Running hello-world.wasm

There are a number of ways to run a .wasm file with Wasmtime. In this tutorial, we'll be using the CLI, Wasmtime can also be embedded in your applications. More information on this can be found in the Embedding Wasmtime section.

If you've built the hello-world.wasm file (the instructions for doing so are in the previous section), you can run it with Wasmtime from the command line like so:

$ wasmtime target/wasm32-wasi/debug/hello-world.wasm
