When building web applications you’ll often be using services on the client that require authentication. A common way client-side SDKs like Ably authenticate themselves is by using server-side API endpoints that generate and return access tokens. Using access tokens allows you to keep your service’s secrets on the server and instead issue time-limited and scope-limited tokens to a client. Some services even let you create revocable tokens for added security.

To update a document in MongoDB, I used to fetch it, update the values, and save back the entry. I would question the need for an update method. Looking back, it's evident that performance optimizations were hardly a concern when working on a personal project. Working with a larger dataset is a whole different story, though. This is where no-code tools can't help. In this article, I'll share some of my learnings when it comes to working in MongoDB with millions of documents.

We are thrilled to announce the latest addition to N|Solid Pro - the N|Solid Copilot, a groundbreaking AI-powered assistant designed to revolutionize your Node.js development experience. This innovative tool is a leap forward in Node.js application observability and security, it’s like having a Node expert on-call. View of N|Solid Pro Console with the Copilot drawer open allowing a user to interact with the AI Assistant.

NodeJS is a JavaScript runtime environment for running JavaScript applications outside the browser environment. It’s asynchronous and event-driven, meaning it doesn't block the event loop - making NodeJS highly suitable for the development of server-side web applications. With around 50,000 open source packages available through npm (Node Package Manager), NodeJS facilitates the seamless backend extension. The GitHub repository has 99k stars and 27.5k forks demonstrating an active community.

Because of the asynchronous nature of Node.js, it's crucial you set timeouts to ensure the responsiveness of your application. Node.js timeouts help prevent indefinite waiting and let your backend handle situations where tasks take longer than expected. Thanks to timeouts, you can control the maximum duration allowed for incoming and outgoing requests. In this article, we'll look at the different types of timeouts and how to set them in vanilla Node.js and Express.

In November of 2014, when NodeSource was still a small consulting group, my teammates Dan Shaw, Rod Vagg, and I were having dinner after a customer engagement, discussing how to bring Node.js production deployments to the same level of polish and tooling capability of the other runtimes our customers were already employing.

Node.js v21, the latest Node update, is now available as a stable release. It supersedes v20 in the'Current' release line, which has been promoted to the long-term support (LTS) channel as of 24 October. This new version stabilizes the fetch and WebStreams API, adds a built-in WebSocket client, improves support for ES modules, and brings some notable performance improvements (as well as a customary update of Node.js dependencies such as V8).

As a developer, choosing the right Websocket Node library to integrate into your realtime application project can be a humbling experience. You are faced with a lot of choices that offer different capabilities and features that will allow you to build scalable and efficient applications. However, given the constantly changing landscape, a crucial question remains: have you selected the most suitable one? Are there other options that could enhance your project even more?
