About the project

mod_wasm is an Apache Server (httpd) module to run WebAssembly modules and reply to HTTP requests with them. Currently, Apache Server runs the 31% of all websites you access every day.

By bringing WebAssembly to its ecosystem, you will be able to:

• Run existing applications from many different languages without modifying them
• Run unstrusted third-party code in a sandboxed and secure environment
• A security based capability-model that ensures applications only have access to the resources you configured

Internally, mod_wasm is composed by two different libraries:

• mod_wasm.so: the extension module for Apache Server
• libwasm_runtime.so: a high-level C-API to manage WebAssembly modules via Wasmtime

Try it

We created a container that includes Apache Server, mod_wasm and a few examples:

1. Run the container:

   docker run -p 8080:8080 ghcr.io/vmware-labs/httpd-mod-wasm:latest

2. Now, open your browser at:

We also prepared more examples you can play with.
