@wasmer/wasmfs NPM

`@wasmer/wasmfs`

Isomorphic library to provide a sandboxed node fs implementation for Node and Browsers. 📂

Documentation for Wasmer-JS Stack can be found on the Wasmer Docs.

Features

This project heavily depends on memfs to provide the sandboxed fs implementation. 🙏😄

This package provides the following features:

In-memory file-system with Node's fs API using memfs. 🗄️
Scaffolds common files used by the Wasmer Runtime (e.g I/O Device files like /dev/stdout), to provide a similar experience to the Wasmer Runtime. 🔌
Provides convienence functions for grabbing Input / Output. ↔️
Allows overriding read/write of individual files to allow for custom implementations. 🛠️

For installing @wasmer/wasmfs, just run this command in your shell:
