’ rising expectations can be a challenge. Today, users expect you to notify them on the channels where they already are, at exactly the right moment and with respect for their individual preferences.
