Recap: Next.js Conf 2021

After the success of last year's Next.js Conf, the conference's first edition, expectations were relatively high. The conference is not only about speakers sharing interesting talks about Next.js, but it also features Vercel's team members sharing announcements related to the platform.

The event started with a talk given by Guillermo Rauch, Vercel's CEO. During the keynote, he talked about the presence of Next.js and Frontend development before the announcement of Next.js 12.

The new version of the framework brings several new features and improvements:

• New Rust compiler offers 3x faster Fast Refresh (next dev) and 5x faster build times (next build).
• Built-in support for ES Modules and experimental support for URL Imports.
• Included Middleware as useful for authentication, A/B testing, feature flags, and more.
• Support for React 18 and React Server Components.

Besides the changes in Next.js, Vercel as a company presented new products:

• Next.js Live: Experiment with real-time collaboration for your team. Code, chat, draw and edit directly from your browser.
• Vercel Checks: Extend the workflow of your application with end-to-end reliability checks, built-in Web Vitals performance checks, and open API for integrations.
• Edge Functions: Move server-side logic to Vercel's Edge Network, deployed globally with zero cold starts.

After the keynote, different team members from Vercel went deeper into the details of the new features and products. You can watch all the talks here.

This year we had a great day, as with last year's Next.js Conf. Three different stages were full of speakers telling different stories and experiences. From a live coding session to create a GraphQL API, to using a headless browser to monitor the deployment of our applications. From creating a full-stack application with Next.js and AWS to image optimization.

Let's mention some of them.
