Package description

What is @webassemblyjs/wasm-gen?

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.

What are @webassemblyjs/wasm-gen's main functionalities?

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);
