Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Parsing Lambda Error Logs in ReScript & Python
We need the Promise library as it is the best way to use Promises in ReScript. We utilize the Jzon library for deterministically parsing our JSON into sound ReScript types without using the super verbose Js.Json classify syntax. Finally, we have an Environment module to help our Lambda know if it’s running in a QA, Stage, or Production environment.

Which Language?
For promises, there's a proposal plus implementation with improvements that should be upstreamed soon. JS interop is actually pretty good, if you find the embedding syntax too ugly you can for the most part keep .js files and .res files and they'll work together.

Thinking in ReScript
Note that here I'm using the rescript-promise library, which will soon become a part of the core language.

Testing Serverless Applications on AWS
For context; the web application is built with React and TypeScript which makes calls to an AppSync API that makes use of the Lambda and DynamoDB datasources. We use Step Functions to orchestrate the flow of events for complex processing like purchasing and renewing policies, and we use S3 and SQS to process document workloads.

Serverless APIs
AWS AppSync I'm keeping this section a bit shorter for you all, since AppSync is not something I have actually used personally, but have heard great things about. AppSync is another API option AWS has made available specifically for applications that want to take advantage of GraphQL or a Publish/Subscribe model. The GraphQL model may be of interest to front end developers that need to query multiple sources of data from one API endpoint, like databases or microservices. The Pub/Sub model I am more familiar with in the IoT hardware-communicates-with-software aspect, however this is also powerful for frontend developers looking to take advantage of real-time updates with serverless WebSocket connections. With AppSync, you also have caching, offline data synchronization, and real-time updates. You can learn more and check out the developer docs on the AWS Website.

React Signup/Login/Account Settings application With Amplify
Amplify is a set of tools that allows full-stack web and mobile developers to create and build apps. It makes using AWS services, like our Cognito identity and access management service, or our managed GraphQL service AppSync, much simpler and straight forward to use.

Building Serverless Web Applications with React & AWS Amplify
Appsync is the AWS service focus on creating flexible APIs, and Amplify is the framework that combines multiple AWS tools to help you build any type of Application.

Using GraphQL with DynamoDB is Cool
If you're building an AppSync/GraphQL API for that, yeah, that's a problem, better to use relational like Postegres.

Strategies to test AWS AppSync VTL templates
AWS AppSync is a serverless GraphQL and Pub/Sub API service that many developers love. Turing the complex job of creating and managing a GraphQL API with real-time capabilities into a few lines of IaC (or clicks in the console) is a great win for AWS serverless developers.

Ruminations on ValueObjects, DataTransferObjects, Back-end For Front-ends, and Functional Programming Data Modelling
In the case of microservices/Lambdas required to respond to GraphQL/AppSync, they have to follow the GraphQL contract and provide all data. So they'll often end up making multiple calls, mapping these DTO's to their own VO's that have all the data they need.
