@webassemblyjs/wasm-gen
Advanced tools
The @webassemblyjs/wasm-gen package is a tool that allows for the generation of WebAssembly binary code. It is part of the WebAssembly.js project which aims to provide a set of tools to compile, decompile, validate, and manipulate WebAssembly modules. With wasm-gen, developers can programmatically create WebAssembly binaries using an Abstract Syntax Tree (AST) representation of the code.
Generating WebAssembly binary
This feature allows the generation of WebAssembly binary code from an AST. The code sample demonstrates how to create a simple WebAssembly module with no imports, one function, and no exports, and then encode it into a binary format.
const { encode } = require('@webassemblyjs/wasm-gen');
const t = require('@webassemblyjs/ast');
const module = t.module(
[],
[
t.func(t.indexLiteral(0), [], [], [])
],
[]
);
const binary = encode(module);
console.log(binary);
wasm-opt is a package that provides optimization tools for WebAssembly binaries. It is part of the Binaryen project and offers similar functionalities in terms of manipulating and optimizing WebAssembly code. Unlike @webassemblyjs/wasm-gen, which is focused on generation from AST, wasm-opt works directly on the binary and provides advanced optimization techniques.
The WebAssembly Binary Toolkit (wabt) is a suite of tools for WebAssembly, including a decoder, an interpreter, and a binary generator. It offers functionality similar to @webassemblyjs/wasm-gen but also includes additional tools for working with WebAssembly text format and running WebAssembly code. Wabt is more comprehensive, while @webassemblyjs/wasm-gen is more focused on generation from AST.
AssemblyScript compiles a strict subset of TypeScript to WebAssembly. It provides a high-level approach to WebAssembly module generation, which is different from the low-level AST manipulation provided by @webassemblyjs/wasm-gen. AssemblyScript is suitable for developers familiar with TypeScript who want to write WebAssembly modules in a language they are comfortable with.
