@webassemblyjs/wasm-edit
Rewrite a WASM binary
Replace in-place an AST node in the binary.
Installation
yarn add @webassemblyjs/wasm-edit
Usage
Update:
import { edit } from "@webassemblyjs/wasm-edit";
const binary = [/*...*/];
const visitors = {
ModuleImport({ node }) {
node.module = "foo";
node.name = "bar";
}
};
const newBinary = edit(binary, visitors);
Replace:
import { edit } from "@webassemblyjs/wasm-edit";
const binary = [/*...*/];
const visitors = {
Instr(path) {
const newNode = t.callInstruction(t.indexLiteral(0));
path.replaceWith(newNode);
}
};
const newBinary = edit(binary, visitors);
Remove:
import { edit } from "@webassemblyjs/wasm-edit";
const binary = [/*...*/];
const visitors = {
ModuleExport({ node }) {
path.remove()
}
};
const newBinary = edit(binary, visitors);
Insert:
import { add } from "@webassemblyjs/wasm-edit";
const binary = [/*...*/];
const newBinary = add(actualBinary, [
t.moduleImport("env", "mem", t.memory(t.limit(1)))
]);
Providing the AST
Providing an AST allows you to handle the decoding yourself, here is the API:
addWithAST(Program, ArrayBuffer, Array<Node>): ArrayBuffer;
editWithAST(Program, ArrayBuffer, visitors): ArrayBuffer;
Note that the AST will be updated in-place.
