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.…

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.…
