Netlify has been working on improving its serverless workflows, specifically the Netlify Functions feature. The new updates include a faster bundler using esbuild, which optimizes JavaScript functions by discarding dead code and filtering dependencies. This results in smaller and more performant functions. Developers can opt-in to test the new functionality now or wait for it to be enabled during the week of May 17. To use the new bundler, set the `node_bundler` property to "esbuild" in the `netlify.toml` configuration file. Additionally, Netlify has introduced an advanced configuration section to handle edge cases, such as dependencies that can't be inlined, and support for ECMAScript modules syntax. The new features aim to provide a better serverless workflow experience for developers.
