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! :)

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.

Building a README Crawler With Node.js
To execute the algorithm, we will use Node.js (for the JavaScript runtime) and node-fetch (for network requests). This means we will run the code locally from the command line. For this project, we will have an output folder to store all the README data, as well as a list (queue) of repository URLs to visit. Before diving into the code, it is important to plan the input and output of the algorithm. For this web crawler, we will start at a valid GitHub repository page, which would be one URL string. After visiting each page with a README, we will export the data into a new file. Now lets cover the process of requesting a repository page from a URL. For this, we only care about saving the README file that is displayed, and we will ignore any other links that GitHub displays (such as the navbar). We will send a URL request with node-fetch, and retrieve the result of a HTML string. If we convert the HTML string to a DOM Tree, we can search for a specific element. GitHub stores the README file under a div with the class "markdown-body". We can use a library called 'jsdom' to use Browser API methods, and return a specific node.

5 Ways to Make HTTP Requests in Node.js
Node Fetch is a JavaScript library tailored for Node.js that simplifies making HTTP requests. It offers a straightforward and Promise-based approach for fetching resources from the internet or server, such as GET, POST, PUT, and DELETE requests. Designed for server-side applications, it's compatible with the Fetch API, allowing easy code transition between client-side and server-side environments.

CommonJS Is Hurting JavaScript
Would anyone be interested in an article about the crusade to move JS to ESM? I've been considering writing one, here's a preview:
Sindresorus wrote a gist "Pure ESM modules"[0] and converted all his modules to Pure ESM, breaking anyone `require`ing his code; he later locked the thread to prevent people from complaining. node-fetch released a pure ESM version a year ago that is 16x less popular than the CommonJS version[1]. The results of these changes broke a lot of code and resulted in many hours of developers figuring out how make their projects compatible with Pure ESM modules (or decide to ignore them and use old CommonJS versions)--not to mention the tons of pointless drama on GitHub issues.
Meanwhile, TC-39 member Matteo Collima advocated a moderate approach dependent on where your module will be run [2]. So the crusade is led not by the Church, but by a handful of zealots dedicated to establishing ESM supremacy for unclear reasons (note how Sindresorus' gist lacks any justifications). It's kind of like the Python 2 to 3 move except with even less rationale and not driven by the core devs.

Next-Level Technical Blogging with Dev.to API
The API is CORS-enabled, meaning you’ll have to use the getArticles() functions from your backend. For making the actual request, you can use the fetch() function, available since Node.js v18. For older versions of Node.js, you can use a fetch()-compatible library like node-fetch.

EOS bot
I am making a bot that is supposed to take data from Upland's database from the account "dcrawtu15ye". I am using autocode to take it and I have found some ways to use it but some of my code still comes back as null. I have been using the eos docs to find info and all it can do right now is get account info if I use console.log(await rpc.get_account('dcrawtu1u5ye'));. I am using the dependency node-fetch. I wanted to know if there is something wrong with the code below. I also used greymass from this list and this article supposedly might help too.

How to Parse RSS Feed in Javascript
The RSS feed's URL will then need to be requested over the network. The native fetch API of JavaScript will be used since it is the most efficient. It undoubtedly works in browsers, and it appears that Node has a pretty well-liked implementation of it.

Exploring the Most Commonly Used Folder Names in Popular NPM Packages
docs: Documentation is an essential part of any package, as it provides users with the information they need to understand how to use it and how it works. The documentation usually includes usage instructions, API documentation, and more. It can also be included directly in the repository's README.md file, but it's often split into multiple files and stored in this folder for ease of navigation and maintenance. Although the documentation files can be in any format, the most common one is Markdown. Example from node-fetch.
