What is @webassemblyjs/helper-module-context?
The @webassemblyjs/helper-module-context package is part of the WebAssemblyJS project, which provides tools for compiling and manipulating WebAssembly modules in JavaScript. This specific package helps manage the context of a WebAssembly module, such as its imports, exports, and other metadata, facilitating the manipulation and analysis of WebAssembly code.
What are @webassemblyjs/helper-module-context's main functionalities?
Managing Imports
This feature allows developers to retrieve and manage the import statements of a WebAssembly module. The code sample demonstrates how to obtain the context from an AST and log the module's imports.
const { getModuleContext } = require('@webassemblyjs/helper-module-context');
const ast = ...; // WebAssembly AST obtained from parsing
const context = getModuleContext(ast);
console.log(context.getImports());
Managing Exports
This feature enables the handling of export statements within a WebAssembly module. The code shows how to extract and log the exports from the module context.
const { getModuleContext } = require('@webassemblyjs/helper-module-context');
const ast = ...; // WebAssembly AST obtained from parsing
const context = getModuleContext(ast);
console.log(context.getExports());
Accessing Module Types
This functionality provides access to the types defined within a WebAssembly module, which is crucial for understanding and manipulating the module's structure. The example code fetches and displays these types.
const { getModuleContext } = require('@webassemblyjs/helper-module-context');
const ast = ...; // WebAssembly AST obtained from parsing
const context = getModuleContext(ast);
console.log(context.getTypes());
