“In 2022, I had an idea that could decrease the size of all newly-published npm packages by about 5%, and it was completely backwards compatible. This would have improved performance and reduced storage costs.”

“I eagerly pitched this idea to the npm maintainers, convinced it was a clear win. But after a few months, my proposal was rejected. To be clear: I think this was the right call!”

“ES Module Shims 2.0 is now live, a comprehensive 13KB polyfill for import maps, multiple import maps, CSS & JSON imports, Wasm modules and Source Phase imports.”

“If you don’t know what all of these features are, they are covered below, but first and most importantly I want to highlight one of the major new features in 2.0: TypeScript type stripping support.”

• Boundaries Experimental: A first look at Boundaries in Turborepo
• Terminal UI improvements: Persistent preferences and new features
• Watch Mode caching Experimental: Develop faster in Watch Mode
• Circular dependency recommendations: Adopt Turborepo in large repos more easily
• schema.json in node_modules: Versioned configuration validation from within your repository
• ESLint Flat Config support: eslint-config-turbo and eslint-plugin-turbo updated for ESLint v9
