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. 🛠️

Installation

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

npm install --save @wasmer/wasmfs

Quick Start

import { WasmFs } from "@wasmer/wasmfs";

const wasmFs = new WasmFs();

wasmFs.fs.writeFileSync("/dev/stdout", "Quick Start!");

wasmFs.getStdOut().then(response => {
  console.log(response); // Would log: 'Quick Start!'
});
