http-jsonify

HTTP JSONify

This is a simple Rust Wasm example that converts an incoming HTTP request to a JSON representation, and returns that as the response.

Prerequisites

• cargo >=1.75
• wash >=0.27.0
• wasmtime >=19.0.0 (if running with wasmtime)

BUilding

wash build

Running with wasmtime

You must have wasmtime >=19.0.0 for this to work. Make sure to follow the build step above first.

wasmtime serve -Scommon ./build/http_hello_world_s.wasm

Running with wasmCloud

Ensuring you've built your component with wash build, you can launch wasmCloud and deploy the full hello world application with the following commands.

Once the application reports as Deployed in the application list, you can use curl to send a request to the running HTTP server.

wash up -d
wash app deploy ./wadm.yaml
wash app get
curl http://127.0.0.1:8000
