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.

Delving into the Black Magic of GraphQL DataLoader! 🌌✨
When I began working with GraphQL, I had concerns about the N+1 query problem. In my research, I came across the DataLoader pattern and its implementation on GitHub. While I explored various examples of its usage, I still struggled to grasp how it operates internally. Join me in delving a bit deeper into GraphQL DataLoader! :)

How to use DataLoader with Mercurius GraphQL
DataLoader: it is the standard solution to N+1 problem.

Best Practices in Testing GraphQL APIs
Additionally, you can use DataLoader or similar tools to optimize data fetching and avoid over-fetching or under-fetching data. Ultimately, performance and load tests ensure that your GraphQL API delivers optimal performance, meets response time expectations, and provides a smooth experience for users, even under heavy loads.

Migrating Netflix to GraphQL Safely
Dataloader (https://github.com/graphql/dataloader) eliminates many n+1 issues. Basically, entity requests are queued up during evaluation of the query and then you can batch them up for fulfillment. It’s a great addition to other asynchronous contexts as well.
WRT random requests, there are libraries for query cost estimation you can use as a gate.
The most common practice is to turn N+1 into 1+1 using dataloaders (https://github.com/graphql/dataloader for JS, there are equivalents for most implementations). The N resolvers invoke a single batched loader which receives a list of keys and returns a list of values.

SQL vs. NoSQL - cutting through the Tech Twitter noise
Let's take Payload, for example. Surprise, surprise. We have a relationship field, and it can store IDs to other related documents which are seamlessly merged in when you retrieve documents from the DB. We leverage the dataloader pattern to batch together all "populations" required for a given query, returning them all super fast and with as few separate queries to the DB as possible. We actually even outperform SQL-based frameworks quite a bit. In a purely relational test, we were 3x faster than Directus and 7x faster than Strapi while both were running Postgres, and we were on MongoDB.

Typesafe, (almost) Zero Cost Dependency Injection in TypeScript
The one example of using Scoped dependency that comes to my mind, it's HTTP request level caching for libs like dataloader.

Speed test - Payload vs. Directus vs. Strapi
We knew that Payload was fast and we place a lot of emphasis on ensuring that it performs as quickly as possible, but with our recent addition of the dataloader pattern, our result surprised even us.

Implementing JWT Authentication in a Golang Application
JWTs, or JSON Web Tokens, serve as compact and self-contained data structures for transmitting information securely between parties. JWTs specify the token type, contain claims about an entity, and ensure integrity through cryptographic signatures.

Rust: JSON Web Token -- some investigative studies on crate jwt-simple.
🚀 If we paste our own JWT tokens into https://jwt.io/, it should be decoded correctly, and we should see the information in Payload displayed as a JSON object. However, all tokens generated throughout this post always get reported Invalid Signature.
