"Be not afraid!"

In the era of async/await, the grass has never been greener over here in Node.js-land. But 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 mistakes our team sees in real-world Node.js applications. And then he'll explain why it's actually fine... why, despite all that, Node.js is even more of an awesome choice for your application in 2019.

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

  5. What's wrong with Node.js?

  6. What's wrong with some Node.js apps?

  7. 1. Not using await

  8. 1(A). Throwing in callbacks

  9. 1(B). Ignoring errors in callbacks or in promise chains

  10. 1(C). Not using await... on purpose (drinking performance kool-aid)

  11. 1(D). Not using await... on accident

  12. 2. Not handling 'error' events

  13. 3. Lack of structure

  14. 3(A). Named functions being declared all over the place

  15. (in our server-side Node.js code, if we give a function

    a name, then we also give it its own file)
  16. 3(B). Not having a way of figuring out all the

    places where a given function is being called from
  17. (can you grep for it?)

  18. 3(C). Insufficient abstraction

  19. (express is a fantastic "build your own framework" framework)

  20. 4. Fetching WAAAAYYY too many things at the same time

  21. 5. Fetching a normal amount of things…but WAAAYYYY too many

    times
