A meta-registry for WebAssembly

Run your first component

Install the CLI, then go from an empty directory to a running wasi:http server.

1. 1

   Install the CLI

   Grab the component CLI for your platform. We’ve picked the command that matches your system. Copy it and run.

   Install the CLI

   Linux $
2. 2

   Initialize a project

   Scaffold a project in the current directory. This writes a wasm.toml manifest and a wasm.lock.toml lockfile so dependencies resolve to exact, reproducible versions.

   Initialize a project

   $ component init
3. 3

   Add a dependency

   Add a dependency from any OCI registry. Here we pull in ba:sample-wasi-http-rust (a ready-made wasi:http server) and record it in your manifest and lockfile.

   Add a dependency

   $ component install ba:sample-wasi-http-rust
4. 4

   Run the server

   Run the server you just installed. component run fetches the component if needed and serves it on localhost:8080.

   Run the server

   $ component run ba:sample-wasi-http-rust

   Send a request
