Building applications with gRPC is becoming an increasingly popular choice because of its performance and scalability. gRPC provides many benefits over traditional REST-based services, such as faster response times, better performance, and simpler code structure. In this comprehensive guide, we will walk you through the process of building a gRPC server using Node.js.

Test coverage plays a key role in providing bug-free experiences to users. At the same time, writing and maintaining test scripts for different web browsers is cumbersome and time-consuming. Fortunately, there is a solution! Playwright is a cutting-edge tool that makes it easy to automate modern web browsers. Through its powerful API, you can write end-to-end test scripts that run smoothly on different browsers. In this article, we'll cover: Let's dive straight in!

Application Programming Interface, or API, development is a critical aspect of modern software engineering, enabling diverse software systems to interact and share data seamlessly. The API serves as a contract between different software applications, outlining how they can communicate with one another. Two of the most popular architectural styles for building Web APIs are Representational State Transfer (REST) and GraphQL.

The beauty of Node is that while the main event loop runs in a single thread, some expensive tasks are automatically offloaded to a separate worker pool. These include the I/O-intensive DNS and File System (except fs.FSWatcher()) APIs, as well as the CPU-intensive Crypto and Zlib APIs. All these have a synchronous variation which will block the main thread. This is generally how Node accomplishes concurrency while running on a single thread.

Seattle, WA, June 28, 2023 — On stage at Collision Conf in Toronto, NodeSource, Inc., the leader in enterprise-grade solutions and support for Node.js, made two big announcements: the private beta of its groundbreaking AI Assistant, "Adrian," designed to revolutionize the way developers and DevSecOps analyze, optimize, and secure Node.js applications, and that it’s open-sourcing its Node.js runtime to enable developers access to the most advanced runtime available.

Puppeteer is a powerful browser automation library for web scraping and integration testing. However, the asynchronous, real-time API leaves plenty of room for gotchas and antipatterns to arise. This article is part of a series, starting with Avoiding Puppeteer Antipatterns and Puppeteer in Node.js: Common Mistakes to Avoid. In this post, we'll add another dozen antipatterns to the list. There will be no overlap with previous installments, so you may wish to start with those.

As a developer supporting a growing business, you’ll likely spend a lot of time thinking about scaling. We live in a wonderful time to be solving scale problems. Computers are so fast and capable that many of the development decisions you make when writing backend systems won’t noticeably impact performance(until your app reaches an absolutely massive scale). If this weren’t the case, we’d all be writing web servers in C.

The npm createerror package is a helper that allows you to easily create custom error classes in Node.js. It provides a simple API to define and extend error classes with customizable properties and methods.

Almost every modern web browser includes a powerful suite of developer tools. In our previous blog-post we covered How to Measure Node.js server response time with N|Solid, read more 👉 HERE. The developer tools have a lot of capabilities, from inspecting the current HTML-CSS and Javascript code to inspecting the current ongoing network communication client-server.

As software developers, we constantly face new challenges in an ever-changing ecosystem. However, we must always remember the importance of addressing performance and security concerns, which remain at the top of our priority list. To ensure that our applications based on Node.js can meet our performance and scalability needs without compromising security or incurring costly infrastructure changes, we must be aware of the importance of network optimization in Node.js.
