After a week trying I was able to get into the DynamoDB single table design mindset, here are the resources and tools that helped me get in there:

• https://www.serverlesslife.com/DynamoDB_Design_Patterns_for_Single_Table_Design.html
• https://www.trek10.com/blog/dynamodb-single-table-relational-modeling/
• https://dynobase.dev/dynamodb-nodejs/
• https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/workbench.html

En los últimos días he estado utilizando Lucidchart y es una solución que me ha permitido crear diagramas de arquitectura de sistemas fácilmente, aunque no he utilizado toda su funcionalidad, he podido disenar de una manera gráfica la estructura de algunos sitios web, totalmente recomendable.

Today I used AWS Lambda Layers and it’s a game changer, they make it so easy to add versioned dependencies

I like AWS Amplify, but the size of the build was too big, TIL that they have modular imports, and I was able to reduce the size 2MB, while I wait for AWS SDK v3

Before:

import { Auth } from "aws-amplify";

After (better):

import Auth from "@aws-amplify/auth";

While learning DynamoDB, after a ton of tutorials and documentation, the moment it made click was when I saw the next table in the AWS SDK source code:

|             JavaScript Type           | DynamoDB AttributeValue |
|:-------------------------------------:|-------------------------|
| String                                | S                       |
| Number                                | N                       |
| Boolean                               | BOOL                    |
| null                                  | NULL                    |
| Array                                 | L                       |
| Object                                | M                       |
| Buffer, File, Blob, ArrayBuffer,      | B                       |
| DataView, and JavaScript typed arrays |                         |

TL;DR Hay que cambiar los enlaces de s3.amazonaws.com/<bucketname>/key a <bucketname>.s3.amazonaws.com/key antes del 30 de Septiembre del 2020.
