Neo Decompiler Web Package

This folder contains the publishable npm package for the Rust crate compiled to WebAssembly. It adds a thin TypeScript wrapper over the wasm bindings so browser code gets a stable, typed API without duplicating the decompiler logic.

Build

From this directory:

npm install
npm run build:wasm

That runs wasm-pack build .. --target web --out-dir web/dist/pkg --features web --no-default-features followed by scripts/prepare-wasm-package.mjs, generating the wasm glue under web/dist/pkg/.

Then build the TypeScript wrapper:

npm run build:ts

For a full package build:

npm run build:package

Serve

From this directory:

python3 -m http.server 4173

Then open http://localhost:4173.

JS API

import {
  init,
  initPanicHook,
  infoReport,
  disasmReport,
  decompileReport,
} from "neo-decompiler-web";

await init();
initPanicHook();

const info = infoReport(nefBytes, {
  manifestJson,
  strictManifest: false,
});

const disasm = disasmReport(nefBytes, {
  failOnUnknownOpcodes: false,
});

const decompile = decompileReport(nefBytes, {
  manifestJson,
  strictManifest: false,
  failOnUnknownOpcodes: false,
  inlineSingleUseTemps: true,
  outputFormat: "all",
});

nefBytes should be a Uint8Array. manifestJson should be a UTF-8 JSON string.

The wrapper accepts camelCase JS options and translates them into the snake_case ABI expected by the wasm bindings. The published npm tarball includes the compiled TypeScript wrapper plus the wasm artifacts under dist/pkg/.
