On October 15, 2024, the second Next.js 15 RC was announced. The release candidate promises plenty of improvements and new features aimed at enhancing development efficiency and the overall user experience. Highlights include:
- Stable Turbopack – A bundler that speeds up development, providing faster rebuilds and hot reloading will become stable in the full update release. Designed to handle larger projects efficiently, it’s set to become the replacement for Webpack,though it remains an opt-in.
- Async Request APIs – A function meant to streamline server-side rendering by allowing data fetching to happen asynchronously. It’s expected to improve response times and reduce load on the client for faster initial page loads and smoother transitions.
- New <Form> Component – Designed for easy client-side navigation, the new component will reduce the need for manual form handling. Developers can now simplify user interactions since this component integrates easily with other Next.js features.
- TypeScript Support – Enhancements now allow TypeScript configurations directly in next.config.ts. As a result, the development flow will be more integrated, and the setup time reduced. Projects that use TypeScript will also enjoy greeted compatibility.
- Build and Observability Upgrades – The RC introduced new tools for build process monitoring and logging, designed to help developers troubleshoot more efficiently. These tools would offer detailed logs, streamlined integration with observability platforms, and optimizations for faster build times.
- ESLint 9 Compatibility – Developers will? benefit from improved linting rules, better integration, and improved error detection thanks to the adherence to the latest standards for code quality.
- Self-Hosting Enhancements – Improved documentation and tooling make it easier to configure, deploy, and scale applications on various infrastructure setups, resulting in a simpler setup of self-hosted environments.
These updates aim to improve performance, security, and the overall developer experience, reflecting Next.js’s ongoing commitment to evolving its ecosystem.
