fs
wasmFs.fs: MemFs
​memfs' node fs implementation object. See the node fs documentation for API usage.
NOTE: The functions on this fs implementation can easily be over-ridden to provide custom functionality when your Wasm module (running with @wasmer/wasi) tries to do file system operations
const wasmFs = new WasmFs();
​
const originalWriteFileSync = wasmFs.fs.writeFileSync;
wasmFs.fs.writeFileSync = (path, text) => {
  console.log("File written:", path);
  originalWriteFileSync(path, text);
};
​
wasmFs.fs.writeFileSync("/dev/stdout", "Quick Start!");
​
// Would log: "File written: /dev/stdout"
