Open Next Versions Save

:tada: OpenNext V3 is out :tada:

This is the V3 of OpenNext. It includes some breaking changes and cannot be used as a drop-in replacement for V2. If your IAC is using OpenNext V2, you will need to update it to use V3.

If you are using OpenNext V2, please refer to the migration guide to upgrade to V3.

New Features

• Add support for function splitting
• Add support for external middleware
• Custom config file support : open-next.config.ts
• Support for other deployment targets than lambda (Node.js, Docker and partial support for Cloudflare Workers)
• Allow for customizing the outputs bundle :
  • Wrapper
  • Converter
  • Incremental Cache (Fetch cache and HTML/JSON/RSC cache)
  • Tag Cache
  • Queue (Used to trigger ISR revalidation)
  • Origin Resolver (Only for external middleware)
  • Image Loader (Only for image optimization)
  • Invoke function (For the warmer function)
  • Create an open-next.output.json file for easier integration with IAC tools

• Edge runtime don't work out of the box anymore. You need to deploy them on a separate function see the config for more info
• Output directory structure has changed to support function splitting
• Removed build arguments in favor of open-next.config.ts

Internal Changes

• Use OpenNextNodeResponse instead of ServerResponse (It uses transform stream to properly handle the stream)
