Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
@webassemblyjs/wast-printer
Advanced tools
The @webassemblyjs/wast-printer package is a tool for converting WebAssembly binary format (Wasm) into WebAssembly Text format (WAT), also known as WAST. This is particularly useful for debugging, optimization, and learning purposes, as WAT is a human-readable representation of WebAssembly code.
Printing Wasm to WAT
This feature allows you to parse a WAST string to create an abstract syntax tree (AST) and then print that AST back into a WAST string. It's useful for generating human-readable WAT/WAST from WebAssembly binaries or ASTs.
"const { parse } = require('@webassemblyjs/wast-parser');\nconst { print } = require('@webassemblyjs/wast-printer');\nconst wast = '(module)';\nconst ast = parse(wast);\nconst output = print(ast);\nconsole.log(output);"
The 'wabt' package is a set of tools built around the WebAssembly Binary Toolkit. It includes functionality to convert Wasm binaries to WAT and vice versa, similar to what @webassemblyjs/wast-printer offers. However, 'wabt' provides a broader set of utilities for WebAssembly manipulation, including validation and execution of Wasm code.
Binaryen is a compiler and toolchain infrastructure library for WebAssembly, written in C++. It has bindings for Node.js ('binaryen' npm package), allowing similar functionalities to @webassemblyjs/wast-printer, such as converting between Wasm and WAT. In addition to printing and parsing, Binaryen focuses on optimization, providing tools to generate and optimize WebAssembly code programmatically.

import { print } from "@webassemblyjs/wast-printer"
console.log(print(ast));
