mod_wasm is an Apache Server (httpd) extension module able to run and serve WebAssembly binaries as endpoints.
The first version (v0.1.0) was unveiled at the ApacheCon North America on Oct 3rd, 2022 (see the slides). In addition, a full-detailed article was published at VMware's Wasm Labs page.
mod_wasm can be useful in the different scenarios:
- Run existing applications from a variety of languages without modification.
- Execute untrusted third-party code in a secure environment without using containers.
- The Wasm capabilities model allows to enable/disable capabilites per HTTP request.
