wat2ta

A command-line tool to convert WebAssembly Text Format (WAT) files into JavaScript Uint8Array representation.

Prerequisites

• Node.js (>=14.0.0)
• wasm-tools

Installation

npm install -g wat2ta

Usage

wat2ta <wat-file>

Example:

$ cat example.wat
(module
  (func (export "add") (param i32 i32) (result i32)
    local.get 0
    local.get 1
    i32.add))

$ wat2ta example.wat
const wasmCode = new Uint8Array([0, 97, 115, 109, ...]);

The output can be used directly in JavaScript code to instantiate a WebAssembly module:

const wasmCode = new Uint8Array([...]); // Output from wat2ta
WebAssembly.instantiate(wasmCode).then(obj => {
  // Use the WebAssembly instance
});
