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.

Infinite loop pattern to poll for a queue in a REST server app
You could utilize a wrapper like sqs-consumer. Check out their implementation.

How to Instrument AWS Services with OpenTelemetry
To receive the messages from the queue, we will use the sqs-consumer library. The service will receive messages describing newly created orders. After some processing, it will change the order status in the table to ‘completed’.

Knock and Open Source
As we built out this new system, we looked at the current module ecosystem to determine if anything would fit our needs to keep this queue cleared. Unfortunately, the best module we could find, sqs-consumer, did not support FIFO queues and the issues indicated they did not have any intention to do so. Therefore, we wrote sqsiphon. Our library heavily borrows from the public interface of sqs-consumer, but is implemented in a much different way. In particular, sqsiphon leverages the Node.js event loop through setImmediate to build the polling mechanism instead of relying on SQS's "long polling" feature. Additionally, sqsiphon utilizes the JavaScript prototype to reduce reliance on expensive closures. As a bonus, OpenTracing support is built-in to sqsiphon so that applications built with it can be monitored effectively. The result is a library that can poll SQS extremely quickly while requiring very little overhead.

Hono vs. H3 vs. HatTip vs. Elysia - modern server(less) replacements for Express
Since "Express.js is an old framework that has not evolved for a long time. It's not a good choice for new projects since it can easily lead to security issues and memory leaks." -- H3. Which is also the case for Koa.

Instrumenting AWS Lambda functions with OpenTelemetry SDKs
In this example, we're using the serverless framework to quickly set up the Lambda function along with an API gateway for the entry point. The lambda function is a simple Koa REST API with a few functional endpoints.

Server-side Rendering (SSR) From Scratch with React
The initial step is to create our entry point, from where the page will be rendered. In this case, we will use the koa framework.

What is your ideal setup for new project for solo developers
Backend is more tricky. - RESTful APIs I prefer Koajs - For a RPC/microsevice, I have only used gRPC - For a CLI, yargs and inquirer

Why I selected Elixir and Phoenix as my main stack
There are lot of different frameworks out there. If you learn one, there is no guarantee that the next job you find will use the same. For example if you learn Express and the next one used Koa or Nest.
