spin-fileserver-example (JavaScript)

This is an example of using component composition to compose an example app with spin-fileserver, a reusable component for serving static files.

Prerequisites

• Spin v2.0+
• Rust
• cargo-component
• wac
• NodeJS
• componentize-js
• curl or a web browser for testing

Once you have Rust and NodeJS installed, the following should give you everything else:

rustup target add wasm32-wasi
cargo install cargo-component
cargo install wac-cli
npm install -g @bytecodealliance/jco @bytecodealliance/componentize-js

Building and Running

To build and run the example, run:

spin build -u

Then, in another terminal, you can test it using curl:

curl -i http://127.0.0.1:3000/hello

The above should return a response body Hello, world!, served up by the example app itself. All other URIs are handled by spin-fileserver, e.g.:

curl -i http://127.0.0.1:3000/foo.txt

curl -i http://127.0.0.1:3000/nonexistent.txt
