Incorporating JavaScript into a Rust app

WasmEdge brings together Rust’s performance and JavaScript’s ease of use In my previous article, I discussed how to run JavaScript programs in a WebAssembly sandbox. The WasmEdge runtime provides a lightweight, high-performance, and OCI compliant “container” for cloud-native JavaScript applications. However, JavaScript is a “slow” language. The reason to use JavaScript is mostly due to its ease of use and developer productivity, especially for beginner developers. WebAssembly, on the other hand, is capable of running high-performance applications written in languages such as Rust.…

WebAssembly Serverless Functions in AWS Lambda

Serverless functions save developers a ton of trouble managing the backend infrastructure. It also simplifies the development process as developers only need to focus on the business logic. This article is a step-by-step guide on how to write and deploy your own WebAssembly serverless functions on AWS Lambda, Amazon's serverless computing platform. In our demo, WebAssembly functions are executed with the WasmEdge runtime. The figure below shows the overall architecture of our solution.…

Networking support. Make network requests and run an HTTP server from your WasmEdge application. New and improved APIs. Embed WasmEdge functions in C, Rust, and Golang applications. Generic binary output for WasmEdge’s AoT compiler. Take advantage of AOT performance enhancements in cloud native platforms.…

Running JavaScript in WebAssembly with WasmEdge

WebAssembly started as a “JavaScript alternative for browsers”. The idea is to run high-performance applications compiled from languages like C/C++ or Rust safely in browsers. In the browser, WebAssembly runs side by side with JavaScript. Figure 1. WebAssembly and JavaScript in the browser. As WebAssembly is increasingly used in the cloud, it is now a universal runtime for cloud-native applications. Compared with Docker-like application containers, WebAssembly runtimes achieve higher performance with lower resource consumption.…

Rust and WebAssembly Serverless functions in Vercel

Vercel is a leading platform for developing and hosting Jamstack applications. Unlike traditional web apps, where the UI is dynamically generated at runtime from a server, a Jamstack application consists of a static UI (in HTML and JavaScript) and a set of serverless functions to support dynamic UI elements via JavaScript. There are many benefits to the Jamstack approach. But perhaps one of the most significant benefits is performance. Since the UI is no longer generated at runtime from a central server, there is much less load on the server and we can now deploy the UI via edge networks such as CDNs.…

WebAssembly Serverless Functions in Netlify

Netlify is a leading platform for developing and hosting Jamstack applications. In fact, the term Jamstack was coined by Netlify founder Mathias Biilmann in 2015. Netlify also hosts the annual Jamstack Conf. A Jamstack application consists of a static UI (in HTML and JavaScript) and a set of serverless functions to support dynamic UI elements via JavaScript. There are many benefits to the Jamstack approach. But perhaps one of the most significant benefits is performance.…

A Complete Guide to DCO for Open Source Developers

When you contribute code to an open-source project, such as WasmEdge, you are often asked to sign a DCO (Developer Certificate of Origin) to ensure that the project has the proper rights to use your code. However, signing the DCO could be confusing and error prone. It is a barrier for many potential open source contributors. In this article, I will teach you exactly how to sign a DCO for open source projects hosted on GitHub.…

AI Inference for Real-time Data Streams with WasmEdge and YoMo

YoMo is a programming framework enabling developers to build a distributed cloud system (Geo-Distributed Cloud System). YoMo's communication layer is made on top of the QUIC protocol, which brings high-speed data transmission. In addition, it has a built-in Streaming Serverless “streaming function”, which significantly improves the development experience of distributed cloud systems. The distributed cloud system built by YoMo provides an ultra-high-speed communication mechanism between near-field computing power and terminals. It has a wide range of use cases in Metaverse, VR/AR, IoT, etc.…

Extend your Golang app with embedded WebAssembly functions in WasmEdge

The GO programming language (Golang) is an easy-to-use and secure programming language that compiles into high-performance native applications. It is a very popular choice for writing software infrastructure and frameworks. A key requirement for software frameworks is the ability for users to extend and customize it with their own code. However, in Golang, adding user-defined functions or extensions to an existing app is not easy. Oftentimes, you need to integrate at the source code level by combining the source code for the framework and the user-defined functions.…
