  2. What about the lambda pricing? if a lambda its triggered in every client's message sent, wouldn't it be expensive? assumingly an app in a very large scale…

  5. Hola , de casualidad no tendrás un curso en udemy con websokets y serverless ya que tengo el tuyo pero no cuenta con esta característica

  10. Hi, thanks for the great tutorial!! Idle time(10min) and max connection(2hr) still an issue for realtime application. What would be the best way to handle this for a real-time application to make sure all client is always connected when server need to send message? Heartbeat?

  11. Hola! Marcia, a mi me manda el error "error: Unexpected server response: 502" desde wscat, desde una pagina web. Hice todo manual desde la consola, implemente la api y la probe me sigue marcando 502. Te suena el error? que crees que pueda ser? El log dice: 2019-06-14 13:55:05.513 (-05:00) undefined ERROR Uncaught Exception {"errorType":"ReferenceError","errorMessage":"event is not defined","stack":["ReferenceError: event is not defined"," at Object.<anonymous> (/var/task/handler.js:13:12)"," at Module._compile (internal/modules/cjs/loader.js:701:30)"," at Object.Module._extensions..js (internal/modules/cjs/loader.js:712:10)"," at Module.load (internal/modules/cjs/loader.js:600:32)"," at tryModuleLoad (internal/modules/cjs/loader.js:539:12)"," at Function.Module._load (internal/modules/cjs/loader.js:531:3)"," at Module.require (internal/modules/cjs/loader.js:637:17)"," at require (internal/modules/cjs/helpers.js:22:18)"," at _tryRequire (/var/runtime/UserFunction.js:75:12)"," at _loadUserApp (/var/runtime/UserFunction.js:95:12)"]}

  12. I'm having a very difficult time trying to find good examples/tutorials of using API Gateway Websockets with Cognito (bonus for Serverless framework + Cloudformation)…

  13. Why after changes of yml file, at the end, i dont get endpoint anymore, it response with 'endpoints: none' ?
    I suggest to do some debug-setup tutorial with RDS/mySql db, beacuse its little confusing and 99% of using these services is all about do proper config and setup.
    Good tutorial! 🙂 Thumb up!

  14. a very good tutorial.
    i would like to know how api websockets work with a service like athena or ECS task could you please help me. that will great.
    Thanks you,
    Vamse.

  18. Hello , This was a really helpful video. I really need your help to make a chat application whose frontend I have already designed using Angular 6 and Need a AWS websocket api gateway to enable multiple users to chat. However I fall out of resources to learn. I shall be very thankful if you can demonstrate how to connect this API gateway to frontend and begin chatting. That video would be something "on demand". 🙂

  19. Hi thanks for this great article. Can we use single serverless.yml which can deploy both http and websocket API together and want to specify deployment role in each function.
