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.

- New to webdev, seen post where classes are frowned upon in nodejs. So, is this tutorial by Ben Awad relevant today?
-
I Learned so much from this Fullstack project.
I just finished the React, Graphql, and typescript project by benAward. It is a 14-hour wonderful tutorial.I was thinking Are there any other videos on YT that you find very useful?Other than just a random 4-5 hour tutorial. What are some of the videos that you find very helpful?
-
No meds! Need to learn React urgently.
I like this guy: https://youtu.be/I6ypD7qv3Z8
- Using Apollo Studio with a PostgreSQL database
- Example typescript project repos?
- Tutorials on Node.js that aren't boring and actually DO something?
-
Am I good enough to apply for a entry level Frontend job?
Initially I was following this Youtuber Ben's course, a full stack project which is built on Nextjs and graphql, but I know that Rest api is still the norm, and I wanna consolidate my knowledge with it, so I build these two:
-
Norm website with every episode of NML, bunch of Norm videos organized by Youtube channel, tributes, and upvote ranking system for NML jokes
I've been "learning" for awhile now so no worries. And yeah I have some old projects that broke over time because of the dependency issue too, big pain. The tech stack I've been using is based on Ben Awad's tutorial, idk if you've heard of him but you could probably pick up on how to use next.js of you go through it, pretty in depth: https://youtu.be/I6ypD7qv3Z8

Watch this and follow along https://youtu.be/I6ypD7qv3Z8

Officially given up on trying to get a job as a software developer
For your review, a solid day of humorous while useful info: https://youtu.be/I6ypD7qv3Z8

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! :)

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
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.

GraphQL Trades Complexity
you would fetch these 1000 rows via dataloader that batches all requests for this relation to a single query... solving the n+1 issue
