@webassemblyjs/wasm-parser
Advanced tools
Package description
The @webassemblyjs/wasm-parser package is a tool for parsing WebAssembly binaries (.wasm files) into a format that is easier to interact with in JavaScript. It can be used to analyze and manipulate WebAssembly modules without having to execute them.
Parsing WebAssembly binaries
This feature allows you to parse .wasm files into an abstract syntax tree (AST) that represents the structure and content of the WebAssembly module.
const { decode } = require('@webassemblyjs/wasm-parser');
const fs = require('fs');
const wasmBuffer = fs.readFileSync('module.wasm');
const ast = decode(wasmBuffer);
console.log(ast);The 'wabt' package is a set of tools for WebAssembly, built around the WebAssembly Binary Toolkit. It includes functionality to convert between the binary and text representations of WebAssembly, as well as to validate and execute WebAssembly code. It is more comprehensive than @webassemblyjs/wasm-parser, offering a wider range of tools for working with WebAssembly.
The 'wasmparser' package is another WebAssembly binary parser that provides an API for parsing WebAssembly modules. It is designed for performance and can be used in both Node.js and browser environments. Compared to @webassemblyjs/wasm-parser, it may offer better performance and a different API design that might be preferred in certain use cases.
The 'binaryen' package provides a compiler and toolchain infrastructure for WebAssembly. It includes capabilities for optimizing WebAssembly modules, converting between binary and text formats, and generating WebAssembly code. While @webassemblyjs/wasm-parser focuses on parsing, 'binaryen' offers a broader set of tools for compiling and optimizing WebAssembly code.
