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.…

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.…

🦕 Tutorial: Deno Apps with WebAssembly, Rust, and WASI

Deno is created by the original developer of Node.js, Ryan Dahl, to address what he called 10 things I regret about Node.js. It did away with the NPM and the infamous node_modules. Deno is a single binary executable to run applications written in TypeScript and JavaScript. However, while TypeScript and JavaScript are suitable for the majority of web applications, they could be inadequate for computationally intensive tasks, such as neural network training and inference, machine learning, and cryptography.…
