❌ error 🖐️ling (Portland, OR)

In the era of async/await, the grass has never been greener over here in Node.js-land. But when fostering a stable code base, there are still a few major gotchas you need to watch out for, and some of them are less than obvious. Mike will review the most common practical risks and annoyances teams tend to encounter in real-world #javascript applications, as well as his favorite best practices for avoiding those mistakes.

He'll pay special tribute to "parley" (https://lnkd.in/eezaxux), the highly-optimized #stability library that powers async/await usage in Sails & other Node.js packages. You'll learn best practices to streamline common pain points: error negotiation, tolerance (conditional swallowing), retries, timeouts, and interceptions (but, like, for upstream services ☁️, not 🏈).

Mike McNeil (@mikermcneil) has been an avid business user and evangelist for #nodejs for the last eight years. He's also the creator of Sails.js, a popular open-source MVC framework that's kind of like Rails for Node.js.

6. Overly complex async logic
   Usually, you don't need this. Even at high
   scale, there are other, much more
   immediately-relevant performance and
   scalability bottlenecks.
