Wasmer Pack

(API Docs | User Docs)

Import your WebAssembly code just like any other dependency.

Getting Started

The easiest way to get started by installing with the wasmer-pack CLI.

$ cargo install --git https://github.com/wasmerio/wasmer_pack
$ wasmer-pack --version
wasmer-pack-cli 0.2.3

The wasmer-pack command accepts input in the form of Pirita containers, so let's download a container we can generate bindings for.

$ curl -O https://registry-cdn.wapm.dev/packages/wasmer/tutorial-01/tutorial-01-0.1.0.webc

Now we've got everything we need to generate Python bindings to the wasmer-pack package.

$ wasmer-pack python tutorial-01-0.1.0.webc --out-dir py
$ tree ./py
./py
├── MANIFEST.in
├── pyproject.toml
└── tutorial_01
    ├── bindings
    │   ├── hello_world
    │   │   ├── bindings.py
    │   │   ├── __init__.py
    │   │   └── tutorial-01.wasm
    │   └── __init__.py
    ├── __init__.py
    └── py.typed

We can generate JavaScript bindings with a similar command

$ wasmer-pack js tutorial-01-0.1.0.webc --out-dir js
$ tree ./js
./js
└── package
    ├── package.json
    └── src
        ├── bindings
        │   ├── hello-world
        │   │   ├── hello-world.d.ts
        │   │   ├── hello-world.js
        │   │   ├── intrinsics.js
        │   │   └── tutorial-01.wasm
        │   ├── index.d.ts
        │   └── index.js
        ├── index.d.ts
        └── index.js
