Migrating from v1 to v2

The v2 introduces notable changes including new features, performance improvements and new target support like ARM64 and OSes like FreeBSD.

This version v2 was re-written almost from scratch on top of Hyper and Tokio runtime which gives us the Rust asynchronous ability by default and the latest HTTP/1 - HTTP/2 implementation improvements. However, it still tries to keep the same principles of its v1: lightness and easy-to-use. Therefore migration should not be a big deal.

v2 breaking changes

This major v2 has few breaking changes. However, migration should not represent a problem.

Tip

It is always worth recommending that you test a major server version upgrade like this first with your application(s) in a development environment or similar.

Please have in mind the following changes in v2:

  • The server now supports only a root directory path (via --root or its equivalent env) so an assets path option is no longer required.
  • Cache-control headers are arbitrarily applied to assets. See control headers examples for more details.
  • OpenSSL TLS for HTTP/1 is no longer supported, instead for the HTTP/2 & TLS (via --http2 option) the server uses h2 which is on top of Rustls. It means that instead of using a .p12 or .pfx file you can now use only a certificate file along with its private key. See HTTP/2 & TLS examples for more details.

The rest of the known options are equivalent to v1 (except the new ones of course).
