By Paul Krill WebAssembly runtime maker Wasmer has unveiled py2wasm, a Python-to-WebAssembly compiler that transforms Python programs to the WebAssembly (aka Wasm) binary instruction format. Using a fork of the Nuitka Python compiler, py2wasm converts Python programs to Wasm, allowing them to run without interpreter overhead. Introduced April 18, py2wasm addresses a situation in which the performance of Python programs in WebAssembly has been less than ideal, Wasmer founder and CEO Syrus Akbary wrote in a blog post. Akbary said that py2wasm gets about 70% of native Python speed, and is about 2...

By Serdar Yegulalp WebAssembly was originally designed to give in-browser web applications a way to run portable, sandboxed, high-performance binaries. As WASM matures beyond the browser, new uses for the technology are emerging. Using WASM to build programmability and extensibility into applications is one use case that is gathering steam. The Extism software library lets you write programs that can interface with extensions written in WebAssembly. Extism handles the data and function-calling interface between code written in your host application and the WASM extensions. This lets you focus ...

By Matthew Tyson Promises are a central mechanism for handling asynchronous code in JavaScript. You will find them in many JavaScript libraries and frameworks, where they're used to manage the results of an action. The fetch() API is one example of promises at work. As a developer, you might not be familiar with creating and using promises outside of an existing product, but it's surprisingly simple. Learning how to create promises will help you understand how libraries use them. It also puts a powerful asynchronous programming mechanism at your disposal. Asynchronous programming with promises...

By Serdar Yegulalp A common problem with Python applications is how to share them with other people. Developers frequently use a web interface to solve this issue, presenting the app's functionality by way of a UI. But that solution works best when the application UI is a natural fit for web components. Data exploration apps can work like this, for instance, but they also require front-end components written in JavaScript for ideal interactivity. Streamlit is a Python library that aims to solve many of these issues at once. Using Streamlit, developers can create Python apps with web-based fron...

By Joydip Kanjilal A high-quality application must be stable, performant, scalable, and reliable. The reliability of an application depends on many factors, but one of the most important is resiliency, or the ability to withstand failures or faults during run time. In this article, we’ll see how we can bring resiliency to database connections in ASP.NET Core using Entity Framework Core. EF Core has a feature called connection resiliency that automatically retries failed database commands to maintain connectivity during transient errors or network instability. By encapsulating the logic for ide...

By Matthew Tyson In the first half of this article, we set up a web development stack and created a simple example application using Bun, HTMX, Elysia, and MongoDB. Here, we'll continue exploring our new stack while cleaning up and abstracting the example application's data access layer and adding more complex HTMX interactions. We'll also add another component to the tech stack: Pug, a popular JavaScript template engine that works well with HTMX and helps with configuring DOM interactions. The example applicationOur example application currently consists of a form and a table. The form lets u...

By Paul Krill Google has introduced Jpegli, a JPEG library for image encoding. The new library is intended to be faster, more visually pleasing, and more efficient than traditional JPEGs. Proponents of the technology said it has the potential to make the Internet faster and more beautiful. Announced April 3 and accessible from GitHub, Jpegli maintains high backward compatibility while offering enhanced capabilities and a 35% compression ratio at high-quality compression settings, Google said. Jpegli works by using new techniques to reduce noise and improve image quality. New or improved featur...

By Matthew Tyson Bun and HTMX are two of the most interesting things happening in software right now. Bun is an incredibly fast, all-in-one server-side JavaScript platform, and HTMX is an HTML extension used to create simple, powerful interfaces. In this article, we'll use these two great tools together to develop a full-stack application that uses MongoDB for data storage and Elysia as its HTTP server. The tech stackOur focus in this article is how the four main components of our tech stack interact. The components are Bun, HTMX, Elysia, and MongoDB. This stack gives you a fast-moving setup t...

By Paul Krill Google has announced plans to eventually merge its Angular and Wiz web frameworks. The company says it is already looking for ways that Angular could benefit from Wiz's superior performance, while Wiz could benefit from Angular's focus on developer experience. In a blog post posted by the Angular team on March 30, proponents said that Angular and Wiz were “better together.” The merge will happen "gradually and responsibly" over the coming years, according to the post. Google’s strategy is to steadily open-source Wiz features via Angular and follow an open model of development. A ...

By Paul Krill The latest version of the web rendering engine Babylon.js has arrived with performance and rendering enhancements to support 3D capabilities and more. Version 7.0 of the rendering and game engine was announced on March 28. Directions for getting started with Babylon.js can be found on GitHub. Procedural geometry in version 7.0, also called Node Geometry, lets users create complex geometry at runtime or build time. This removes the need to download large 3D assets. Instead, local machines or devices can use the CPU to create these assets. Also featured in Babylon.js 7.0 is support...
