![]() Removes external network requests for improved privacy and performance.Automatically optimizes your fonts, including custom fonts.13 introduces a brand new font system that: Learn more about the codemod or check out the documentation. pages directory when run from the root: npx next-image-to-legacy-image. For example, this command would run the codemod on your. We've provided a codemod that will automatically update your existing usage of next/image to next/legacy/image. The old Image component was renamed to next/legacy/image. Learn more about the Image component or deploy an example to try it out. The app/ directory can be incrementally adopted from your existing pages/ directory.Creating routes inside `app/` requires a single file, `page.js`: // app/page.js // This file maps to the index route (/) export default function Page ( ) Further, you can nest layouts, and colocate application code with your routes, like components, tests, and styles. The app/ directory makes it easy to lay out complex interfaces that maintain state across navigations, avoid expensive re-renders, and enable advanced routing patterns. The app directory can be incrementally adopted from your existing pages/ directory. Support for Data Fetching: async Server Components and extended fetch API enables component-level fetching.Streaming: Display instant loading states and stream in units of UI as they are rendered.Server Components: Making server-first the default for the most dynamic applications.Layouts: Easily share UI between routes while preserving state and avoiding expensive re-renders. ![]() The pages directory will continue to be supported for the foreseeable future. ![]() You can use Next.js 13 with the pages directory with stable features like the improved next/image and next/link components, and opt into the app directory at your own pace. The app directory is currently in beta and we do not recommend using it in production yet. This is a follow-up to the Layouts RFC previously published for community feedback. Today, we're improving the routing and layouts experience in Next.js and aligning with the future of React with the introduction of the app directory. Update today by running: npm i app Directory (Beta) Next.js 13 and the pages directory are stable and ready for production. Improved next/link: Simplified API with automatic.New (beta): Automatic self-hosted fonts with zero layout shift.New next/image: Faster with native browser lazy loading.Turbopack (alpha): Up to 700x faster Rust-based Webpack replacement.app Directory (beta): Easier, faster, less client JS. ![]() You can view the results here and the full benchmarking code here.As we announced at Next.js Conf, Next.js 13 (stable) lays the foundations to be dynamic without limits: We had a bit of difficult showing beneficial results for async and still unsure whether these results are a good reflection of the benefits of async. If you want a batteries included and ops-free experience, try out Shuttle. Maybe await a future post digging deeper into async in Rust! Shuttle: Stateful Serverless for RustÄeploying and managing your Rust web apps can be an expensive, anxious and time consuming process. This post is a introductory look into writing async Rust. gives a good overview of the status of async language features and other things in the async ecosystem. The async side of the Rust language is still in heavy development and can only can get better from here. If you want to read more about writing async the there is the official Rust async book and Tokio has a brilliant tutorial. To keep this post short and to the basics we will stop here. The above code starts both requests and then waits for the response from both, joining them in a resulting tuple. Rather than getting weather then getting the news. get ( "" ) let (weather, news ) = tokio :: join! (weather, news ). = 100 to Cargo.toml (or if you have cargo-edit installed: cargo add tokio -F full)
