Hello Bun: How Sveld now deploys 2x faster on GitHub and Render

Eric Liu, a UX engineer at Render, explores the benefits of using Bun, a JavaScript and TypeScript runtime, by migrating the Sveld open-source library from Yarn and Vitest to Bun across build, test, and deployment stages on GitHub Actions and Render. The transition, which involved updating package management, testing, and CI/CD workflows, resulted in significant performance improvements, including 2x faster CI/CD processes and package installs 2-20x faster on GitHub Actions. Liu highlights Bun's ability to streamline development workflows through its Glob and Shell APIs, offering improved readability and reduced dependencies. Despite Bun's advantages, Liu notes that TypeScript and npm remained integral to the project due to Bun's current limitations in type checking and CommonJS support. The article encourages developers to experiment with Bun to leverage its speed and simplicity in their own projects on Render.
