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


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 |                         |
