Description
Here´s the original solidity source code:
// SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception
// RUN: %soll %s
contract HelloWorld {
function sayHello() public pure returns (string) {
return "Hello World";
}
}
Javascript:
async function loadWasm() {
const wasmBinary = fs.readFileSync('C:\\Samuel\\Blockchain\\Flashloan-arbitrage-bot-uniswapV2_hardhat_AAVE_flashloan\\artifacts\\helloWorld.wasm');
const importObject = {
ethereum: {
finish: function() {
}
}
};
const instance = await WebAssembly.instantiate(wasmBinary, importObject);
// Call the sayHello() function
const result = instance.instance.exports.sayHello();
console.log("Result:", result);
}
loadWasm();
Output:
Exported Functions and Objects: [ 'memory', 'main' ]
module: Module [WebAssembly.Module] {}
instance: [Function: 2]
exports: Module [WebAssembly.Module] {}C:\Samuel\Blockchain\Flashloan-arbitrage-bot-uniswapV2_hardhat_AAVE_flashloan\runarb.js:46
const result = instance.instance.exports.sayHello();
^
TypeError: instance.instance.exports.sayHello is not a function
Would appreciate your help since I have followed the original steps guidance for solidity .sol compilation under README section. FYI there wasn´t any issue in generating the helloWorld.wasm object and can see hexadecimal byte codes inside the file which means the compilation process must have worked ok. Thank you!
