Wasmer Pack

Continuous integration

(API Docs | Project 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 wasmer-pack-cli
$ wasmer-pack --version
wasmer-pack-cli 0.5.2

We also need the WAPM package we are generating bindings for. One option is to create your own, but for convenience we'll use the wasmer/wasmer-pack-cli package from WAPM.

$ curl -sSO https://registry-cdn.wapm.io/packages/wasmer/wasmer-pack-cli/wasmer-pack-cli-0.5.2.tar.gz
$ tar -xzvf wasmer-pack-cli-0.5.2.tar.gz
$ tree .
.
├── wapm.toml
├── wasmer-pack-cli-0.5.2.tar.gz
└── wasmer-pack.wasm

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

$ wasmer-pack python . --out-dir ./py
$ tree py
py
├── MANIFEST.in
├── pyproject.toml
└── wasmer_pack_cli
    ├── commands
       ├── __init__.py
       └── wasmer_pack.wasm
    ├── __init__.py
    └── py.typed

2 directories, 6 files

We can generate JavaScript bindings with a similar command

$ wasmer-pack js . --out-dir ./js
$ tree ./js
./js
└── package
    ├── package.json
    └── src
        ├── commands
           ├── wasmer-pack.d.ts
           ├── wasmer-pack.js
           └── wasmer-pack.wasm
        ├── index.d.ts
        └── index.js

3 directories, 6 files
