This file is a log of everything I've encountered when trying to migrate a Node.js, Elastic Beanstalk application from the Amazon Linux platform to the Amazon Liunx 2 platform. Here's why you should migrate:

1. LTS support up to 2023 source
2. The Amazon Linux AMI's end-of-life is December, 2020 source
3. Amazon Linux 2 has some big package upgrades (GCC, Glibc, etc.)
4. Elastic Beanstalk also has some upgrades on top of Amazon Linux 2 (e.g. faster deploys)

##Using Let's Encrypt certificates with AWS API Gateway

Before starting off with API Gateway set up it's worth mentioning that certificate configuration for this particular service is so far isn't well integrated, therefore different from other AWS services. Despite it using CloudFrount to serve on custom domains it won't let you customize distributions it creates, however all the limitations of CloudFront naturally apply to API Gateway. The most important in this case is the size of the key, which is limited by 2048 bit. Many tutorials provide ready to use terminal commands that have the key size preset at 4096 bit for the sake of better security. This won't work with API Gateway and you'll get an error message about certificate's validity or incorrect chain which won't suggest you the real cause of the issue. Another consideration is that to add a custom domain to API Gateway you have to have a certif

From Meteor's documentation:

In Meteor, your server code runs in a single thread per request, not in the asynchronous callback style typical of Node. We find the linear execution model a better fit for the typical server code in a Meteor application.

This guide serves as a mini-tour of tools, trix and patterns that can be used to run async code in Meteor.

Basic async

Sometimes we need to run async code in Meteor.methods. For this we create a Future to block until the async code has finished. This pattern can be seen all over Meteor's own codebase:
